electrostatic induction powder spraying customized for professional sheet metal processing is to use electrostatic powder spraying machine (machine equipment) to spray the paint on the surface of the workpiece. under the effect of electrostatic induction on the assembly line, the powder will be evenly adsorbed on the surface of the workpiece to produce a layer of powder coating, the assembly line will take the workpiece through the next process of continuous high-temperature baking drying and establish the final coating; the actual effect of spray coating is better than spraying in the fields of impact toughness, adhesion, corrosion resistance, anti-aging, etc., and the cost is better than spraying under the same actual effect.

The following are the steps of the electrostatic induction powder spraying process for the charging pile box:

1. solution before the surface of the box body: the sheet metal parts processing factory first ties the box body into the concrete tank or plastic welding tank to remove oil, rust, phosphating, passivation and other technological processes. After the box is solved, not only the surface is free of oil, rust, dust, etc., but also the original surface is glossy. Generally, a dark gray phosphating film will be produced after phosphating, which can not only prevent corrosion but also improve the adhesion of electrostatic spraying layer.

2. assembly line dusting electrostatic dusting hanging on the box: when hanging on the box, it is necessary to further wipe the particles on the surface with a pneumatic gun or other special tools, and then coat the surface of the box with a layer of plastic powder, using the basic principle of electrostatic adsorption, according to the recovery system to recover the falling plastic powder, after recycling can continue to use or sell the exhaust gas purifier.

3. continuous high-temperature baking and drying: the sprayed box will follow the assembly line through the high-temperature baking oven (if the oversized workpiece needs to be fed into an independent curing oven, also called bread baking oven), sheet metal processing manufacturers will heat up to the set ambient temperature (generally 185 C- 220 C), and the corresponding duration of heat insulation (5-15min is not sure according to the requirements); The finished product will be obtained after the furnace is discharged and cooled down, and the finished product will be refrigerated by the process flow immediately after the assembly line is completed.
