Because of its excellent properties that many other materials do not have, plastics are used more and more widely and have a wider range. Compared with other materials, plastics have the following performance characteristics.

1. Light weight

Plastic is a light material with relative density between 0.90-2.2. This property makes plastics suitable for the production of products that require less self weight.

2. Excellent chemical stability

The vast majority of plastics have good corrosion resistance to acid, alkali and other chemicals.

3. Excellent electrical insulation performance

Ordinary plastics are all bad conductors of electricity. Their surface resistance and volume resistance are very large. Plastics are widely used in electronic industry and mechanical industry.

4. The poor thermal conductor has the function of noise reduction and shock absorption

Generally speaking, the thermal conductivity of plastic is relatively low, and its heat insulation, sound insulation and shock resistance are better. After combining the plastic window with the hollow glass, it can be used in residence, office building, ward and hotel.

5. Wide distribution of mechanical strength and high specific strength

According to the mechanical properties of plastics, such as hardness, tensile strength, elongation and impact strength, it has a wide range of distribution and wide choice of use. Because of its small specific gravity and high strength, plastics have high specific strength. (

6. Good formability and low cost

With low melting point, it is easy to obtain parts with complex shape and structure by mold forming. And through the mold for efficient mass production.

7. disadvantages

Easy to burn, less rigid than metal, poor aging resistance, heat resistance, etc.

Injection molding is a kind of plastic molding process, which is to melt the plastic particles in a certain temperature on the injection molding machine, and then inject them into the mold through the injection nozzle, so as to obtain the plastic parts and products that meet the dimensional accuracy, shape and appearance requirements of the design structure. Such as: laptop shell, mobile phone shell, TV shell, auto parts, fruit plate, etc.

Injection molding is realized by injection molding machine and mold. The investment cost of injection molding machine and mould is high. It is a way of mass production with high productivity, low cost and high precision of parts. Especially after the introduction of manipulator automation, the manual operation is saved and the productivity is greatly improved.

It is mainly a kind of molding mold that is most commonly used in the production of thermoplastic parts. The processing equipment corresponding to the plastic injection mold is the plastic injection molding machine. The plastic is first heated and melted in the heating barrel at the bottom of the injection machine, then driven by the screw or plunger of the injection machine, enters the mold cavity through the injection machine nozzle and the mold pouring system, and the plastic is cooled and hardened for molding, Demould to get the product.

Injection mold is a complex system, which includes molding cavity, pouring system, guiding parts, pushing mechanism, temperature regulating system, exhaust system, supporting parts and other parts. The structure of the die varies with the structure, appearance, accuracy and productivity of the product.

Injection molding process is generally applicable to the production of thermoplastics products. The plastic products produced by injection molding process are very extensive. From daily necessities to various complex machinery, electrical appliances, vehicle parts, etc. are molded by injection mold. It is the most widely used processing method in the production of plastic products.

Plastic can be injection molded into parts of various structures and shapes according to the product design requirements, and it is light, very suitable for making the enclosures and internal components of mobile phone, TV, computer, projector, sound, doorbell, home appliance communication and digital products. At the same time, because of its good insulation, it is also widely used in the production of air conditioning, refrigerators, drinking fountains and other household appliances and industrial storage boxes, electrical cabinets, instrument panels and other products with electrical requirements of the shell and parts.

Double shot injection molding refers to the molding process that two different materials are injected into the same set of molds, so as to realize the injection molding of parts formed by two materials. Some two kinds of materials are different in color, some are different in soft and hard, so as to improve the aesthetics and assembly of products.

The generalized double shot injection includes "over molding", which is realized by ordinary injection molding machine and two-time injection. The narrow sense of double shot injection refers to the use of two-color injection molding machine to inject two different kinds of plastics on the same machine to complete the parts, the common one is rotary

Double shot injection molding has been widely used in electronic products, electric tools, medical products, home appliances, toys and almost all plastic fields.

Two color injection molding has been widely used in almost all plastic fields, such as electronic products, electric tools, medical products, home appliances, toys and so on. This is due to the production and molding of two color mold and the development of two color multi-color injection molding machine technology.

1. Complexity of product size, shape and structure. This determines the corresponding structure of the mold, which is directly related to the cost of the mold

2. Product requirements for size and appearance. The precision of the size and the high requirement of the appearance determine the precision of the mould and the processing cost is different

3. The requirement for the number of injection mold cavities is to switch on and off the mold once to produce several products, one or more at a time. Generally, this is not a large product.

4. The expected mold production, which determines the service life of the mold, what kind of material and post-treatment process to be used, is also related to the cost.

5. for the customized export mold, the mold shall be designed and manufactured according to the mold standard of the customer, so as to facilitate the maintenance of the mold by the customer.

Die casting is a kind of metal casting process, which is characterized by applying high pressure to molten metal by using the inner cavity of the die. The mold is usually made of alloy with higher strength. This process is similar to injection molding. Most die castings are iron free, such as zinc, copper, aluminum, magnesium, lead, tin and lead tin alloys and their alloys. Depending on the type of die casting, it is necessary to use cold chamber die casting machine or hot chamber die casting machine.

The cost of casting equipment and mould is very high, so the die casting process is generally only used for mass production of a large number of products. It is relatively easy to manufacture die-casting parts, which generally only needs four main steps, and the single cost increment is very low. Die casting is especially suitable for manufacturing a large number of small and medium-sized castings, so die casting is the most widely used one in various casting processes.

Compared with other casting technology, the surface of die casting is more flat and has higher dimensional consistency.

Usually these metals are die cast

1.Aluminum alloy, die-casting

2.Zinc alloy die casting

3.Die casting of titanium alloy

4.Stainless steel die casting and sintering

One or more function templates, which are used to check the rationality of appearance or structure, are made according to the product appearance drawing or structure drawing after the completion of product design and before the production of production mold.

It is used to check and verify the product design, find defects and problems, and further improve, so as to avoid the huge economic loss caused by leaving the problems behind the mold manufacturing.

Classified according to materials, prototypes includes plastic prototypes, silica gel prototypes and metal prototypes

Accrding to the classification of manufacturing process, prototypes includes manual prototypes and machine-made prototypes. The machine-made includes CNC manufacturing and rapid prototyping.
