Precision CNC Machining & Rigorous Process Control for High-Frequency Hardware

In RF and SATCOM hardware manufacturing, sub-micron tolerances and surface finish directly impact signal integrity and insertion loss. Backed by AS9100 and ISO 9001 certifications, CTT leverages in-house 5-axis CNC machining to deliver extreme dimensional accuracy, intricate sealing groove milling, and tight surface roughness (Ra) control. From prototype development to volume production, we ensure superior mechanical and RF performance for aerospace, LEO satellites, and ground stations.

1.Surface Cleaning and Pre-treatment:

• Remove surface dirt, grease, and residues to ensure the effectiveness of subsequent treatments.
• Use methods such as solvent cleaning, acid washing, and alkaline washing for surface pre-treatment.

2.Surface Polishing and Buffing:

• Reduce surface roughness to the desired level through mechanical or chemical methods.
• Improve appearance quality, reduce surface defects, and enhance corrosion resistance.

3.Oxidation Treatment:

• Treat metal surfaces to form an oxide layer, improving corrosion and wear resistance.
• Methods include anodizing and other oxidation treatments.

4.Metallization Treatment:

• Cover the metal surface with a layer of metal to enhance corrosion resistance and mechanical properties.
• Includes processes like galvanizing, nickel plating, and chrome plating.

5.Painting and Coating:

• Use coatings to protect the surface, enhancing corrosion resistance, wear resistance, and appearance quality.
• Includes methods such as painting, powder coating, and electrophoretic coating.

6.Hardening Treatment:

• Increase the hardness and strength of materials through heat treatment or other methods.
• Includes heat treatment processes like quenching and tempering.

7.Surface Modification:

• Change surface properties through chemical or physical methods to improve mechanical, chemical, or optical performance.
• Methods include surface deposition, sputtering, and others.

8.Pore Sealing and Sealing:

• Seal micro-pores and cracks on the surface to prevent corrosion and liquid penetration.
• Includes methods like fluorocarbon sealing.

9.Hermetic Sealing & Advanced Surface Finishing

The application of these surface treatment techniques depends on the material of the product, design requirements, and desired final performance. Choosing the appropriate surface treatment method can enhance the durability, reliability, and appearance quality of the product.
