Spray painting, powder coating, and electroplating are the most used appreance processing options in the manufacturing of metal insulated water bottles
Spraying painting
It is a method of applying to the surface of the object to be coated by means of a spray gun or atomizer, dispersed into uniform fine droplets by means of pressure or centrifugal force. Spray painting is safe to operate , and makes a colorfulflat and smooth surface.Its disadvabteges is :the painting process will produce harmful substances,the surface of the cup is easily scratched
Powder Coating
Powder Coating is sprayed on the parts through high-pressure electrostatic equipment. It is a safe and advanced technology, which can make a colorful surface, but by this method, the surface is not even.
Electroplating
The surface coating is removed by laser to reveal the stainless steel material. A durable and fast treatment for metal water bottle. However, compared with spray painting and podwer coating, it just provide one color making.
