Why Is Vacuum Hardening Used On Dies Used To Create Gold Coins Or Medals?
In order to harden dies for gold coins or medals, they are subjected to controlled temperatures inside the vacuum oven. This article will provide an overview of the process of vacuum hardening for dies.
When preparing dies to be used to strike coins or other medals, it is crucial that they are clean of contamination or residues.
The loading process is done in the vacuum Furnace
The dies are placed inside a special heat-treating chamber which can generate an atmosphere of vacuum.
Evacuation from Air
The vacuum chamber is created by eliminating air from the chamber, and then creating a controlled environment that is completely free of oxygen. This stops oxidation, and also ensures a uniform heat treatment.
Heating Phase-
The furnace is heated to the appropriate temperature to allow the dies to harden. The temperature range depends upon the specific material used and the method of hardening.
Soaking in high temperature
The material can attain the desired hardness, and the metallurgical structures are created.
Cooling or Quenching
Die dies are quenched or rapidly cooled after the soaking. This rapid cooling procedure assists in locking the desired hardness of the steel.
Tempering is optional
In some cases, a tempering process follows the hardening process. Tempering involves heating the dies at a lower temperature in order to reduce internal stress and increase the toughness of the die while maintaining its their hardness.
Quality Control Inspection
Hardened dies are subjected to thorough quality inspections and checks in order to meet the requirements for hardness, strength and tolerances for dimensional dimensions.
Post-Treatment Handling-
After the process of vacuum hardening dies are polished or coated prior to the time they are used in the coin process or the metal striking process.
The vacuum hardening procedure improves the strength, durability, wear resistance and lifetime of the dies that are used for making gold coins or gold medals. This process, which creates a safe environment that is free of airborne contaminants, guarantees that dies are hardened consistently and consistently, enhancing both the quality and durability of the products.

Why Do Dies Need To Be Polished By Hand? Ensure That Gold Coins And Medals Are Flawlessly Polished?
Hand polishing of dies is necessary for the production gold coins and medals. This is because it helps in the reproduction of the fine details. A smooth surface permits the intricate details of the design to be reproduced more accurately on the die-cast metals and coins.
Better Quality Coins or MedalsA die that is polished ensures that the struck coins or medals are sharp and have clearly defined edges, details and relief. It improves the aesthetics and quality of your final product.
Improved wear- polishing decreases friction and wear during the process of making strikes. A smooth surface on the die reduces the chance of inconsistent or imperfections appearing on medals or coins struck with rough surfaces.
Consistency is key when striking. Hand-polished dies provide an even surface for striking, which ensures uniformity. Consistency in design is critical to ensure accuracy and depth or overall quality on multiple coin and medals.
Longevity: Well-polished Dies are more durable. They are less likely than unpolished ones to break or get damaged during the strike process. They are more durable and have a longer durability, allowing to make more strikes without impacting the quality of the produced products.
Precision and Accuracy - Hand polishing allows engravers to fine-tune and refine specific areas of the die, making sure that the details are precisely replicated on the struck medals or coins. This precision is important for the accuracy of the final product.
Polishing for Quality Control is part of the quality control process. The examination of the die during polishing by hand is a method to find and fix any imperfections or defects prior to the striking process.
Surface Finish- Polishing can impart specific surface finishes or textures that enhance the appearance or bringing unique features to the coins or medals.
Hand polishing dies of gold medals and coins with care is a crucial step to make sure that the minted product will be high quality precise, accurate, and pleasing on the eye.
