Core Tool for Metal Drawing Processing

Drawing dies act as the core consumable tool in cold drawing production, directly deciding final workpiece dimension, surface quality and production efficiency. These precision moulds feature specially designed inner contour including inlet angle, working zone and calibration zone, guiding metal plastic flow during drawing.
Made of high‑hardness alloy or diamond materials, drawing dies need excellent wear‑resistance and pressure‑bearing capacity. Continuous friction with metal blanks will gradually wear the die inner hole. Once abrasion exceeds threshold, products will suffer size deviation and rough surface.
Regular inspection, polishing and timely replacement are essential in daily workshop management. Matching die aperture with target product specification is critical. Reasonable lubrication also reduces die loss and prevents workpiece surface defects. High‑quality drawing dies greatly lower rejection rate and extend service life of drawing equipment.
