The machine’s four-column and three-plate structure ensures that the die installation is accurate and stable, laying the foundation for precise embossing.
2. Metal Blank Placement: The processed precious metal blank (such as a silver coin blank, a copper nameplate blank) is placed between the upper and lower dies, and positioned accurately to ensure that the embossed pattern is aligned with the blank.
3. Hydraulic Pressure Application: After starting the machine, the hydraulic system drives the movable plate to move downward stably. Under the control of the four-axis precision linear self-lubricating guide sleeves, the movable plate maintains high vertical precision during movement, and the pressure is uniformly distributed on the metal blank through the upper die. The pressure can be adjusted according to the material and thickness of the metal blank to ensure that the pattern is fully embossed without damaging the metal.
4. Completion of Embossing: After the pressure is maintained for a certain period (adjustable according to the process requirements), the hydraulic system drives the movable plate to reset upward, and the embossed metal product is taken out. The entire process is completed under precise control, ensuring that the pattern on each product is clear and consistent.
