We have 10 sets of Cold Drawn Mills including 2 sets of Cold Drawing Machine with Floating Mandrels with Korea Lubricant Oil. Ensure the Roughness of the stainless steel tubing surface. And degreasing work is all finished manually, ensuring the brightness enough of stainless steel tubes. Final solution annealing finished with Bright Annealing Furnace. Without Pickling, So it will friendly to the Enviorment.

We have 4 Sets of Precision Cold Rolled Machines using highly polished rollers in touch with the stainless steel surface and control the velocity of the Pilger machine to ensure smoothness and brightness. Selected the best quality stainless steel round bar, clean and smooth on the outside surface and inside surfaces. Withstand high pressure, no deformation after cold bending, no crack and break after flattening and flaring, etc.
