There are three types of belts commonly found in automobiles: car fan belts, ribbed belts, and timing belts.

Automobile belt installation location: In automotive applications, it is mainly installed on the crankshaft of automobile engines to cams, water pumps, generators, air-conditioning compressors, power steering pumps and other positions.

1. The fan belt is a belt driven by a crankshaft. Its main purpose is to drive the engine fan and water pump.

2. The V-ribbed belt, also called air-conditioning belt, is used to drive the generator, air-conditioning compressor, and steering booster pump, and is hung on the crankshaft belt pulley, which is tightened by the air-conditioning belt tensioner. When this belt is damaged, the source will feel the power is heavy and there is no steering power. If the air conditioner is turned on, the air conditioner compressor will not start, so it cannot be cooled.

3. The timing belt is an important part of the engine's gas distribution system. It is connected to the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. The function of the timing belt is to open and close (time) the ignition sequence (time) of the piston stroke (up and down movement) of the valve when the engine is running. Under the action of "timing", it is necessary to maintain "synchronous" operation at all times.

The engine drives various auxiliary mechanisms through the belt drive, such as the compressor of the air conditioner, the power steering oil pump, and the alternator. If the belt slips or breaks, the related auxiliary mechanisms will not work properly, which will affect the normal use of the car lane. Therefore, it is necessary to regularly check the transmission belt.

There are many types of car engine belts. The type and length of the belt will be very different depending on the model and the location of use. It is best to provide the accurate model and engine model when buying. It is best to have the old belt removed for reference. Be sure to choose a car belt suitable for your vehicle.

October 21, 2019 12:38 AM Eastern Daylight Time

SHENZHEN, China--(BUSINESS WIRE)--Zhiyun, the world’s leading gimbal manufacturer announced the WEEBILL-S gimbal which was held at a special event in Bangkok, Thailand. The Weebill-S is designed for mainstream mirrorless and DSLR camera & lens combos. This new gimbal offers ultra-low latency image transmission in 1080p with an all-new TransMount Image Transmission Module. ViaTouch 2.0 turns your phone into a professional monitor and multi-functional remote controller.

Event Details

The event kicked off with an opening speech, a Zhiyun company and Weebill-S speech, a KOL speech, a special display and demonstration of the Weebill-S, dinner, and a lucky draw that concluded the events. There was a live streaming of the launch event on Zhiyun’s Global Facebook, Instagram, and YouTube accounts between 7pm – 9:30pm yesterday evening China time.

Brand Attendees

The event in Thailand was attended by Canon, Nikon, Sony, Panasonic, Olympus, and Fujifilm representatives and highlighted their participation with Zhiyun. Z Cam CEO, Kinson and co-founder Eric were in attendance.

Demonstration

Zhiyun had over 20 sets of the Weebill-S on site being displayed with the leading camera combos (Canon, Nikon, Sony, Panasonic, Olympus, Fujifilm, BMPCC, Z Cam). Attendees were able to test and play around with the Weebill-S to get a feel for the product and its potential. Also, at the event were Zhiyun’s global ambassadors from Holland (Chung Dha), Singapore (Sean Seah), and Australia (Rah Sharma) sharing their knowledge and experience with the Weebill-S gimbal.

Weebill-S Gimbal

The Weebill-S gimbal from Zhiyun is the latest and most lightweight gimbal to date. It is powerful, compact, and compatible with many devices. On display were the all-new TransMount Image Transmission Module, the ViaTouch 2.0 and SmartFollow 2.0 software, sync motion and wireless control, smart calibration, ease-of-use in mobility, focus strengths, and powerful and durable demonstrations. These are the qualities that sets the Weebill-S gimbal from the rest of the competition.

For more information about the WEEBILL-S visit WEEBILL-S product page and WEEBILL-S video.

About Zhiyun

Zhiyun Tech is a pioneer and a world leader in gimbals and stabilizers for both professional filmmakers and personal video creators. Learn more about Zhiyun Tech at www.zhiyun-tech.com or check us out on Facebook: Zhiyun Thailand or follow us on Instagram: @zhiyunthailand

After the massive success of the Kickstarter campaign for their SMOOTH-Q2 smartphone gimbal, Zhiyun is back with a new gimbal for DSLR and Mirrorless cameras: the Zhiyun Weebill-S. This compact and robust handheld gimbal is a follow-up to the previous Weebill LAB that was announced at Photokina 2018. Let’s take a closer look at it!

Zhiyun Weebill-S Design

Zhiyun has just announced their new handheld gimbal for mirrorless and DSLR cameras: the Zhiyun Weebill-S. This fresh stabilizer is a follow-up to the previous Weebill LAB, but it is not a replacement. Overall, the one-of-his-kind design is similar between the two. If it works, don’t fix it.

You can mount the included tripod – that double as a handle – in “normal” mode under the gimbal. That way, you can operate the Weebill-S like any other one-hand-gimbal. But, the neat feature is that you can also mount the tripod horizontally as a handgrip. In that position, it makes it easier to operate the gimbal in underslung mode and get low-to-the-ground shots.

The Zhiyun Weebill-S is also pretty compact, with a total height of just 297mm. It is powered by two 18650 interchangeable batteries, for a runtime of up-to 14-hours according to Zhiyun.

One thing that I like in the design of the Zhiyun Weebill-S is the locking switches on every axis. There is one dedicated switch on the Pan, Tilt and Roll axis.

These locks are helpful for transport purposes, so your gimbal doesn’t go in every direction in your bag without you noticing. Also, for balancing goals, you can adjust each axis at a time by locking the other two. These are the small design features that make your life easier and your job quicker.

But what’s new with the Zhiyun Weebill-S compared to the previous generations?

Zhiyun Weebill-S Features

The Zhiyun Weebill-S features new motors with a 300% improvement in motor torque and a 50% increase in responsiveness, according to Zhiyun. In short, it means that you can now mount and balance more massive setups like a Sony A7III + FE 24-70mm F/2.8 and Canon 5D4 + EF 24-70mm F/2.8.

The quick-release plate to mount your camera is now Manfrotto and Arca-Swiss compatible. Otherwise, there is no word from Zhiyun regarding the maximum payload the Weebill-S can take at the moment.

A new intelligent auto-tune feature should provide more stable and flawless stabilization results. Indeed, the Weebill-S can now automatically recognize the setup weight and auto-tune its power to adapt the camera setup best.

ZhiyunWeebillS_04

Zhiyun wholly redesigned the image transmission module. The new TransMount Image Transmission Module can be directly mounted under the quick release plate.

The features of the TransMount module are quite impressive: 1080P transmission at up to 30 frames per second, a 100-meter range, and a range of tools such as LUT/false color/focus peaking/zebra. Also, you can use the TransMount for live streaming purposes, but you can also connect up to three devices at the same time.

Zhiyun Weebill-S Control Features

The TransMount Image Transmission Module gives you access to the ViaTouch 2.0 eco-system. In short, ViaTouch turns your smartphone into a monitor and remote controller. If your camera is compatible, you can control/record/adjust the camera parameters through ViaTouch 2.0. For a complete list of the compatible cameras, please look at the Zhiyun’s inventory on their website here.

On the gimbal itself, there is a control wheel on the side of the bottom handle. You can use that wheel to control your focus electronically without the need for an additional follow-focus (if your camera is supported). But the control wheel can also pilot the Zhiyun TransMount Servo Zoom/Focus Controller (sold as an accessory).

There are several ways to aerate your fish tank, and these methods will be discussed in this article. Before discussing specific methods, it is important to address the surface area of ​​water in the fish tank. The larger this surface area, the more water is in contact with the air. This results in greater absorption of oxygen by water. Therefore, you should try to maximize the surface area of your fish tank.

Basic Oxygen and Carbon Dioxide Exchange Introduction

When your fish breathe, they absorb oxygen from the tank, and their body converts the oxygen to carbon dioxide and then exhales. Oxygen and carbon dioxide are also exchanged on the surface of the water. Carbon dioxide is released from the water into the air. This is important because if you don't let carbon dioxide escape into the atmosphere, your fish will die - it will only accumulate in the tank, causing your fish to slowly suffocate to death. You may need a carbon dioxide diffuser.

When carbon dioxide is released from water into the air, oxygen is also absorbed from the air into the water. This is important because it increases the oxygen content in the aquarium water and provides the fish with the oxygen they need to breathe. For this air exchange to occur, however, the surface tension of the water must be broken - this allows the carbon dioxide molecules to be released and oxygen to be absorbed. Agitating the surface breaks this surface tension and allows proper gas exchange.

Temperature and oxygen concentration

As your tank temperature rises, the oxygen content will decrease because your tank's water evaporation rate will increase. Therefore, the higher the temperature you keep in your tank, the more you need to know if your fish is getting enough oxygen. Once your temperature exceeds 800 degrees Fahrenheit, you may need to provide some aerating equipment listed below apart from the filter in tank.

What Common Aerating Equipment Are There

Filter

For many aquariums, a simple hob (hanging on back) filter will fully aerate your tank. Many filters have an output that drips water into the surface of the tank, thus providing sufficient surface agitation. This surface disturbance increases the surface area that is in contact with the atmosphere and therefore increases the absorption of oxygen. In addition, the good filter in tank fish filter, which is important because it moves the bottom water of the fish tank (water that cannot get oxygen from the air) to the top surface, which can increase the oxygen concentration.

Pros / cons of filters

-Help increase aeration / oxygen content

-Increase the water circulation in the tank, thus the surface area

-Rotate tank water up from the bottom

-May create blind spots depending on the location of the filter

Power Head

If your filter doesn't interfere with the surface enough or provide enough circulation, you can use a powerhead as well. The powerhead siphons water out of the tank and mixes it with the exhausted air. Many powerheads also allow you to adjust the amount of air they inhale, which allows you to adjust the number of bubbles generated (see the paragraph on bubble stones below to learn how bubbles help ventilation).

The powerhead can also be used to eliminate dead spots in the water tank-areas with particularly low water circulation. A carefully placed powerhead can increase the circulation of your tank in these areas. Filters, air stones, and decorations often fail to adequately aerate large aquariums. Therefore, powerheads are often the method of choice for large tanks. However, you can easily supply too much current in a small to medium-sized aquarium with powerheads, so be sure to buy a tank rated for smaller or buy a tank with adjustable flow.

Pros and cons of a powerhead

-Become a good source of supplemental aeration

-Can help deal with blind spots in the tank

-Can increase overall aeration

Air Stone

The air stone is a porous stone that is connected to an air pump and generates air bubbles in the fish tank. Many people think these pumps are too noisy, so they choose not to use air stones. However, placing the pump on a sponge usually reduces noise significantly. Some amateurs really like the bubble wall in the fish tank, so they will use it even without further inflation. In fact, it is not the bubbles that provide oxygen to the water (this is a common misconception), but the ability of bubbles to disturb the water surface and provide more water circulation helps increase the oxygen concentration in the water tank.

Pros and cons of Air Stone

-Can be installed in almost any tank

-Adjustable flow rate, suitable for any size tank

-Helps increase surface agitation and circulation

Although many factors play a role in keeping the fish healthy, aeration is one of the most important factors. Properly aerating the tank will allow your fish to breathe normally, which is important for good health. The most commonly used aeration equipment in fish tanks are filters, powerheads and air stones, which Senzeal can provide. Use any combination you like to give your fish the oxygen they need. We have external fish tank filter for sale, welcome to buy.

论文抄袭

论文抄袭 近年来常常发生在留学生身上。许多留学生刚到美国开始学习时，都很难快速适应当地的语言环境，尤其是长篇大论的英文写作更是让很多人都头痛不已。更让人崩溃的是，英文课作为一门必修课，是任何人都无法避开的，包括那些整日与公式和代码为伍，对于英文写作规范知之甚少的理工科学生。而这也恰恰是为什么许多学生都会踏进论文抄袭这个雷区的一个重要原因。

求真案例

C同学是一名美国西部某大学数学系的大二学生，上大学前英文成绩就不算太好，加上专业原因，平日里基本上都在和数字、几何打交道，甚至很少会需要他写一句完整的英文句子，这也使得他对于英文写作更加恐惧和排斥。但是完成一门英文写作课是毕业要求，即使再不情愿，C同学也只能硬着头皮去上这节课。不出所料，这门课让C同学头痛不已，上课时如听天书，对老师布置的作业也毫无头绪。课上也没有同专业或者认识的同学可以求助，找不到别人求助的他只好寄希望于网络，想借鉴一下别人的文章找思路。最后，他改写了一篇与自己看法相近的文章，然后提交了上去。结果可想而知，他的文章因为被怀疑是抄袭而被老师举报，需要与Dean谈话，并且参加听证会。

求真助力

C同学在接到通知后不知所措，立刻在朋友的介绍下联系了求真教育的紧急应对团队。负责人姚老师先安抚了慌乱的C同学的情绪，告诉他要保持镇定，事情还没到无可挽回的地步。随后，姚老师在最短的时间内为C同学做出了申诉方案，指导他如何逻辑清晰地向Dean陈述自己在写作方面的困难，并协助他完成了申诉信。随后，姚老师又和C同学反复模拟和Dean的交谈的情景以及听证会的过程，帮助他克服用英文交流的恐惧。最后，因为C同学在整个过程中表现的从容不迫，加之他认错态度诚恳，解释时也有条不紊，并给出了之后的改进方法，学校最终决定减轻对他的处分。随后，求真教育也为他提供了写作的学术辅导，帮助他顺利攻克了英文写作的难题。

求真寄语

求学过程中，我们难免会遇到自己不擅长的领域，有无法解决的麻烦，也会想走捷径，想钻空子，但请一定不要因此违反规定，触碰警戒线。如果真的遇到不能解决的难题，请记得随时联系求真教育，我们会提供最优质的服务，帮助你在危急处境中化险为夷。文章来源：https://indeededu.com

美本转学申请

学生：F同学

GPA：3.8+

TOEFL：98

申请专业：数学

录取学校：约翰霍普金斯大学、密歇根大学安娜堡分校、纽约大学等

求真案例

F同学刚在美国入读大一，他的爸爸就找到了求真教育咨询美本转学申请，因为听说孩子入读的排名60名左右的大学是一所party school，担心他荒废了学业。老师十分理解家长的担忧，学校大环境对孩子的影响确实非常大。在和F同学深入交流之后，老师发现他是个遇强则强的孩子，虽然在美本申请时条件平平，但是潜力很大，如果能从玩着学转变到认真学，这其中的飞越可能会让我们刮目相看。于是建议他们开始着手准备大三转学。

求真助力

大一期末考试结束后，F同学给申请老师的反馈是学校的课程难度一般，想拿A也不是太难。因此老师对他提出了更高的要求，课不能选水课，GPA不能低于3.8。基本的要求和选课谈妥后，老师们就开始着手另外一项重大工程：背景提升。在挖掘了F同学的家庭背景和实践经历后，老师给他安排了两个课外活动，一是社科类的，体现他对弱势群体的关注，通过调查研究并付诸实践，体现了他的思辨和行动能力；二是科研类的，跟着学校教授在国家重点实验室做了两个月研究，体现他的学习能力和科研素养。

有了一系列的铺垫，文书写作的过程可谓非常顺利。求真教育对于文书创作有着自己的原则，不深入挖掘不写文书，不做背景提升不写文书，不了解孩子不写文书。当做到了这三点后，文书就水到渠成了。文书老师把孩子对专业的理解和丰富的实践经历通通融入了主文书当中，呈现了F同学真实的想法和绝对的实力。

求真寄语

不出老师意料，在三月份时，F同学就收到了密歇根大学录取，但是大家心里都在期待着收到更好的消息。终于功夫不负有心人，半个多月后，我们收到了约翰霍普金斯大学抛来的橄榄枝。在众多申请的学校中，这算是F同学和他的父亲最最心仪的结果了。求真教育的老师们也由衷地为他们感到高兴！求真教育有多年美本转学申请的经验，越早进入服务能为申请收获更好的结果。文章来源：https://indeededu.com

Operation method of the staples used in surgery: An intestinal anastomosis is used to illustrate the use of the stapler. The anastomosis is sutured in the proximal intestine, placed in the staple holder and tightened. The stapler is inserted from the distal end, the central piercer of the stapler is threaded out and articulated with the central rod of the proximal stapler against the staple holder, and rotated close to the distal and proximal bowel walls. Adjust the distance between the staple holder and the base according to the thickness of the intestinal wall, generally by turning the hand tighter (with a tightness indicator pin on the handle).

Squeeze the closing anastomosis wrench to tighten the anastomosis, and the sound of the sound indicates that the cutting anastomosis is complete. Do not withdraw the anastomosis and check to see if the anastomosis is satisfactory and if other tissues, such as the mesentery, are embedded. After being dealt with accordingly, the anastomosis was unscrewed and gently pulled from the distal end to check for the integrity of the distal and proximal bowel resection rings.

Precautions for use of the stapler

(1) Before the operation, check whether the ruler and 0 scales are aligned, whether the assembly is correct, and whether the push-piece and tantalum nail are missing. A plastic washer should be installed in the resistor.

(2) The broken end of the intestine to be anastomosed should be fully free and stripped at least 2cm.

(3) The distance between the stitches of the purse suture should not exceed 0.5cm, and the margin should be 2~3mm so that too much tissue is easy to embed in the anastomosis and hinder the anastomosis. Be careful not to omit the mucosa.

(4) Adjust the spacing according to the thickness of the intestinal wall, with 1 to 2 cm being appropriate.

(5) Check the stomach, esophagus, and other adjacent tissues before hitting to prevent clamping into the anastomosis.

(6) The cut should be made quickly, and pressure should be applied at the end to make the staple into a "B" shape.

(7) Exit the surgical stapler gently and check whether the incised tissue is a complete ring.

Victor Medical Instruments Co., Ltd is a professional firm of auto surgical staplers and minimally invasive surgery equipment, we provide open surgical instruments.

DMF-Z Right Angle Electromagnetic Pulse Valve Product introduction:

The electromagnetic pulse valve is imported from abroad (also known as the diaphragm valve) is the compressed air "switch" of the pulse bag filter dust cleaning system is controlled by the output signal of the pulse injection controller, and the filter bag is cleaned by the row (chamber). Ash, so that the dust collector's resistance is maintained within the set range, in order to ensure that the dust collector processing capacity and vacuum efficiency.

DMF-Z Right Angle Electromagnetic Pulse Valve Features:

The DMF-Z electromagnetic pulse valve is a right-angle valve. The angle between the inlet and outlet is 90°. It is suitable for the mounting connection between the helium cylinder and the dust blower tube. The gas flow is unobstructed, and it can provide the turbulent gas flow that meets the requirements.

DMF-Z Right Angle Electromagnetic Pulse Valve working principle:

The diaphragm divides the electromagnetic pulse valve into two air chambers, front and rear. When the compressed air is turned on, the compressed air enters the rear air chamber through the throttle hole. At this time, the pressure of the air chamber presses the diaphragm against the output of the valve. The pulse valve is in the "closed" state.

The electric signal of the pulse injection controller causes the electromagnetic pulse valve armature to move, the air chamber vent hole opens after the valve, the rear chamber quickly loses pressure, the diaphragm moves back, the compressed air is blown through the valve outlet, and the electromagnetic pulse valve is "opened" status.

Pulse injection control instrument electrical signal disappeared, electromagnetic pulse valve armature reset, after the air chamber vent hole closed, the rear chamber pressure increased so that the diaphragm close to the valve output, the electromagnetic pulse valve is in the "closed" state.

Design principles for the runner system:

1. For the single plastic part and multiple cavities, the balanced runner (except special) should be used, that is, the position of each cavity gate and the size of the gate point are the same and the length of the runner is the same. To ensure uniform molding conditions in each cavity.

2. For multi products and multi cavities use non-equilibrium runner and gate point, the size of the nozzle or runner should be adjusted according to the distance of the flow to ensure that the cavities are filled as much as possible.

3. In order to reduce heat and pressure loss, the runner should be as short and straight as possible, and the radius should be added at the corner to ensure smooth flow. The surface of the runner must be polished with more than 600# sandpaper. If the part is mirrored, the runner must be polished with 1000# sandpaper.

4. The gate system should be designed cold slug well to prevent cold material entry into the cavity and affect the quality and appearance of the parts.

5. The gate system must be vented to ensure that the plastic melt fills all corners of the cavity, so that the cavity gas can be discharged smoothly.

6. The gate system should be able to prevent the plastic parts from shrinking mark, deformation, dimensional deviation and other defects. The gates are convenient to cutoff or cut automatically and do not affect the appearance of the product.

7. In order to improve the mass production efficiency, it is necessary to minimize the subsequent processing of the plastic parts when designing the gate. Automated mass production, when the gate is taken out, the robot is used as much as possible to shorten the cycle time.

8. For the plastic injection molding gate design, the diameter of the root should be no smaller than the runner. For materials with high brittleness such as PS, a double-sided 3° draft angle should be used. Preventing the breakage of the sprue and runner, while the runner breakage will cause trouble for mass production.

9. Making runner into a circular or U-shaped that is easy to process.

10. The design of the gate system should take into account the amount of runner material. To save costs and eliminate waste, the weight of the runner is controlled below 25% and cannot exceed 50% (special consideration for special parts).

11. When there are multiple injection points on a product, the influence of the size and position of the welding line on the strength and appearance of the product should be considered.

12. For a multi-cavity plastic mould, reasonable, symmetry and compact positioning is able to prevent the eccentric load, reduce the mold base dimension and the tonnage of the molding machine.

13. For a multiple products mould which is also called family mold, the size of the gate must be adjusted according to the plastic parts dimension to ensure that each product is filled simultaneously.

14. For the complicate product, it's necessary to make mold-flow analysis to help design a good runner system and gate position.

Design standard for Sprue:

1.Injection molding machine nozzle and sprue matching

The spherical surface SR of the mold sprue should be 1-2MM larger than the nozzle SR of the injection molding machine. The SR of the nozzle can be found in the specifications of the injection molding machine.

Attention: When designing the mold, check the length of the nozzle of the molding machine that can be inserted into the mold. Should make proposal if have to use the extended nozzle.

2.Sprue diameter ⌀D setting

The sprue D should be 0.5mm larger than the the nozzle of the injection molding machine.

3.To shorten the sprue, we have to:

A.For two plate mould, sprue should be sunk in to the A plate (except for special customer requirements).

B.For three plate mould, big spue bush is must if the sprue length is 25mm or more.

C.Plastic parts with appearance requirements and other special requirements use hot sprue.

Design standard for Runner:

1.Type of runner.

A.Round runner.

B.U shape runner.

2.D series: 2 2.5 3 3.5 4 4.5 5 6 7 8 (10 12 reference use)

3.The runner diameter setting

For PE, PA, the diameter can be small. For PC, PMMA, the diameter value can be a large value.

Estimation diameter according to experience

4.Precautions

A.In the U-shaped runner, the size of the runner can be changed by

adjusting the H value.

B.Use round runner whenever possible

C.The runner must be thicker than the section of the subordinate

runner (see table below), if the secondary runner increases,

D1 diameter can be reduced according to the actual situation.

Design principles for common gates:

The form, position, size and number of nozzles should fully meet the requirements of mold processing and parts production.

1.Direct gate

1. Low pressure loss, easy to fill
2. The pressure at the gate is large, which will cause deformation.
3. It is difficult to remove the nozzle
4. Common gate
5. Easy mold processing
6. Correction is easy
7. Thin and long barrel products should not be used.
8. It is necessary to take care that whether the subsequent processing of the nozzle is convenient and whether the residue after processing will affect the appearance and function of the product.
9. Pin point gate
10. Flexible to select the gate location.
11. Small residual stress near the gate
12. After the mold is opened, the gate can be pulled off by itself. The traces left on the plastic part are not obvious, and the appearance of the surface of the plastic part is not affected.
13. The flow rate of the molten plastic flow through the gate is increased, and the frictional force acts to increase the temperature of the plastic stream. In this way, a plastic part with a clear shape and a glossy surface can be obtained.
14. Injection pressure loss is large, which is not good for plastic molding.
15. The mold structure is more complicated, and the double parting line mold (three plate mold) is generally used to remove the sprue.
16. Because the high flow velocity near the gate, the molecules are highly oriented, and local stress is increased, which may cause cracking. Therefore, without affecting the function of the plastic part, increase the wall thickness of the plastic part opposite the gate.

H.Warpage wil occur when a large plastic part adopts a point gate, so multiple point gates should be used at

the same time.

4. Sub-gate
5. Gate can be located inside or outside of the plastic product, the gate is usually located at the bone position of the injection molded product, the gate is concealed and does not affect the appearance of the injection molded part.
6. Small gate mark.
7. Gate is cut automatically.
8. There is a problem of large pressure loss.
9. Large flow resistance.
10. Fan gate
11. Good liquidity.
12. Can be evenly filled to prevent deformation of plastic parts.
13. The plastic parts look good.
14. Gate is not easy separate.
15. Large gate residue
16. Suitable for large and thin-walled plastic parts.

Slug well design

The location of the slug well is generally designed at the end of the sprue and runner.

That is, the first place where the melt plastic arrives, and venting is must added.

The design of the slug well varies depending on the different gate type.

Ejection of sprue

Normally, designer should have a thorough understanding of material properties, choose the most suitable solution.

The Principles of parting line plastic injection molding Design

1. The part with coaxiality requirement should be formed on the core side. If it is formed in the cavity and core side, it will be difficult to ensure the coaxiality due to the inaccurate clamping.

2. When selecting the parting surface, the dimension difference between the ends of the plastic part due to the draft angle should be reduced. The parting surface should be selected as much as possible without affecting the appearance of the plastic part and is able to meet the requirement of appearance. The split line and miss-match shall be submitted to the customer for confirmation;

3. The distance between the plates: the determination of the parting line should ensure that the mould cavity and core opening strokes are the shortest;

4. Should avoid the core pulling mechanism as much as possible, if it is impossible to avoid the core pulling, the pulling distance should be as short as possible, and try to make the slider all in core side;

5. Since the locking force is small when the inclined slider is closed, for a large plastic part with a large projection area, the parting line of the large projection area can be placed on the main plane after the cavity and core clamped, and the smaller projected area as the lateral parting surface, otherwise the locking mechanism of the inclined slider must be very large, otherwise, the burr is occurred due to non-tight lock.

6. The determination of the parting surface does not affect the normal opening of the injection gate system, especially the two plate mold with the multi-cavity parting surface.

7. In order to help the venting of the mold, the parting surface is as close as possible to the end of the plastic material stream.

8. The overall structure of the injection mould should be simplified, the number of parting line in mouldis minimized, and a straight parting line is used as much as possible. Should also consider whether the mold is easy to machining and process, easy to take out the finished plastic part, the parting surface should be selected as much as possible on the ridge of the plastic part.

9. Convenient installation of metal inserts.

10. Keep the product in the core side as much as possible and make sure there is enough position.

11. Sharp corners should be avoided in the parting line, as sharp corners will affect the life of the plastic injection mould. Therefore, parting line in plastic designshould check very carefully. If it cannot be avoided, send a proposal to the customer whether the product can be modified.

Types of Worm Gear Slewing Drive

According to the form of the variable speed transmission of the slewing drive, it can be divided into a tooth type slewing drive and a worm drive slewing gear, inheriting the respective characteristics of the slewing gear drive and the worm gear drive, and the two slewing drives can be adapted to medium and high speed and low speed applications respectively. In terms of carrying capacity, the worm-and-worm type performs better than the gear type, and its load carrying capacity, deformation resistance and transmission rigidity are further improved when using an envelope worm drive, but the efficiency of the worm-gear type slewing drive is Inferior to the toothed rotary drive. According to the openness of the slewing drive transmission mechanism, the slewing drive can be divided into open type and closed type. Generally, the open structure is mostly used in applications where the environment is too harsh, the maintenance and maintenance cycle is short, and the open structure is more convenient for the machine. Inspection, maintenance and maintenance are also easier to replace. Closed structures provide a longer maintenance lifecycle where environmental conditions do not change much and are below the level of environmental pollution below medium.
