Companies and organizations all over the world like to give challenge coins to their members to commemorate special occasions. Each coin represents a group's achievement, belonging, and camaraderie. People frequently ask how challenge coins are made because they mean so much to so many people. If you know the steps, the process of making the coin is relatively simple to understand. Here's how to create a challenge coin.
Every challenge coin starts with a design. With the development of high-powered computers and CNC machines, this process has become much more automated. It all starts with creating a design in a computer-aided design (CAD) system. This enables a CNC machine to precisely cut the pattern onto a piece of metal that will be utilized later in the process.
A challenge coin's design is only limited by the manufacturer's capabilities. Many aspects of the coin can be altered, including its size, substance, finish, color, and shape. Furthermore, specific design features can be introduced as long as the computer understands what you are attempting to do.
Once the design has been developed in the CAD system, it is sent to the CNC machine and broken down into cutting instructions. This CNC machine can cut solid metal into a certain shape. It transfers a negative image of your design onto a huge chunk of metal known as a die or mold. This effectively takes your design and removes the spaces between the elements of it. As a result, it can be used to create a replica of your design on another piece of metal.
Each coin necessitates the use of two molds, one for the front and one for the back. These molds are often composed of a highly hard metal, such as steel, that can endure high pressure without bending or destroying your design. No matter how many coins you order, only one mold set is required to complete a production line.
The next step is to begin manufacturing the coins with the die or mold established. Coin blanks are pressed with the mold set to imprint your design on both sides. This is known as die striking, and it takes a massive machine to provide enough pressure to alter the coins. Depending on how many coins you order, an experienced operator can execute this section pretty rapidly.
The coins are verified throughout the process to ensure that the designs are properly stamped. Any coin having a flaw is either repaired or removed from production and replaced with a new duplicate.
The coin's edge can have a distinct design. There are numerous possibilities available, and how they are constructed depends on which option you select. Among these alternatives are:
Rope (die stuck)
Chain (die stuck)
Spur (die stuck)
Flat (die stuck)
Custom edges (die stuck)
Beveled (Machine cut)
Scalloped (Machine cut)
Oblique (Machine cut)
Cross Cut (Machine cut)
Reeded (Machine cut)
The edge design is mostly determined by personal taste. Each alternative includes qualities that can complement the other side of the coin. It is something to consider while considering ways to improve the design of your currency.
Metal that has been stamped or cut might have some sharp edges and burrs. Before proceeding with the operation, these burrs must be removed. There are various methods for accomplishing this, including doing it by hand. Several machines, however, can automate this procedure.
After the polishing process is completed, each coin is examined for flaws. It may be able to repair any flaws discovered at this time. Quality checkers, on the other hand, are particularly focused on ensuring that every coin that is finalized is of the highest quality. It is not uncommon for them to recall coins with minor flaws from manufacturers.
The process of covering a coin with a different substance is known as plating. Coins composed of precious metals, such as gold or silver, are not wholly formed of those things. This would make each coin extremely valuable. They are instead composed of more common materials like copper, zinc, and iron. The coin's surface is then covered with a layer of gold or silver. A variety of chemicals are used in this operation to clean the coin and aid the transfer of the plating material to its surface. Click here for 3D Logo with Double Plate Brass Challenge Coin.
Coloring is the process of applying different colors to your coins. This can be done by machines or by hand with the use of appropriate tools. Enamel paint is used to fill in blank places in your design. The level of detail provided by the colors in your design is determined by how they are applied.
If you want a design with more color and detail, there are various options. Images can be printed directly on coins in some situations. This option provides the best visual quality of any of the options.
Finishing is frequently accomplished in more than one stage of the process. A finishing method is utilized before or during the polishing process. There are various approaches to this, including:
Sandblasting (Happens before the polishing process)
Flat/matte finishing (Happens before the polishing process)
Brushing (Happens before the polishing process)
Polished (Happens during the polishing process)
Because the components of the coin are polished at different times, they have varied finishes. A coin, for example, can have a flat finish applied to flat parts before polishing to give it a matte appearance. The raised edges can later be polished to make them gleam. The combination of these finishes results in a more complex design by creating a contrast between the edges and the other surfaces.
During the plating process, the finish can also be modified by selecting a different material. Although gold and silver are popular choices, they are not the only ones. This increases the color contrast while maintaining a shiny appearance.
