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: Injection molding in Canada 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. Parts then run from a few cents to a few dollars each. Below roughly 2,000 to 5,000 parts, 3D printing or CNC machining usually beats molding on total cost. 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 |
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.
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. It makes hundreds to a few thousand parts so you can sell before committing to a hardened tool.
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.
