Injection molding is a specific production process in which molten plastic material is injected into a mold cavity. The molten plastic is then cooled and fixed. Although the mold design and manufacturing process is very complicated and precise, injection molding itself is a reliable method for producing high-quality plastic parts. It has the following advantages in production.
In the automotive industry, repeatability-or the ability to consistently produce the same parts-is critical. Because injection molding often relies on strong plastic molds, plastic parts produced using plastic molds maintain a high degree of consistency and repeatability.
Cost-effective for mass production
Although the manufacturing cost of plastic molds is extremely high, for mass production applications, injection molding reduces the total cost and time cost.
Extensive material selection
A significant benefit of using injection molding in automotive production is that the process is compatible with a variety of rigid, flexible and rubber plastics. In the automotive industry, various polymers are used for a variety of purposes, including ABS, polypropylene, acrylic, acetal, nylon, polycarbonate, and more.
High precision and surface finish
Injection molding is an ideal method for producing plastic parts with relatively simple geometries, resulting in a high surface finish. Manufacturers have many options when producing and processing parts, including various surface textures–such as smooth, rough, or matte–that are applied directly to the mold rather than molded plastic parts. Different plastic materials also affect the final surface finish.
