Details
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.
Mold Design and Key Technology
Cold Runner System
The cold runner design keeps LSR material at a controlled temperature before injection, ensuring stable molding conditions and significantly reducing material waste during production.
Gate, Tear-Off Edge, and Venting Overflow Design
The mold is engineered with precise gating, tear-off edges, and exhaust overflow structures. This ensures complete filling, smooth demolding, and clean product edges, while maintaining good air evacuation during injection.
Double Lower-Mold Structure
The double lower-mold configuration allows alternating injection and demolding operations, effectively shortening cycle time and increasing production efficiency.
High-Precision Machining
Advanced CNC and EDM machining guarantee accurate alignment between glass inserts and silicone overmold, ensuring uniform thickness and strong adhesion.
FAQ
Q1: What are the main advantages of this injection mold for glass-overmolding pot lid?
It offers stable production, low material waste, efficient double lower-mold operation, and clean part edges due to optimized gate and venting design.
Q2: Why use a silicone injection mold for pot lid instead of traditional methods?
A silicone injection mold for pot lid provides better sealing, improved appearance, and longer service life compared with conventional rubber molding.
Q3: Is this mold suitable for mass production?
Yes. The silicone injection mold for pot lid is designed for high-volume production with a long service life exceeding one million cycles under proper maintenance.
