OEM Diecast Cars: Real Cost, Tooling and Timeline
An OEM diecast car is a model built to your design under your brand. It is also the product of four clocks that start at different times. Design, licensing, tooling and production.
Most guides collapse those into one timeline and quote 60 to 75 days. That figure is real for one case only — a stock model with your logo added. A new body takes four to seven months before the first unit ships.
This page sets out what each stage of OEM diecast car production actually takes, what it costs, and where projects fail. It also covers the part almost every supplier page skips: the licence. If you are new to the product, what diecast cars are explains the material and the casting first.
What Does OEM Diecast Car Manufacturing Actually Mean?
OEM means you own the design and the brand, and a factory builds to your specification. ODM means the factory brings the design and you put your name on it.
For diecast, the difference is the tool. In OEM diecast car manufacturing you pay for the mould and you should own it. In ODM, the factory owns the tool and can sell the same model to your competitor with a different colour.
That single line — who owns the tool — separates a brand from a reseller. Get it in the contract before you pay anything.
| OEM | ODM | |
|---|---|---|
| Who designs | You | Factory |
| Who pays for the mould | You | Factory |
| Who owns the mould | You, if the contract says so | Factory |
| Can the model be resold to others | No, if exclusive | Yes |
| Typical MOQ, new body | 2,000–20,000 | 500–2,000 |
| Control over detail | Full | Limited to their platform |
Do You Need a Licence to Make a Model of a Real Car?
If the model carries a real car’s badge, grille shape or name, plan on needing one. Car makers treat scale replicas as a licensed product category and they enforce it.
The legal picture is more nuanced than suppliers suggest, and it cuts both ways.
Where the brand wins. Customs authorities treat unauthorised replicas as counterfeits. US Customs Directive 2310-010A lists “certain replicas, models, toy cars” as goods that can be seized under 19 CFR 133.21. Seizures happen. Jiuzhou Customs reported one detention of 662 cartons holding 8,796 sets. The declared value was USD 29,600. The models covered Ferrari, Ford, Honda and Jaguar.
Where the model maker wins. In May 2025 the Hamburg Higher Court dismissed Volkswagen’s case against a model car maker (5 U 61/21). The court held that scale models form their own market. An accurate replica does not infringe the design. What it cannot do is suggest it is officially licensed.
Read together, those two facts give you the practical rule.
- Making an accurate model is defensible in court.
- Importing one without a licence is still a customs risk.
- Claiming or implying official approval without one is the part that gets you sued.
Most buyers take the licence. It is cleaner, it gets you the badge artwork, and it opens retail channels that will not touch unlicensed product.
How Much Does a Licence Cost?
Between 4% and 12% of the model’s sales revenue, paid to the car maker.
That range comes from a listed company. Xinghui Model (Shenzhen 300043) told investors in July 2013 that it pays car makers a share of model car sales revenue. The filing puts the rate at “generally 4% to 12%”, settled quarterly, half-yearly or annually.
Two things push you to the top of that range.
- Supercar and luxury brands charge more and often ask for an advance. Budget for the advance, not just the percentage.
- Multi-party licences. A racing car carries the car maker, the team, the sponsor and sometimes the tyre brand. Each one can claim a fee. Racing replicas with several logos can stack well past the single-brand rate.
The licence also comes with work. Artwork approval, a sample sent to the licensor, and packaging that meets their brand rules. Build two to four weeks into the schedule for their review, and expect at least one round of comments.
If you skip the licence, price the risk properly. A detained shipment is not just the goods. It is the freight, the storage, the legal cost, and in some jurisdictions a penalty based on the goods value. Customs also reclassifies such shipments, which is why the duty code matters even when the tariff is zero.
What Does the Mould Really Cost?
Tooling is the line that decides whether an OEM diecast car project is viable. A new mould costs CNY 5,000 to 20,000 for a simple single-cavity tool, about USD 700 to 2,800. A complex multi-cavity tool with moving parts runs CNY 100,000 to 500,000, or USD 14,000 to 70,000.
The figure you see quoted everywhere — USD 300 to 1,000 — is not a mould. It is one of three other things:
- A modification to an existing tool, such as a new logo pocket or a changed grille
- A print plate charge for a new box design
- A sample fee for a prototype
All three are legitimate costs. None of them buys you a new body.
| Tool type | Typical cost | Lead time | Good for |
|---|---|---|---|
| Modification to existing tool | USD 300–1,500 | 10–20 days | Logo, small body change |
| Simple single-cavity, 1:64 | USD 700–2,800 | 45–60 days | First own-brand model |
| Single-cavity, 1:18 with opening parts | USD 5,000–15,000 | 90–120 days | Collector grade |
| Multi-cavity, high volume | USD 14,000–70,000 | 100–150 days | 50,000+ units a year |
Mould life matters here. A zinc diecasting tool runs 200,000 shots or more. If your order is 5,000 units, you are using 2.5% of the tool. The rest is an asset you paid for and should keep.
Ask what happens to the tool after the order. The good answer is: it is marked as yours, stored, and available for your next run. A factory that hesitates on that question is usually planning to reuse it. The factory vetting guide has the questions to ask before the quote.
Who Owns the Mould?
You do, if you paid for it and the contract says so. Both conditions matter.
Three clauses worth having:
1. Ownership. The tool is the buyer’s property on full payment. 2. Marking. The tool carries a discreet buyer mark so it can be identified. 3. Return or destruction. On request, the tool is shipped to the buyer or destroyed, with photos.
A fourth clause that costs nothing and prevents most disputes: no use for third parties. Without it, a factory can run your body for another buyer in a different colour and argue the tool was never exclusively yours.
Chinese law recognises tooling ownership, and a contract clause is enforceable in principle. Enforcement in practice depends on the factory and the local court. The clause is still worth having, and it changes behaviour before any dispute starts.
How Long Does a Custom Diecast Car Take?
Longer than most quotes suggest, and the answer depends on scale. These stage lengths come from GreenLight Collectibles, a US brand that publishes its own process.
| Stage | 1:64 | 1:24 | 1:18 |
|---|---|---|---|
| Clay sculpt and prototype | 45 days | 75 days | 90 days |
| Steel mould cutting | 60 days | 90 days | 120 days |
| First shot, decoration, approval | 15 days | 20 days | 25 days |
| Mass production | 25–30 days | 30–35 days | 35–45 days |
| Total to shipment | 145–150 days | 215–220 days | 270–280 days |
Add 30 to 45 days of ocean freight and you are at five to eleven months.
The 60 to 75 day figure that circulates online is not a lie. It describes a stock model with a new colour and a printed logo. There is no new tool, no licensor review and no clay sculpt in that route.
If a supplier quotes 60 days for a new body, ask which stage they are skipping. Usually it is the licence review, which then shows up as a delay later.
What Does the Whole Project Cost?
Cost structure varies, but the shares are stable. Use these ranges to sanity-check a quote rather than to build one.
| Cost line | Share of FOB | Notes |
|---|---|---|
| Metal and plastic | 25–35% | Zinc price moves; lock it for 6 months if you can |
| Labour and assembly | 20–30% | Hand assembly drives the high end |
| Paint and decoration | 10–15% | Tampo printing and chrome add most |
| Tooling amortisation | 8–12% | Drops as volume rises |
| Packaging | 6–10% | Gift box and acrylic push the top |
| Testing and certification | 1–3% | Higher for a first model |
| Licence | 4–12% | Only if the model carries a real brand |
Two observations that save money.
Paint and decoration is where cheap projects break. A four-colour tampo print on two sides plus chrome trim can add 40% to the decoration line. If your design has a livery, price it before you commit to the artwork.
Testing is a fixed cost per model, not per unit. At 500 units it is a real share of the price. At 20,000 it is noise. This is one more reason small first orders cost more per unit, as the MOQ breakdown shows on the volume curve.
For a first own-brand model at 1:64, 3,000 units is a realistic starting point. Budget USD 12,000 to 18,000 all in. That covers tooling, goods, packaging and testing. It does not cover freight or the licence.
How Do You Control Quality?
With a written standard and a sampling plan, agreed before the first shot.
Ask for AQL sampling to ANSI/ASQ Z1.4, level II, with critical at 0, major at 2.5 and minor at 4.0. That is the common toy-industry setting and it is specific enough to argue about.
| Lot size | Sample size | Major accept | Minor accept |
|---|---|---|---|
| 281–500 | 50 | 3 | 5 |
| 501–1,200 | 80 | 5 | 7 |
| 1,201–3,200 | 125 | 7 | 10 |
Critical defects are zero in every row. For a diecast car those mean sharp edges, loose parts that fit a small-parts cylinder, and anything that fails the drop test.
Three inspection points, not one:
- Pre-production sample. Signed off in the retail packing, with colour measured against your Pantone.
- During production. Check after the paint line, before assembly. Paint faults caught after assembly are scrap.
- Pre-shipment. AQL sampling plus a carton drop test, one carton per pallet.
If the model is for children, the test reports need to be current and to match the age grading on the pack. Cheap reports come from labs that are not accredited, so check who issued them against the lab comparison. The certification requirements cover what changes between a 3+ and a 14+ label, which is a bigger cost swing than most buyers expect.
What Goes Wrong Most Often?
Seven failure modes, in the order they actually happen.
1. No licence, discovered at customs. The most expensive. Goods detained, freight sunk, no recourse to the factory.
2. Incomplete reference material. A supplier working from three photos will invent the rear end. Send orthographic views, wheel detail, interior shots and a colour reference. If you have no CAD, say so early — the factory can build it, but it adds two to three weeks.
3. Mould ownership left vague. Your model appears in another buyer’s catalogue a year later.
4. First sample approved too fast. A resin prototype looks close. The painted metal first shot is where colour drifts. Approve the decorated shot, not the resin.
5. Packaging decided last. Artwork, dieline and print add two to four weeks. Start it in parallel with tooling, not after it.
6. Licence review not in the plan. Two to four weeks, sometimes with a second round. If the licensor asks for a design change after the steel is cut, the mould change is real money.
7. No agreed AQL. “We check every piece” means nothing. Get the standard, the level and the acceptance numbers into the purchase order.
What Should Be in the Contract?
Nine clauses. None of them are unusual, and all of them are cheap to add before signing.
| Clause | What it protects |
|---|---|
| Tooling ownership and marking | Your asset |
| Exclusivity for the model and the market | Your range |
| Licence responsibility, stated for each side | Liability |
| AQL standard and acceptance numbers | Quality |
| Approval gates and who signs | Timeline |
| Packaging artwork deadline | Schedule |
| Late delivery penalty or credit | Delivery |
| Payment schedule tied to milestones | Cash |
| IP indemnity | Recourse |
The IP indemnity line is the one buyers skip and later need. If the factory supplies artwork or a body shape that turns out to infringe, you want the responsibility to sit with them, in writing.
Is OEM Diecast Car Manufacturing Worth It?
Run three numbers before you commit.
Cost per unit against the retail price. A 1:64 model at USD 2.20 landed needs to retail at USD 8 to 10 through a shop, or USD 15 to 20 direct. If your channel cannot support that, the project does not work at any volume.
Tooling against expected sales. A USD 2,100 tool spread over 3,000 units adds USD 0.70 a unit. Spread over 20,000 it adds USD 0.11. If you expect to sell 3,000, the tool is a real cost. Plan a second model on the same body to spread it.
Time against your launch date. Five months for 1:64, nine for 1:18, plus freight. A launch set for a fixed date needs the brief to start five months earlier than most people plan.
Where OEM wins is control. Your body, your colour, your box, your brand, and nobody else selling it. Where it loses is flexibility. You cannot change the model next month, and you cannot test ten designs for the price of one.
If you want to test the market first, buy stock, relabel it and see what sells. Then build. That path costs more per unit and far less per mistake. The wholesale range is the place to start.
FAQ
What is the minimum order for an OEM diecast car? 2,000 to 3,000 units for a new 1:64 body. That is where the tooling amortises to a workable share of the price. A modified existing tool can start at 240 to 500.
Can I make a model of my own car? Yes, and it is a common project. If it is a one-off personal vehicle, you still need the manufacturer’s permission if the badge and body shape are recognisable. Many owners start with a generic body and their own livery, which avoids the licence entirely.
How much does a custom diecast car cost? Tooling USD 700 to 2,800 for a simple 1:64 tool. Unit cost USD 1.50 to 3.50 at volume. A 3,000-unit first project lands near USD 12,000 to 18,000 before freight.
How long does a custom diecast car take? 145 to 150 days for 1:64 and 270 to 280 days for 1:18, measured to the point of shipment. Add sea freight on top. Anyone quoting 60 days for a new body is describing a stock model with a logo.
Do I own the mould? If you paid for it and the contract says so. Ask for ownership, marking, return and a no-third-party-use clause.
What if I do not have 3D files? The factory can build the model from reference material. It adds two to three weeks and a design fee. Send orthographic views and detail photos rather than a handful of press images.
Is a licence always required? For a recognisable production car, in practice yes. The legal position on the design is more forgiving than the customs position on import. Budget 4% to 12% of revenue and treat the advance as part of the cost.
Is OEM diecast car manufacturing possible at 500 units? Yes, at a unit price that carries most of the tooling. A 500-unit run of a new body often costs 2.5 to 3 times the volume price. Consider
