The Silicone Rubber Injection Molding Process Explained

This video explains the silicone rubber injection molding process from start to finish.

Firstly, the injection molding machine is almost the same as the machine used for plastic injection molding. Both presses use the same parts, but liquid silicone rubber injection molding pressure is far lower than that used for themoplastics. The injection unit also runs cool, which is opposite to plastic injection molding which needs to be kept very hot to keep the plastic moving.

We will look at how silicone is delivered in drums, and the percentage of colorants in it to make them the color you desire.

I explain how it is possible to use the same machinery for both silicone and plastic injection molding, but that they need to be configured and treated differently for the different materials.

Finally, we'll look at the numerous advantages of LSR tooling and its costs, too.
