With the increasing use of LSR (liquid silicone rubber) products, the design requirements for molds are also increasing. Today, we will share with you some of the key points of liquid silicone rubber mold design.
LSR (liquid silicone rubber) mold design requires the following conditions:
180 - 220 °C electric heating or oil heating
Central positioning and clamping guide for molds that are not affected by temperature
Integrated vacuum system
Extremely high precision
Reduce gates through cold runners
Conventional gate systems are typically gates that are integrated into the mold. The cold gate system is a customer-defined mold and cold runner in the injection molding machine, closing the nozzle or opening the nozzle.

Suitable for part release solutions
The demoulding mainly includes three types of ejection, ejection and brush release. Among them, the release of the brush can best reflect the influence of machine precision on the mold.
