Surface Cleaning and Pre-treatment
Laying a Solid Foundation for Quality
Sand Blasting / bead blasting
Sand blasting is the critical pre-treatment step that refines part surfaces for optimal downstream processing. High-velocity abrasive media removes oxide scale, rust, and machining burrs, while intentionally creating a uniform micro-roughness. This textured surface dramatically improves the mechanical interlocking of subsequent coatings or plating layers, preventing delamination and ensuring long-term adhesion.
Ultrasonic Cleaning
Ultrasonic cleaning delivers unparalleled surface purity, targeting contaminants that conventional cleaning methods cannot reach. High-frequency sound waves generate microscopic cavitation bubbles that penetrate blind holes, narrow gaps, and complex geometric features. This process thoroughly eliminates residual abrasive particles, oil residues, and dust, creating a chemically clean surface that is essential for consistent, high-quality electroplating results.
Electroplating
Electroplating is the finishing process that transforms pre-treated parts into high-performance components. Building on the clean, roughened surface from sand blasting and ultrasonic cleaning, a uniform metal layer is electrochemically deposited. This layer enhances corrosion resistance, wear resistance, and electrical conductivity, while also providing an aesthetically consistent finish. The rigorous pre-treatment ensures the plating adheres firmly, delivering reliable performance even in demanding industrial environments.

Tailored Surface Finishes

Name
Explanation
As machined (Ra 3.2μm / Ra 126μin)
This finishing option with the shortest turnaround time. Parts have visible tool marks and potentially sharp edges and burrs, which can be removed upon request.
Smooth machining (Ra 1.6μm / Ra 63μin)
Smooth machining is similar to a ‘As machined’ finish, but with less visible machine marks. Parts are machined at a lower feed rate, with no hand polishing.
Polishing (Ra 0.8μm / Ra 32μm)
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment.
Bead Blasting
Machined parts are bead blasted with glass beads which results in a uniform grainy texture and reduced machining marks.
Vibratory finishing
A process that removes burrs, sharp edges, and machining marks from workpieces by tumbling them with vibrating media.
Bead blasted + Anodizing
Before anodizing, the parts are sandblasted with 120-grit sandpaper—an ideal method to improve the corrosion resistance and appearance of aluminum parts.
Black Oxide
Black oxide is a conversion coating that is used on steels to improve corrosion resistance and minimize light reflection.
Plating
Include Nickel Plating, Silver Plating, Gold Plating, Zinc Plating, Chrome Plating, Tin Plating and etc, it is ideal to reduce corrosion, improve the appearance and function of solderability and electrical conductivity.
DLC (Diamond-Like Carbon) Coating
DLC (Diamond-Like Carbon) coating is a hard, wear-resistant coating made of a carbon-rich material that exhibits some of the properties of diamonds.
Three Core Reasons to Choose Us
Your Surface Treatment Expert, Covering All Needs
01
We cover all surface treatment processes—from pre-treatment (sand blasting, pickling) to high-end modification (laser treatment, carburizing/nitriding). Tailored solutions for materials (steel, aluminum, etc.) and scenarios (corrosion resistance, wear resistance) meet diverse needs, no “one-size-fits-all.”
02
With refined control over key parameters (plating density, coating thickness), we ensure core indicators (adhesion, salt spray resistance, hardness) exceed industry standards. Proven results across bridge structures, engine blades, and electronics guarantee durable protection and stable performance.
03
The excellent structural properties of engineering-grade CNC machined plastics, including electrical insulation and strength-to-weight ratio, make them ideal for plastic machining. Thus, with plastic machining, machinists can use a wider range of materials for plastic fabrication, with popular ones including HDPE, ABS, Nylon, Acrylic, Delrin, PEEK, and so on.
