5. Bimetallic alloy centrifugal casting for barrel
Hard-chrome plating hardness after nitriding:≥950HV
6. Hard-chrome electroplating
Chrome-plating layer depth:0.03-0.09mm

We use special alloy powders being sprayed and welded on the screw's ridge with diferent alloy and welding methods for different function.
For faster feeding, line grooves and helix grooves could be processed on the barrl inner wall.
We are one station screw and barrel solution.
We focus on each process to make sure every screw barrel is qualified and exact you want.
Engineers for measure are availabe oce size and drawings are not clear.
All screw barrels have one year- guarantee, while 3-5 years life time for nitriding ones, and alloy ones would be longer.
BATTEN is located in Zhoushan City, the largest manufacture base of Screw Barrel in China.
With 1500 SQ.M workshop, and 40 experienced emplyees are equiped at BATTEN.
