Express Bicycle Rim Powder Coating Machine

         Spraying can be manual, automatic or manual + automatic. Spray material is 100% solid powder, 

              Step  1    About pre-treatment process, primatily to eliminate grease and dust on the workpiece.

              Step  2    Phosphating film drying, can next step to prepare for painting and  furthe inprove the resistance afetr

                               the coating film erodidbility.

              Step  3   The plastic powder by high voltage electrostatic charging device, and under the influence of an electric

                               field uniformly adsorbed on  the surface of the workpiece to be machined.

              Step  4    By heat treatment make high temperature curing , let the surface to form a high density coating.

              We use Wooden case package, wooden pallet, PE plastic film package etc.

                shipping is by train, by railway, by air. Lading port is Qingdao port and so on.

               1. Why does the product have color difference?

               The temperature of oven is nonuniform.

               2. Why does product appear nonuniform coating?

               A.  Powder gun can’t spray uniform coating.

               B.  The speed of chain and elevators do not match.

               C. thickness gauge to test the same product as per national standard,the thickness should be reached 60-75um.

               3.  Why coating will be fall off?

               A. Surface heavy oil, spraying stages are not enough, rinse is not clean.

               B. Lack in advanced return air system leading to the effective temperature range is not enough, the product is not

                   heating well.

              4. Why conventional coating equipment can’t achieve environmental protection standard?

              A. Powder spillover makes environmental pollution.

              B. Exhaust emissions from curing oven.
