The creation of a rubber extrusion forces uncured rubber compounds through a die and into a desired shape. By utilizing the extrusion process, we are able to produce countless shapes and to form products to a desired project specification.
Once the rubber compounds are extruded, they are immediately cured. At ELBEX, we use a continuous salt bath cure lines which send the extrusions through the line at 400 degrees Fahrenheit. The extrusion emerges from the salt bath fully cured and the various compounds cross-linked.
The process of rubber extrusion, especially when coupled with the salt bath cure system, lends itself towards high volume production runs. A higher volume of material can be produced in a shorter time when compared to other methods.
Along with the rubber extrusion process, we can also produce extrusion tool and design dies. An extrusion die is a blank piece of steel precisely cut to your project specifications. This die is cut to the cross-sectional profile of your part and then used to force material compounds through during extrusion.
