产品说明
This high-safety-grade stretching die is specifically designed for mass production of metal gas cylinders. Made from high-wear-resistant alloy die steel and professionally hardened, it boasts exceptional hardness and fatigue resistance. Suitable for deep stretching of carbon steel, stainless steel, and other gas cylinder substrates, it effectively overcomes pain points such as uneven wall thickness, wrinkling, and bottle mouth deformation during stretching, ensuring forming safety from the outset.
The die cavity undergoes ultra-precision polishing and anti-sticking treatment, ensuring forming precision strictly meets the GB150 pressure vessel manufacturing standard. It precisely controls the uniformity of gas cylinder wall thickness, bottle mouth coaxiality, and roundness tolerances, ensuring stable pressure bearing, reliable sealing, and no leakage risks in the finished product.
It supports customization of gas cylinders of different capacities and pressure ratings, seamlessly integrating with automated stretching production lines. Equipped with an adaptive edge clamping and smooth ejection mechanism, it significantly reduces the defect rate, extends die life, and lowers die replacement and maintenance costs, helping companies efficiently mass-produce compliant and qualified products.
