The custom injection molding of Liquid Silicone Rubber (LSR) uses much of the same process and equipment as injection molding. In both processes, the mold is heated and closed before the uncured rubber is injected. Unlike high consistency rubber (HCR), also known as gum stock, liquid silicone is just that, a “high viscosity liquid” that comes in two parts, Part A and Part B.
