Product Description


Product Description
Pinned barrel, Cold-, hot- fed-extruder barrel and screw
The enterprise mainly produces cold-, hot-fed-extruder barrels and screws. Rubber-pinned-cold-fed screws and barrels are widely usde in txtruding all typesof rubber products and in supplying rubber er to calenders They can alsobe used extruding rubber tube rubber film inner tire,tire surface cover rubber of wire cable filtering rubber impurities and so on pin makes rubber machine-finishing more efficient and is a major component for high efficient and energy-saving equipments Our screws are innovated and have special geometric structure so they can completespecial difficult tasks like plasticizing mixing and extruding Barrel can also controltemperatures of each section ind ependently ordinary screw uses 38 CrMoAIA and is nitridinged on the surface so that it guarantees high distortion intensity and wear resistance The bimeatal barrel uses the special wear-resistance alloy by applying the centrifugal casting technolongy and its service life is higher than ordinary one
