Injection molding processing means that the client provides raw materials and molds, and the injection molding manufacturer manufactures injection molded products according to the client's requirements and charges processing fees.

Injection molding, also known as injection molding, is a molding method for injection molds. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, diverse colors, simple to large shapes, large to small sizes, accurate product sizes, easy product replacement, and complex shapes. Parts and injection molding are suitable for mass production and molding and processing of complex shapes.

Injection molding is an industry with a wide range of knowledge and strong technical and practical capabilities. In the injection molding production process, plastic raw materials, carbon powder, nozzles, molds, injection molding machines, peripheral equipment, fixtures, sprayers, various auxiliary materials and packaging materials are used. These have brought great results to the management of the injection molding workshop. Compared with other industries or departments, there is a certain degree of difficulty, and the requirements of management personnel of injection molding workshops at all levels are higher.

Although the mold structure may be different due to the types and properties of plastics, the shape and structure of plastic products, and the type of injection molding machine, the basic structure is the same. The mold is mainly composed of a pouring system, a temperature control system, molded parts and structural parts. The gating system and molded parts are in direct contact with the plastic and vary with the plastic and the product. They are the most complex and most variable parts in the mold and require the highest precision and highest precision of the parts.

Injection molding production requires 24 hours of continuous operation, which is usually a two-stage three-stage or three-stage working mode. There are many jobs and divisions of labor in the workshop of the injection molding workshop, which have different skill requirements for different positions. In order to make the production and operation of the injection molding workshop go smoothly, it is necessary to manage the personnel, materials, equipment and tools involved in each link and location, which mainly include: raw material room, waste room, batching room, production site, post-processing area, tools The operation and coordination management of various fields such as room, semi-finished product area, office and so on.
