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 period2-4years(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!


Bimetallic Screw production method:

Plasma Alloy Coating Spraying or Wc/Co Whole spray welding

The PTA powder plasma welding applies the positive and negative electrodes of arc welding, allowing the welding path to be completely, welded with the base material. The minimum possibility of the welding path becoming less rigid fully prevents the welding layer from peeling off – thereby effectively upgrading the life time of the screws.

Outstanding Features of Bimetallic Screw and Barrel:
Hardness HRC55-65 Outstanding corrosion-resistance.
Hardness layer reaches above 2mm thickness. Hardness does not decrease with depth.
Hardness does not decrease under normal temperature.
Abrsion resistance / wear resistance on the hardened layer is 2~3 times higher than that treated by conventional heat treatment.

We specialized in manufacturing many types of screws, the barrels can be applied on all types of injection moulding machine,rubber hot-feeding extruder, rubber cold-feeding extruder, pin barrel cold feed extruder, plastic extruder with different specifications for Haitian,Demag,Toshiba, Husky, Nissei etc.We can provide the models of screw including variable pitch and variable depth, variable pitch and equal depth, variable depth and equal pitch, and equal depth and pitch.Groove multi-die type, composite type, mixing type and separating type.
