A medal making machine is a special device use to manufacture medals or commemorative medals. It typically using mold casting or embossing techniques. The main function of a medal casting machine is to produce medals with specific designs and qualities by injecting molten metal into molds or forming patterns on metal surfaces through embossing technology.
Medal casting machines can divide into various types. Including hot chamber die-casting machines, cold stamping machines, laser cutting machines, etc., Each type is suitable for different materials and production needs. For example, hot chamber die casting machines are suitable for mass production of low melting point metals such as zinc alloys, and have the characteristics of high efficiency and high precision. The cold stamping machine is suitable for medal production that requires high relief effect. In addition, laser cutting machines can be used for medal making of non-metallic materials such as plastics, resins, etc.

Introduction To Medals
Recognizing people for extraordinary merit or outstanding work by awarding challenge coins, lapel pins, medals, cufflinks, and badges. That is an ancient practice often uses today to commemorate special events or achievements. Such as sports competitions, academic awards, military milestones, corporate awards, etc. In addition to this, zinc alloy medals and badges can use for fundraising or as promotional items.
Customize zinc alloy medals can design 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. Like challenge coins, lapel pins, medals, belt buckles. And also key chains, police badges, dog tags, cufflinks, patches, es, and poker chips. Making it a suitable choice for both personal and business use.
Medal suppliers often make challenge coins, lapel pins, medals, belt buckles, key chains, police badges, dog tags, cufflinks, patches, and poker chips with medal making machines. Because it is cheap, lightweight, and easy to work with. Futhermore, they can decorate 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 medals.
Medal making machine classification
The common types or classifications of medical making machines mainly include the following:
Die Casting Machine
This is the most common equipment for manufacturing metal medals, suitable for mass production of materials such as zinc alloys and copper alloys. It forms medals by injecting molten metal into molds, with advantages such as high efficiency, high precision, and consistency. For example, Haichen’s hot chamber die-casting machine is particularly suitable for the production of zinc alloy medals.
Hot Chamber Die Casting Machine
- Applicable material: Zinc alloy
- Advantages: high pressure, high surface quality, suitable for complex shapes, mass production, low cost.
- Disadvantage: Not suitable for aluminum and magnesium alloys
- Application scenarios: Small batch production of medals, badges, brooches, etc
Cold Chamber Die Casting Machine
- Applicable materials: aluminum, magnesium alloy
- Advantages: Suitable for high melting point metals, high precision
- Disadvantages: High cost, complex equipment
- Application scenarios: Industrial fields such as automotive, electronics, aerospace, etc
Stamping Machine
The stamping machine uses for making preliminary blanks for metal medals. And then forming relief effects on the metal surface through stamping technology. This method is suitable for medals that require high relief effects.
Stamping die: composed of an upper mold and a lower mold, the metal sheet is stamped into the desired shape through mechanical pressure. It suitable for edge treatment and detail carving of medals.
Advantages: High efficiency, suitable for mass production, but high mold cost.
Laser Cutting Machine
Laser cutting machine is uitable for medal making of non-metallic materials. Such as plastic, resin, or wood, capable of achieving high-precision and complex design cutting.
Laser engraving patterns on metal surfaces is suitable for high-precision and complex designs.
Advantages: High degree of automation, high efficiency, suitable for mass production.
Disadvantages: High equipment cost, not suitable for manual carving
Choose which type of machine to make medals?
The advantage of die casting medal maker machine is high pressure. The zinc medal in the high-temperature die casting process under high pressure will have a smoother surface. It’s capable of producing complex zinc components in large quantities. That can save production costs. This process enables you to manufacture thin-walled and lightweight zinc parts.
We recommend a hot chamber die casting machine to make medals. This machine to make medals is a specialized device designed for manufacturing metal challenge coins, lapel pins, medals, cufflinks, and badges.
This machine employs die-casting technology by installing meticulously crafted molds onto the die-casting machine, utilizing stamping techniques to press and shape pre-prepared metal blanks.
The hot chamber die-casting technique is typically used during the zinc die casting process, allowing for superior control over the molten metal flow.
During this process, the furnace is first attached to the die casting machine using a metal feed system (also known as a gooseneck).
Next, the injection mechanism is immersed in a molten metal bath within the furnace. Once the process begins, the plunger is pushed downwards, forcing the metal within the chamber into the die cavity.
Due to zinc’s mechanical properties, zinc die-casting processes are much faster than other materials like aluminum. The end result is a precise die casting component with high-quality finishing. So hot chamber die casting machine is a more suitable machine to make medals.
Medal making process of zinc alloy medal
Design drawings
Create or receive design artwork for the zinc alloy medal, including the 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.
Customize Mold for medal making machine
According to the design drawings, create a mold to shape the zinc medal.
Zinc alloy medals usually made of steel and consist of two halves, the “mold” and the “core”. It fits 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 produce daily.
Zinc alloy medal castings process
According to the specific requirements of the zinc alloy medal and the design of the medal. With setting the injection pressure, injection speed, temperature control. And also with 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. The polished zinc alloy medal can be colored and spray-painted according to the medal suppliers’ design requirements to add color, texture, and a protective layer. To enhance the appearance and durability of the medal.
Gold-plated
By electroplating or chemical gold plating process, a layer of gold is deposited on the surface of the medal to enhance its aesthetics and value.
Advantages: Suitable for high-end medals such as commemorative medals, commercial medals, etc.
Disadvantages: High cost, requiring specialized equipment.
Coloring
Apply colors to the surface of the medal through spraying or printing processes to enhance its visual effect.
Advantages: Suitable for commemorative medals, commercial medals, etc.
Disadvantage: Requires specialized equipment and materials.
Surface treatment
By high-temperature oxidation or chemical treatment, specific colors such as black, gold, etc. are formed on the surface of the medal.
Advantages: Suitable for commemorative medals, commercial medals, etc.
Disadvantage: Requires specialized equipment and materials.
