Plastic injection molding refers to a processing technology that heats plastic parts to a molten state, injects the molten plastic into a mold through a high-pressure injection machine, and then cools and solidifies to form plastic products.
Plastic injection molding process
Preparation of raw materials: Select appropriate plastic resin and mix it with additives in a certain proportion.
Melting: Add the plastic raw materials to the screw of the injection machine to melt, and then inject the molten plastic into the mold through high pressure.
Cooling: After the plastic injected into the mold solidifies, the finished product is taken out and cooled to form a stable shape.
Advantages of plastic injection molding
High precision and efficient
Plastic injection molding technology enables efficient, high-precision production. Through injection molding technology, large quantities of products can be produced in a short time. At the same time, since injection molding is completed in a closed mold, the accuracy and dimensional stability of the finished product can be guaranteed.
High productivity
The production efficiency of plastic injection molding technology is very high. Injection molding machines can achieve continuous production and can perform automated production, reducing manual intervention. In some mass production situations, injection molding technology can achieve higher production efficiency than other molding technologies.
Material diversity
Plastic injection molding service can be applied to the molding of a variety of materials, including polypropylene, polystyrene, polycarbonate and other materials. Optimization of product performance can be achieved through different material selections and adjustments.
Molding process
The molding process of plastic injection molding technology is relatively simple. During molding, the plastic material only needs to be melted, injected, and cooled in three steps to complete. Since the size and shape of the injection molding mold can be designed freely, the production of products of different shapes can be completed in a shorter time.
