Overview
Precision plastics demand more than tooling — they require material knowledge, stable processes, and careful finishing. Pearson Manufacturing supports polymer-focused programs with CNC machining, tooling coordination, molding, and assembly — fulfilled either at our Ontario facility or via trusted Canadian partners. We manage documentation, resin traceability, and logistics so your parts meet performance and cosmetic requirements.

Quick Specs
Workstream | Best For | Speed | Notes |
---|---|---|---|
Prototype / Dev | CNC-cut parts & fit/functional models | Fast | Quick-turn + DFM feedback; material trials |
Bridge Tooling | Low-volume molded runs | Medium | Aluminum tools; rapid iterations; resin traceability |
Production Molding | Validated tooling & volume parts | Medium | Process windows, QC plan, PPAP on request |
Assembly & Kitting | Ready-to-install subassemblies | Fast | Ultrasonic weld, inserts, labels/packaging |
Capabilities We Provide Access To
- High-precision CNC machining of PEEK, Delrin, PTFE, Nylon, Ultem, and acrylics
- Injection mold tool design, fabrication, sampling, and validation (by routing)
- Insert & overmolding with brass/SS inserts and multi-material combinations
- Secondary finishing: deburring, ultrasonic cleaning, vapor/polish finishing for optics
- Ultrasonic welding, heat staking, adhesive bonding, and mechanical assembly
- DFM reviews, material selection support, and mold-flow simulation coordination
- Inspection packages: CMM/vision, surface finish results, ballooned reports, lot traceability
DFM & Standards Tips
- Favor uniform wall thickness; ribs ~40–60% of nominal wall to minimize sink/warp.
- Apply draft on molded faces (typ. 1–2°; more for textured surfaces). Call out critical no-draft zones explicitly.
- Use generous radii at internal corners (≥0.5–1.0 mm) and avoid sharp transitions from thin→thick sections.
- Prefer metal inserts for durable threads; if plastic threads are required, specify class/tolerance and engagement.
- Gate location should consider knit lines, aesthetics, and functional loads; specify cosmetic-critical surfaces.
- For CNC plastics, request edge breaks (e.g., 0.1–0.3 mm) and specify any optical faces requiring protection/polish.
- Declare cleanliness/packaging (bag/label/ESD) and resin lot traceability requirements on the RFQ.
We’ll review your model/drawing, resin & cosmetic specs, and documentation list, then confirm achievable tolerances and the right routing (in-house or partner) before kickoff.
Why Partner with Pearson?
- Hybrid routing for capability, cost, and schedule — managed under one QA umbrella
- One partner from prototype CNC to validated tooling and production molding
- Material and process guidance for demanding environments (heat, chemical, wear)
- Traceable documentation and inspection data with optional PPAP/FAIR by request
- Consolidated quoting, build oversight, assembly, and logistics through a single contact
Equipment Used In-House or By Our Partners
- 5-axis CNC machines with polymer-optimized tooling and workholding
- Injection molding presses (≈10–300 ton) with insert & overmold capability (by routing)
- Dryers/dehumidifiers, mold temperature controllers, and hot runners (by routing)
- Ultrasonic welders, heat-stake stations, and adhesive bonding fixtures
- Vapor polishing for PMMA and optical finishing benches (by routing)
- CMMs and video/optical inspection; torque/pressure feedback for assembly
Typical Plastics Applications
- Medical-grade PEEK/Ultem housings and covers (non-implant)
- Precision bushings, bearings, wear pads, and guides
- Overmolded sensor bodies, connectors, and strain-relief boots
- Custom cable guides, clips, and electrical brackets
- Insulative polymer shields, panels, and enclosures
- Cleanroom-compatible trays, totes, and fixture plates
Plastics FAQs
Are parts made in-house?
Select polymer components are produced at our Ontario facility; tooling and molding are coordinated via vetted Canadian partners. We manage quoting, QA, and logistics end-to-end.
Do you handle injection molding and tooling?
Yes — we support tool design/fabrication, T1 sampling, iterations, and production molding with resin lot traceability.
What tolerances are realistic for plastics?
Baseline guidance: CNC plastics ±0.002–0.005″ depending on geometry and material. Molded dimensions vary with part size, wall thickness, and process window; we’ll confirm after DFM/tooling review.
Can you help with material selection and mold flow?
Absolutely. We provide material guidance and coordinate mold-flow simulation to address warp, sink, and knit-line risks before tooling.
How should I scope my RFQ?
Share CAD + PDF with GD&T, resin grade & color, cosmetic/texture callouts, expected volumes, documentation needs (traceability/PPAP), packaging, and schedule. Start your plastics quote — include resin grade/colour, cosmetic areas/texture, documentation list, and your schedule.
