What is a rubber extrusion process?
Rubber extrusion is a process used to manufacture rubber products. The process uses an extrusion machine to force synthetic or natural rubber material through a shaped die under high pressure. The material used is typically soft, un-vulcanized rubber. The process shapes the workpiece in a soft, pliable state, after which it is vulcanized to harden the workpiece into a usable final product.
A rubber extruder machine is composed of two primary parts. A heated shearing screw pushes the raw material along a conveyor as compounds are fed into the extruder. As the material moves along the conveyor, it is heated and softened to make it pliable. The softened material is pressurized by the shearing screw and forced into the die where it takes its final shape.
The extruded product is vulcanized (cured) in a heated pressure vessel. Products made this way include window, door, valve and gate seals, tubing, pads, bumpers and channels. Rubber items like rectangles, squares or any type of odd shape have probably been through an extrusion process.
Rubber extrusions from Hebei Shida Seal Group come in a wide range of shapes, sizes and options. Each extruded rubber profile offers its own set of uses and advantages. Creating a seal is one of the more common applications of rubber extrusion profiles, but they can also be used for noise cancellation, impact absorption, vibration control, and even as decorative trim on windows.
