The LSR glass overmolding pot lid injection mold is specifically developed for producing high-quality cookware lids by overmolding silicone onto tempered glass. This injection mold for glass-overmolding pot lid adopts a cold runner system to ensure stable production, precise material control, and minimal silicone waste. The mold is designed with a multi-cavity layout and a double lower-mold structure, allowing one lower mold to be injected while the other is demolded, significantly improving overall production efficiency. High-strength tool steel and mirror-polished cavities ensure excellent durability and long mold life, suitable for continuous mass production.
The cold runner design keeps LSR material at a controlled temperature before injection, ensuring stable molding conditions and significantly reducing material waste during production.
Advanced CNC and EDM machining guarantee accurate alignment between glass inserts and silicone overmold, ensuring uniform thickness and strong adhesion.
