How Do You Feed Blanks Of Gold Into Coin Presses?
In the process of minting gold blanks are loaded into coin presses, where they are stamped under high pressure to transform into finished coins or medals. This is a brief overview of the process involved in loading blanks
The loading of gold-plated blanks into a feeder connected to the coin press takes place after they have been prepared, inspected and evaluated. This feeder system ensures that there is a constant supply of blanks for the press.
Blanks for Feeding to the Press
The feeder system directs each blank to the strike area of the coin presses. The feeder system makes sure that every blank is precisely placed to allow for stamping.
Alignment of Positioning
The blanks inside the press chamber are positioned, aligned, and oriented perfectly to allow for stamping.
Strumming at High Pressure
The coin press applies massive pressure on the gold blanks by using two dies: one stationary and one moving. The stationary die has the negative impressions of the design on the coin. The moving die is used to strike the blank.
The die that is moving strikes the blank with great force and then transfers the design onto the blank's surface. The force of the dies creates the design, as well as the raised relief.
Repeated Striking is Optional
In order to create designs or images that are sharper and clearer, multiple strikes can be applied to rare coins or collectible editions. Each strike refines the detail within the blank.
Ejection and Collection-
Once struck and minted, the medals or coins created are taken from the presses. They then are collected in containers and trays. They are examined for quality control to ensure that the designs stamped meet the specified standards and criteria.
Post-Processing-
According to the specifications of the mint or design the coins and medals could undergo additional treatments such as edge lettering or reeding or post-strike treatment.
The process of stamping gold blanks using pressure is crucial as it creates the desired design on the gold blanks. They are then turned into finished gold coins or medals ready for circulation, collection or commemoration. It is essential to be precise, since even a slight variation in the pressurization or the alignment of the gold-plated blanks may have a negative impact on the quality and look of the finished product.
