Polishing

Surface smoothing to improve appearance or prep for anodizing.

Types: Mirror polishing / satin finish / vibration polishing

Applications: Smart hardware, bicycle parts, consumer electronics

Anodizing

An electrochemical process that creates a corrosion-resistant and decorative oxide layer. Available in clear, black, red, blue, and more.

Features: Hardness, corrosion resistance, customizable colors

Options: Type II (decorative), Type III (hard anodizing)

Electroplating

Deposits a thin metallic layer (e.g., nickel, chrome) onto the part for improved conductivity, wear resistance, or visual finish.

Features: Electrical conductivity, shine, smoothness

Common Types: Nickel, chrome, zinc

Electrophoresis

Ideal for uniform, corrosion-resistant coatings in complex geometries. Often used as a primer or topcoat for color and protection.

Best for: High-volume or intricate parts

Features: Uniform thickness, good adhesion, excellent corrosion resistance

Custom Coatings

We also support powder coating, painting, or customized multi-layer finishes for unique projects or industrial needs.

WHAT IS “FORGING”?

forge [fôrj]                                          锻造【鍛造】

VERB
make or shape (a metal object) by heating it in a fire or furnace and beating or hammering it.

Data from Oxford Languages

Hot die forging‌ is a precision forging process where solid metal billets are heated above their recrystallization temperature and formed under high pressure within precisely engineered dies. This method achieves near-net-shape components through controlled plastic flow,often eliminating the need for extensive machining. Simultaneously refining grain structure via dynamic recrystallization to enhance mechanical strength and fatigue resistance. Unlike casting, it produces high-density parts through solid-state deformation without molten metal filling, making it essential for critical load-bearing applications like automotive transmission gears and aerospace engine components.

Inside the Hot Forging Process

Heated metal is pressed under high pressure into a precision steel die, where it flows to fill the cavity and takes the shape of the tool. In the process, the metal’s grain structure is refined, resulting in parts with superior strength and durability. This process is ideal for producing high-performance components with excellent mechanical properties.

FAQ’s

Do you have questions for our services

We’ve answered some of the most common questions about our surface treatment services.
Have something else in mind? Just reach out — we’re here to help.

Yes, all finishes meet RoHS and REACH standards. Certificates and salt spray or film thickness test reports can be provided upon request.

02. How do you ensure color consistency in anodizing?

We control raw material batches, forging direction, and surface prep to reduce variation. Each order follows a standard process with color samples confirmed before mass production.

Standard Type II anodizing is 8–15μm. For hard anodizing (Type III), we offer 25–50μm based on your functional or drawing requirements.
