Surface finishing plays a critical role in improving the
performance, durability, and appearance
of metal parts.
🛡️
Corrosion Resistance
Protects parts from rust, oxidation, and harsh environments, especially for outdoor or high-humidity applications.
💪
Enhanced Electrical Conductivity
Finishes such as nickel or tin plating enhance contact performance in electronic components.
✨
Improved Wear & Scratch Resistance
Hard coatings, such as anodising or electroplating, reduce abrasion and extend the lifespan of the part.
🎖️
Better Aesthetics & Branding
Surface treatments add colour, gloss, or texture, creating a professional look and supporting product differentiation.
✌️
Improved Assembly & Functionality
A surface finish can reduce friction, provide insulation, or enhance the fit during assembly.
🌈
Cost Efficiency
Preventing premature failure through proper finishing reduces maintenance and replacement costs.
Applications of surface treatment
technologies
We master comprehensive surface treatment technologies and can provide the best solutions for your specific material and application requirements.
Chrome Plating
A bright, hard electroplated finish that offers excellent wear resistance, surface hardness, and corrosion protection. Commonly used on mechanical parts, tools, and decorative hardware.
Gold Plating
The electroplated gold layer offers outstanding conductivity, oxidation resistance, and solderability. Ideal for contact springs, connectors, and high-reliability electronic components.
Heat Treatment
A controlled thermal process to enhance the hardness, elasticity, and fatigue life of steel parts, especially springs, stamping dies, and mechanical pins. Can include tempering, annealing, or quenching.
Plasma Surface Activation
A dry, low-temperature treatment that modifies the surface energy of metals to improve adhesion with coatings, inks, or adhesives. Widely used in the medical, automotive, and electronics industries.
PVD Coating (Physical Vapour Deposition)
A vacuum-based process that deposits ultra-thin, wear-resistant, and corrosion-resistant films. Offers strong adhesion and a premium finish. Ideal for surgical tools, high-end electronics, and aerospace components.
Tin Plating
A soft, conductive electroplated coating that offers excellent solderability and low contact resistance. Frequently applied to battery contacts, terminals, and grounding parts.
Nickel Plating
Durable electroplated layer with excellent wear resistance, corrosion protection, and electrical conductivity. Suitable for connectors, spring contacts, and EMI shielding components.
Passivation
A chemical treatment that removes surface impurities from stainless steel, enhancing corrosion resistance without changing dimensions. Commonly used in medical and food-grade components.
Anodising
An electrochemical process used primarily for aluminium, creating a corrosion-resistant oxide layer. Available in natural or dyed finishes. Common in enclosures, brackets, and decorative parts.
Powder Coating
A dry finishing process that applies a thick, uniform, and colourful protective layer. Offers good weather resistance and surface coverage. Widely used in consumer products, lighting, and appliances.
Black Oxide
A conversion coating for ferrous metals that provides minimal corrosion resistance and a matte black appearance. Ideal for springs, fasteners, and control components where thickness is critical.
Polishing / Brushing
Mechanical or chemical finishing methods to enhance surface smoothness or texture. Often used for aesthetic improvement, gloss, or branding purposes in exposed metal parts.
Combination and customised solutions
A single technology often fails to meet all demands. We excel at integrating multiple processes (such as plasma cleaning and electroplating) in a coordinated manner to address complex engineering challenges that a single process supplier cannot handle, and develop truly innovative, customised solutions for you.
Solutions Tailored for Leading Industries
We have a deep understanding of the unique needs of various industries and provide highly professional surface treatment solutions.
Medical Apparatus
In the medical industry, materials must meet the highest standards of adhesion, biocompatibility, sterility, and long-term durability. To address these critical demands, we apply a combination of plasma surface activation, medical-grade coatings, and precision passivation techniques. These treatments ensure secure bonding between components, minimise contamination risk, and extend product life, making them ideal for surgical tools, diagnostic systems, and implant-adjacent assemblies.
Industrial precision instrument
Industrial precision instruments demand the highest standards of surface adhesion, mechanical durability, and corrosion resistance. To meet these stringent requirements, we utilise advanced treatments, including plasma activation, precision coating, and passivation. These processes ensure optimal performance, extend component life, enhance durability, and reduce the risk of surface degradation, making them ideal for use in high-precision equipment, measurement tools, and automated machinery.
Automobiles and aerospace
Metal components used in automotive and aerospace systems must withstand extreme conditions, including high temperature, vibration, and corrosion. We apply advanced surface treatments, including hard anodising, electroplating, passivation, and dry film coatings, to enhance fatigue resistance, wear protection, and thermal stability. These processes ensure structural integrity, long-term reliability, and compliance with industry performance standards.
Electronics and 3C devices
Metal parts used in consumer electronics and 3C devices require precision surface finishing for conductivity, appearance, and corrosion resistance. We offer solutions such as nickel/tin plating, anodising, and polishing to enhance electrical contact, achieve high cosmetic standards, and ensure product stability. These treatments are widely applied in battery contacts, shielding covers, structural frames, and connectors.
We support custom surface finishes based on your functional and aesthetic requirements. Whether you need matte black for consumer electronics, bright nickel for contacts, or colour anodising for aluminium parts, we provide full support from prototyping to mass production.
