Surface Finishing Advantages

Advanced Corrosion Protection

Anodising, electroplating and passivation layers defend against corrosion and extend lifespan in challenging environments.

Superior Wear Resistance

Type III hardcoat, chromium plating and hardface coatings dramatically improve wear resistance for high-friction applications.

Exceptional Aesthetics

Custom-colour powder coating, polishing and decorative plating turn functional components into visually appealing finished products.

FDA & Medical Compliance

FDA-compliant processes for food-contact and medical device applications, with full documentation and biocompatibility verification.

Precision Colour Matching

Advanced colour formulation and batch controls ensure perfect colour consistency across production runs and component families.

Batch Consistency & Quality

Rigorous process controls, automated thickness verification and thorough inspection keep every component within spec.

Surface Finishing Process

Part Cleaning & Preparation

Components cleaned of oils, oxides and contaminants. Pre-treatment includes degreasing, acid pickling and surface activation as required.

Pre-Treatment & Surface Activation

Specialised pre-treatment prepares surfaces for optimal adhesion — alkaline cleaning, activation, primer application as appropriate.

Coating Application & Processing

Anodising, plating, powder coating or polishing applied with precise parameter control. Automated systems ensure uniform thickness and consistent quality.

Curing & Thermal Processing

Controlled curing temperatures and times maximise hardness, adhesion and durability for each process.

Comprehensive Quality Inspection

Every component undergoes thickness verification, adhesion testing, visual inspection and functional testing with detailed reports.

Every Finish, and When to Use It

Surface finishing does three jobs: it protects the part from corrosion and wear, it sets the appearance, and sometimes it changes a functional property like hardness or electrical insulation. The right finish depends on the base material and what the part has to survive. Here is how the common finishes compare.

For the full anodizing decision — thickness, hardness, colour and the all-important growth compensation — read our Type II vs Type III guide.
For hard, thin coatings on steel, titanium and carbide, compare PVD coatings and our TiN vs DLC vs CrN guide.
For the complete finish-selection logic across all substrates, see our surface finishing guide.

Finish	What it does	Best on	Notes
Type II anodizing	Corrosion + colour, thin oxide	Aluminium	Full colour range; small dimensional change
Type III hardcoat	Wear + corrosion, thick hard oxide	Aluminium	Grows the part — machine to compensate
Electroplating	Nickel/chrome/zinc/gold layer	Steel, brass, aluminium	Wear, corrosion, conductivity or looks
Powder coating	Thick durable colour layer	Most metals	Tough, wide colour, non-line-of-sight
Polishing	Cosmetic / low Ra	Most metals	Mirror or satin; often before plating
Passivation	Restores corrosion resistance	Stainless steel	Removes free iron; no colour change
PVD coating	Hard, thin, decorative/functional	Steel, Ti, carbide	TiN/DLC/CrN — see our PVD service

Finishing Changes Dimensions — Design for It

A finish that adds or removes material changes the finished size of the part, and on some processes the change is big enough to blow a tight tolerance. Type III hardcoat is the classic example: roughly half the oxide grows outward and half penetrates, so an outside diameter grows by about the full coating thickness and a bore shrinks by the same. The fix is to machine the part to compensate before finishing, or to mask critical surfaces so they are not coated at all.

Because we machine and finish in-house, we work backward from the finished-part tolerance so the machined dimension already accounts for the coating. Tell us the finish on the drawing and we handle the compensation — the detail is in our anodizing guide.

Match the Finish to the Metal

Not every finish works on every metal, and this trips up first-time buyers. Anodizing only works on aluminium and a few other valve metals — you cannot anodize steel or brass. Passivation is specific to stainless. Plating and powder coat are broad. Getting this right at the design stage avoids a re-spec later.

Aluminium → anodizing (Type II/III), chromate, powder coat, plating.
Stainless steel → passivation, electropolishing, PVD, powder coat.
Brass → polishing + lacquer, or nickel/chrome/gold plating (not anodizing).
Titanium → anodizing (colour by voltage), PVD, passivation.

Frequently Asked Questions

What is the difference between Type II and Type III anodising?

Type II (sulfuric-acid) produces a 10-25 µm coating for general corrosion protection and aesthetic enhancement. Type III hardcoat is a thicker, harder 25-75 µm coating for superior wear and corrosion resistance — used in aerospace, hydraulics and high-performance applications.

What colours are available for anodising?

Standard clear, natural, black and metallic shades are available, plus custom colour matching. Not all colours are achievable with anodising — powder coating offers unlimited colour options.

What coating thickness is typical for electroplating?

Nickel plating 5-25 µm; chromium 0.5-5 µm (usually over nickel); zinc 5-50 µm for corrosion protection. Thicker coatings give more protection but require longer plating times.

Can you combine multiple finishing processes?

Yes — combinations such as anodising + polishing, or nickel + chromium plating, are common. We engineer combinations to optimise functional and aesthetic properties.

What is the lead time for surface finishing?

Standard finishes 5-10 business days from receipt of parts. Rush service available with expedited fees. Lead time depends on complexity, batch size and finish type.

Are your finishing processes FDA compliant?

Yes. We maintain FDA compliance for food-contact and medical device components, meeting FDA, ISO and relevant regulatory standards with complete documentation.
