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.

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.
