What Is The Injection Molding?
Injection molding is an important method in the molding process of high-polymer materials.
It is characterized by short molding cycle time, high production efficiency, complex shape and precision size products, used in a wide range of products, and it is easy to achieve fully automated production.
It is widely used in almost all thermoplastics, and a variety of thermosetting plastics can be injection molded, and Of course, rubber products can also be injected.
Except for a few thermoplastics, almost all thermoplastics can be molded by plastic injection molding services.
With the development of the petroleum industry, plastic injection molding technology has developed greatly, especially with the emergence of plastics as structural engineering materials.
The application of injection molding products has been expanded to various fields of the national economy, injection molding products account for about 30% of the total number of plastic products.
Plastics Injection molding is injecting the granular or powdered plastics from the hopper into the barrel of the injection machine after heating and melting plasticized, under the rapid and continuous pressure of the plunger or moving screw of the injection machine is compressed and moved forward through the nozzle at the front of the barrel, with high pressure and very fast speed into the closed mold, after cooling (thermoplastic) or heating (thermosetting) curing, open the mold to get the product.
Plastic Injection molding Services is an intermittent production process that can produce plastic products of various shapes and sizes, except for very large profiles such as tubes, rods, and plates, which this method cannot produce.
It is commonly used not only for the direct resin injection but also for molding composite materials, reinforced plastics, and foam injection molding. It can be combined with other processes, such as injection-blow molding in conjunction with blowing.
