Buyer’s Guide
“How much does a custom metal keychain cost?” is the question every buyer asks first — and the one no honest factory can answer without seeing your artwork. This page explains exactly which factors move the price, which ones barely matter, and how to compare two quotes that look similar but are not.
A custom metal gift is not a catalogue product. Two keychains of the same size can differ in cost by 40% depending on metal, part weight, number of enamel colours, plating type and packaging. Any supplier who quotes a fixed price before seeing your design is quoting a different product than the one you will receive.
What you can do instead is understand the cost drivers well enough to know which specification changes will save real money — and which will quietly damage the finished piece.
| Factor | Cost impact | What actually changes |
|---|---|---|
| Part weight & metal | High | Zinc alloy, brass and stainless differ in raw cost and machining time. Heavier parts use more metal and cool slower. |
| Forming process | High | Die casting suits 3D shapes; stamping suits flat thin parts; CNC is precise but slow. The right process for your geometry matters more than any other choice. |
| Number of enamel colours | Medium–High | Each colour is a separate dispensing step, cure cycle and inspection point. Reducing six colours to four is a real saving. |
| Plating & finish | Medium | Standard antique brass, nickel or gunmetal are bath-ready. Custom-matched or two-tone finishes add set-up and handling. |
| Packaging | Medium | A polybag costs cents; a printed rigid gift box can cost more than the metal part itself and carries its own MOQ. |
| Order quantity | High | Fixed costs — tooling, set-up, baths — are amortised across more units. See our MOQ guide for how the curve behaves. |
| Tolerance & QC level | Medium | Tight dimensional tolerances and 100% inspection raise labour. Standard commercial tolerance keeps cost down. |
For die-cast parts, a steel mould is cut for your specific shape. That is a one-off charge, separate from unit price, and it is the reason a 500-piece order costs noticeably more per unit than a 5,000-piece one: identical tooling, spread over ten times fewer pieces.
Two things are worth confirming before tooling starts. First, who owns the mould — in most projects it is yours, and the factory keeps it available for reorders. Second, how long it is retained after your order ships, because a lost mould means paying for tooling twice.
If budget is the constraint, ask what existing base shapes the factory already holds. Adapting a logo onto an existing tool can remove the tooling charge entirely.
A lower number is not always a lower cost. Before you choose, confirm that both quotes include the same things:
The fastest way to a firm number is a complete brief. Send these six items and a factory can quote without three rounds of questions:
Send your artwork, quantity and finish. We will quote the tooling, the unit price at three quantity tiers, and tell you which specification changes would bring the cost down — before you commit to anything.

Usually, because raw metal is priced by weight and heavier castings take longer to solidify and finish. But a well-designed hollow or open-back part can look substantial while using less material.
Yes, in three places: quantity, packaging and finish. Moving from a custom printed box to a stock box, or from a custom-matched plating to a standard bath finish, reduces cost without touching the artwork.
Generally no, provided the mould has been retained. This is why tooling ownership and retention period should be agreed in writing before the first order.
Tooling, sampling and bulk production each add time, and plating and enamel cycles depend on complexity. Ask for the full sequence broken into stages rather than a single delivery date.
