1. material preparation: firstly, the copper plate material needs to be prepared to ensure that it meets the specified standards and size requirements.
2. Heating: The copper plate needs to be heated to a certain temperature before high-temperature automatic forming. Heating can be carried out by furnace heating, induction heating or laser heating.
3. Automatic forming: After the copper plate reaches a predetermined temperature, it is plastically deformed according to the required shape and size by automatic forming equipment (such as press or punch). This may involve the application of pressure, impact force or shear force.
4. Cooling: After the copper plate is formed, it needs to be cooled to solidify its shape. Cooling can be achieved by natural cooling or accelerated cooling using a cooling medium.
5. Inspection and adjustment: The cooled copper plate needs to be inspected to ensure that its shape and size meet the design requirements. If adjustment is needed, further rework or shaping is needed. Copper coin is the common name of copper coin, which is the general name of all kinds of new copper coins cast in China since the late Qing Dynasty and the early Republic of China.
