| 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.
