The process of mould creation is a critical phase in the manufacturing process. It involves precision engineering and advanced technology to ensure that the final product accurately reflects the intended design. Here's a detailed look at this process:
1) Preparation for Mould Design
The finalised keyring design is translated into a mould design. This involves converting the 2D digital design into a 3D model that will be used to guide the mould-making process.
2) CNC (Computer Numerical Control) Machining
The 3D mould design is input into a CNC machine's software. CNC machining involves the use of computerised controls to manage the tools and machinery required for manufacturing.
A suitable metal block is chosen for the mould. The choice of metal for the mould depends on factors such as the type of metal used for the keyring, the level of detail required, and the expected production volume.
3) Carving the Design
The CNC machine uses cutting tools to carve the design into the metal block. This involves removing metal from the block to create a cavity that matches the shape and details of the keyring design.
The cutting tools are controlled with high precision, often down to fractions of a millimetre, to ensure that the cavity accurately reflects the design. For more complex designs, the machine may use different tools or multiple passes to achieve the required level of detail.
4) Finishing the Mould
After the initial carving, the mould undergoes a smoothing and polishing process. This is crucial to ensure the final finish is high-quality with no sharp edges or unwanted marks.
The completed mould is then inspected for accuracy and quality. This may involve measuring the mould to ensure it matches the design specifications and checking the surface finish.
5) Testing the Mould
Before full-scale production begins, the mould is often used to produce a small number of keyring prototypes. This is an important step to verify that the mould produced ones that meet the expected standards in terms of appearance and quality.
If any issues are identified during the prototype production, the mould may need to be modified. This could involve additional CNC machining to adjust the mould or further polishing to refine the surface.
6) Preparing for Mass Production
Once the mould is finalised and tested, it is assembled into the larger production machinery, such as a die-casting or stamping press, ready for mass production of the keyrings.
Die-Casting or Stamping
![](https://static-promotionsonly.com.au/blog/images/die-casting-100.jpg)
The manufacturing process often involves either die-casting or stamping, depending on the complexity of the design and the properties of the metal used. Both processes have distinct technical aspects that make them suitable for different types of keyring designs.
1) Die-Casting Process
Preparation of the Die: The die, which is essentially a mould, is created as per the finalised keyring design. It consists of two halves that come together to form the cavity into which the metal is injected.
The die surfaces are treated or coated to facilitate the easy release of the cast part and to extend the life of the die.
Melting the Metal: Metal (such as zinc, aluminium, or magnesium alloys) is melted in a furnace at a specific temperature. The choice of metal depends on factors like strength, weight, and appearance.
Injection into the Die: The molten metal is injected into the die under high pressure. This pressure is maintained until the metal solidifies. The high pressure ensures that the metal fills every part of the die, capturing all the intricate details of the design.
Cooling and Solidification: After the metal is injected, it is allowed to cool and solidify in the die. The cooling process must be controlled to prevent defects in the final product.
Ejection and Trimming: Once the metal has solidified, the die is opened, and the cast keyring is ejected. The excess metal, known as flash, is trimmed off.
Post-Processing: The cast keyrings may undergo additional processes such as polishing, plating, or painting, depending on the design requirements.
2) Stamping Process
Preparation of the Stamp Die: Similar to die-casting, stamping requires a die, which in this case is a stamp that will press the metal into the desired shape. The die is crafted from durable materials to withstand the pressure of stamping.
Selection of Metal Sheet: A flat sheet of metal, like stainless steel, brass, or copper, is selected based on the desired properties of the final product.
High-Pressure Stamping: The metal sheet is placed in the press, and the stamp die is brought down with high pressure. This pressure forces the metal sheet to conform to the shape of the die. For more complex designs, a series of stamping operations may be required.
Trimming and Cleaning: Excess material from the stamped metal is trimmed off, and the keyrings are cleaned to remove any oils or residues from the stamping process.
Post-Processing: As with die-casting, they may also undergo additional finishing processes such as polishing, engraving, or coating.
Both die-casting and stamping are effective methods for producing metal keyrings, each with its specific technical considerations. Die-casting is more suitable for complex, intricate designs and for metals with a lower melting point, while stamping is preferred for simpler designs and for metals that are more malleable and can be easily shaped under pressure. The choice between these two methods depends on the design, the required physical properties, and the production volume.
5. Detailing and Finishing

Mechanical engraving, which uses a rotating cutting tool, is another option, particularly for deeper engravings.
Embossing Process: Embossing creates a raised design on the surface. It involves pressing the metal between a male and female die to form a three-dimensional design. This technique is often used for larger, simpler designs.
Adding Customisation: Both engraving and embossing are key for personalisation, allowing for the addition of logos, text, and intricate patterns that reflect the brand or message the keyring is intended to convey.
3) Plating and Coating
Plating Options: Plating involves covering the keyring with a thin layer of another metal. Common choices include nickel, chrome, and gold. Each type of plating offers different aesthetic and protective qualities. For example, chrome plating gives a highly reflective finish, while gold plating adds a luxurious look.
Coating for Protection: Coatings are applied to protect it from elements like oxidation and wear. This could include clear coatings, lacquers, or specialised protective layers that enhance durability and resistance to tarnishing.
Enhancing Aesthetics and Longevity: Both plating and coating not only enhance the appearance but also extend its lifespan by providing a protective barrier against environmental factors.
4) Additional Considerations
Consistency in Finishing: Quality control during the finishing process is crucial to ensure that each keyring maintains consistency in appearance and meets the set quality standards.
