Overview

We specialize in machining engineering plastics—UHMW, Delrin, Nylon, PTFE, and more. Whether your job is completed in-house or through our trusted Canadian supplier network, we ensure clean edges, tight tolerances, and proper handling for food-grade, chemical-resistant, and custom plastic components.

Our Plastic Capabilities

Our plastic machining capabilities — performed in-house or through our local manufacturing partners — include:

CNC Milling: high-speed milling, slotting & profiling of complex plastic parts
Manual Machining: trimming, rework & low-volume specialty jobs
Turning: precision bushings, caps, guides & washers in plastic stock
Slotting & Boring: burr-free holes & keyed slots in flexible materials
Prototyping: fast one-off runs for R&D & functional testing
Assembly & Finishing: deburring, chamfering & ready-to-install components

Why Plastic?

Lightweight & corrosion-resistant for harsh environments
Low friction & wear resistance in moving assemblies
Excellent chemical & food-safe options available
Tight tolerances and clean edges on soft materials
Minimal thermal deformation with proper feeds & coolant

Our Equipment

Our team or trusted Canadian partners use the following plastic-optimized equipment:

3-axis & 4-axis CNC mills with plastic-specific tooling
Manual knee mills & turning centers for small runs
Precision drill presses & tapping rigs with low-backlash chucks
Boring bars & reamers optimized for plastics
Air-blast chip control for clean machining
Deburring & polishing stations for smooth finishes

Plastics We Commonly Machine

UHMW – ultra-high molecular weight polyethylene for wear parts
Delrin (Acetal) – stiff, low-moisture, precision components
Nylon (PA6/PA66) – strong, resilient wear parts
PTFE (Teflon) – chemical-resistant, low-friction applications
HDPE, PVC, Polycarbonate & specialty blends available

Typical Applications

Food-processing guides & wear strips
Medical device housings & insulators
Chemical handling valves & seals
Lightweight structural components & enclosures
Custom jigs, fixtures & low-friction bearings

Plastic Machining FAQ

What tolerances can you hold in plastic?

We routinely achieve ±0.002″ (±0.05 mm) on critical plastic features, with tighter tolerances on request.

Do you machine food-safe plastics?

Yes—UHMW, PTFE, and other FDA-compliant materials are machined in a dedicated area to prevent cross-contamination.

How do you control heat when machining plastics?

We use optimized feeds, speeds, and coolant strategies to minimize thermal distortion and ensure smooth finishes.

Can you bond or assemble plastic parts?

We offer adhesive bonding and ultrasonic welding for many engineered plastics, plus mechanical fastening prep.

Is this manufactured in-house?

Some plastic machining is completed at our Ontario shop, while other jobs are fulfilled through trusted Canadian manufacturing partners. Pearson oversees every stage — from sourcing and machining to quality control and delivery.
