1. Technical Architecture
Unlike standard stamping tools, our LPG Cylinder Mould series utilizes a proprietary heat-treatment process for the die inserts. This significantly reduces friction during the deep drawing phase, preventing "necking" or material thinning at the cylinder's critical stress points.
2. Performance Metrics
| Parameter | Specification Details |
| Material Compatibility | HP295, HP345, SG295, and other high-strength steels |
| Mold Lifecycle | Guaranteed 500,000 to 1,000,000 strokes (maintenance dependent) |
| Tolerance Precision | Within $\pm 0.05$ mm for dome consistency |
| Surface Finish | Mirror-polished to eliminate surface micro-cracks |
