Brief analysis of injection molding machine size and production process

The size of injection molding machine should not only meet the requirements of use and installation, but also consider the mold manufacturing, equipment performance and raw material flow. Strictly control the factors affecting the accuracy of injection parts, including mold manufacturing accuracy, plastic composition and process conditions.

The surface roughness of injection molding is determined by the surface roughness of the mold, so the surface roughness of the mold is one level lower than that of the product. The requirements are met by grinding and polishing. The cooling shrinkage phenomenon of the injection parts in the mold cavity will lead to the difficulty of disassembly of the injection parts, It should also be considered that the inner and outer surfaces parallel to the stripping direction have enough stripping slope.

Injection molding is the molding method of injection mold. The advantages of injection molding are fast production speed, high efficiency, automatic operation, various colors, size from large to small, easy to change product size and complex shape. Parts and injection molding are usually used for mass production of complex shapes.

Injection molding is an industry with strong technology and practical skills. In the process of injection molding, the use of plastic raw materials, toners, nozzles, molds, injection molding machines, peripherals, fixtures, sprayers, various auxiliary materials and packaging materials, to the injection workshop management has brought great results. Compared with other industries or departments, there is a certain degree of difficulty, and the requirements for managers at all levels of injection molding workshop are also higher.

Although the structure of the mold may be different due to the type and performance of plastics, the shape and structure of plastic products and the type of injection molding machine, the basic structure of the mold is the same. The mold is mainly composed of gating system, temperature control system, mold parts and structural parts. Gating system and molded parts are in direct contact with plastics, which is different from plastics and products. They are more complex and changeable in the mold, and need high precision parts.

Injection molding requires 24 hours of continuous work, usually two or three stages of work. Injection molding workshop has a variety of work and division of labor, different positions have different skills requirements. In order to make the production and operation of the injection workshop go smoothly, it is necessary to operate and coordinate the management of the personnel, materials, equipment and tools involved in each link, including raw material room, scrap room, dispensing room, production site, post-treatment area, production room, semi-finished product area, office room, etc.
