1. Strict Selection of Corrugated Roller Material
The best manufactuer of 50CrMo alloy steel in China supply us raw material. Adequate raw material in warehouse can guarantee the delivery time for our tunsten carbide corrugating rolls.
2.Precision Welding Make Inseparable
The roll barrel and shafts shrink fit together. After welding do tempering to reduce stress. We do steam leak detction too.
3. Advanced Equipments
Intermediate frequency quenching machine.
High precison grinding machine with Siemens CNC system.
Sand blasting machine
It makes rough roll surface to increase adhesion of tungsten carbide powder.
American Praxair Tungsten Carbide Plating equipment.
Praxair 1342 super hard tungsten carbide powder
It is the best TC powder in the world.
Polishing machine
Special polishing mahine and technology for corrugating rolls. Smooth surface can extend the life span of tungsten carbide corrugating rolls.
4. QC
Test flute profile with computer and projector.
Flute profile test and paper test during grinding, after coating, after polising and finished prodcuts inspection. We make sure every set of corrugating rolls 100% qualified.
5. Package
Packed with solid wooden boxes.
