Quang Khanh Technical Services Co., Ltd. was established on April 8, 2011 with the main function of providing paint spraying services to restore and protect metal for machine parts surfaces as well as structural surfaces. metal. type using HVOF and Plasma metal spraying technology.

The company's service industries include::
1. Metal coating
2. Overhaul of rotating equipment
3. Repair and restore valves
4. Restore Babbitt bearings
5. Precision mechanical processing
6. Sulzer Turbo Services representative
      The application range of paint spraying can be classified as follows:
+ Spray paint to restore machine parts
+ Spray paint to protect metal structures
+ Spraying special coatings with high material costs: wear-resistant, anti-corrosion, heat-resistant...
+ Spray paint (electrical conductive paint, good thermal conductivity paint, magnetic paint...) on parts where the base material does not have these properties.
+ Repair defects of castings.
With the motto of improving the quality of equipment maintenance services in Vietnamese industry, gradually replacing Vietnamese services that have to be sent abroad for repair, the team of engineers and staff of Quang Khanh Company have boldly researched Research and application of paint spraying technology for Vietnam's mechanical industry. industry. maintenance market.
We have used equipment from advanced countries around the world such as:
1, Israeli HVOF and air injection equipment,
2. Metal powder raw materials from SulzerMetco company, is the world's leading manufacturer of raw materials for paint spraying technology.
We are committed to meeting all metal spraying needs with the best quality and competitive prices for industries: oil and gas, turbine power generation, aviation, transportation, chemicals, printing industry, metal heat treatment,....
