Manufacturing dual-material plastic button keycaps requires precise control over both structural integrity and tactile feel. This case study details the engineering of a highly efficient multi-component mold designed to produce ABS and TPU overmolded keycaps.
This project required the seamless integration of hard plastic (PP) and a soft elastomer (TPE), combined with multi-directional mechanical actions to handle both internal and external threads, as well as side ports. Here is an in-depth look at the tooling engineering and mold structure that made this possible.
This article documents the mold structure, gating system, cavity layout, and complete 18-step molding sequence. It is intended as a reference for mold designers, process engineers, and tooling project managers.
This mold case study reviews a two-shot injection mold for an automotive interior trim component. The part is molded first in PC as the rigid substrate, then overmolded with TPE as the soft-touch functional layer.
