I. Advanced Springback Compensation
English: One of the most difficult challenges in steel header production is managing the "springback" of hardened steel. Our mould design utilizes Finite Element Analysis (FEA) to calculate the exact degree of material rebound. By integrating over-bending features and adjustable pressure pads, our dies deliver a final product that matches the CAD design within ±0.02mm, ensuring a seamless fit into the shoe assembly line and a high FPY (First Pass Yield).
II. Heavy-Duty Metallurgy for 24/7 Operations
English: Steel header production involves constant high-load impacts. To prevent die cracking and premature wear, we use H13 or DC53 premium tool steel, treated with vacuum quenching and multiple tempering cycles. The contact surfaces are further enhanced with TiAlN (Titanium Aluminum Nitride) coating, which provides extreme thermal stability and hardness (up to 3300 HV). This prevents "cold welding" and friction-induced galling, significantly extending the die life under high-tonnage pressure.
III. Ergonomic Contour Precision
English: Safety is critical, but fit is essential for market success. Our moulds are engineered to create smooth, ergonomic contours that accommodate various foot widths (6-point to 12-point sizes). The precision of the "flange" area-the part that secures to the sole-is meticulously controlled to ensure no sharp edges remain, preventing damage to the shoe leather or synthetic liners during the lasting process.
