Surface treatment

We provide diversified, high-quality, and efficient metal surface treatment services.

Surface treatment

Comprehensive and diversified surface treatment has long been TIANTEC’s core strength. From pre-treatment processes such as sandblasting, polishing, and deburring to advanced coating technologies including painting, electrophoretic coating, powder coating, PVD titanium plating, and anodizing, we deliver uniform, durable, and visually appealing finishes for metal components.
Whether enhancing functional performance or adding high-value decorative appeal, we provide complete surface treatment solutions that help clients elevate product quality and strengthen market competitiveness.

Our Key Capabilities

Our long-term experience enables us to provide our clients with better solutions, more cost-effective options, and superior service.

Abrasive Blasting & Peening

In metal surface pre-treatment, we often utilize abrasive blasting and peening techniques, including sandblasting and shot peening. Our extensive experience ensures consistent and uniform surface finishes. By precisely controlling process parameters, we achieve optimal surface quality while minimizing substrate damage from excessive blasting.

Thorough Surface Cleaning

Consistent Roughness Enhancement

Surface Mechanical Strengthening

Deburring and Edge Rounding

Improved Surface Consistency and Aesthetics

Polishing, Grinding and Deburring

It is difficult to achieve the final effect directly after forming, so we need to initially refine the surface through physical treatments such as polishing, grinding, and deburring. These are our most routine tasks, and through extensive business experience, we have developed an efficient, high-quality, and systematic processing approach. We have distinct advantages in handling complex geometries, controlling material removal and tolerances, and ensuring consistent production quality.

Surface Quality Improvement

Eliminate Burr Interference in Assembly

Reduce Stress Concentration

Provide Uniform Substrate

Strict Process Control for Consistency

Painting

After high-standard pre-treatment, the surface consistency and coating adhesion of our products are greatly enhanced, strengthening our advantages during the painting stage. Throughout the painting process, we maintain strict standards, carefully controlling coating uniformity and color consistency. Using enclosed automated spray booths minimizes the impact of dust, contaminants, and static interference.

Strict Control of Coating Uniformity

Precise Color Consistency Control

Premium Aesthetic Finish

Enhanced Surface Protection

Rigorous Defect Control

Powder Coating

Powder coating is a more environmentally friendly, efficient, and stable coating method. Our powder coating lines are capable of high-volume production for most medium-sized products. Once cured, the coating does not require additional drying, providing a clear advantage in production efficiency.

More Environmentally Friendly Production Processes

Stricter Pre-Treatment Standards

Higher Production Efficiency

Enhanced Surface Performance with Thicker Coatings

Significant Cost Advantages from Mass Production

Electroplating

We place a strong emphasis on environmental compliance and are among the few companies in the Ningbo region with authorized electroplating production licenses. Electroplating has long been one of our core strengths. Starting with high-end sanitary product contract manufacturing, we have continuously explored and advanced our electroplating technologies. We have established strict control systems for key production parameters that affect coating uniformity and thickness, as well as for maintaining stable plating solutions.

Enhanced Corrosion Resistance

Increased Wear Resistance and Hardness

Premium Aesthetic Finish

Stricter Environmental Standards

Rigorous Defect Control

PVD Titanium Coating

We also offer PVD titanium coating services. After coating, products achieve significantly enhanced hardness and wear resistance, while presenting a uniform, high-end metallic finish. This technique is commonly used in high-end sanitary products and is equally suitable for applications requiring superior corrosion resistance.

Superior Wear Resistance and Hardness

Excellent Corrosion Resistance

Stable and Controllable Coating

Premium Metallic Luster

Environmentally Friendly Physical Deposition Process

Anodizing

We use aluminum extrusion solutions for a large number of our products, providing greater efficiency, cost-effectiveness, and process stability. Anodizing is the ideal surface treatment for aluminum extrusions. This process imparts vibrant color finishes to aluminum products, produces a stable oxide layer that is resistant to peeling, and is highly suitable for subsequent surface processing of extruded aluminum components.

Our Workshops

Polishing Workshop

For surface finishing and polishing, to remove imperfections, enhance smoothness and flatness, and provide a solid foundation for subsequent processes such as painting, electroplating, and anodizing.

Enclosed Automated Spray Room

Fully enclosed, automated spray room. Ensures uniform coating application and efficient drying, maintaining consistent paint quality while providing a safe working environment.

Powder Coating Production Line

An integrated production line combining spraying, baking, and curing. Achieves uniform coverage of thick coatings, ideal for high-volume metal surface treatment.

Powder Coating Station

Dedicated station equipped with electrostatic powder spraying, suitable for small to medium batch production or localized coating, with powder recovery capability.

Sandblasting Machine

For metal surface cleaning, deburring and roughening. High-speed abrasive particles remove oxides, rust, or old coatings, creating an ideal surface for subsequent coating adhesion.

High-Pressure Sandblasting Machine

By higher pressure, it achieves deep cleaning, deburring, and enhanced surface roughness. Ideal for thick-walled or hard-to-process surfaces, it improves coating adhesion and component durability.
