Tool Steel Die with Stamping Die Assembly and Cylindrical Guide Pillars

Tool steel's wear resistance and compressive strength make it the standard material for stamping die assemblies where punch-to-die clearance must be held within microns to produce clean shear faces and avoid burr formation. Ningbo Yujun machines this tool steel stamping die with cylindrical guide pillars using CNC milling and EDM under IATF 16949 and ISO 9001 certification at the Ningbo, Zhejiang facility. EDM is essential for die aperture and punch clearances; wire EDM cuts perpendicular, burr-free profiles that milling cannot achieve at the tolerances stamping dies require. The facility supports in-house anodizing, black oxide coating, and chemical plating, serving automotive, aerospace, and medical equipment applications. Guide pillar bores are machined to your running clearance callout to primarytain punch-to-die register over the die's service life. Provide your die drawing with punch dimensions, clearance callout, and guide pillar specification. Yujun will confirm the CNC milling and EDM sequence and submit a formal production quotation.
