{{ variable.name }}
Our insert molding process integrates metal inserts (e.g., steel) into plastic parts during injection, creating robust components with high pull-out strength. Suitable for threaded inserts, electrical contacts, and structural reinforcements. Widely used in automotive, consumer electronics, and industrial equipment.
