Extrusion Contract Manufacturers in Canada

Extrusion contract manufacturing in Canada

A Canadian extrusion contract manufacturer converts aluminum billets or plastic compound into continuous profiles of your cross-section, then cuts, machines, finishes, and ships finished parts or sub-assemblies. The scope ranges from raw extrusion (a metre-cut stick) to complete extruded and fabricated parts with drilled and tapped holes, milled pockets, anodize, and assembly hardware.

This page covers the extrusion process within Canadian contract manufacturing. For the broader evaluation framework, start with the contract manufacturing in Canada pillar. For CNC machining of extruded profiles, see CNC contract manufacturing in Canada.

Aluminum extrusion: the Canadian market

Canada has a fully integrated aluminum extrusion supply chain, from the primary smelters (Rio Tinto Aluminium in Quebec is one of the world’s largest) through billet supply to profile extrusion and finishing. The domestic aluminum supply means Canadian extruders have short, predictable billet lead times and, for CUSMA-qualifying programs, duty-free access to the US market.

Alloy selection. 6063 is the standard architectural and anodize-grade alloy. Its smooth extrudability produces sharp corners and fine features in complex dies. 6061 is used where strength, machinability, and weldability matter more than extrusion detail; tolerances are looser and surface finish coarser than 6063. 6005A is a structural compromise between the two, common for transportation and solar framing applications. 7000-series alloys (7005, 7075) can be extruded for high-strength structural applications but require tighter press control and slower speeds.

Profile types:

• Solid profiles. No enclosed voids. The simplest die design and lowest tooling cost. Examples: angles, channels, T-slots, bars, custom shapes.
• Hollow profiles (tubes). One enclosed void. Requires a more complex die with a mandrel. Examples: square tubes, round tubes, structural tubes.
• Semi-hollow profiles. A profile with a high ratio of tongue depth to gap opening, technically open but die-cutting is similar to hollow. Common for heat sinks and architectural shapes.
• Multi-void profiles. Curtain wall mullions, solar panel frames, and heat exchangers with multiple internal passages.

Heat sink extrusion. A major application of Canadian aluminum extrusion is thermal management. Pin-fin and comb-fin heat sinks for power electronics, LED lighting, and industrial drives are extruded from 6063, then CNC-machined for mounting features, and optionally anodized for corrosion resistance and emissivity.

Plastic extrusion in Canada

Plastic extrusion is a complementary process for profiles that need electrical insulation, chemical resistance, lower weight, or non-conductive properties.

• PVC (rigid and flexible): the highest-volume plastic extrusion. Rigid for pipe and fittings; flexible for jacketing, trim, and edge protection.
• HDPE and UHMW-PE: pipe, wear strips, dock fendering, and structural profiles in corrosive or abrasive environments.
• Polycarbonate: clear and opaque profiles for light guides, machine guards, and glazing.
• PVDF and PTFE: chemical-resistant tubing and profiles for pharmaceutical, semiconductor, and chemical processing applications.
• PEEK and specialty compounds: high-performance plastic profiles for medical and aerospace applications where strength, temperature resistance, and biocompatibility are required.

Canadian plastic extrusion contract manufacturers are found in Ontario (GTA), Quebec (South Shore), and British Columbia, with most serving regional industrial, construction, and OEM markets.

Secondary operations at a Canadian extrusion contract manufacturer

The difference between a raw extrusion supplier and a contract manufacturer is secondary operations capability:

A contract manufacturer quoting your extruded part should price raw extrusion, secondary machining, and finish as a single unit price delivered to your dock.

Regional extrusion capacity in Canada

• Ontario. The largest cluster. Extruders in Brampton, Mississauga, Hamilton, and the Kitchener-Waterloo corridor serve automotive, construction, solar, and industrial markets. Several GTA shops carry both extrusion and CNC machining under one roof. See contract manufacturers in Toronto.
• Quebec. Strong in aluminum extrusion adjacent to the primary smelting base. South Shore (Longueuil) and Laurentides-area shops serve aerospace, transportation, and construction. See contract manufacturers in Montreal.
• British Columbia. Construction, architectural, and marine aluminum. Several BC shops serve the residential and commercial window and door market.
• Alberta. Structural and industrial aluminum extrusion for energy, agriculture, and construction. See contract manufacturers in Calgary.

How to spec a Canadian extrusion RFQ

1. Profile cross-section drawing (2D DXF or PDF) with all dimensions and tolerances. Include inside corner radii (sharp internal corners are not extrudable).
2. Alloy and temper (6063-T5, 6061-T6, etc.).
3. Length and tolerance (±1 mm for saw-cut; tighter requires CNC sawing).
4. Annual volume in kg or linear metres.
5. Finish requirement (mill finish, anodize spec, powder coat colour).
6. Secondary operations (holes, slots, threads, assembly features).
7. Quality requirement (ISO 9001 or applicable spec; dimensional inspection level).
