Advanced Metallurgy & Wear Resistance
A Head Stretching Mold undergoes repetitive high-impact cycles. To combat premature wear and cracking, our design incorporates:
Composite Material Architecture: We utilize G20 or G30 Tungsten Carbide inserts in high-wear zones to maintain dimensional accuracy over millions of hits.
Elastic Recovery Control: Our engineering team calculates the precise "spring-back" of high-tensile steel, adjusting the mold geometry to ensure the final product matches the shoe last perfectly.
Multi-Stage Forming Process
To achieve the deep-draw depth required for protective footwear without material tearing, our tooling sets cover:
Initial Cup Stretching: Establishing the primary volume and wall thickness.
Refining & Shaping: Sculpting the specific ergonomic curves (Left/Right foot distinctions).
Bottom Flattening & Edge Coining: Ensuring a stable base for integration into the shoe sole assembly.
Punching & Branding: Optional integrated modules for size marking and ventilation holes.
Global Supply Chain Integration
For international footwear component manufacturers, reliability is the core KPI. Our Head Stretching Mold is designed for "Plug-and-Play" installation in high-speed mechanical presses. Each die set is vacuum heat-treated to $60\text{-}62$ HRC and undergoes rigorous 3D CMM inspection. We support diverse standards including European (EN), American (ASTM), and Canadian (CSA) profiles, providing the technical edge needed to compete in the global PPE (Personal Protective Equipment) market.
