This Silicone Stretch Lid Mold is specially designed for manufacturing high-quality liquid silicone rubber (LSR) food storage lids and sealing covers. The mold adopts a 4-cavity layout to achieve efficient and stable mass production while maintaining excellent dimensional consistency and product quality.
Designed for use with LSR injection molding machines, the mold incorporates a cold runner system with four individual cold nozzles, ensuring precise material distribution, reduced material waste, and enhanced production efficiency. The mold is particularly suitable for food-grade silicone lids, vacuum-sealing covers, reusable stretch lids, kitchen storage accessories, and other silicone sealing products.
With corrosion-resistant S316 stainless steel cavity/core inserts and a durable P20 mold base, the mold provides long service life, excellent surface finish, and reliable performance under continuous production conditions.

The four-cavity configuration significantly increases production output while maintaining excellent part consistency. Each cavity is precisely machined to ensure uniform product dimensions and sealing performance.
The cold runner system is designed to keep the silicone material in a controlled uncured state before entering the cavities. This design minimizes material waste, improves material utilization, and shortens production cycles.
Each cavity is supplied through an independent cold nozzle, ensuring balanced filling and stable injection pressure distribution. This arrangement helps eliminate short shots, air traps, and dimensional variations between cavities.
This mold is specifically designed for Liquid Silicone Rubber (LSR) injection molding and is compatible with food-grade silicone materials.
