Engineering Focus: The Mechanics of the Deep Draw
Successful LPG cylinder production depends on managing the flow of steel under immense hydraulic pressure. Our tooling design addresses these technical pillars:
Lubrication Retention: The surface texture of our dies is precision-lapped to optimize lubricant distribution, preventing "dry spots" that lead to scratching.
Variable Blank Holding Force: We design our moulds to interface perfectly with modern press cushions, allowing for adjustable pressure to eliminate wrinkling at the flange.
Heat Dissipation: Utilizing high-thermal-conductivity die steels to manage the heat generated during continuous 24/7 operation cycles.
Key Parameters for Procurement
Tooling Material: SKD11 or DC53 Cold-Work Die Steel (Vacuum Heat Treated to HRC 60-62).
Thickness Control: Engineered to maintain a wall thinning rate of less than 12% in the critical shoulder area.
Interchangeability: Components are machined to global standards, ensuring easy replacement of wear parts without custom fitting.
Surface Hardness: Optional CVD/PVD coating for extreme wear resistance in high-output environments.
Reliability in Every Stroke
Zero-Defect Start: Each LPG Cylinder Mould undergoes a mandatory 500-cycle trial run with material testing before shipment.
Extended Maintenance Cycles: By optimizing the clearance between the punch and die (calculated specifically for HP295 steel chemistry), we reduce the frequency of die re-sharpening.
Global Compatibility: Designed to fit perfectly into Yizhong, Tianduan, or European-style hydraulic press systems.
