Silicone Molding

Main content start

Silicone molding is a process that creates durable rubber parts through a molding process in a defined cavity.

In the Product Realization Lab, 2-part RTV (room temperature vulcanization, or cure) materials are used. Molds can be made from plastics like acrylic and Delrin, but aluminum is also used for more durable molds.

Molds are typically machined, but 3D printing and laser cutting can also be used. RTV silicone materials are available to purchase as needed in the Lab.


  • Vacuum degassing chamber and vacuum pump
  • Digital scales for measuring material
  • Curing oven (accelerates the cure time of RTV materials)
