Many companies are starting to see the benefits of using liquid silicone rubber. They use it for its high performance features that can be shaped into different forms.

In general, the mechanical properties of liquid silicone rubber are very similar to those of other rubbers. One example is that it has high tensile strength and low elongation at break. Additionally, the viscosity and hardness of liquid silicone rubber can vary greatly solely based on its applications.

What is LSR used for?

Liquid silicone rubber for applications ranges from medical, mold making, and aerospace industries to consumer goods. LSR find its use in many different applications as it is an eco-friendly, biodegradable and has high temperature resistance properties.

When people wondering what is LSR used for? The most common application for liquid silicone rubber is the baby teether and nipple parts. LSR parts are used in a range of different industries. Their high transparent & softness & high temperature resistance plus toxic free feature make them an excellent choice for Baby-care and Medical products such as breast pump, nose vent etc.

LSR Injection Molding Processes

1. Raw Material

Choose the right hardness and type of the liquid rubber silicone (LSR) based on your product needs, there are 2 main type of LSR, food grade and medical grade for different used products.

2. Injection Machinery

We have two types of LSR injection molding machinery for different designs of silicone rubber products, Vertical and Horizontal, both can mold silicone rubber products but with different advantages.

3. Injection Molding

After check injection machinery is in good condition, our production technical staff will prepare material into the machine, adjust right parameters against SOP, and start mass production after QC approve the first sample.

4. Curing Process

Curing process is a key station, all LSR products needs baking at our oven machine under 200℃/4 Hours, and pass VOC test to make sure consumers will be satisfy our LSR products.

Step 5. Flash Removing and Packaging

The flash needs to be removed by hand working and conduct inspection 100%, then pack into box for our customers.
