- Three Elements of Metal StampingRequirements for stamping materials
1 .The thickness is accurate and uniform.
2 .The surface is smooth, no spots, no flaws, no scratches, no surface cracks, etc.
3 .The yield strength is uniform and there is no obvious directionality.
4. Uniform elongation is high.
5. The yield ratio is low.
6. Low work hardening.
In actual production, usually use the process test similar to the stamping process, such as the drawing performance test and the bulging performance test, which is used to test the punching performance of the material to ensure the quality of the finished product and high qualification rate.Requirements for Stamping Moulding & DiesThe precision and structure of the mold directly affect the forming and precision of the stamping. Molds manufacturing costs and longevity are important factors influencing the cost and quality of stampings. Standardization of mold bases, formwork, guides and development of simple molds (for small batch production), composite molds, multi-station progressive molds (for mass production), and the development of rapid mold change devices to reduce the workload of stamping production preparation and shortening the preparation time, the advanced stamping technology suitable for mass production can be reasonably applied to small batch and multi-variety production.Special Stamping EquipmentMechanical presses are generally used. Centered on modern high-speed multi-station mechanical presses, equipped with unwinding, leveling, finished product collection, conveying and other machinery as well as mold libraries and rapid mold change devices, and using computer program control, can form a high-productivity automatic stamping production line.Metal Stamping Parts
