Cold Feed Extruders

In almost all fields of rubber extrusion, the Cold feed Extruders are fast replacing the conventional Hot Feed Extruders. The elimination of the warm up mill before feeding a cold feed extruder contributes to economic sense and reduced heat cycle for the rubber compound. The Cod Feed extruders also improve the geometric stability of the extrusion. The final die pressure achievable is also 30 percent higher. Well defined zone temperature controls are possible for scroll, barrel and die head with separate circulation systems for each zone resulting in superior quality for the product. A vertical helical reduction unit, hinged feed roll assembly and pressure transducer in the head are all in tune with the latest trend. Compared to Hot Feed Extruder, the output of Cold Feed Extruder for the same size of the scroll, is much higher, resulting in reduced effective power input.
