Insert Molding vs. Overmolding: A Side-by-Side Comparison of Two Multi-Material Injection Molding Processes

A side-by-side comparison of two multi-material injection molding processes — when to use each and what each requires from the part design. Insert molding and overmolding are both multi-material injection molding processes that produce a single part integrating more than one material. Engineers frequently ask which process to use, and the answer depends primarily on […]
