Rubber Extrusion

MID-STATES SPECIALIZES IN LARGE EXTRUSIONS

To create extruded rubber parts, rubber material is pushed through a die to form the part. The extruder is basically a cylinder or barrel with a helical screw inside that is forcing rubber through the extruder barrel and out the die. We offer both hot feed and cold feed processes for rubber extrusions. In hot feed extrusion, the rubber strip that is fed into the machine must be pre-warmed and plasticized on a rubber mill prior to processing. In cold feed extrusions the rubber strip need not be warmed but can be feed into the extruder at room temperature eliminating a step in the process. The barrel and screw on cold feed extruders are much longer than on hot feed extruders, which allow the uncured rubber to be plasticized and warmed in the extruder before the rubber reaches the die. After extrusion, the parts are conveyed through a continuous curing line utilizing microwave curing or placed in an autoclave for curing before being cut into the required length.

We produce extruded rubber parts in a variety of shapes and sizes, from 3/8″ to 182″ to meet customer demands. We have capabilities to work with each customer’s specifications to manufacture the exact part for their exact application. Our experience in hot and cold feed extrusions guarantees that Mid-States will be able to exceed your expectations for extruded rubber parts and rubber extrusions.
