What Is Liquid Silicone Rubber Injection Molding?

Learn how LSR injection molding uses two-component liquid silicone rubber, precision dosing, mold design, injection control, curing, and demolding to produce stable silicone components for high-volume applications.

Learn More About LSR Technology

Liquid Silicone Rubber injection molding is a manufacturing process that uses two-component liquid silicone materials combined with precision dosing, mixing, and injection technologies to produce silicone components.

Compared with traditional solid silicone processing, LSR molding offers:

Higher production efficiency

Better dimensional consistency

Reduced manual error

Higher automation capability

Improved suitability for complex geometries

Better scalability for mass production

Once cured, liquid silicone rubber provides excellent flexibility, chemical resistance, thermal stability, and long-term durability, making it an ideal material for demanding applications.
