Overview of the Main Workflow of a Hydraulic Press for Stamping Silver and Gold Coins

A hydraulic press for stamping silver and gold coins permanently presses a relief pattern from a die into a metal blank. Due to its high pressure, smooth operation, and precise control, it is the preferred machine for producing high-quality silver, gold, commemorative, and proof coins. The entire process is typically well-paced, and high-speed hydraulic presses can stamp dozens of times per minute. Below, see what the Jianlong Hydraulic Technology editor has to say for your reference when purchasing!

1. Loading: An operator or robot precisely places the polished, cleaned, and bright blank into the lower die cavity.

2. Closing: The machine starts, and the upper die (male die) moves smoothly downward, driven by a hydraulic cylinder, closing with the lower die (female die).

3. Stamping/Pressure: At the moment the die closes, the hydraulic system applies a preset pressure of hundreds of tons. The gold blank undergoes plastic flow within the sealed cavity, filling every detail of the die.

4. Holding Pressure: Pressure is maintained for an extremely short period (in milliseconds) to ensure complete molding. 5. Die Opening: The hydraulic cylinder returns, and the upper die lifts.

6. Ejection/Removal: The ejector mechanism ejects the stamped gold coin from the lower die, where it is removed by the operator or an automatic pick-up device.

The process of a hydraulic press for stamping silver and gold coins is a precision manufacturing process that perfectly combines metal, pressure, and art. It's more than just hammering out a pattern; it uses controlled, intense static pressure to "transfer" a work of art from the steel die to the precious metal, ultimately creating a fine coin with collectible and investment value.
