About the Process

Built for Performance

Our aluminium anodising process transforms the component surface into a durable oxide layer engineered for demanding operating conditions.

Type III hard-coat anodising provides increased surface hardness, abrasion resistance and corrosion protection while retaining the lightweight properties of aluminium.

The process is suitable for precision components where coating consistency, dimensional control and repeatable finishing quality are critical.

Manufacturing Process

Controlled at Every Stage

From preparation to final inspection, every stage is controlled to achieve consistent and repeatable surface performance.

01
Preparation

Degreasing & Etching

Controlled cleaning and etching prepare a uniform aluminium surface.

02
Treatment

Hard-Coat Anodising

Controlled electrolyte conditions create a dense protective oxide layer.

03
Protection

Sealing

Controlled sealing improves corrosion resistance and closes the pore structure.

04
Verification

Inspection & QA

Coating thickness and specified quality checks are completed before dispatch.
