Metallurgical Integrity & Heat Treatment
The longevity of an LPG cylinder mould is won or lost in the vacuum furnace. We utilize a proprietary triple-tempering process on our D2/DC53 inserts. This creates a "tough-core, hard-shell" characteristic that prevents micro-cracking during the 600-ton impacts required for thick-walled gas cylinders.
Design Innovation: The Constant-Thickness Wall (CTW) Logic
Traditional moulds often result in thinning at the "apex" of the dome. Our engineering team has developed the CTW Geometry, which compensates for material flow velocity.
Result A: Uniform wall thickness for easier burst-pressure certification.
Result B: Significant reduction in pre-welding grinding time.
Comparative Performance Matrix
| Performance Metric | Standard Industry Tooling | Our Enhanced Tooling |
| Surface Friction Coeff. | 0.15 - 0.20 μ | < 0.08 μ (Nano-Coated) |
| Thermal Deformation | High (Requires frequent cooling) | Ultra-Low (Active cooling logic) |
| Scrap Rate (Thinning) | 2% - 5% | < 0.3% |
Lifecycle Support & Maintenance
We provide more than hardware; we provide a Maintenance Roadmap. Every tool set is shipped with a specialized "Wear-Indicator" coating. When the sacrificial layer changes color, your team knows it is time for scheduled polishing, preventing catastrophic die failure and ensuring a service life that often exceeds 1 million cycles.
