How Do You Feed Blanks Of Gold Into Coin Presses?
During the process of minting, gold blanks must be loaded into coin presses and stamped at high pressure so that they can become finished coins or awards. Here's a brief overview of how to load blanks.
Loading gold-plated blanks into a feeder that is connected to a coin press is done after they've been cleaned, inspected and evaluated. This feeder system is accountable for ensuring that blanks are continuously flowed to the machine.
Feeding Blanks in the Press
The feeding system was designed to direct the blanks one at a time into the chamber for striking. The feeder system makes sure that each blank is precisely placed to be stamped.
Alignment and Positioning
When using the press, blanks should be placed precisely within the area of striking, to allow the stamping process to take place.
Striving Under Pressure
A coin press is a device that applies high pressure on gold-plated blanks with two dies, one stationary and the other moving. The stationary die has the negative image of the design of the coin, and the one that moves is the hammer that strikes the blank.
The die moves and strikes the blanks with immense force. The design is transferred to the surface of the blank. The pressure of the dies imprints the designs, which result in the raised reliefs and details of the coin or medal.
Repeated Striking
Multiple strikes are a great way to create a sharply clear appearance or design on high quality coin and medals. Each strike refines the detail inside the blank.
Ejection and Collection
When the designs are struck by the press, the coins or medals that are created are taken from the presses. They then are collected in trays and containers. The stamped designs are inspected for quality to ensure they meet specified standards.
Post-Processing-
If the mint requires it, they may also apply additional processes like edge lettering, reeding the edges, or post-strike treatments.
Stamping the gold blanks with the highest pressure is crucial since it imprints the desired design on the blanks, transforming them into refined coins and medals which can be used for commemoration and collection, or even circulation. Precision is required, as even the slightest deviation in the pressure or alignment of the gold blanks can result in a negative impact on the appearance and quality of the finished product.
