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.

1. Process analysis of plastic products.

Before the die design, the designer should fully analyze whether plastic products conform to the principle of injection molding. It is necessary to consult with the designer carefully and reach a consensus. It includes the necessary discussion of the geometric shape, dimensional accuracy and appearance requirements of the products, and avoids the unnecessary complications in injection mold building as far as possible.

2. Design of die structure.

A set of high-quality die not only needs good processing equipment and skilled injection mold builder but also a very important factor is to have good die design, especially for complex dies, the quality of die design accounts for more than 80% of the quality of the die. Excellent die design is: on the premise of meeting the customer's requirements, the processing cost is low, the processing difficulty is small, and the processing time is short.

3. Determining die materials and selecting standard parts.

In the selection of die materials, besides the accuracy and quality of products, the correct selection should be made according to the actual ability of processing and heat treatment in the dying factory. In addition, in order to shorten the manufacturing cycle, the existing standard parts should be used as much as possible.

4. Part processing and die assembly.

In addition to giving the best structure and reasonable tolerance coordination in the design of the precision of the die, parts processing and die assembly is very important. Therefore, the selection of processing accuracy and methods plays an absolute leading role in die manufacturing.

Therefore, in order to reduce injection mold building error, first of all, the processing accuracy should be improved. With the use of CNC machine tools, this problem has been well controlled. In addition, in order to prevent the errors caused by the wear and deformation of the die, quenching treatment should be applied to the key parts such as the cavity and core of the die when the processing precision is high and the output of the product is high. In order to save material and facilitate processing and heat treatment, the mosaic structure should be adopted in die design.

In order to solve the errors caused by uneven shrinkage and inconsistency between pre-contraction and actual contraction, the product tolerance of 1/3 is generally selected as injection mold building tolerance in injection mold building. The purpose is to leave greater room for adjustment in the later forming process, so as to solve the errors caused by the forming process.

5, model test.

A set of molds starts from design to assembly, only 70% to 80% of the whole manufacturing process is completed. For the errors caused by the inconsistency between pre-contraction and actual contraction, the smoothness of demoulding and the cooling effect, especially the influence of gate size, position, and shape on the accuracy and appearance of products, it must be checked by test mold. Therefore, die testing is an indispensable step to check whether the die is qualified or not and to select the best forming process.

Hanking's successes are ensured by our management capability, technical knowledge, advanced plastic tooling equipment and professional injection molding services. We are pursuing better quality and technical capability to meet the demands of increasing mold making markets.

At present, China has become the world's largest mold manufacturing country. According to customs statistics, the total import and export volume of China's molds in 2017 was 7541.8243 million US dollars, an increase of 11.01% over the previous year. Among them, imports amounted to $205139.38, an increase of 2.43% over the previous year; exports amounted to $549,043.05, an increase of 14.61% over the previous year.

At the same time, with the output growth of new energy automobiles, household appliances, and other products, the demand for die steel is increasing. The growth of large-scale precision die also drives the demand for die steel and puts forward higher requirements for the quality, dimensional accuracy and stability of die steel.

In addition, the level of standard parts of die and mould is constantly improving, and its application is increasingly widespread, which puts forward higher requirements for product quality, variety specifications, and delivery cycle of the die and mould steel. As an important base of mould manufacturing in China, the output of mould increases year by year, the consumption of mould steel keeps rising, and the consumption of high-quality mould steel increases faster.

The 9th Global Precision Mould Conference on Material and Accessories Applications will be held accordingly. Combining the keynote report with the symposium, the conference will build an interactive service platform for global precision mould manufacturing enterprises, die steel manufacturing enterprises and die parts enterprises. It is hoped that die steel manufacturers will develop high-quality die steels with high precision, high toughness, and corrosion resistance according to the development trend of domestic die manufacturing enterprises and the market demand, so as to make the domestic die steels reach the advanced level of global precision mould as soon as possible.

HanKing Mould supports customized plastic molds, metal stamping molds, plastic parts processing, medical instrument parts mould, household appliance parts mould, auto parts mould, tableware mould etc. We are committed to contributing to the global precision mould industry.

(1) Planning

In order to improve timeliness, project, and parts should be planned in detail. Planning at the level of the injection project and each individual part is the key to achieve timeliness. The planning system can plan all process steps in detail and provide a capacity overview so that the relevant personnel can grasp the demand for each technology and the corresponding available capacity. In order to improve the timeliness, there should be further algorithms in the planning system to find the optimal sequence of production operations. Based on tablet or smartphone applications, management can track the status of key projects at any time.

(2) Automation

The second key area of action is automation, where automation solutions help to improve equipment utilization. Observing the proportion of manufacturing cost in the whole process chain in Figure 9, it is easy to see the benefits of automation solutions adopted by German injection molding enterprises. In Germany, only 34% of the cost of injection molding is spent on manufacturing, while 52% of the cost of injection moulding company China is allocated to manufacturing. The main reason is that German injection molding enterprises are highly automated in milling and EDM. Automation is one of the key areas in which German injection molding enterprises have made great progress in the past 10 years.

(3) Digitalization and visualization

For many injection moulding companies China, quality remains a challenge. In order to reduce quality errors, it is important to identify errors early in the order completion process. Many errors are found in the late stage of the process chain, such as in the test, which will greatly increase the cost and time needed to correct the errors.

(4) Tool management

In order to further improve the processing efficiency, tool management with a clear structure is the key factor to achieve high-efficiency manufacturing. The unreasonable tool management results in more preparation time for injection moulding company China in the processing process. By centralized management of tool data and focusing on a certain number of standard tools, production efficiency can be effectively improved. Data matrix code (DMC) can be used to mark the tool, and the central tool management system can be used to register, manage and call the tool data. In this way, the central tool management system can record the tool wear condition, and invoke the actual data of the tool in the programming and processing process, so as to improve the machining accuracy. Meanwhile, structured tool management can save time and space, and tool standardization can reduce errors in workpiece preparation and facilitate clearer arrangement of tools and their accessories.

Established in the year of 1996, HanKingtec. starts the business in mould engineering, after years of development, we have become a one-stop total plastic injection molding solution provider which including mold making, injection molding, second process and final assembly.

Injection molding parts are the basic technological equipment of industrial production. Formulas have been obtained. In electronic, automobile, television, electrical appliances, instruments, instruments, household appliances and telecommunications products, 60% and 80% of the parts are molded by injection molding parts. The injection molding parts have high precision, complexity, consistency, high productivity, and low energy consumption, which are incomparable with other manufacturing methods. It is also a "benefit amplifier". The value of the final product produced by injection molding parts is often tens or hundreds of times the value of injection molding parts themselves. Specifically, taking the popularization of integrated manufacturing units and technologies for injection molded parts as an example, in recent years, in addition to the functions of automatic feeding, stamping, lamination measurement, thickness grouping, iron core combination and product output, hinge assembly and connection, injection molded parts have also emerged complex motion structure, in-mold heating, forging, local thermal (tissue) control, in-mold welding, tapping, local injection, In-die cutting, in-die testing and other process combination. For example, the application of 3D printing to produce an injection molding cavity is a new trend in the development of injection molding parts. The technology of metal material addition and material reduction combined manufacturing is an important direction in the field of 3D printing nowadays. High precision manufacturing of complex metal parts is realized by 3D incremental forming and high-speed milling. At present, the top three applications are industrial machinery, aerospace, and automobile, accounting for 20.0%, 16.6% and 13.8% of the market share respectively.

Injection-molded parts China industry developed late. The modern injection parts industry did not start until the end of the 1970s. However, after many years of efforts, injection molded parts China manufacturing industry has established a research and development institution including injection parts technology and injection parts by introducing mature design and manufacturing technology and independent innovation from developed countries and regions. The industrial system of injection molding parts, including the production and supply system, has made considerable progress in scale and technical level of injection molding parts industry.

Since 2012, the number of patent applications related to injection molded parts China has steadily increased. In 2017, the number of patents filed reached 22,872, exceeding 20,000 for the first time, a record high. In 2018, the number of patents filed decreased, but still exceeded 17,146, to 17,146.

What is insert hanking mold? What is hanking mould technology?

Insert molding solutions refers to a hanking moulding process in which an integrated product is made by inserting a pre-prepared metal material insert into a hanking mould and then injecting the plastic resin, and the molten material is bonded to the insert, cooled and solidified.

Insert molding features are as follows:

The moldability and flexibility of plastic resins, as well as the rigidity, strength and heat resistance of metal parts, create complex and sophisticated metal-plastic integrated products.

In particular, the electrical product made by insert molding, together with the insulation of the resin and the electrical conductivity of the metal, can meet the basic functions of electrical products.

The pre-formed combination of multiple inserts makes the subsequent product unit combination engineering more rational.

Inserts are not limited to metal, but also cloth, paper, wire, plastic, glass, wood, wire, electrical parts and so on.

For the rigid molded product and the curved elastic molded product on the rubber gasket plate, the parts by insert molding can eliminate the complicated operation of installing the sealing ring, and help the subsequent process automation.

Compare to the press-in molding, the metal insert gap can be designed to be narrower, and the reliability of the composite product molding is higher as the plastic resin is molten to wrapped with the metal insert.

Selecting the appropriate plastic resin and injection molding conditions, even for products that are easily deformed or broken (such as glass, coils, electrical parts, etc.), can be sealed and fixed by insert molding with plastic resin.

Designed the appropriate mould construction, the insert can also be completely enclosed in the plastic resin.

By the combination of a vertical injection molding machine and a robot, insert arranging mechanism, most of the insert molding projects can be automated.

The product with a hollow groove also can be made by insert molding after the core hold treatment.

Automatic insert molding system design points:

The shrinkage rate of metal insert molding is not uniform, and the limit test of the shape and dimensional accuracy of the important areas should be done in advance.

The metal insert has the possibility of deformation and displacement during the injection process, and the designer should be fully considered about mould construction to help stabilize the metal insert. For products whose insert shape cannot be changed, prior testing is indispensable.

Where the arrangement of the metal inserts is separated and the conveyor is used, the contact between the metal inserts and the plastic and the vibrating balls may cause slight damage to the surface of the insert, which may affect the quality of the product, the quality tolerance limit should be confirmed in advance.

The zigzag shape, the amount of warpage, the difference in material thickness, the difference in diameter, and the difference in thickness due to metal plating processing of the metal insert due to the press working should be determined in advance. Carried out the design of the automation device and the design of the mould structure on this basis.

Mould gate position, molding cycle time, etc., which are the key points of the mould structure, are solved as much as possible or have corresponding improvement solutions.

Industrial hanking moulding parts are referred to the plastic parts of industrial products, hanking mould preferred to think of it as non-consumer products.

Nowadays, the demand for consumer products is oversupplied, and the demand for industrial precision molded products inc is increasing. This is because many parts of the equipment in the past were made of metal. With the development of the plastics industry, more and more industrial product parts are trying plasticization. Metal parts have higher density, greater strength, and thermal and electrical conductivity. However, plastic industrial parts have advantages in mechanical shock absorption, thermal expansion, elongation at break, and toughness. And the properties of plastics can be greatly transformed by the addition of fillers, reinforcing materials and modified materials, engineering plastics perform better in this respect. Use plastic to produce parts that are not necessary for high strength can reduce the weight of equipment, simplify the structure and save costs, this is why industrial molding parts of HanKing Mould Enginering Ltd. are becoming more and more common.

Industrial injection molded parts china range from small plastic gears to large industrial equipment plastic enclosures. The design of the mold is very complicated work, the plastic part structure, the different plastic resin, required life cycle, etc. many factors determine the mold construction.

Designers of Hankingtec must master the properties of different plastics and mould steel, and consider the temperature change, pressure change, steel abrasion during the production process, designed qualified mould.

If the mould structure of hanking mold is unreasonable, even the most excellent operator can not get good plastic parts. The design defects of hanking cannot be solved by the defects in the production process. Only when all the factors are considered in the design of the hanking mould technology, the shenzhen hanking mould quality and stability of the mass production can be guaranteed.

As one of the most professional chinese plastic injection molding companies, HanKing Mould serves for globally Automotive & Vehicle products customers, more than 10 years of experience of hankingtec and hanking mould technology enabling the HanKing Mould Enginering Ltd. to provide customers the fast development time and stable quality to ensure the new project running well. Hanking mold engineer will analysis the filling to obtain the best gate position the best flowing regime, and design the best cooling channel to ensure the minimum wrapping deformation and hanking moulding has a very good injection operator to help set the best injection parameter to avoid any development time waste and improving the molding parameter reliability.

Shenzhen HanKing Mould is very experienced in small and medium-sized automotive mould, in the past years, the types of products we involved were included fuse and fuse box, connector, switch, relay, sensors, actuators, terminal, valve, handle and other body accessories.

In the development of the automotive industry, the proportion of plastic parts in automotive parts is very large, and the demand for plastic parts is increasing day by day because plastics have the advantages of beautiful appearance, lightweight and easy processing. Most plastics have a specific gravity of 0.9 to 1.6, and the proportion of glass fiber reinforced composites will not exceed 2.0, while A3 steel is 7.6, brass is 8.4, and aluminum is 2.7. The use of plastic can reduce the weight of parts by about 40%, and the cost can be greatly reduced, which makes plastic the preferred material for automotive light-weighting. Plastic is easy to molding parts with complex shapes. According to the plastic composition of the plastic, by adding different fillers, plasticizers and hardeners to produce the desired properties of the plastic, changing the mechanical strength and processing properties of the material to meet the requirements of different parts of the car. The plastic consumption of each auto part accounts for 20% of the total vehicle materials and may reach 35% in the future. When the auto company develops a new car, it needs to use hundreds of sets of plastic injection molds, which requires the quality assurance of plastic parts in production, and the quality of plastic parts is determined by the mold.

Which parts of the car are commonly used in plastic?

Bumper, the instrument panel accessories, inlet grille, fender, radiator grille, trim panel, engine parts, Water tank accessories, air conditioning accessories, air filter accessories, various kettles, seat accessories, floor panel accessories, roof panel accessories, bar accessories, steering wheel accessories, door trims, rearview mirrors and various fastener, front and rear lamp, etc.
