Basic Infomation	Screw diameter :14mm-300*8000mm L/D = 10-40 Surface Roughness :Ra0.4um Linearity of the screw: ≤0.015mm Linear axis limit: ≤0.02mm Hardness after Hardening & Tempering: HB260-300 Fragility of Nitration:≤Two grade
General Terms	Means of transport: Ocean,Air,Express Production time: About 20 days after we receive the deposit and lead time will different according to the order quantity.
Warranty period	2-4years(Depends on the plastic raw materials) Bimetallic: much longer lifetime.
Competitive Edge	1.Long lifetime,low energy consumption. 2.Wonderful plasticizing 3. Top-quality bimetallic screw and barrel 4. High wear resistance, resistance to corrosion 5. Fast and On time delivery 6. Best customer after-sale service!

For its excellent anti-erosion and anti-abrasion characters,the bimetallic screw

and barrels are widely used in the extrusion lines.With HVOF high speed spraying
equipment,spray a layer of metal which melt on the screw surface;a melt-cast
method is adopted to get bimetallic barrel,which could conform its precise formation.

Application:
1)PVC sheet extrusion line,From film to plate, from the wafer to the thick slices, calcium powder content more than 5%

2)PVC/PPR pipe extrusion line,the calcium powder 80%-120%,150%-200%,250%-300%;
3)PVC profile extrusion line;
4)PVC palletizing extrusion line,Transparent granulation (create particle good diaphaneity, not yellowing - no exhaust
machine barrel),grey granulation (particle good color and luster, full - machine barrel with exhaust)
5)PVC foam production line,PVC free foaming, crust foaming,half crust foaming;
6)PVC/PE wood plastic extrusion line.

Conical twin screw featurs:

Conical twin screw cores water internal circulation series and screw cores oil cold outer cycle.
