What Is The Reason And How Do Gold Blanks Of Top Quality Weighed And Measured Before The Process Of Minting Begins?
To make gold coins or medals that are precise and consistent, gold blanks need to be carefully prepared. Preparation Process: Gold Material Select- For the creation of blanks the most pure metal is chosen. The gold will be refined to meet the purity standards for coins.
Gold Blanks Production- Gold is made into blanks via an approach known as blanking or cutting blanks. Blanking involves cutting coin-sized discs or planchets out of the gold material using specialized machines or stamping techniques.
Precision Weighing & Measuring
Weighing. Each blank is independently weighed, to make sure it is within the requirements of the coin. This procedure ensures that the medal or coin contains exactly the right amount of gold.
Measuringthe thickness, diameter as well as the overall dimension of every blank are measured using precision instruments to ensure consistency and conformity to design specifications.
Inspection and Quality Control
Visual Inspection- Each blank is visually inspected to detect any imperfections on the surface, irregularities or impurities that might affect the quality of the final product.
Rejecting blanks with non-conformity To ensure consistency and uniformity Blanks that don't conform to the weight, size or quality specifications are rejected.
The Motives for Preparing
Consistency throughout the Minting Process A precise measurement and weighed blanks ensure uniformity. Consistency is key to achieving uniformity in the striking process and results in coins or medals having the same quality.
A precise gold content- The precise weight of each blank guarantees that the final medal or coin contains the desired quantity of pure, accurate gold.
Uniform Blanks - Prevent any variations in size or weight which may impact on the value of the medal or coin and legality, or its suitability for trade or circulation.
Quality Assurance - Strict control measures are followed in the process of making blanks to ensure only the finest quality blanks free from defects, proceed through the process of minting to reduce the chance of defects appearing in the final products.
Legal Conformity - It is crucial that coins for commemorative or circulation purposes adhere to specifications and meet the legal standards.
To make accurate, high value legal compliant coins or medals, it's essential that gold blanks be prepared with precision and consistency.

How Are Gold Blanks Fed And Stamped With High Pressure Into Coin Presses For Minting?
During minting, gold coins and medals are created by stamping them under pressure. This is a brief overview of the steps that are involved 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. The feeder system is responsible for ensuring an uninterrupted flow of blanks to the machine.
Feeding Blanks Through the Press
The feeder system is used to feed the blanks into the strike chamber inside the coin press one at a time. This allows for precise positioning of the blanks.
Alignment and Positioning
In the press, the blanks need to be perfectly placed in the striking area, so that the stamping can be completed.
Fighting Under Pressure
The coin press is made up of two dies: one stationary and the other one is moving. The stationary die has the negative designs engraved on the coin, while the moving die is used to strike the blank.
The die moves and strikes the blanks with great force. The design is transferred onto the surface of the blank. The pressure of the dies creates the design, as well as the raised relief.
Repeated Striking (Optional)*
Multi-strikes can be used to create higher-quality medals or coins like proofs or collector's editions. This will result in an improved and clearer appearance. Each strike refines the surface of the coin or medal.
Ejection and Collection
After they are struck, the coins and medals are released into tray. Quality control is carried out to ensure that the designs conform to the specifications.
Post-Processing-
In addition to edge lettering and reeding depending on the design specifications or mint specifications, certain coins or medals may undergo post-strike or other treatment.
Stamping gold blanks under high pressure is vital since it creates the desired design on the blanks of gold. They are then turned into finished coins or medals ready for collection, circulation or for commemoration. This process demands precision as any alterations in pressure or alignment could alter the appearance and performance of the end product.
