Materials commonly used for medals
Medals are usually made of metal such as zinc alloy, brass or aluminum. The choice of material depends on the desired finish, budget and production process.
Zinc Alloy: Why are the medals made of zinc alloy? Zinc alloy is a popular choice for custom medals because it is cheap, lightweight and easy to work with. It can be plated with gold, silver or other finishes to give it a polished appearance.
Brass: Brass is a strong and durable metal that can be used to create custom medals. It can be plated with gold, silver or other finishes to give it a polished appearance.
Aluminum: Aluminum is a lightweight and cheap metal that can be used to create custom medals. It can be produced in different colors through anodization, and it is also a non-rusting material.
Considering the price, zinc alloy is considered to be the most cost-effective material among the above materials. It’s relatively cheap, lightweight, and easy to use, making it a suitable option for those on a tight budget.
Medal suppliers often make zinc alloy medal with medal making machine because it is cheap, lightweight and easy to work with. They can also be decorated using different techniques such as enamel, 3D or color printing to make them more attractive and unique. Now let me introduce the medal making process of zinc alloy medal.
Zinc Alloy Medal Production-Design drawings:
Create or receive design artwork for the zinc alloy medal, including required shape, size, logo, text and any other details.
Create using graphic design software or draw by hand and then digitize.
Select the raw material:
Zinc alloys can be melted with a low melting point of more than 420 degrees on average. And have good fluidity, corrosion resistance, and easy handling characteristics.
Due to the low melting point of zinc, the mold will not receive excessive heat during casting. Therefore, the mold has a longer service life.
The cost of zinc alloys is cheaper than other metal alloys.
Zinc Alloy Medal Production-Customize Mold :
According to the design drawings, create a mold to shape the zinc medal.
Zinc alloy medal is usually made of steel and consist of two halves, the “mold” and the “core”, which fit together to form the desired part shape. We need to create the number of cavities required for the mold based on the number of zinc alloy medal that need to be produced daily.
Zinc alloy medal castings:
According to the specific requirements of the zinc alloy medal and the design of the medal, set the injection pressure, injection speed, temperature control and other machine parameters of medal making machine.
Molten zinc alloy (a combination of zinc and other metals) is pushed into the mold.
After the molten metal cools and solidifies in the mold, open the medal making machine and take out the product, which will roughly form the desired shape of the medal.
Polishing and grinding:
The rough edges of the zinc alloy medal are trimmed off and then subjected to various processes. Such as grinding, polishing and polishing to achieve a smooth and shiny surface finish.
Color transfer and spraying:
The polished zinc alloy medal can be colored and spray-painted according to the medal suppliers design requirements to add color, texture and protective layer. To enhance the appearance and durability of the medal.
The difficulty of making zinc alloy medal mainly depends on the complexity of the carvings around the medals and the smoothness of the mirror in the middle of the medals. The smoother the mirror surface, the higher the difficulty of the medal making process. Because the metal raw material itself is rough, the mirror effect is very important for later laser engraving and other requirements. Therefore, in order to present a full mirror effect, when making zinc alloy medal, you can choose a larger medal making machine or reduce the number of cavities in the mold.
What kind of medals are suitable to be made of zinc alloy?
Badges, medals or commemorative coins that meet the following conditions can be made from zinc alloy, which can better reflect the design effect or reduce costs.
The number of products is thousands, or the size is relatively large, such as 35mm or more
The product has many internal holes, more three-dimensional effects or deeper three-dimensional concavities and convexities.
Items needed to make zinc alloy medals
Zinc alloy medals are made by High pressure zinc alloy medal die casting machine. Next, let’s take a look at the necessary items for making zinc alloy medals.
Hot chamber die casting machine
Hot chamber die-casting machines are mostly used for the production of thin-walled die-casting parts, and are suitable for die-casting low-melting-point non-ferrous alloy parts such as zinc and lead.
Zinc alloy medals Mold
Create or obtain a mold that matches the desired shape and design of the medal. It is worth noting that the number of cavities in the mold is related to the output and quality of the required medals.
One of the difficulties in making zinc alloy medals is the carving around the medals, and the other is the smoothness of the mirror in the middle of the medals.
The smoother the mirror surface, the higher the difficulty of the process. Because the metal raw material itself is rough, the mirror effect is very important for later laser engraving and other requirements. Therefore, in order to present a full mirror effect, when making zinc alloy medals, you can choose a larger hot chamber die-casting machine or reduce the number of cavities in the mold.
Here is a case of machine selection: the production process of customized zinc alloy medals
Take this round medal as an example:
Product raw materials: zinc alloy
Weight: 33.4g
thickness:minimum 1.3-1.4mm
Optional machine: HCD-90H
The solution that pursues output: 4 cavities, 90 tons can be made into products, but the mirror effect cannot be guaranteed. If you need mirror effect, you can choose a larger machine.
A plan that pursues quality: the products made by the 2-cavity. 90-ton hot chamber die-casting machine are not only full but also have a mirror effect.
Auxiliary machines
In addition to the main equipment and items mentioned earlier. There are also some auxiliary machines and tools that can be used to make zinc alloy medals. These auxiliary machines assist in various stages of the production process and increase efficiency. The following are some auxiliary machinery and tools commonly used in zinc alloy medal production:
Hot Chamber Burner: The burner is used to melt the zinc alloy before transferring it to the hot chamber die casting machine. The furnace provides a controlled and efficient heating environment for molten alloys. There are different varieties such as diesel stoves, natural gas stoves, and electric stoves.
(Hot chamber machine gas stove)
Shot blasting machine: Shot blasting machine cleans the surface of cast medals by propelling fine abrasive particles at high speed. This process removes any remaining impurities, scale or oxides from the surface, preparing it for further finishing or plating processes.
Hot chamber pick-up and spray all-in-one machine: Its function is that the robot automatically opens the mold to pick up the parts after the die-casting is completed. After taking out the parts, it automatically sprays the release agent and blows away the water vapor on the mold surface. Its advantage is that it avoids manual operation, not only has high work efficiency, but also improves the working environment.
Edge Trimmer: Used to remove excess material to obtain clean, precise edges for cast medals. Helps improve the overall appearance and quality of the medal.
In addition to the four auxiliary machines mentioned above. There are also mold temperature control machines, automatic conveyor belts, etc. Which can improve production efficiency and quality during the production process.
