Process classification of metal stamping

1. Cold stamping metal processing at room temperature is generally suitable for billets with a thickness of less than 4mm. The advantages are no need for heating, no oxide skin, good surface quality, easy operation, and low cost. The disadvantage is that there is work hardening phenomenon, which can cause the metal to lose further deformation ability in severe cases. Cold stamping requires a uniform thickness and small fluctuation range of the billet, with a smooth surface, no spots, no scratches, etc.
2. Hot stamping is a stamping process that heats metal to a certain temperature range. The advantages are that it can eliminate internal stress, avoid work hardening, increase material plasticity, reduce deformation resistance, and reduce equipment power consumption.
