Bimetallic Extruder Screw Barrel With High Performance Backing
1. Descriptions
A bimetallic barrel is highly used for manufacturing and construction process. It looks like a tube and completely filled with a powered metal at both ends. There are different types of bimetallic barrels available that are used for various purposes such as extrusion, injection molding and blow molding machinery. The benefits of using bimetallic barrel are provided a protective wear surface and also improve the wear life. It is specially designed with perfect energy transfer between the backing material and bore.
The amazing features of bimetallic barrels are given below:
1. High performance backing
2. Bimetal construction
3. Bimetallic bore inlay
4. Inseparable inlay bond
5. Instant detection of process condition changes
6. Uniformity of barrel zone temperatures
7. Immediate response to heat and cool commands
8. Effective engineered design
