END-TO-END SURFACE SOLUTIONS

Formex offers a diverse range of surface treatment solutions for our clients, covering everything from sample design to mass production.

01.

Surface Modification

Sandblasting

We offer 30 – 220 grit bead blasting, aqua blasting and all colours of anodising including colour matching.

Knurling

Creates a non-slip textured surface for grip, locking, and identification. Used for knobs, fasteners, mechanical parts, and tools—pressure knurling for ductile metals; cut knurling for hard metals/precision parts.

Chromium plating/nickel plating/zinc plating

Used for metal parts requiring corrosion resistance, wear resistance, or decorative finishes.

QPQ

Enhances part surface strength and service life, suitable for precision gears, machine tool spindles, etc.

Laser Engraving

Used for logo or pattern customization. Forms precise patterns, text, or hollow structures via laser.

Nitriding

Nitriding/QPQ

Enhances part surface strength and service life, suitable for precision gears, machine tool spindles, etc.

Mirror Polishing

Used for metal parts and products requiring a smooth, reflective surface, such as automotive trim, medical instruments, kitchenware, and precision mechanical components.

Electropolishing

an electrochemical surface finishing process that removes micro burrs and levels metal surfaces to achieve ultra-smooth, bright, corrosion-resistant mirror finish.

Laser Engraved carbon fiber texture

laser engraving texture is suitable for product design.

Passivation

Passivation(SUS)

No artificially formed conversion film. Treatment removes free iron and oxide scale; a native thin oxide film forms naturally on the metal in air.

Brushing

Brushed finish creates fine, uniform lines on metal surfaces for an elegant, matte metallic look and improved scratch resistance.

Carbonitriding

is a thermochemical heat treatment that diffuses both carbon and nitrogen into steel’s surface to achieve hard, wear-resistant layers with better corrosion resistance than carburizing alone.

Stress relief tempering

is a low-temperature heating process to eliminate internal residual stress inside metal workpieces while avoiding obvious hardness drop.

Chemical etching

a precision machining process that uses corrosive chemicals to selectively remove metal material for creating intricate, burr-free patterns and thin custom components.

Flame polishing（PC）

is a surface finishing technique that melts the edge of polycarbonate briefly with flame to remove scratches and achieve crystal-clear glossy smoothness.

Organic Coating

Painting/UV Coating

Plastic painting + UV coating

Painting

We support color customization based on Pantone/RAL color charts, with glossy, semi-matte, and matte finishes available.

Powder Coating

a dry electrostatic coating process that applies pigmented powder onto metal surfaces and cures it under heat to form a tough, uniform, scratch-resistant protective decorative film.

Painting

Matte black

Phosphating

is a chemical pretreatment process that forms a thin adhesive phosphate film on metal surfaces to boost paint adhesion and provide temporary rust protection.

Electrophoretic coating

(E-coating) is an immersion electroplating painting process that deposits an even, pinhole-free protective paint film on all metal surfaces including hidden gaps for superior anti-corrosion performance.

Micro-arc oxidation (MAO)

is an electrochemical surface treatment for aluminum, magnesium and titanium alloys to grow dense, hard, wear-resistant ceramic oxide layers with superior corrosion resistance.

Sand Texture PU Liquid Spray

Matte Fine Sand Texture PU Liquid Spray Coating (Soft-touch Grain / Particle Grain Topcoat)

Speckle Spraying

is a coating process that sprays scattered granular spots on surfaces to create mottled textured finishes.

Spray painting with water-based coating

Water-based paint is an eco-friendly, low‑odor coating with excellent adhesion and weather resistance.

Logo Epoxy Doming

A process that applies a clear, raised epoxy resin layer to logos, enhancing gloss, durability, and UV/salt spray resistance for long-lasting protection and visual impact.

Logo Paint Filling

Sandblasting uses high-pressure abrasive to create a uniform matte, textured surface that hides scratches and improves coating adhesion.

Conversion Coating

Anodizing

Anodized+ Sandblasted

Anodizing is an electrochemical surface treatment process primarily used for aluminum. Enables color customization and offers protective effects for aluminum parts.

Blackening

is a surface treatment that forms a black oxide layer on steel parts. It provides corrosion resistance, a clean black finish, and good dimensional stability.

Blue anodized+sandblasted 120mesh

Brass anti-tarnish passivation

a chemical treatment that forms an invisible protective film on brass surfaces to prevent oxidation, discoloration and tarnishing while preserving the original metallic luster.

Gradient anodization

achieve gradient anodization effects, or create diverse surface finishes through exposure development and laser engraving.

Copper black oxide

is a conversion coating that generates uniform black anti-tarnish film on copper alloys via alkaline chemical reaction.

Splatter &Splash-ink anodization

is a decorative conversion coating for aluminum, creating random multi-color splashed ink patterns by splashing multi-tonal dyes into porous sulfuric anodic film before sealing.

Anodized +Sandblasted

We offer 30 – 220 grit bead blasting, aqua blasting and all colours of anodising including colour matching.

Chromate-free passivation

is an environmentally safe metal surface treatment that forms a protective anti-corrosion film without any chromium compounds.

Gold Plating

A surface processing technology that enhances conductivity, improves corrosion resistance, and imparts a metallic luster.

Silver-plating

Deposit a thin silver layer on a substrate to improve appearance, electrical conductivity, corrosion resistance, and solderability.
