Liquid silicone rubber molding parts has existed since the late 1970s and has become the stuff of choice for producing rubber products and parts. The distinctive features of liquid silicone injection molding make it different from convention molding high-consistency silicone and other thermoplastic injection molding processes.

Liquid silicone injection molding has 1000s of applications across a range of industries, including automotive, medical, general industrial markets, infant care, aerospace, electronics, and many other specialized industries. While liquid silicone rubber injection molding job best for little and long-run part production  can employ the process in the final stages of prototyping. The process is also perfect for the evaluation of different stuffs configurations before green-lighting a project for complete production.

Features of liquid silicone injection molding

Liquid silicone molding has become the perfect material for extremely demanding applications because of its special features, which contain:


Under big testing, liquid silicone rubber has demonstrated superior compatibility with body fluids and human tissue. In comparison to other elastomers, liquid silicone injection molding is resistant to bacteria growth and will not corrode or stain other stuffs. LSR is also odorless and tasteless and can be formulated to comply with stringent FDA needs.


Liquid silicone parts can withstand high temperature, which makes them a perfect choice for parts under the hood of vehicles and in close proximity to engines. Parts fabricated through liquid silicone injection molding are fire retardant and will not melt – a serious issue for parts created via plastic injection molding methods.

Mechanical features

Liquid silicone rubber has best elongation, high tear and tensile power, amazing flexibility and a hardness range of five to eighty shore A.

Electrical properties

Liquid silicone injection molding has amazing insulating features, which provide an attractive choice for a host of electrical applications. Matched to conventional insulating material, silicone can do in far higher and lower temperatures.

Pigmentation and transparency

Liquid silicone rubber forcers a natural transparency, this attribute makes it easy to generate, colorful, custom, molded items.

Temperature resistance

Matched to other elastomers, molded silicone can withstand a big range of low/high temperature extremes. For example, Silastic LSR for continues can remains table via temperature ranging from -60 C to +180C.

Chemical resistance

Liquid silicone injection molding resistant water, oxidation and some chemical solutions such as alkali and acids.
