The custom medal production process includes designing the medal, choosing zinc alloy, creating a mold, and casting, polishing,etc.
Recognizing people for extraordinary merit or outstanding work by awarding medals and badges is an ancient practice that is often used today to commemorate special events or achievements. We offer the production process of customized zinc alloy medals. Such as sports competitions, academic awards, military milestones, corporate awards, etc. In addition to this, medals and badges can be used for fundraising or as promotional items.
Custom medals can be designed as one-of-a-kind items or as repeatable designs for a range of events. With the option to customize each medal with the recipient’s name, date or other information. Making it a suitable choice for both personal and business use.
Medals are often made from zinc alloy 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 production process of zinc alloy medals.
Custom medal production process
Prepare drawings
Create or receive design artwork for the medal, including required shape, size, logo, text and any other details.
Create using graphic design software or draw by hand and then digitize.
Mold making
According to the design drawings, create a mold to shape the medal.
Molds are 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 medals that need to be produced daily.
Zinc alloy castings
According to the specific requirements of zinc alloy and the design of the medal. Set the injection pressure, injection speed, temperature control and other machine parameters of the hot chamber die casting 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 die-casting 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 medals are trimmed. Then they are ground, polished, and sanded to achieve a smooth and shiny surface.
Color transfer and spraying
The polished zinc alloy medal can be colored and spray-painted according to the design requirements to add color, texture and protective layer. To enhance the appearance and durability of the medal.
The difficulty of making zinc alloy medals mainly depends on the complexity of the engraving around the medals and the smoothness of the mirror surface 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 relatively rough, the mirror effect is very important for the later laser engraving and other requirements. So 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.
