Custom plastic molding is a manufacturing process used to produce plastic parts in various shapes, sizes, and complexities. It involves injecting molten plastic into a mold cavity, where it cools and solidifies into the desired form. This method is widely used across industries such as automotive, medical, consumer electronics, and aerospace due to its efficiency, repeatability, and ability to produce high-precision components.
In this guide, we will explore the different types of custom plastic molding, their applications, benefits, and key considerations for selecting the right molding process for your project.
Injection molding is the most common custom plastic molding technique. It involves melting plastic pellets and injecting the molten material into a steel or aluminum mold under high pressure. Once cooled, the part is ejected, and the process repeats.

Applications:
Blow molding is primarily used to create hollow plastic parts, such as bottles and containers. The process involves inflating a heated plastic tube (parison) inside a mold until it takes the desired shape.
