From dip paint to drop paint: Small change, big effect!

In the original dipping process, the paint tank was filled with resin insulating paint, and as the resin rose, the suspended stator was completely covered, and then the resin fell. Then three times of heating to promote the resin gel and curing, thus forming a complete stator dipping process. Among them, the process of resin flowing in and out will cause waste. In addition, multiple heating and curing processes are complex, occupy a large area, and consume time and energy.

Dipping process

So, how does the improved drop paint process exist? First, the stator is precisely fixed, and with the cooperation of the Siemens industrial control system and the industrial robot, the robot can move the resin drip nozzle to the desired position, so that the resin fills the entire stator drop by drop, thus greatly reducing the resin waste. Not only that, the drop paint process only needs to be heated once, and the use of inductance heating, fast, less energy consumption, carbon emissions are also reduced.

Paint drop process

From dipping to dropping, a process improvement resulted in four significant effects: the production unit’s footprint was reduced from 191 square meters to 35 square meters, the time required to produce a stator was reduced from 540 to 32 minutes, the electricity consumed was reduced from 2.58 KWH to 0.25 KWH, and the carbon emissions were reduced from 2.68 kg to 0.26 kg.
