Overview

Design & Prototyping.

Prototyping at SMS isn't a separate process — it's the same equipment, the same fabricator, and the same tolerances we use for production runs at our Brampton shop. The prototype you validate is functionally identical to the part you'll order at scale, because the path from CAD to first-article uses the same workflow as the 100th part.

What it's used for

Design validation on new products, fit-check parts before committing to production tooling, prove-out parts for a customer demo, single-piece replacements for legacy equipment, and short-run market tests. Often paired with DFM (design-for-manufacturability) review where we suggest changes that improve cost or producibility before the part goes to production.

Why people use it

No tooling, no minimum order, no setup penalty for low volume. The prototype runs at the per-piece price you'd see on production-of-ten — so a designer can iterate three or four versions in a week without committing budget. Programs and material certs stay on file; when the design freezes, production picks up where prototyping ended.

What we hold to

Same equipment, same fabricators, same tolerances as production. ±0.005″ on laser-cut features, ±0.5° on bends, ±0.001″ on machined surfaces. DFM feedback returned with the quote. CAD-to-quote turnaround inside one business day on most part families.

Machine & Material

Same Machine, Single Piece.

Prototypes run on the same L3050, Amada brake, and DMV-400 mill we use for production. ±0.005″ cut, ±0.5° bend, ±0.001″ machined — production tolerances on a one-off. Below: every material we prototype in.

Workflow

From Sketch to Sample.

A prototype touches five hands between your concept and the inspection bench. Here's exactly what happens — and where it happens — inside the shop.

Talk to a Fabricator

Send Concept

CAD file, hand sketch, sample part, or photo. Whatever you have. If you don't have CAD, we'll create it from your concept and send back for review.

DFM Review + Quote

We review the design for manufacturability, flag issues, suggest alternatives, and quote — all included with no obligation. You see the manufacturing trade-offs before you spend a dollar.

Material + Process Selection

We match material grade, process (laser vs. punch, MIG vs. TIG), and tolerance level to the prototype's actual purpose — engineering validation needs production-equivalent material; aesthetic samples may not.

Build + Inspect

Prototype built using production-equivalent process. First-article inspection on every dimension that matters. Photos and inspection records sent before shipping.

Iterate or Scale

Iterate to the next revision (fast turnaround, no tooling cost) or scale to production at the same shop, same setup. No re-quoting, no new vendor.

Recent Work

Off the Bench.

Recent prototype work — machined precision components, welded test assemblies, investor samples, pre-production pilot runs. Built on production equipment so what you test is what you'll get at volume.

Where Buyers Get Stuck

What's Slowing Your Decision?

Three worries we hear from buyers iterating their first-article. Here's what each one sounds like — and the honest reply, with the proof.

Three Worries

Worry 01

Worry

“I keep hitting 50-piece minimums and 8-week lead times on prototype quotes.”

The Honest Reply

Single-piece prototypes are welcome. No minimum order, no tooling cost, no setup fee added after the quote. Free DFM feedback comes with every quote so the design improves with each iteration — and most simple prototypes ship inside a week.

Why You Can Trust This

Single-piece prototypes — no minimum order, no tooling cost
Free DFM feedback so the design improves with each iteration
Fast turnaround — most simple prototypes ship in days

Worry 02

Worry

“When the prototype is built on different equipment than production, the parts never quite match.”

The Honest Reply

Same machines, same materials, same tolerances. Prototype on the L3050 and Amada brake, then run production on the same equipment once the design is locked. Material certs are available for traceability, and the handoff from prototype to production happens on the same shop floor.

Why You Can Trust This

Production-equivalent process — same machines, materials, tolerances
Material certs available for traceability requirements
Smooth transition to production — same shop, same setup

Worry 03

Worry

“OEM discontinued my part. All I have is a worn original.”

The Honest Reply

Send the sample, a photo, or a rough sketch. We reverse-engineer to drawing, match steel grade and finish to the original, and ship a single replacement part. No minimum, no tooling fee. Repeat orders cut from the same file three years later.

Single-piece replacement — no minimum order, no tooling
Material match (steel grade, finish) to the original

As few as one. There's no minimum order. We handle single parts, small batches of 5–50, and pre-production pilot runs of 100+ on the same equipment.

Yes — prototypes are made on the same CNC laser, press brake, and machining equipment we use for production runs. Materials, tolerances, and processes are identical. The part you test is the part you'll get at volume.

Simple prototypes ship in 3–5 working days depending on material availability and current shop load. Complex multi-process prototypes (cut + bend + weld + mill) may take 7–10 days. We commit to a delivery date in the quote.

On every quote, free of charge. We flag features that won't manufacture cleanly, suggest alternatives that hit the same design intent, and explain cost trade-offs. Better to fix it on the screen than at the laser.

Yes — same shop, same setup. When your prototype is approved, we scale to production volume without re-quoting or finding a new vendor. The setup, programming, and inspection process are already documented and ready to run at scale.

Both. Many prototype customers across the Greater Toronto Area pick up parts directly at our Brampton shop on Bramsteele Road for fast iteration. We also ship across Ontario — usually within 3–5 working days for simple prototypes, longer for multi-process work. Same-day quotes from your CAD file or sketch.
