What Are The Reasons Why The Dies Used Make Gold Medals And Coins Undergo A Process Of Vacuum-Hardening?
The vacuum hardening of dies used to strike gold coins and medals is accomplished by exposing them to high temperatures under controlled conditions inside a vacuum chamber. Here's a quick guide on how to vacuum harden dies.
The dies used for striking coins or medals are prepared by making sure they are clean and free from any traces of contamination or residues.
Loading into vacuum furnace
The dies are placed inside a vacuum furnace, which is a special heat-treating chamber capable of creating a vacuum environment.
Evacuation from Air-
The vacuum oven removes all air from the room and creates a safe environment without oxygen as well as other gases. This helps to prevent the oxidation process while also ensuring a an even heat treatment.
Heating Phase
The furnace is heated to the required temperature to allow the dies to harden. The range of temperature is determined by the material type and the hardening process.
Soaking at high temperatures
Die dies are kept at an elevated temperature for the exact duration required to ensure the material is able to reach and maintain the required hardness.
Cooling and Quenching
With the help of special techniques that allow dies to be quickly cooling down or being quenched following the soaking process. The rapid cooling aids in locking in the desired hardness and strength in the steel.
Tempering (Optional).
In some cases, the hardening process is followed by a tempering procedure. The dies are reheated to a lower heat to ease internal stress and increase toughness, while maintaining hardness.
Quality Control and Inspection-
The hardened dies undergo thorough quality tests and inspections to confirm they are in compliance with the requirements for toughness, hardness, and tolerances to dimensional dimensions.
Post-Treatment Handling-
Dies, once the process of vacuum-hardening is complete, could be further processed using polishing and coating before they are used in strike of coins or medals process.
The process of vacuum hardening improves the durability of the dies, their wear resistance and the life of the dies that are used for making gold medals or coins. This process, which creates an environment free of airborne contaminants, ensures that dies are consistently hardened and reliably, contributing to both the quality and longevity of the products.

What Is The Reason Dies Are Polished By Hand In Order To Provide An Even Surface For Gold Medals And Coins?
Hand-polishing dies with care is essential in the production of gold medals and coins to ensure a smooth and flawless surface. There are a variety of reasons for this. Detail Reproduction - Hand polishing eliminates any imperfections, burrs or any irregularities that may occur on the die's surface. A smooth surface allows better reproduction of intricate details and the fine details of the design onto created medals or coins.
The polished die will ensure that the medals or coins struck have sharp edges, clear details, and a good relief. The final product will be of an improved aesthetic and appeal.
Polishing can reduce wear and tear during the process of striking. A smooth surface on the die reduces the chance of inconsistent or flaws appearing on coins or medals struck with rough surfaces.
Consistency of Striking - Die dies that are hand-polished ensure uniformity throughout the process of minting by ensuring an even strike area. Consistency ensures the accuracy and quality of the designs on all coins or medals.
Longevity of the DiesDies that are well-polished are less prone to damage or wear in the striking process. They are more durable and are able to be used for a greater number of strikes, without sacrificing quality.
Accuracy and Precision - Hand polishing allows the engraver to fine tune specific areas of dies, which ensures the details are accurately replicated on the struck medals or coins. This level of precision is crucial to the accuracy of the finished product.
Quality Control - Polishing is a part of the process for quality control. The die can be inspected during the hand-polishing process to find any imperfections or inconsistencies and corrected before the die is struck.
Surface Finish- Polishing provides a unique surface texture or finish to medals and coins, enhancing their appearance.
Overall, hand polishing gold dies and medals to perfection is essential to create high-end, highly precise, and visually pleasing products. It significantly improves the appearance of the final product as well as consistency, and durability.

How Do You Feed Gold Blanks Into Coin Presses?
During minting gold medals and coins are produced by stamping them under pressure. This article provides a brief description of the steps in loading blanks.
A feeder system is connected to the coin press. The system is loaded with gold blanks that have been prepared and checked for quality. This feeder ensures that blanks are constantly delivered to the machine.
Feeding Blanks in the Press
The feeder system feeds the blanks into the strike chamber inside the coin press one at a. This guarantees the exact positioning of each blank prior to stamping.
Alignment and Positioning
In the press, the blanks must be positioned perfectly within the area of striking, so that stamping can occur.
Striking in High Pressure
A coin press applies pressure on gold-plated blanks using two dies, one stationary and the other moving. The stationary die leaves a negative impression on the design of the coin while it is moving that die acts as the hammer, which hits the blank.
The moving die strikes the blank with considerable force, transferring the design to the surface of the blank. The force exerted by dies creates the design which creates the raised relief and details on the coin, or medal.
Striking repeatedly is optional.
Multiple strikes can be utilized to create a more sharply defined design or image on better quality medals and coins. Each strike refines the finer details of the surface of the blank.
Collection and ejection
The medals or coins will be ejected and placed in containers or trays when they have been struck. They undergo inspection for quality control in order to ensure that the stamped designs meet the standards and requirements set by the manufacturer.
Post-Processing-
The design of the medal or coin might require additional processing such as edge lettering (either edge or reeding) or post-strike treatments.
High-pressure stamping which imparts a design on the gold blanks is vital in that it converts them into finished coins or medals that are used for circulation, collecting, or commemoration. This process is extremely precise, since any change in pressure or alignment will impact the quality of the final piece.
