What are the advantages of using sandblasting equipment for surface treatment of communication equipment parts?

Core benefits of sandblasting surface treatment for communication equipment parts

Communication equipment parts are mostly aluminum alloy, die-casting aluminum, stainless steel, sheet metal and precision structural parts. The advantages of surface treatment by sandblasting are very suitable for the needs of the industry, mainly including these:

1. The surface is decontaminated and oxidized to improve the cleanliness.

Remove scale, burr, oil stain, rust and carbon deposit in die casting;

The cleaning machine processes the knife pattern and mold demoulding residue, so that the surface of the parts is uniform and clean, which meets the requirements of communication precision assembly.

2. Build a uniform matte matte texture with good appearance consistency.

Form a fine and even matte matte surface without glare, which meets the appearance standards of base stations, cabinets and antenna housings;

Batch processing has small color difference and uniform texture, which is suitable for appearance control of mass production of communication equipment.

3. Greatly enhance the adhesion of subsequent painting/anodizing.

Micro-rough concave-convex surface is formed on the surface after sandblasting to increase the contact area;

Subsequent powder spraying, painting, anodizing and electrophoresis have stronger adhesion, and are not easy to peel, fall off and blister, and the weather resistance of outdoor communication equipment is greatly improved.

4. Eliminate surface stress and strengthen fatigue resistance.

Sand blasting and light shot peening to strengthen and seal micro-capillary cracks;

Release the internal stress caused by machining, bending and welding, improve the anti-vibration, anti-fatigue and anti-cracking ability of communication structural parts, and adapt to the long-term outdoor working conditions of base stations.

5. Small size deformation, suitable for precision communication parts.

The controllable sand blasting process has small cutting amount and extremely low deformation;

Suitable for cavities, filters, communication precision sheet metal and thin-walled parts, without affecting the assembly tolerance.

6. Chamfering and deburring, replacing labor and saving cost.

Inner and outer holes, corners, and cracks are gently chamfered and deburred at one time;

Instead of manual grinding, it has high efficiency and good consistency, and reduces labor cost.

7. Improve corrosion resistance and insulation adaptability.

Uniform surface structure, reducing electrochemical corrosion points;

It is beneficial to the bonding of insulation coating and sealant of communication parts, and improves the waterproof, dustproof and anticorrosive properties of the whole machine.

8. Adapting to multiple materials and having strong versatility.

It can process common communication materials such as die-casting aluminum, 6061/6063 aluminum, stainless steel, galvanized sheet, magnesium alloy, etc., and has strong process compatibility, which is suitable for mass production of all kinds of communication parts.
