Tooling Support
Trial molding, insert and overmolding tooling review, sample verification, and engineering support for plastic component tooling after mold completion.

Tooling Trial Support
This category shows sample parts and connector-related tooling support used to evaluate mold performance. The role is trial, verification, and engineering feedback around the mold before tooling release.
Trial review can focus on appearance, critical dimensions, terminal position, locking features, assembly fit, repeatability, and required tooling adjustments. Automotive connectors are a key application, with medical and industrial plastic component tooling reviewed according to project requirements.
