Introduction of Liquid Silicone Rubber Injection Molding Process

Liquid Silicone Rubber Injection Molding Process

Liquid silicone rubber injection molding process is a highly efficient and precise manufacturing technique used in the production of various silicone-based products. This process involves injecting liquid silicone rubber into a mold cavity under high pressure, allowing it to cure and solidify into the desired shape.


Liquid silicone rubber (LSR) material is a highly versatile and durable substance that has found widespread use in a variety of industries. LSR is a type of silicone elastomer that is liquid at room temperature and can be easily molded into complex shapes. It is made from a mixture of silicone and other additives, which are then cured to form a solid material.


The process begins with the preparation of the silicone material, which is typically a two-part liquid silicone rubber (LSR) that is mixed and degassed to remove any air bubbles. The LSR is then injected into the mold cavity using a high-pressure injection unit. The mold is held closed under pressure until the silicone cures, which can take a few seconds to a few minutes depending on the material and part geometry.

Benefits of LSR Injection molding

One of the key advantages of liquid silicone rubber injection molding is the ability to produce parts with a high level of detail and complexity. This is due to the high flowability of the liquid silicone, which allows it to fill even the most intricate mold cavities. Additionally, the process can produce parts with tight tolerances and consistent wall thicknesses.


Another benefit of liquid silicone rubber injection molding is the ability to produce parts with excellent mechanical properties. Silicone materials offer high tear strength, elongation, and resilience, making them ideal for applications that require flexibility, durability, and resistance to extreme temperatures.


Overall, liquid silicone injection molding is a versatile and efficient manufacturing method that offers numerous advantages over other molding techniques. Its ability to produce complex shapes with high precision, consistency, and mechanical properties make it an ideal choice for a wide range of applications across various industries.
