The size and production process of injection molding

Release time:2019-12-30

     The size of injection molding should not only meet the use and installation requirements, but also consider the processing and manufacturing of the mold, equipment performance and the flow of raw materials. Strictly control the factors that affect the accuracy of injection molding parts, including the manufacturing accuracy of mold, 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, and the requirements are met by grinding and polishing. In order to facilitate the demoulding, it is necessary to design the inner and outer surfaces parallel to the demoulding direction with enough demoulding inclination.

     
        Injection molding is the molding method of injection mold. The advantages of injection molding are fast production speed, high efficiency, automatic operation, various colors, sizes from large to small, convenient size replacement and complex shape. Parts and injection molding are often used in the mass production of complex shapes.

Injection molding is an industry with strong technology and practical ability. In the process of injection molding, plastic raw materials, carbon powder, nozzle, mold, injection molding machine, peripheral equipment, fixtures, sprayers, various auxiliary materials and packaging materials are used. These have brought great achievements to the management of injection workshop. Compared with other industries or departments, there are certain difficulties, and the requirements of injection workshop managers at all levels are higher.

Although the structure of the mold may vary due to the type and performance of the plastic, the shape and structure of the plastic product, and the type of injection molding machine, the basic structure is the same. The mould is mainly composed of pouring system, temperature control system, moulded parts and structural parts. The pouring system and molded parts are in direct contact with the plastic and change with the plastic and the product. They are more complex and changeable parts in the mold, which need high precision parts.

Injection production requires 24 hours of continuous operation, which is usually a two-stage or three-stage mode of operation. There are many kinds of work and division of labor in the injection molding workshop, which have different skill requirements for different posts. In order to make the production and operation of the injection workshop go smoothly, it is necessary to manage the personnel, materials, equipment and tools involved in each link, mainly including the operation and coordination management of raw material room, waste room, batching room, production site, post-processing area, tool room, semi-finished product area, office and other fields.
