Rice Cooker Lid Injection Mold
Production tooling for rice cooker outer lids, inner covers, steam valve housings, hinge covers, control panel frames, and handle components. Engineered for sealing performance, steam resistance, heat stability, and PP / PC / ABS / PPS material systems used in small kitchen appliance assemblies.
Rice cooker lid molds are built for manufacturing appliance components that must satisfy sealing performance, steam exposure resistance, heat stability, and food-contact material requirements. Tooling is developed from customer CAD data with wall thickness verification, gating strategy, warp prediction, and sealing groove validation before steel procurement. Molds accommodate PP, PC, ABS, and PPS grades with attention to steam valve openings, hinge pivot geometry, and snap-fit assembly features. Deliverables include DFM reports, mold flow analysis, steel certificates, T1 sampling, dimensional inspection reports, sealing groove measurement data, and PPAP documentation packages suitable for small appliance OEM and Tier 1 supply chains.
