Stamping moulds and progressive dies are core equipment for metal sheet metal processing, widely used in hardware accessories, automobile sheet metal and electronic parts production. Different from low-pressure moulds and die casting moulds used for molten metal forming, stamping moulds realize cold forming of metal materials through mechanical pressure, with different structural design and material selection standards. Xinfeng Machinery provides customized processing services for various stamping moulds, stretching moulds and progressive dies, adapting to different sheet metal processing working conditions.
Ordinary single-station stamping moulds and stretching moulds can only complete single-process processing such as punching and stretching, requiring multiple equipment cooperation to finish product forming, with low production efficiency and large cumulative error. Multi-station progressive dies integrate multiple processes including feeding, punching, bending, stretching and trimming on one set of moulds, realizing one-time forming of products. In industrial production, the production efficiency of progressive dies is 65% higher than ordinary stamping moulds, which can greatly improve the output of sheet metal parts.
In terms of precision control, high-precision progressive dies adopt integrated precision processing technology, with product dimensional tolerance controlled within ±0.008mm, suitable for electronic precision parts and automobile high-precision sheet metal components. The defective rate of batch production is only 0.8%, which effectively reduces material waste and production cost. Ordinary stamping moulds are limited by single-process precision, with a defective rate as high as 4.2% in long-term production.
In terms of material selection, stamping moulds mainly use high-hardness wear-resistant mould steel such as DC53 and SKD11. DC53 steel has better toughness and wear resistance, 50% higher than SKD11, and is not easy to collapse during high-frequency stamping. For thick plate stamping working conditions, high-strength alloy mould steel is selected to improve mould pressure resistance and service life.
In terms of application scenarios, single-station stamping moulds and stretching moulds are suitable for small-batch and multi-variety customized production, while progressive dies are more suitable for high-volume standardized batch production, with significant cost and efficiency advantages.
