This is too easy to understand because LED is expensive! The 100-inch Sony TV has already sold for 500,000 yuan! At present, with the increase in LED size, the price has doubled. If the LED is put into cinemas and made into a length of more than 10 meters, the cost is unimaginable. If the LED screen is damaged, artificially damaged, etc., these will cost an arm and a leg.

Using a projector is usually called watching a movie, will using an LED screen watching TV. What if consumers complain about paying for movie tickets but watching TV?

In fact, it mainly attributes to cost, portability, and image quality. The fineness of images displayed on LED screens cannot equal with that of projectors, especially when digital projectors now have technically up to 2048*1080p resolution and can easily achieve high-definition effects.

At present, projection is the most eye-friendly one. Objects in nature, which we usually see, do not emit light themselves. Only when natural light is reflected in the objects can we see them. If it is dark, nothing is visible. LED, working on self-illumination, is anti-human and is not good for eyes. Projection is to project light onto screen cloth. When we look at projection cloth, it does not emit light. Just like looking at objects in nature, it can give people a more real feeling. The reason why reading on kindle will not make eyes easily tired is that ink screen is not a self-luminous but a reflective screen. In the same way, LED cinema does more harm than benefit. Blinding your eyes in order to watch a movie, it’s more than worth it!

Theater T700 projector is 1080p in native resolution

Resolution: For small-pitch LED, higher pixels per inch means that the difficulty of stability design increases geometrically, pixel pitch decreases by 50%, and backplane density increases by 4 times, so the resolution of small-pitch LED is difficult to further improve. At present, cinemas have basically reached 2K level, so small spacing LED still cannot meet the standards of cinemas in terms of picture definition.

At the same time, in addition to poor heat dissipation, LED display screens are also prone to some problems, such as "bad spots". At present, most of the LED screens seen have bad spots more or less. If maintenance is not carried out in time, diffusion will be formed, which will affect other normal bright spots and eventually lead to an abnormal display of some or all of the display screens. Compared with the easy-to-care screen, the maintenance cost of the LED screen cannot be ignored.

In fact, that piece of cloth in the cinema is quite expensive, so is the projector. Items like 3D, laser, etc. are quite expensive. In fact, many LED screens can be assembled on the spot, and the size is not limited. Pieces of LED screens are assembled one by one, and the cost is not too high. Why are they not used in cinemas, mainly because the existing machines in cinemas still work well? New machines will increase costs. The other reasons are inertia and conformity.

Sheet metal processing or sheet metal fabrication includes: folding, shearing, punching, welding, riveting, splicing and other processes. In general, the process of forming a sheet by hand or mechanical is called sheet metal processing. Sheet metal processing is to cut and bend metal materials into various shapes and their thicknesses can vary significantly. According to the materials, sheet metal fabrication can be divided into several types, including aluminum sheet metal fabrication, stainless steel fabrication and brass fabrication.

Sheet metal process:

Sheet metal processing drawing design -> Laser processing or (CNC stamping) -> Bending -> Welding Molding -> Electrostatic powder spraying or (liquid paint) -> Packaging and shipping.

1. Drawing design:

In general, the customer provide drawings or samples, then our engineers perform the measurement, design, and development, and form the machining decomposition map and assembly drawing to the production department for processing.

2. Laser processing:

It has a large laser cutting machine, it can be cut by laser cutting  such as carbon steel, stainless steel, etc material. After the workpiece is processed, the section is neat, smooth and beautiful, and the size is accurate. It has advantages for the workpiece with arc. CNC stamping can not replace the processing method.

3. CNC stamping:

With imported turret CNC punching machine, CNC punching is mainly for the thickness of product processing materials, generally suitable for materials below 2.5mm. Sheet metal processing workpieces have more holes or need to open special molds to process the workpiece. CNC punching has a certain cost advantage.

4. Bend:

After the workpiece is cut, if most of them need to be bent and formed, the CNC bending machine not only has a fast speed, but also the workpiece is processed more accurately.

5. Welding molding:

The workpiece needs to be assembled and formed after cutting the material, and the assembly method is various. Some are directly formed by non-welding processes such as screws and riveting. Generally, the mechanical casing is made of welding, and the company adopts argon arc welding, bump welding, carbon dioxide welding, etc., we will polished them after welding, so that the workpiece is relatively firm and beautiful.

6. Electrostatic powder spray:

Electrostatic powder spraying is mainly for carbon steel workpieces. In the process, oil removal and derusting, surface cleaning, phosphating, electrostatic powder spraying and high temperature baking are generally carried out. After processing, the surface of the workpiece is beautiful, it will not rust within a few years, and the cost is low.

Liquid paint: This process differs from electrostatic powder spray. It is mainly used for large workpieces. It is convenient and low-cost to use liquid paint when it cannot be handled. The liquid paint is divided into two steps, and the primer is applied to the paint after the workpiece is processed.

7. Packaging and shipping:

100% inspection before packaging and inspection data.

Advantages of Sheet Metal

Sheet metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, large-scale mass production performance, etc. It has been widely used in the fields of electronics, telecommunications, automotive industry, medical equipment and so on. For example, in computer cases, mobile phones, and MP3s, sheet metal is an essential part.

What is CNC Machining?

CNC machine offered by cnc machining companies in china is commonly used in manufacturing and industrial production. But exactly what is CNC machining?

CNC (Computer Numerical Control) machining is a kind of subtractive manufacturing process. In CNC manufacturing, the software control system issues commands to make the tool meet the required movements. In this process,various precision tools are used to remove layers of raw materials and make parts or products. Therefore, it can also be called cnc precision machining.

Types of CNC Machining

Three-axis CNC machining

The 3-axis machining is performed by straight lines to the axes X, Y, and Z. 

Machining features: the cutting tool orientation remains constant during movement along the entire cutting path. 

The 3-axis machining center has the advantages of high precision and high efficiency. It is commonly used to machine general parts, but it is more troublesome when machining complex workpieces, which may cause the workpiece to fail. Therefore, multi-axis simultaneous machining is the first choice when machining more complex workpieces.

Five-axis CNC machining

Five-axis machining is the use of CNC to move parts or cutting tools on five different axes simultaneously, which can process very complex parts. 

The remarkable feature of the five-axis linkage CNC machine tool is that it can complete the surface machining, and no special fixture is needed during machining, which greatly reduces the number of clamping and improves the machining accuracy, quality and efficiency. The five-axis machining center has unparalleled advantages in the processing of complex workpieces.

CNC milling

CNC milling machine processing is based on the technical requirements of the shape, accuracy, size and surface roughness of the workpiece to determine the processing technology and processing parameters. Program the machining program into the controller and send the command to the servo. CNC milling machines can process parts with particularly complex contours or difficult to control dimensions, such as mold parts and housing parts. It has the advantages of strong adaptability, high processing precision, stable processing quality and high efficiency.

CNC turning

CNC turning is one of the most used machining methods in CNC machining. During CNC turning, the workpiece makes a rotary motion, and the tool moves in a straight line or a curve. While the tool tip moves relative to the workpiece, a certain workpiece material is removed to form a corresponding workpiece surface.

 

Applications of CNC Machining

Electronic Products

The full metal casing of 3C products is basically processed by CNC machine tools CNC. CNC has become a must-have for 3C enclosure manufacturers due to its high efficiency, high precision and stable processing quality.

Automobile

CNC machining plays an important role in the automotive industry. It can be said that most automotive parts are processed by CNC machining.
