Basic principles of injection molding

Injection molding, also known as injection molding, is the molding method of injection mold. The advantages of injection molding processing method are high production speed, high efficiency, automatic operation, color diversity, shape from simple to large, size from large to small, accurate product size, product replacement convenient, complex shape. Parts and injection molding are suitable for mass production and complex shape forming and processing.


Injection molding is a wide range of knowledge, technology and practical ability of the industry. 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 molding workshop. Compared with other industries or departments, there is a certain degree of difficulty, and the requirements of all levels of injection workshop management personnel are higher.


Although the structure of the mold may be different 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 mold is mainly composed of gating system, temperature control system, molded parts and structural parts. The gating system and molded parts are in direct contact with the plastics and vary with the plastics and products.


Injection molding production requires 24 hours of continuous operation, which is usually two-stage, three-stage or three-stage operation mode. There are many jobs and division of labor in the workshop of injection molding workshop, and there are different skill requirements for different positions. 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 and location, including: raw material room, waste room, batching room, production site, post-processing area, tool room, semi-finished product area, office and other fields.
