Plastic injection molding is a relatively common manufacturing process for manufacturing plastic parts. Using injection molding, you can make a variety of products, and the differences in size, complexity, and application can be large. Injection molding processes require 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 is finally cooled and solidified.
Plastic injection molding can generally be used to produce thin-walled plastic parts for a variety of applications, the most common of which is a plastic case. The plastic casing is a thin-walled casing that usually requires many projections indoors. These housings are generally used in a variety of products, such as household appliances, consumer electronics, power tools and car dashboards. Other common thin-walled products include different types of open containers. Injection molding can also be used to produce several everyday items, such as toothbrushes and small plastic toys. Many medical devices, including valves and syringes, can be injection molded.
The advantages of plastic injection molding can form complex shapes and details, excellent surface finish, good dimensional accuracy, high productivity, low labor costs, and waste recycling.
