Metal Surface Treatment Services for Custom Metal Parts

Complete metal surface treatment solutions to enhance performance & protection.
At SzCrealink, we provide professional metal surface treatment services to improve the performance, durability, and appearance of custom metal parts. With over 19 years of manufacturing experience, we support customers not only with precision machining, but also with reliable, one-stop metal finishing solutions.
From anodizing and plating to coating and chemical treatments, our surface treatment services are designed to help your metal parts perform better, last longer, and meet demanding application requirements.

Why Metal Surface Treatment Matters

Metal surface treatment is a critical step after machining or fabrication. Proper surface finishing can:
Improve corrosion and wear resistance
Enhance surface hardness and durability
Improve electrical conductivity or insulation
Enhance appearance and surface consistency
Extend service life in harsh environments
At SzCrealink, surface treatment services can be provided as part of a complete manufacturing project or as stand-alone metal finishing services, depending on your needs.

1-Electroplating

Electroplating

Applies a thin metal layer using electric current - ideal for enhancing corrosion resistance, conductivity, and surface hardness.

2-Chemical-Treatment

Chemical Treatment

Modifies the metal’s surface through controlled chemical reactions - improves adhesion, corrosion resistance, and surface finish.

3-Hot-Dip-Plating

Hot-Dip Plating

Involves dipping parts into molten metal (like zinc) to create a durable, protective coating - perfect for harsh environments.

4-Reliable-Surface-Finishing-Support

Reliable Surface Finishing Support

From start to finish, SzCrealink ensures your parts not only look great but also perform better and last longer - all backed by a trusted supply chain and years of experience.

Our Metal Surface Treatment Capabilities

We offer a wide range of metal surface treatment services for industrial and custom applications. Each process is selected based on material type, functional requirements, and operating environment.

1.Anodizing Services

Anodizing is an electrochemical process mainly used for aluminum and titanium parts. It forms a durable oxide layer that improves corrosion resistance, wear resistance, and appearance.
Benefits:
Improved corrosion and abrasion resistance
Enhanced surface hardness
Decorative color options
Common applications: Aerospace components, automotive parts, electronics housings, industrial equipment

2.Electroplating & Electroless Plating

Plating services apply a thin metal layer to improve surface properties such as corrosion resistance, conductivity, and wear resistance.
Available plating options include:
Zinc plating
Nickel plating
Chrome plating
Electroless nickel plating
Applications: Fasteners, electronic components, connectors, precision mechanical parts

3.Chemical Surface Treatment

Chemical surface treatments modify the metal surface through controlled chemical reactions. These processes are often used to improve corrosion resistance, surface adhesion, or appearance.
Common chemical treatments:
Black oxide coating
Stainless steel passivation
Phosphating
These treatments are widely used as preparation steps before painting or coating

4.Hot-Dip Plating

Hot-dip plating involves immersing metal parts into molten metal, such as zinc or aluminum, to create a thick, durable protective coating.
Benefits:
Excellent corrosion protection
Long service life in harsh environments
Typical applications: Structural steel parts, outdoor components, industrial equipment

5.Powder Coating & Painting

Powder coating and industrial painting improve both appearance and corrosion resistance. These methods are suitable for parts exposed to weather, chemicals, or mechanical wear.
Advantages:
Uniform surface finish
Strong corrosion protection
Suitable for automated, high-volume production
Applications: Automotive parts, home appliances, construction components, industrial machinery

6.Thermal Spraying

Thermal spraying applies molten metal or ceramic materials to a surface to improve wear resistance, heat resistance, or corrosion protection.
Common thermal spraying processes:
Flame spraying
Plasma spraying
High-velocity oxy-fuel (HVOF) spraying
Applications: High-temperature components, wear-resistant surfaces, large industrial parts
