Rubber Extruder Machines
Hot feed screw type extruders are heavy-duty machines built to suit individual needs. They are made in many different type and sizes to meet the production requirements for straining, extruding, tubing, slab production or contoured shapes. The extruders size depends upon the hourly output required and method of feeding and with a complete line of equipment is available to meet with all customers need.

The Cold feed Extruders have been developed for processing cold rubber compound. Since these machines, in addition to extruding profiles also plasticize rubber, they differ from hot feed extruders. They have longer screws, heavier gear boxes and higher drive power. According to present stage of development cold feed extruders can be used for extruding almost all rubber compounds which are processable on hot feed extruders. Feeding is normally in the form of strips or pellets. Machines with longer screw diameters are often fed directly with wig-wag stored slabs.
