Hydraulic Deep Drawing Die For Stainless Steel Sink Bowl

Product Details:

Drawing Process & Lubrication System: The die employs a first draw, second reverse draw, and final sizing stage to achieve sharp bottom corners. A multi‑point hydraulic blank holder provides adjustable pressure zoning. An integrated flood lubrication system delivers high‑viscosity deep draw oil to the entire cavity, eliminating galling and scoring.

Cavity Surface Engineering: The drawing rings and punch are ion‑nitrided to a case depth of 0.15 mm, then polished to a mirror finish of Ra 0.03 μm. Critical radii are hand‑stoned. For additional anti‑sticking, the die can be coated with a tungsten disulfide dry film, allowing use with low‑viscosity lubricants.

Customization & Die Package: We design fully according to your sink CAD-single bowl, double bowl, or apron front. The project includes the draw die, trimming die, and hole piercing die as a set. We also supply die maintenance manuals and a recommended hydraulic press parameter sheet for seamless production startup.
