FAQ

Q1: How long does it usually take to complete the drying process?

A: The drying time mainly depends on the type of coating material and metal thickness. Under normal conditions, conventional paints can be fully cured after baking at 140℃–180℃ for approximately 15–30 minutes.

Q2: What heating energy sources can be used? Which one is the most economical?

A: The equipment supports multiple heating methods, including:

Electric heating

Natural gas heating

Liquefied gas heating

Steam heating

For large-scale continuous production lines, natural gas heating is generally recommended due to lower operating costs. For small production facilities or areas with strict environmental requirements, electric heating is more convenient.

Q3: How does the equipment ensure the safety of paint solvent evaporation? Can it cause explosions?

A: The equipment is equipped with a forced exhaust ventilation system to continuously discharge volatile solvent gases. Optional safety configurations include combustible gas concentration monitoring devices and explosion-proof pressure relief doors to ensure safe operation.

Q4: What problems can uneven furnace temperature cause? How is it solved?

A: Uneven temperature distribution may cause:

Paint color differences

Coating bubbling

Incomplete curing

The equipment adopts a multi-section air guide plate design and powerful hot air circulation system to ensure temperature differences in different furnace areas are controlled within ±5℃.

Q5: Does the equipment support non-standard customization? What information is required?

A: Yes. The equipment can be fully customized according to customer requirements. The following information is required:

Maximum workpiece size and weight

Daily production capacity

Painting process requirements (curing temperature and time)
