As you read this, you may be planning to start your silicone project and are struggling to find a suitable silicone manufacturer, after all, silicone rubber now is an environmentally friendly material that does not harm humans, Today’s article lists some well-known silicone manufacturers in the United States and will give you some tips on how to choose. I hope it will help you.

What is Silicone Manufacturing?

Silicone manufacturing as its name shows is the process of making products using silicone, a synthetic polymer made from silicon, oxygen, carbon, and hydrogen. The manufacture of silicone involves mixing raw materials such as silicon metal and carbon, heating them to high temperatures, and treating them with chemicals to form silicone polymers. The resulting silicone polymers can be molded, extruded, or formed into a variety of products such as silicone o-rings, silicone gaskets, silicone bellow, and more. Silicone manufacturing requires specialized equipment, expertise, and quality control to ensure the final product meets the required specifications.

Overview of Common Silicon Manufacturing Processes

(1) Liquid silicone injection Molding
Liquid silicone injection molding is a precise process that involves a pumping system to connect two containers of uncured liquid silicone rubber. One container contains a platinum catalyst (Type A), and the other contains methyl hydrogen siloxane (Type B). The metering system automatically releases the components at a 1:1 ratio, and any necessary pigment is added.

The injection molding machine can be customized with different platens, pistons, temperatures, injection rates, and cycle periods to ensure the precise shot size for the project. The machine heats the mold to the ideal temperature, adjusts the clamping force, and injects the liquid silicone rubber into the mold cavity.
The molding process requires ongoing heating and stressing until the material solidifies, and the cycle can be repeated for bulk manufacturing. After removing the components from the mold, post-molding services such as de-flashing, quality control, testing, and packaging are provided.
