This mold adopts DC53 cold work mold steel, which is treated by vacuum heat treatment to reach a hardness of HV850±50, with excellent anti-chipping performance, suitable for cold extrusion processing of high-hardness materials such as stainless steel. The hard chrome plating surface treatment improves the corrosion resistance and demolding performance of the mold, reducing surface scratches on fasteners. The cavity is processed by wire cutting precision machining to ensure ±0.005mm dimensional accuracy, and the produced fasteners have strong interchangeability. The high-speed discharge design can achieve 60 extrusions per minute, improving production efficiency by 25% compared with traditional molds.
Overall mold size: 350mm×250mm×180mm; Mold material: DC53 cold work mold steel; Cavity machining accuracy: ±0.005mm; Surface hardness: HV850±50; Surface treatment: hard chrome plating; Compatible extrusion press tonnage: 100-300Ton; Applicable material thickness: 0.5-3mm; Discharge speed: 60 times/minute; Single set mold weight: 8kg; Customizable fastener types: cross recessed screws, hex nuts, buckles and other hardware fasteners.
It is mainly used for batch production of stainless steel fasteners and hardware accessories, serving automobile parts manufacturing plants, electronic hardware processing plants and standard parts production enterprises. It can customize stainless steel fastener extrusion molds of different specifications according to customer needs, meeting the production requirements of high-precision and high-strength fasteners.
