Anodizing (Type II and III), bead blasting, passivation, powder coating, and laser marking — all done in-house on the same workshop floor as the machining. No shipping parts to a coating house, no extra week in transit. Single-source accountability.
Many CNC shops outsource finishing. The part ships to an anodizer, sits in their queue, gets done, ships back. That adds a week to every order, introduces a second vendor's quality system to your part, and makes warranty disputes complicated — whose fault was the streaky anodize?
We run our own anodizing line, blast cabinets, passivation tanks, powder booth, and laser marker. When a part comes off the machining center with a surface-finish requirement, it walks 20 meters to the finishing cell and gets processed that day. The same engineer who specified the finish oversees it. If something looks wrong, we catch it before shipping — not after it lands at your dock.
Specialty coatings we send to qualified partners: electroless nickel plating, hard chrome plating, PVD/DLC coatings, Parylene, and precision polishing (to Ra 0.05 μm or below). We vet every partner and include their work in our quality system. You see a single invoice.
| Machine | Capacity | Spindle / Capability | Qty | Typical use |
|---|---|---|---|---|
| Anodize line (Type II) | 1200 × 600 × 800 mm | Clear, black, red, blue, gold, custom | 1 | 5–25 μm films |
| Hard anodize (Type III) | 1000 × 500 × 700 mm | Natural gray, black | 1 | 25–75 μm films |
| Bead blast cabinets | 600 × 600 × 600 mm | #80–#220 glass or ceramic | 3 | Matte uniform texture |
| Passivation line | 500 × 300 × 500 mm bath | Nitric or citric acid, ASTM A967 | 1 | Stainless corrosion resistance |
| Powder coat booth | 1500 × 800 × 1200 mm | RAL/Pantone colors, textured | 1 | 50–125 μm film |
| Laser marker (fiber) | 100 × 100 mm field | Alphanumeric, 2D codes, logos | 2 | Permanent, no dye |
Consumer electronics enclosures, camera gear, aerospace ground hardware. 5–25 μm film, dyes well in most standard colors.
Pistons, wear plates, firearms components, industrial valves. 25–75 μm film, 400–500 HV surface hardness.
Removes machining marks, creates uniform matte finish. Ideal substrate for subsequent anodizing or powder coat.
Removes free iron from stainless surfaces, restores chromium oxide layer. ASTM A967, nitric or citric acid per customer preference.
Steel parts where a durable black finish is needed but anodize/paint isn't appropriate. Mild corrosion resistance, no dimensional change.
Serial numbers, lot codes, 2D data matrix codes, logos. Contrast on anodized aluminum is excellent; on bare metals, it's a dark etch.
