Brand tag temperature of electrophoresis rack

The term “Brand tag electrophoresis lattice” is not a common term in the industry, but in conjunction with the “electrophoresis lattice” related process, the temperature control needs to be determined according to the specific type of process and equipment requirements. The following is the possible temperature range and analysis:

Electrophoresis process temperature

Conventional electrophoresis

We controll the temperature of the electrophoresis bath at 25°C to 30°C to make sure a uniform and dense electrophoresis film. Too high a temperature may cause the paint film to hang, and too low a temperature may affect the reaction rate of electrophoresis.

Low temperature electrophoresis

For some special processes ( low-temperature curing electrophoresis paint),we should control the bath temperature at 15°C to 20°C to match the low-temperature curing system.

Curing temperature of the frame (coating)

Heat curing

If “lattice” refers to the curing of the coating after electrophoresis, the temperature is usually 160°C to 180°C and the time is 20 to 30 minutes, depending on the type of electrophoresis paint ( epoxy, polyester).

UV curing

We use UV curing to instantly cure coatings without heat, relying on a UV light source instead

Equipment operating temperature

Electrophoresis tank

We should equip with a temperature control system in tank to ensure that the temperature of the tank liquid is stabilized within the range of process requirements, with a fluctuation of no more than ±2°C.

Curing equipment

The temperature of curing oven should be uniform, and the temperature difference should not exceed ±5°C to avoid uneven coating quality.

Special process temperature

Low temperature electrophoresis + high temperature curing

Some processes may use low-temperature electrophoresis with high-temperature curing , and the temperature control of the electrophoresis and curing stages should be strictly differentiated.

Rapid curing

Some high solids electrophoresis paints may support low temperature rapid curing from 140°C to 150°C to shorten the production cycle.

Temperature Control Recommendations

Accurate Temperature Control

Use high-precision temperature controllers to ensure the temperature of the electrophoresis bath and curing oven is stable.

Pre-heating

Before electrophoresis,we should preheat the workpiece at 20°C to 30°C to minimize the temperature fluctuation of the bath.

Cooling system

After curing, we should aquip a cooling device to avoid overheating of the workpiece which may lead to deformation.

Conclusion

We detaermine the temperature of the “Brand tag electrophoresis rack” according to the specific process and equipment requirements. Recommendation:

Check the equipment manual or process documentation for temperature parameters.
Contact the electrophoresis paint supplier for recommended process temperatures.
Regularly calibrate the temperature control equipment to ensure the accuracy of temperature control.
