Invent Art, Uxbridge, Ontario

Bring us an idea. We'll help you figure it out.

We design things and make them in our own shop: injection molds and molded parts, machined parts, prototypes, whole products and custom builds. Bring an idea, a drawing or a part that needs fixing. It starts with a conversation.

Where it goes wrong

It is easy to spend a lot before you know it will work.

If you have an idea

Molds are usually made in large facilities or sent overseas. They are big projects, and hard to change once they are made.

A lot of product quotes assume the idea is already proven. You can pay for the whole thing before anyone has tested the one part that might not work.

If you run a business

The problem is different. A small run, an awkward part or a mold repair can be hard to place.

What we do

We design it. We make it.

One shop that designs and makes. Pick the way in that fits what you have.

I have a drawing, an injection mold or a short run.

A part to make, a small run or a tricky feature. We go over the drawing with you and make the part. A mold that needs a repair or a change, or a short run to place. There is no minimum order.

Tooling and parts

We are a design firm.

Design firms already send us overflow work. We work to your files, and your client stays your client.

Prototyping

I have an idea.

A sketch is enough to start. We help you test the uncertain part before you pay for the rest.

Who you work with

We make products too. We know the seat you are in.

The owners run their own product businesses. They have had to make things, package them and sell them. So we will ask about your market, your packaging and why you are making this. All of it goes into a better prototype.

If you already know exactly what you need, we will not make you sit through that. We will check the drawing with you and make the part.

We stay small on purpose. You deal with the same people here.

How it goes

How working with us goes.

01
We talk first
A real conversation, by phone, video or in person. The first one is free.
02
We work out what it needs
For a new idea, that means testing the uncertain part before you pay for the rest. For a drawing you already have, it means going over it with you so the part comes out the way you need it.
03
We make it
Tools, parts and runs, sized to where you are. Your mold is yours once it is paid for. We store client molds between runs and can run yours again when you need more parts. When you outgrow us, we will tell you.

How we work

About us

Scrappy, on purpose.

Invent Art is a design and fabrication shop at 192 Main Street North in Uxbridge, Ontario. Invent Art started in 2014, building a client base in CAD design, unique builds, and laser and CNC wood routing. In 2021 we started working with Colpitts Design, the shop that has made things here since 1992, and it became obvious the two shops would eventually merge as Peter Colpitts worked toward an incredibly well-deserved retirement. In September 2026 we took over operations and moved under one roof, combining two great teams. Everyone who worked here stayed.

We design injection molds for plastic parts and machine them from aluminum in-house. We machine parts, do sinker EDM work and run molds on our own 60-ton and 150-ton presses. Design and cutting happen under one roof, so a change doesn't wait on another company.

Most ideas need something simpler than a big development program. They need a rough version that proves the idea works. We sort out what is already solved, prove what is not, and drop the steps that don't need to be there.

For businesses, we are the shop you call for the small run, the hard part or the repair.

We will help you find out whether your part can be molded, then mold it and make your runs. When your volumes outgrow a small shop, a production molder will serve you better, and we will say so.
