How Do You Feed Blanks Of Gold Into Coin Presses?
During the production process gold blanks are fed into coin presses which stamp them using high pressure. The result is completed coins or medals. This article will provide an outline of the steps that are involved in loading blanks
The loading of gold-plated blanks into a feeder attached to a coin press is done after they've been prepared, examined and evaluated. This feeder system is accountable for maintaining that blanks are continuously flowed to the coin press.
Feeding Blanks on the Press
The feeder system introduces blanks into the chamber for striking in the coin press one at a time. This guarantees the exact placement of each stamping blank.
Alignment and Positioning
In the press, blanks must be positioned perfectly in the strike area so that the stamping can take place.
Striving Under Pressure
The coin presses apply immense pressure on gold blanks by using a pair dies -- one stationary and one mobile. The stationary die has the negative impressions of the design engraved on the coin. The moving die is used to strike the blank.
The die is moved to strike the blank with great force and transfers the design on the blank surface. Die's pressure prints the designs, resulting in the reliefs raised and the details of the medal or coin.
The repetition of striking is not required.
To achieve a sharper image or a more distinct appearance, multiple strikes are sometimes applied to higher quality coins and medals, specifically proof editions. Each strike increases the clarity on the surface.
Ejection & Collection
Once struck by the press, the coins or medals that are created are taken from the presses. They then collect in containers and trays. They are examined for quality control in order to ensure that the designs stamped meet the standards and requirements set by the manufacturer.
Post-Processing-
Minted coins and medals can undergo additional procedures such as edge lettering edge reeding, or even post-strike processes based on the design specifications or mint specifications.
Stamping gold blanks with pressure is crucial because it creates the desired design on the gold blanks. These are then transformed into finished medals or coins ready for circulation, collection or even commemoration. Precision is required, as even the slightest deviation in the pressurization or the alignment of the gold blanks could result in a negative impact on the appearance and quality of the final product.
