About plastic mold enterprises, what is plastic molding mold

Plastic mold is a tool that is used in the plastic processing industry to match the plastic molding machine to give plastic products a complete configuration and accurate size. Due to the variety of plastic varieties and processing methods, and the structure of plastic molding machines and plastic products, the types and structures of plastic molds are also diverse.

A combined plastic mold for compression molding, extrusion, injection molding, blow molding and low foaming molding, mainly comprising a die with a variable cavity composed of a die combination substrate, a die assembly and a die combination clamping plate, and a punch with a variable core composed of a punch combination substrate, a punch assembly, a punch combination clamping plate, a cavity truncation assembly and a side section composite plate.

Coordinated changes in mold convex, concave mold and auxiliary molding system. It can process a series of plastic parts of different shapes and sizes. In the plastics processing industry, it is used in conjunction with plastic molding machines to give plastic products a complete configuration and precise dimensional tools.

Due to the variety of plastic varieties and processing methods, and the structure of plastic molding machines and plastic products, the types and structures of plastic molds are also diverse.

With the rapid development of the plastics industry and the continuous improvement of the strength of general and engineering plastics, the application range of plastic products is also expanding, and the amount of plastic products is also rising.

A plastic mold is a tool for producing plastic products, which is composed of several groups of parts, and this combination has a molding mold cavity. During injection molding, the mold is clamped on the injection molding machine and the molten plastic is injected into the mold cavity.

And in the cavity cooling and shaping, then the upper and lower molds are separated, the products are ejected from the mold cavity and leave the mold through the ejection system, and finally the mold is closed for the next injection molding, and the whole injection molding process is carried out in cycles.

Generally, the plastic mold is composed of two parts: the moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the moving mold and the fixed mold are closed to form a gating system and cavity, and the moving mold and the fixed mold are separated during the mold opening so that the plastic products can be removed.

The most important factors of mold material are thermal strength and thermal stability, commonly used mold material: working temperature forming material mold material.

SKD61 S136 8407 VIKING NAK80 The most important thing depends on what kind of plastic mold you make.

The plastic mold injection molding processing manufacturer is Jiaxing Hanqing injection plastic molding processing factory. Injection molds can form a plurality of complex structure, precise size, intrinsic plastic parts at one time, so it has been widely used in the production of plastic products, design and manufacturing, geometry and structural size design is reasonable, directly affecting the rheological properties and filling effect of polymer melt in the mold channel.

Plastic mold injection molding featuresFirst of all, from the preliminary design, experienced practitioners are required, most of whom need to rely on the knowledge and experience of mold designers, such as jet flow, warpage deformation, weld marks and underinjection and other phenomena, which are inseparable from the design of the gating system.

Control the mold temperature is to heat the mold to the working temperature, the second is to keep the mold temperature constant at the working temperature, the mold production batch is small, generally belongs to the production of a single piece, but the mold needs a lot of standard parts, large to the mold base, small to the thimble, these can not and cannot be completed by only one manufacturer alone, and the manufacturing process is complex, and the use of ordinary equipment and CNC equipment is extremely uneven.

I don't know which process you are referring to, different processes and costs choose different materials and processing methods!

Generally, the materials used in plastic molding molds are metal, fiberglass, gypsum, wood, etc., and then processed into the shape you need through a certain method (different processes have different requirements for mold processes).

You're talking about injection molds, and there are manufacturers that specialize in producing abrasives, depending on what you do.
