Injection molding is a plastic molding process, by injecting heated and melted plastic material into a mold, after cooling and curing, to form a plastic product with a certain shape, size and function.
Injection molding is usually applied to the production of high-volume, high-precision, complex-shaped plastic products, such as electronic product shells, automotive parts, home appliance parts, plastic boxes and so on. The process generally includes mold design, plastic material processing, injection molding, parts processing, quality inspection, etc., requiring sophisticated equipment and technical support. The shape and size of these products depend directly on the size of the mold. Injection molding has the main advantages of mature technology, fast molding, flexible production and so on.
Injection molding process has the advantages of high production efficiency, low production cost, exquisite appearance of products, stable performance, and so on, so it has been widely used in the industrial field. At the same time, with the continuous development of science and technology, injection molding technology is also constantly updated and upgraded, for the production of plastic products to bring more possibilities and development space.
The main types of injection molding
1, rubber injection molding: rubber injection molding is a rubber material directly from the barrel into the model vulcanization of the production method. The advantages of rubber injection molding: although intermittent operation, but the molding cycle is short, high production efficiency eliminates the embryo preparation process, less labor-intensive, excellent product quality.
2, plastic injection molding: plastic injection molding is a method of plastic products, the use of molten plastic pressure into the plastic products mold, cooling and molding want a variety of plastic parts. There are specialized for injection molding machinery injection molding machine. Currently the most commonly used plastics are polyethylene, polypropylene, ABS, PA, polystyrene and so on.
3, molding injection molding: the resulting shape is often the final product, in the installation or as a final product before the use of no other processing. Many fine details, such as projections, ribs, threads, can be molded in the injection molding one-step operation.
