Overview
Pearson provides access to precision UHMW machining for packaging, food-processing, and material-handling applications. Some work is completed at our Ontario facility; other projects run through vetted Canadian partners. We coordinate sourcing, QA, and logistics end-to-end for consistent results.
Quick Specs
| Material | Wear / Friction | Dimensional Stability | Notes |
|---|---|---|---|
| UHMW-PE | Excellent wear; very low friction | Moderate (may relax post-machining) | Great for guides/liners; food-contact grades |
| Acetal (Delrin®) | Good wear; low friction | High (stiffer; holds tolerance well) | Precision gears, bushings, fixtures |
| Nylon 6/66 | Good wear; low friction | Medium (absorbs moisture) | Higher strength; consider humidity effects |
Service temperature for general-purpose UHMW is typically up to ~82 °C / 180 °F; plan clearances for thermal expansion.
Our UHMW Capabilities
Whether machined in-house or through our Canadian supplier network, Pearson offers:
- CNC Milling: slotting, profiling, pocketing & surfacing of UHMW sheets & blocks
- Turning: bushings, rollers, guides & wear sleeves
- Drilling & Threading: burr-controlled holes & threads in soft material
- Slotting & Boring: keyed slots, bearing fits & through-holes
- Manual Machining: trimming, drilling & custom one-off mods
- Prototyping: fast one-off parts for fit testing & development
- Edge Prep: chamfering & deburring for user-safe, ready-to-install parts
Benefits of UHMW
- Ultra-low friction for long wear life
- Excellent abrasion & impact resistance
- Food-contact grades available; low moisture absorption
- Good chemical resistance & vibration damping
- Lightweight & corrosion-proof in wet environments
Our Equipment
We use the following equipment in-house and coordinate with partners who specialize in UHMW machining:
- 3-axis & 4-axis CNC mills with plastic-specific tooling
- Manual knee mills & turret lathes for small runs
- Precision drill presses & tapping rigs with soft-material chucks
- Boring bars & reamers optimized for UHMW
- Air-blast/mist cooling & chip evacuation systems
- Deburring & polishing stations for final finish
Common UHMW Applications
- Conveyor wear strips, chain guides & rails
- Food-grade cutting boards, liners & star wheels
- Packaging chutes, slides & product handling
- Bearing surfaces, slide blocks & wear pads
- Impact buffers & vibration dampeners
UHMW FAQ
What tolerances can you hold on UHMW parts?
Typical production targets are around ±0.002″ (±0.05 mm) on critical features, subject to geometry and setup. UHMW can “relax” slightly after machining, so we plan process steps to stabilize dimensions.
Is UHMW suitable for food-grade applications?
Yes — FDA/USDA-compliant UHMW grades are available. We machine food-contact plastics in a dedicated handling area and coordinate with partners as needed.
How do you control heat buildup when machining UHMW?
We use sharp tooling, high chip-evacuation rates, air or light mist cooling, and conservative chip loads to avoid melting and edge burring.
What maximum sizes can you handle?
In-house we typically handle up to ~12″ thick and 96″ long. Larger parts are coordinated through our Canadian partner network.
Is this manufactured in-house?
Some UHMW parts are machined in-house at our Ontario facility; others run through vetted Canadian partners. We coordinate sourcing, QA, and logistics end-to-end.
