More Details
This glass lid prototype reproduces the critical structural and functional characteristics of production lids to enable safe, accurate validation prior to tooling.
Tempered glass undergoes physical tempering to withstand laboratory-level rapid temperature changes (180°C–200°C) and mechanical impacts, simulating real cooking conditions. CNC-formed stainless steel edging achieves micrometer-level smooth integration with the glass, preventing oil ingress and edge looseness during cleaning or use.
Optical-grade transparency allows visual monitoring of food without lid removal. Edge curvature is controlled within ±0.5 mm to ensure perfect fit with the cookware body. Handles use multi-material injection molding—hard PP or soft silicone—to verify grip, slip resistance, and heat insulation. Screw fixation points are stress-optimized to prevent cracking under load; vertical pull tests support >5 kg without failure.
Additional engineering checks include: glass hole placement for venting (stress concentration avoidance), handle thermal conduction analysis (recommendation of insulating pads), and overall assembly gap verification. Prototypes are suitable for lab-level full assembly testing and ergonomic evaluation.
