What injection molding actually costs in Canada (tool plus parts)
Injection molding is two costs, the tool and the parts. Real 2026 tooling and per-part ranges, the break-even against 3D printing and machining, and how to quote it.
Quick answer (CAD, as of November 2026): Injection molding is two numbers, not one. Tooling runs roughly $3,000 to $12,000 for a simple aluminum bridge tool and $15,000 to $100,000 or more for a hardened multi-cavity production tool. For a published Canadian anchor, molder Gold Labs lists starting mold prices of $3,500 CAD for aluminum and $5,000 CAD for plastic tooling. Parts then run from a few cents to a few dollars each. The break-even against 3D printing or CNC machining depends on the part: a simple part can cross into molding's favour at a few hundred pieces, a complex or large one not until a few thousand. Molding wins on volume.
The mistake we see most: a startup pays for a hardened production tool to make 500 parts. That is a capital expense chasing a prototype problem.
The two costs
The tool is a machined steel or aluminum mould, a one-time and often large cost. The part price is what each shot costs once the tool exists, driven by resin, cycle time and cavity count. Quote them together, because a low part price on an expensive tool can still be the wrong total.
| Tooling type | Typical cost | Best for |
|---|---|---|
| Aluminum bridge tool | $3,000 to $12,000 | Hundreds to a few thousand parts, market testing |
| Single-cavity steel | $10,000 to $30,000 | Steady mid-volume production |
| Hardened multi-cavity | $30,000 to $100,000+ | High volume, tight cycle-time economics |
| Per part (after tooling) | Cents to a few dollars | Driven by resin, size and cycle |
Published Canadian anchor: molder Gold Labs lists starting mold prices of $3,500 CAD for aluminum and $5,000 CAD for plastic injection tooling, with the mold fee credited back once production reaches 500,000 units. Treat those as starting points, not quotes. Your tool price moves with cavity count and part complexity (below), and most molders do not post prices at all, so a STEP file gets you a real number.
The break-even math
Add the tool cost, divide by your volume, add the part price. A $20,000 tool over 1,000 parts is $20 per part before the resin. The same tool over 100,000 parts is $0.20. That is why molding is a volume play. For low volume, 3D printing has no tooling cost, and machining is often cheaper per part into the hundreds. Most of Canada's molders sit in Ontario's plastics belt around Toronto and Kitchener.
Where the tooling number moves
Cavity count (more cavities, more tool, cheaper parts), part complexity (undercuts, side actions and threads all add), tolerance, and resin (glass-filled and engineering resins wear tools faster). A medical part under ISO 13485 also carries validation and documentation cost that a bracket does not.
Do not overbuy the tool
The molder who quotes tooling without asking your annual volume is quoting a number, not your number. If you are testing a market, ask for aluminum bridge tooling. You can cut a hardened production tool once the part sells. Paying for a 500,000-shot tool to validate demand is how a prototype eats a seed round.
Importing a tool or parts: the landed cost
A quote from a US or offshore molder is not what you pay. On import into Canada you add the 5% federal GST on the value of the goods, plus any provincial sales tax (PST, or HST in the provinces that blend the two), plus any customs duty that applies to the part's tariff classification. Many finished plastic parts and tools cross from the United States duty-free when they qualify under CUSMA rules of origin, but that is classification-specific, so confirm the HS code rather than assume. One thing to ignore: Canada has no VAT, so a landed-cost tool that bills you a 20% "VAT" on a Canadian import is using the wrong country's tax. Freight, brokerage and currency conversion stack on top of all of it. A Canadian molder quotes in CAD with none of that attached, which is part of why the gap to an offshore tool is narrower than the sticker suggests. The detail is in our guide on reshoring to Canada and the current tariff picture.
What to send for a quote
A STEP model, your resin or performance requirement, expected annual and total volume, and any certification needs. Send it once and request quotes from Canadian molders, and we match you to shops sized for your run.
FAQ
Why is injection molding tooling so expensive?
The tool is a precision-machined mould that has to survive thousands to millions of cycles. That machining and hardening is the cost, and it is why molding only pays off at volume.
How many parts before injection molding is worth it?
Roughly 2,000 to 5,000 as a rule of thumb. Below that, 3D printing or machining usually wins on total cost. The exact break-even depends on part size and tool complexity.
What is bridge tooling?
A cheaper aluminum mould that bridges you from prototype to production. Canadian molder ProtoFix defines it as aluminum molds for initial runs of roughly 100 to 1,000 parts, against hardened steel molds built for high-volume, long-life production. Use a bridge tool to sell before committing to a hardened one.
How do I reduce molding cost?
Simplify the part (fewer undercuts and side actions), pick a standard resin, and right-size the tool to your real volume. Multi-cavity tools lower part price but raise tool cost, so match them to demand.
Is molding cheaper than 3D printing?
At volume, yes, by a wide margin. At low volume, no, because printing has no tooling cost. The crossover is usually in the low thousands of parts.
