Custom CNC Machined Parts & Non-Standard Components

The surface the cutter leaves — visible tool marks, Ra 3.2 µm by default.

Use it when: Internal or covered faces; no masking, no lead time.

Uniform matte that erases tool marks and keys paint or adhesive.

Use it when: Before coating, or when a consistent matte look is wanted.

Blast for a matte base, then anodize and dye — deep even colour, no tool marks.

Use it when: Visible aluminium parts where colour and texture both matter.

An oxide layer grown into the metal, dyed and sealed — hard, corrosion resistant, non-conductive.

Use it when: Handled and visible aluminium; colour without paint.

A thicker, denser oxide than Type II — much harder surface, fewer colours, matte grey to black.

Use it when: Wear surfaces and parts handled hard.

Blast then hard anodize: uniform matte grey-black with Type III wear resistance.

Use it when: Functional parts that also have to look consistent.

A chromate conversion layer that protects the surface but stays conductive — the opposite of anodizing.

Use it when: Parts that must be earthed or carry current, and aluminium to be painted.

The class of coating behind alodine/Iridite — thin, conductive, a key for paint.

Use it when: Aerospace and electronics aluminium where conductivity matters.

A conversion coating that darkens the surface with almost no dimensional change, and holds oil.

Use it when: Tools and fasteners where black matters more than corrosion resistance.

Removes free iron so the chromium oxide layer rebuilds. No colour change, no size change.

Use it when: Every machined stainless part that sees moisture, food or medical service.

Electrochemical polish that removes a microscopic layer — bright, smooth, easy to clean.

Use it when: Hygienic and high-vacuum parts.

Acid removal of scale, heat tint and embedded iron after welding or heat treatment.

Use it when: Welded assemblies and parts that were heat treated.

A directional abrasive finish — fine parallel lines and a uniform sheen.

Use it when: Visible panels where a machined look is the intent.

Fine abrasive step that removes machining marks and leaves a low sheen.

Use it when: Preparation for paint or anodizing; a satin look without polishing.

A finishing pass with a sharp tool and a light depth of cut — the practical limit without grinding.

Use it when: Functional faces where Ra 1.6 µm is enough.

Wet paint in a flat sheen, any RAL colour — thinner than powder coat and cheaper in small runs.

Use it when: Colour-critical parts in low volume and prototypes.

The same paint with a gloss sheen — sharper reflections, defects show more than on matt.

Use it when: Consumer-facing parts that are expected to be glossy.

A cured polymer layer, thicker and tougher than paint, in any RAL colour.

Use it when: Outdoor hardware, frames and colour-critical metal parts.

The same powder system with a gloss finish — harder to hide surface defects, easier to wipe clean.

Use it when: Equipment housings and parts that must look new for longer.

A hard decorative layer over a nickel base — high reflectivity and good wear resistance.

Use it when: Appearance-critical parts and hard, low-friction surfaces.

Hard decorative layer with good corrosion resistance; electroless nickel coats internal features evenly.

Use it when: Visible hardware, contacts and wear surfaces.

A sacrificial zinc layer in blue-white, yellow or black — standard protection for steel fasteners.

Use it when: Steel parts exposed to atmosphere, where cost matters.

The lowest-resistance plating, used where conductivity or a bright white finish is the point.

Use it when: Electrical contacts, RF parts and decorative hardware.

A thin gold layer for contact resistance, tarnish resistance and appearance.

Use it when: Connector contacts and premium visible hardware.

A soft, solderable, matte silver layer — used for solderability rather than looks.

Use it when: Parts that will be soldered and busbars.

Vacuum metallising under a matt topcoat — a metallic look without plating the substrate.

Use it when: Plastic housings that need a metal appearance.

The same process with a gloss topcoat — mirror-like, chrome-substitute on plastic.

Use it when: Cosmetic plastic parts, decorative trims.

Electrodeposited paint that covers every surface including edges and internal corners, evenly.

Use it when: Parts with complex geometry where spray would miss surfaces.

A vacuum-deposited hard film in gold, black or blue tones — hard, thin, durable.

Use it when: Wear parts and premium finishes without a plating line.

Permanent marking by removing or altering the surface — no ink, no tooling.

Use it when: Serial numbers, UDI codes and logos that must survive the part.

Ink printed through a screen — flat, fast, and the cheapest way to add text or a legend.

Use it when: Legends, scales and simple graphics on flat faces.

Chemical or laser removal of material to create recessed marks or textures.

Use it when: Branding with a recessed feel, and textured grip areas.

Colour absorbed into an anodised layer or a porous plastic — deep, even, no paint film.

Use it when: Colour on anodised aluminium without a coating thickness.

Anything not on this list — assembly marking, masking, special coatings, customer-specified processes.

Use it when: When the drawing names a finish that is not standard.
