Mold development is the end-to-end engineering of production tools—designing, machining, testing, and validating injection molds or dies that produce consistent parts at volume. For the sanitary industry (shower heads, faucets, toilet seat parts, and other bathroom accessories), the process starts with DFM and CAD/CAM design, material and gate/cooling layout, and FEM validation, then moves to prototype tooling, precision machining, try-outs, and fine-tuning until samples meet dimensional, cosmetic, and cycle-time targets. Deliverables include validated samples, PPAP/FAI documentation, and production-ready molds that minimize scrap, shorten time-to-market, and control per-part cost.
