Plastic injection molding is the most commonly used manufacturing process for manufacturing plastic parts. Plastic injection molding is used to manufacture a variety of products, which vary greatly in size, complexity, and application. The injection molding process requires the use of injection molding machines, raw plastic materials and molds. The plastic is melted in an injection molding machine and then injected into the mold, where it cools and solidifies into the final part.
Plastic injection molding is used to produce thin-walled plastic parts for various applications, the most common of which is plastic housing. The plastic shell is a thin-walled shell, which usually requires many ribs and protrusions inside. These housings are used in a variety of products, including home appliances, consumer electronics, power tools, and car dashboards. Other common thin-walled products include different types of open containers, such as barrels. Plastic injection molding is also used in the production of daily necessities, such as toothbrushes or small plastic toys. Many medical devices, including valves and syringes, are also manufactured using plastic injection molding.
Plastic injection molding has a short production cycle and high productivity. The use of plastic injection molding can produce plastic parts with complex shapes, high size requirements and various inserts, which is difficult to achieve by other plastic molding methods; secondly, plastic injection molding It is easy to realize automation in the production process, such as injection, demoulding, and gate removal, and other operations can be automated. Therefore, plastic injection molding has been widely used. Except for a few thermoplastics (fluoroplastics), almost all thermoplastics can be processed and shaped by plastic injection molding. Plastic injection molding is not only used for the molding of thermoplastics, but also has been successfully used for the molding of thermoset plastics.
