Detailed Analysis of the Liquid Silicone Encapsulation Process

In modern industrial design and manufacturing, a single material often cannot simultaneously meet multiple requirements such as structural strength, tactile comfort, and sealing protection. Liquid silicone rubber overmolding, as an advanced composite molding process, tightly bonds high-elasticity liquid silicone rubber (LSR) with rigid substrates (metal, engineering plastics, etc.), achieving rigid-flexible integrated product characteristics.

1. What is Liquid Silicone Encapsulation?

Liquid silicone encapsulation is essentially a two-shot injection molding technology. The basic process involves first creating a rigid substrate through conventional injection molding or machining, then placing it in a precision mold and injecting liquid silicone to coat the surface of the rigid substrate.
