Rubber extrusion is the process of manufacturing raw plastic materials into a formed profile using high heat, pressure, and a specially-created die. Through this process, a nearly endless array of extruded ubber products can be created. Rubber extrusion is ideal for high-quantity manufacturing.
Rubber Extrusion Process
The first stage of rubber extrusion sees raw rubber materials (or resin, generally in the form of small pellets) gravity-fed from a hopper into a specialized extrusion machine. Colorants and other additives can be added to the resin prior to the material being placed in the hopper. The rubber material passes through an opening at the bottom of the hopper into a tube called the barrel, where a rotating screw mechanism forces the resin down the length of the barrel. The barrel is heated to
