What is coating facility?

With the advancement of science and technology, synthetic coatings using synthetic high molecular substances are widely applied throughout modern industries. The functions of coating include weatherability, corrosion resistance, prevention of adhesion of foreign bodies, heat insulation and smooth appearance. They are closely related with our life. The attention on eco-friendly coatings such as water soluble coatings and high solid coatings is increasing. In response to this, we are focusing on coating facility sector demanded by customers based on technology and experience accumulated over 20 years.

Coating Procedure

This equipment removes dirt and cleans the surface of vehicle body using chemical treatment. This procedure prepares for the optimum coating spray condition. Based on our experience in facilities for completed vehicles and automobile parts, we are taking responsibility in supplying preprocessing equipment suitable for the properties of object by taking consideration of customer demand from designing to production, installation, test operation and maintenance.

This coating method is used to coat a workpiece by setting the workpiece and tank as electrodes on each side and flowing current into water soluble paint inside the tank. It has less coating loss compared to immersion coating or spray coating. Also, automated process and coat reduction can reduce raw cost. As the undercoat (corrosion-proof coating) in completed vehicle industry and parts companies, the accessories include U.F. (Ultra Filtation) equipment and anode sell device.

This equipment is used to cure the coating on the surface of vehicle by using hot air. This process is important as it influences the coating quality. Air inside drying furnace is circulated by force to increase the air temperature inside the furnace by using heaters (gas, steam or electric heaters, etc.) during circulation. Its biggest advantages include possibility of uniform drying coating, wide temperature control range, and variety of heat sources. As it can be influenced by external factors, designing, production and installation are especially important.

This facility is used for paint spraying onto the surface of vehicles. In this important process, various factors such as temperature, humidity and dust prevention influence the coating efficiency. Depending on coating type, special auxiliary facilities are needed.
Auxiliary Facilities: A/C Tower, C.W.S., Exhaust System, Air Handling Unit, etc.
Booth Types: Spray Booth (Primer, Topcoat, Powder), Repair Booth Polishing, etc.

This equipment is used to supply air inside spray booth and working area to optimum condition necessary for coating procedure. Coating quality is influenced by surrounding environment, hence to assure supply of suitable air quality, a precide A.H.U. is essential. Its precise temperature and humidity control and dust removal function influence the coating quality.
Components of A.H.U.: Roll Filter, Heat Source (Gas Burner or Steam Coil), Washing Zone, Cooling Coil, Supply Fan, etc.

Coating Facility/Installation Case

STEP1. Design
  • Initial design step: Reflect problems in existing plant facility
  • After basic designing, review facility operability/workability/preservation
  • Review details production design drawing: Structural durability (to prevent production defect)

Specification Consulting
