The Basics of Rubber Extrusions

Rubber extrusion is a process where uncured rubber components are forced through a die and into a standard or customized shape. Once a piece of rubber is extruded, it is immediately cured.
This process of rubber extrusion uses an extrusion die, or a steel blank, that is a precision cut to the shape of the cross-sectional profile of the desired part. Once the extrusion die is in place raw material is forced through the die and cured to create the profile. Dies are material and durometer specific due to the unique characteristics of different materials used in the extrusion process.
Extrusion allows for a higher volume of material that can be processed in less time.
At ELBEX Corporation, our rubber extrusion process utilizes a a continuous salt bath cure line. Uncured extrusions run through a salt line at approximately 400 degrees Fahrenheit and will emerge fully cured. Different materials in the extrusion will also be cross-linked.
The extrusion process lends itself perfectly to high volume production runs. But with our salt bath cure process, we are not restricted to limited production lengths seen in other systems.
With our main focus on custom design manufacturing, we do not have minimum order requirements at ELBEX. Instead, minimum orders rely on profile size and material.
