Why Do Gold Coin Or Medal Dies Go Through A Process Of Vacuum Hardening?
The process of vacuum hardening used for dies in striking gold coins or medals involves placing the dies in extreme temperatures and controlled conditions within a furnace that is a vacuum. Here's a quick guide on how to make dies harder by vacuum.
When creating dies to be used for striking metals or coins, it's crucial that they are clean of any residues or contaminants.
Loading in Vacuum Furnace
The dies will be put inside a chamber of vacuum, which is a specialized heat-treatment room that can create vacuum.
Evacuation Air
The vacuum oven removes all air from the room and creates a safe environment without oxygen as well as other gases. This assures uniform heating and prevents oxidation.
Heating Phase
The furnace then gets heated up to the temperature desired for hardening dies. Temperature ranges vary depending on the material and hardening processes.
Soaking in High Temperatures
The dies must be held at the high temperature for a specific duration to allow the material to achieve and maintain its desired hardness.
Cooling or Quenching
Die dies are immediately cooled off or quenched following soak. The rapid cooling process aids in locking the desired hardness of the metal.
Tempering is optional
In some cases, the process of hardening can be followed by a tempering process. Die dies are heated at a lower temperature to lessen internal stress and increase the toughness of the die, while preserving its hardness.
Quality Control and Inspection-
Hardened dies are subjected to rigorous quality inspections and tests to ensure they meet standards for strength, hardness and tolerances to dimensional measurements.
Post-Treatment Handling-
Dies, once the vacuum-hardening process has been completed, may be further processed, such as polishing and coating, before they are used in strike of coins or medals process.
The process of vacuum hardening enhances the durability, resistance to wear, and longevity of dies used for striking coins or medals. By creating a controlled environment free from atmospheric contaminants This process guarantees consistent and reliable hardening of the dies, contributing to the quality and longevity of the minted products.
