conical twin screw for extruder machine

Detailed Information:     1.  Diameter: ¢15mm to ¢300mm; Max. Length: <=10000mm
2.  Nitriding depth 0.5 - 0.8mm, hardness HV>900 3.  Material of barrel inside layer: Tungsten alloy with spraying surface, prolong life of screw 4.  Material of special parts: special alloy is welded on the flight of screw, easy wearing parts of barrel are made from anti- wear alloy. 5.  Barrel Heating zone: Aluminum die casting ring heater + Stainless steel shell + cooling fan.  6.  Cooling device: Fan with air as the media to provide accurate temperature control.   7. Barrel cooling method: cylinder surface groove, set with brass, aluminum heating tank and inner wind   circle, with oil cooling and air-cooling at the same time, more precise temperature control.       Plastic application: applied for all kinds of appended fiberglass, plastic and PPA, PPO, PPS, LCP, magnetism powder and PC special engineering plasticComponents of alloy powder: Ni + Co + Cr + W + Si + Fe + B + C, Depth of alloy layer: 1.2 mm-2.0 mm Hardness of alloy: HRC>65° Two stage type of barrel (material of powder outlet is Cr12MoMV, vacuum quenching)
and screw (powder output is treated by alloy), the using lifespan is long as twice
as common one's.       Double-alloy level: Level A - containing Tungsten of 40%                             Level B - containing tungsten of 25% Level C - containing tungsten of 9.5% Hardness of alloy: HRC56-65°           We can make all types of screws and barrels according to customer's requirement.
