Auto hot dip powder coating machine WIND-HDP

Resin coating powder coating machine for motorcycle stators WIND-HDP apply the resin to an electrical motor armature or stator which has been heated to a temperature above the melting point of the resin.

On contat with the preheated application surface, the resin melts, flows to a controlled extent, then cures, bonding to the substrate and coalescing into a smooth, continuous,essentially uniform, thick coating.

I. Design and production reference

II. Working process

1. Fix the stator (work piece) in the fixture, then put it inside the inductorium,

2. Power on the machine, then the induction heater automatically

begin working, the heat time could be set, when set time is reach heater

automatically stop, Normally the heater time is 10s

3. Fetch out the fixture,then dip both side in the power coating station,

the stator is hot, and the fixture is in normal temperature and won’t burn you,

4. Dip the fixture in the power coating station both side, the dipping time is

depend on stator stack thickness and powder’s character,

For example,normally one side is 3s, then the other side 2s

5. After dipping, disassemble the fixture clean the fixture using a air gun to

remove the remain power when necessary

6. Collect and put the stators into oven( the machine didn’t contain an oven with it),

The oven temperature need reach to 180～200℃

(depended on powder’s character), keep that temperature for more than 30 minutes

III.Machine feature

1. Machine is composed of heating,powder coating,powder cleaner and

powder recycle system with nice appearance and reasonable configuration,

the machine frame is made of 1.2mm A3 steel plate,

2. High frequency indution heater have the advantage of fast heating,

low energy, safety and reliability

3. Air blowing ensure well done in cleaning fixtures

4. Cooling on high frequency induction heater is freezing style water cooler

tank, it is well cooling

IV Machine configuration

Machine dimension  L2100×W1720×H2100 mm

During the fluidized bed coating, an electrical motor stator or armature is dipped in an adhesive bath, dried and pre-heated. It passes into a bath with fluidized powder which acts like a liquid when air is forced through the powder bed. This covers the wire surface with powder that melts on the substrate due to the preheating of the substrate. This is followed by after-curing or after-fusion of the polymer, and fan cooling. Panels and post objects undergo a more complex electrostatic powder coating process that starts with up to 10 stages of pre-treatment ( zinc-phosphatation).
