Overview
Pearson Manufacturing supports a wide range of functional and cosmetic finishing processes — including coatings, plating, polishing, and marking. We coordinate scheduling, traceability, and inspection, routing your job in-house or through certified Canadian partners based on geometry, timing, and scale.
⚠️ Hybrid fulfillment: some finishes occur in-house; many are completed through certified partners under Pearson QA.
Quick Specs
| Process | Best For | Throughput | Notes |
|---|---|---|---|
| Powder Coating | Durable color, cosmetics, corrosion resistance | High | Specify RAL/Pantone, gloss, texture; allow 2–4 mil build; mask threads/fits |
| Anodize Type II | Aluminum corrosion/wear + color options | Medium | Dye/clear; 0.0002–0.001″; minor dimensional growth — call out critical fits |
| Anodize Type III | Hard wear resistance on aluminum | Medium | Hardcoat; 0.0005–0.003″; darker tones common; keep tight bores as-machined |
| Chem Film (Alodine) | Electrical continuity, paint base on aluminum | High | MIL-DTL-5541 Type I/II; minimal build; note masking for grounding areas |
| Passivation (SS) | Free-iron removal on stainless | High | ASTM A967 / AMS2700; citric or nitric; no measurable build |
| Electroless Nickel | Uniform corrosion & wear protection | Medium | MIL-C-26074 / AMS2404; low/mid/high-phos; 0.0005–0.001″ typical |
| Zinc Plating | Economical protection for steel hardware | High | ASTM B633 Type + SC1–SC4 define finish and thickness; chromate options |
| Bead Blast / Polish | Texture control & cosmetic prep | High | Specify media/roughness (e.g., Ra) for consistency on visible faces |

- Powder Coating: Film 2–4 mil typical; adhesion per ASTM D3359; gloss per ASTM D523 (as specified)
Design for Manufacturability (DFM)
- Provide a finishing drawing with RAL/Pantone, gloss (e.g., ASTM D523), texture, and which faces are cosmetic.
- Call out masked features (threads, datums, sealing faces, bores). Add a simple mask map if features are numerous.
- Account for coating build on close fits — especially powder coat and hard anodize. Keep critical bores as-machined or final-machine after finish.
- Specify marking content, location, and barcode size; confirm contrast requirements for laser on anodized or coated surfaces.
- Break sharp edges on cosmetic faces to reduce chipping; specify uniform blast media and target roughness (Ra).
- List substrate/alloy (e.g., 6061-T6, 7075-T6, 1018, 4140, 304/316) and any environmental or regulatory needs (RoHS/REACH).
We’ll review your finishing drawing and confirm achievable specs with the fastest viable routing (in-house or partner) before kickoff.
Typical Applications
- Machined aluminum parts with clear/black anodize (Type II) or hardcoat (Type III)
- Powder-coated sheet metal enclosures, panels, and brackets
- Steel pins/shafts with electroless nickel for wear and corrosion resistance
- Laser-engraved branding, serial numbers, and QR/Barcodes for traceability
- Passivated stainless components for food, medical, or outdoor service
- Chem film on aluminum for paint adhesion and electrical continuity
Coating & Finishing FAQs
How fast can you quote finishing?
Same business day for most RFQs. Upload your drawing with color/spec, masking notes, quantities — we will confirm price, lead time, and routing (in-house or partner).
Can you match a specific color or gloss?
Yes. Provide a physical sample or a RAL/Pantone reference. We can produce sample panels for approval when needed.
Do you handle masking and threads?
Absolutely. We mask threads, datums, sealing faces, and bores per drawing. Include a simple mask map for many features.
What finishes impact dimensions the most?
Powder coat (2–4 mil typical) and Type III hard anodize (0.0005–0.003″) add measurable build. Keep tight fits as-machined or finish-machine after coating. Passivation and chem film have negligible build.
What documentation can you provide?
Certificates of Conformance, color lot data, RoHS/REACH, and dimensional/finish reports where applicable.
Do you offer rush options?
Often yes. Note your required date on the RFQ and we will propose the fastest viable routing and shipping method.
