Prototyping
Functional prototypes built from your CAD, designed to carry over into production tooling.
We make functional prototypes for automotive and industrial clients across Ontario: one-off parts for fit checks, small batches for testing, and pilot runs while production tooling is built. Pick the process that matches what you need to learn from the part; rapid prototyping methods compared sets them side by side.
CNC Machined Prototypes

Machined from production metals and engineering plastics, including aluminum and titanium, with 5-axis machining, milling and turning. Best when the prototype has to match the final part's material, strength and tolerances. See CNC machining.
3D Printed Prototypes

Metal and plastic 3D printing for concept models, complex shapes and quick design iterations, with no tooling. See 3D printing.
Carbon Fiber and Composite Prototypes

When the final part will be carbon fiber, prototype it in carbon fiber so you test the real weight, stiffness and finish. Our carbon fiber page covers when carbon fiber suits a part.
Short Runs and Bridge Tooling
Rapid tooling and short-run batches cover pilot builds and early orders while production tooling is made. When volumes grow, the same design moves into production tooling.
Starting Without CAD

Send a sketch or a sample part. Our design service and reverse engineering turn it into a model we can build from.
Recent Work
- Ball screw replacement: a failing ball screw reverse engineered and remade in 4 weeks, against a 12+ week OEM lead time, for about 30% less than the OEM price.
- 7075 aluminum control arm, CNC machined and gold anodized.
- SSD Enclosure 1, our own pre-preg carbon fiber product, from layup to compression molding.
- Porsche 911 harness bar: bent and welded 4130 chromoly or titanium tube, a quick-turn build with M-Tech Racing.

From Prototype to Production
We review each prototype for manufacturability, flag changes that cut cost or risk, and carry the same files into production tooling, so the step to production doesn't start from scratch. Before you send a part, read design features that add cost and what to send, then use the form below.
