Technical Product Introduction
At Dongmo Precision, our Safety Shoes Steel Header Mould is not just a tool; it's a precision-engineered solution for high-risk safety components. Designed to produce steel toe caps that withstand a 200-Joule kinetic impact and 15kN compression, these dies are crafted for consistency and longevity.
We utilize CAE simulation (AutoForm) during the design phase to calculate precise material flow and springback, ensuring that each header fits the shoe last perfectly without secondary adjustments. This is essential for maintaining the structural integrity of high-tensile carbon steel.

Stress-Relieved Design: Unlike low-cost moulds, our steel header dies undergo vacuum heat treatment and multiple tempering cycles, reaching a stable HRC 60-62. This eliminates internal stress, preventing mould cracking during high-speed production.
Anti-Galling Surface: We apply TD Coating on the drawing inserts. This creates a surface hardness of over HV 3000, virtually eliminating metal pickup (galling) when stamping high-strength steel, which significantly reduces downtime for polishing.
Precision Trimming & Flanging: Our optimized trimming sequence ensures zero-burr edges. This precision is critical because any sharp edge on a steel toe cap can compromise the safety footwear's final assembly and wearer comfort.
Rapid Interchangeability: The mould is built with a standard die set and interchangeable sub-plates, allowing for quick size adjustments (EU 38 to 47) without removing the entire die from the press.
5-Stage Production Process
Shearing & Blanking: Precision blanking of high-carbon steel with optimized clearance.
Primary Drawing: Deep drawing the dome shape with controlled material thinning.
Side-Wall Piercing: (Optional) If ventilation or specialized attachment is required.
Accurate Trimming: High-speed edge trimming to ensure a uniform profile.
Bottom Flanging: Forming the structural base for superior compression resistance.
Professional FAQ
Q: How does Dongmo handle the springback issue of high-tensile steel? A: We use compensatory geometry based on FEA (Finite Element Analysis) results. This ensures that after the steel header is released from the die, it returns exactly to the intended CAD dimensions.
Q: What is the maintenance interval for the drawing ring? A: With our TD coating treatment, the drawing ring typically maintains its surface integrity for 300,000 to 500,000 cycles before requiring minor inspection, significantly outperforming standard chrome plating.
