★★★★☆
Reliable anodizing
Type III hard anodize on aluminum housings came out even and to the right thickness. Good communication throughout.

Overview
Mechpart delivers a complete suite of surface treatment and finishing services engineered to enhance corrosion resistance, wear performance, aesthetic quality, and electrical conductivity of your manufactured parts. Our in-house and partnered finishing lines cover anodizing (Type II sulfuric, Type III hardcoat in colors including clear, black, red, and blue), electroplating (zinc with trivalent Cr3+ passivation, nickel, hard chrome, electroless nickel), powder coating (epoxy, polyester, hybrid formulations with RAL color matching), and conversion coatings (Alodine, phosphate). Every finish is processed to RoHS and REACH compliance with full certification provided.
Our surface-treatment expertise extends across aerospace (MIL-spec anodizing and passivation), automotive (corrosion-resistant underbody brackets and aesthetic trim pieces), medical-device housings (biocompatible electropolishing), consumer electronics (conductive chromate coatings on aluminum heatsinks), and architectural fittings (weather-resistant powder-coated railings and cladding). We handle parts ranging from M2 fasteners to 3-meter structural extrusions, with rack and barrel processing available to optimize cost for your batch size.
Why outsource surface treatment to Mechpart? Because we eliminate the logistics headache of splitting manufacturing across three vendors. Send us your machined, cast, stamped, or forged parts—they return to you fully finished, inspected, and sealed for shipment under one purchase order and one quality system. Standard lead time is 1–2 weeks with expedited 72-hour turnaround available. MOQs start at one lot; volume pricing scales transparently. Finish strong with a partner who treats the last micron of coating as carefully as the first.

Frequently asked
Which finish gives the best corrosion resistance?
Dacromet and hot-dip for steel; hard-anodize for aluminium; passivation for stainless.
Can you match a specific color?
Yes — anodize and powder coat to any RAL/Pantone with batch consistency.
Do you verify coating quality?
We measure thickness, adhesion and hardness and salt-spray test to your spec.
Can you finish parts we machined elsewhere?
Yes — we accept customer-supplied parts for finishing only.
