Product Description


Advandages of bimetallic

1. Corrosion resisting,
Some plastic materials such as Fluorine,PVC,ABS or add additive GF,etc,when temperature rise higher,will send out corrosive gas, which will damage your screw and barrel.Common nitrided screw barrel can not service long time,But bimetallic screw barrel is different,the bimetallic layer could resist the corrosion,make the screw barrel working life longer.We guarantee you the working life is one year,but our customers always use several years.

2.Wear resisting
Some times,we also need to add some materials easy to wear,such as Caco3,or recycled materials,these materials are called bad materials.Common nitrided screw barrel also could not serve you longer. Maybe half year, you need to change one set. In this situation,if you use our bimetallic screw barrel,we can guarantee one year. But our customers always use several years.

We-HUACHEN bimetalilc standard:
1. Standard grade: 38CrMoAlA + nitriding 96 hours
2. Bimetallic grade: 38CrMoAlA + bimetallic alloy
3. HC-A grade: Tungsten carbide 40%
4. HC-B grade: Tungsten carbide 25%
5. HC-C grade: Tungsten carbide 15%

Two types of bimetallic screw:
The bimetallic also could divide two types, like the above picture show:
Type 1:Sparying the bimetallic on the screw flight,this is very common in the market. If your plastic material is not very very bad,we suggest you choose this type, because of its economy.
Type 2:Coating the bimetallic on the whole screw,this is new technical these years. The advantage:Working life more longer than type 1,the disadvantage: Price is also very higher than type 1.

Barrel bimetallic:

Two types of bimetallic barrel:
About the bimetallic barrel,we also have two types:
Type 1,Groove bimetallic,we will make a groove on the barel first,then spary the bimetallic on the groove.
Type 2.Centrifuge casting.Bimetallic will attach to the inner wall of barrel equably.
