Custom Insert Injection Molding
ExportPlastics offers high-precision insert injection molding solutions designed to combine performance, durability, and efficiency. We support a wide range of industries with tailored solutions that reduce costs, enhance part strength, and streamline assembly processes.
Reliable Results. Flexible Solutions.
Our advanced injection molding machines and robust quality systems ensure consistent, repeatable outcomes. By integrating polymer science with cutting-edge molding technologies, we help bring complex, high-performance parts to life—faster and more affordably.
Insert molding relies on mechanical bonding between a non-plastic insert and molten plastic. Because there’s no chemical adhesion between the two materials, careful part design and feasibility analysis are crucial to ensure long-term durability and function.
What is Insert Injection Molding?
Insert injection molding is the process of molding plastic around a non-plastic component, such as a metal insert. This creates a unified part that combines the strength of metal with the flexibility and efficiency of plastic. Common inserts include rods, studs, bushings, and threaded components.
