Engineered for Resilience
Unlike standard stamping dies, our Head Stretching Mold utilizes a specialized alloy matrix treated with vacuum quenching. This ensures that the stress distribution during the stretching phase is uniform, preventing thinning or cracking at the knuckle radius of the tank head.
Friction Management & Surface Integrity
We prioritize the interface between the sheet metal and the die. By integrating advanced lubrication channels and optional TD coating, our molds significantly reduce frictional heat. This results in a mirror-like finish on the workpiece, eliminating the need for secondary polishing and reducing labor costs.
Modular Maintenance Design
To minimize downtime, the wear components of our stretching tools are designed for rapid replacement. The blank holder and punch inserts can be adjusted or swapped without dismantling the entire die set, providing your facility with maximum operational flexibility.
Precision Control of Springback
Our engineering team utilizes FEA (Finite Element Analysis) to predict material behavior. This allows us to compensate for springback directly in the mold design, ensuring that every "head" produced meets the exact geometric requirements of pressure vessel standards (such as ASME or GB).
