Take Changzhou Glibo Tools Co., Ltd. as an example:
The company has 30 assembly lines and three sub-factories: injection molding plant, motor plant, stamping and plastic spraying plant, and there are four technical research and development departments and one engineering department, which are specialized in research and development of new products.
The motor workshop has five rotor lines and four stator lines, the motor production line is highly mechanized, automated, and has advanced welding equipment, etc., which is in the leading position in the same industry in China. The stamping and plastic spraying plant has three 325-ton and two 500-ton stamping presses and automatic plastic spraying lines.

Electrostatic spraying process. p>Electrostatic spraying process
1, pre-treatment:
Purpose: remove oil, dust, rust on the surface of the workpiece, and generate a layer of corrosion resistance on the surface of the workpiece and can increase the adhesion of the spray coating of the "phosphate layer".
The main process steps: degreasing, descaling, phosphating, passivation. Workpiece after pretreatment not only no oil, rust, dust, and the original silver-white glossy surface to generate a layer of uniform and rough not easy to rust gray phosphate film, both rust and increase the adhesion of the spray coating.
2, electrostatic spraying
Purpose: the powder coating evenly sprayed onto the surface of the workpiece, special workpiece (including easy to generate static shielding position) should be used to complete the spraying of high-performance electrostatic spraying machine.
Process steps:
Using the principle of electrostatic adsorption, the surface of the workpiece is evenly sprayed with a layer of powder coating;
The falling powder is recovered through the recycling system, and it can be reused after sieving.
3, high-temperature curing
Purpose: The powder coating on the surface of the workpiece is heated to the specified temperature and held for a corresponding period of time, so as to make it melt, leveling, curing, so as to get the surface effect of the workpiece we want.
Process steps: the sprayed workpiece is pushed into the curing furnace, heated to a predetermined temperature (generally 185 degrees), and held for a corresponding period of time (15 minutes); open the furnace and remove the cooled to obtain the finished product. General workpiece is different, heating temperature and holding time is also different.
Tips: heating and control system (including electric heating, fuel, gas, coal and other heating methods) + insulation box = curing furnace.
4, out of the cooling
Out of the cooling is the result of the plastic spraying process is cooled to return to the normal temperature of a process.
5, decorative treatment
Purpose: after electrostatic spraying the workpiece to achieve a special appearance effect such as: a variety of wood grain, pattern, lightening and so on.
Process steps: cover light; transfer printing and other treatment processes.
