Match the process to the product.

Soft and hard enamel are process choices within product families. Review the surface, artwork, structure and intended supply together.

Illustrative recessed soft enamel and smooth hard enamel surface studies

Soft enamel retains recessed colour between raised metal divisions. Hard enamel has a smooth, flush polished surface. Fine lettering, colour boundaries and the proposed finish need review at the intended size.

A shared start.
Four assembly routes.

Product families share manufacturing stages, with individual bodies and assembly requirements. The finishing order depends on the selected process and metal finish.

  1. Artwork & tooling

    Review the artwork and prepare tooling for the agreed design.

One brief.
Several product families.

Start with your artwork, develop an original idea, or adapt a design. Each product still needs a clear version, quantity and supplied scope.

FAQ

Questions across product families.

Product range illustrative reference

Product range

01Which enamel products can we commission?

We manufacture custom pins and badges, keychains, medals and charms for business projects. A pin is defined around wearing and attachment; a keychain around its body, connector and ring; a medal around its body, suspension and ribbon; and a charm around its interface and supplied form. The examples introduce these formats. Each enquiry needs its own artwork and construction review.

02How do we choose the right product family?

Begin with the intended use and what the recipient will receive. Consider whether the object will be worn, carried on keys, presented as an award, or supplied as a component for another accessory. Then define how it attaches and which parts are included. Those decisions identify the family more reliably than shape or colour alone.

03Are the example designs available from stock?

No. The displayed designs are illustrative custom concepts, not stock products or customer case studies. They help describe a brief. Your artwork, size direction, construction, fittings and presentation are reviewed for the project; a reference image is not a confirmed production specification.

Supplied scope illustrative reference

Supplied scope

04Can a charm be supplied as a component rather than a finished accessory?

Yes. The supplied scope can distinguish the enamel body, a selected fitting, assembly and presentation. State which parts you require and who will assemble the final accessory. The hanging hole, connector and adjoining item must be considered together so that a quotation describes the intended delivery rather than an assumed complete product.

05Are soft and hard enamel separate product categories?

They are process choices within product families. Soft enamel typically retains recessed colour between raised metal divisions; hard enamel is polished to a smooth, flush surface. The artwork, intended appearance, structure and finish must be reviewed together. Choosing a surface does not by itself define the complete pin, medal, keychain or charm.

06Which manufacturing stages are completed in your factory?

Our own factory carries out tooling and metal forming, colouring, polishing, plating, assembly, inspection and packing. The route and checks are defined around the selected product and finish. Factory images currently labelled as AI-generated are illustrations of the manufacturing scope; they are not documentary photographs of our premises.

07Can the same brand identity be used across different products?

Yes, a project can develop a shared visual identity across several product families. Each format still needs its own artwork and construction review. A mark that works on a medal may need adjustment for a small pin, and a charm's hanging interface differs from a pin's reverse. Record the design version, supplied scope and quantity separately for each format.

08How should quantities be listed for a multi-product project?

List quantities by product, design and version. State whether each quantity refers to individual pieces or complete sets; for a set, also list the items included. Keep fittings, assembly and packing requirements alongside each line. This prevents a total project quantity from hiding different versions or different supply requirements.

09Will colours look identical across different formats?

Use a common colour reference, but review it against each product's surface, metal finish and sample. The size of a colour area, adjacent metal and viewing conditions can affect its appearance. Record the accepted reference and any product-specific decisions so later reviews do not rely only on photographs or screen colours.

10What should we include in a multi-product brief?

Include the required families, artwork or concept, intended use, size direction, quantity per design or version, and supplied scope. Identify fittings and presentation, the target arrival timing and destination. You can start with an incomplete brief, but mark unresolved points clearly so they can be reviewed before the production scope and schedule are agreed.
