Vulcanizing presses designed for making rubber molds. Rigid body made of aluminum and steel, rods with bush bearings keeping platens horizontal during vulcanization. A 120 minute timer also functioning as on/off switch, stainless steel face platewith digital temperature control keeping the plates at set temperature.
Vulcanization refers to a specific curing process of rubber involving high heat and the addition of sulfur. It is a chemical process in which polymer molecules are linked to other polymer molecules by atomic bridges composed of sulfur atoms. The end result is that the springy rubber molecules become cross-linked to a greater or lesser extent. This makes the bulk material harder, much
