Powder oven (powder curing furnace) is a kind of industrial equipment used for powder coating curing treatment. Through high temperature heating, the powder coating sprayed on the surface of the workpiece can melt, flow flat and solidify into a film, which is widely used in the metal surface coating industry. Here is a detailed description:
1. * * Powder curing * *
-Heat the sprayed workpiece to a set temperature (usually 120 C~220 C) so that the powder coating has a chemical reaction (crosslinked curing) to form a uniform, durable coating.
2. * * Improve the coating performance * *
-The cured coating has wear resistance, corrosion resistance and ultraviolet resistance, and is suitable for outdoor or harsh environment.
1. * * Heating system * *
- ** Heating mode * *: electric heating (resistance wire, infrared wire), gas heating (natural gas, liquefied gas) or fuel heating.
- ** Hot air cycle * *: evenly distribute the heat through the fan to avoid the local temperature difference.
2. * * Temperature control system * *
- ** Intelligent temperature control * *: PLC or PID control, accurate adjustment of temperature (within ± 2 C).
- ** Multi-zone temperature control * *: divided into preheating area, curing area and cooling area, to meet the needs of different curing stages.
3. * * Delivery System * *
- ** Delivery mode * *: chain type, net belt type or hanging chain, adapt to different shapes of the workpiece (such as sheet metal parts, pipes, hardware).
4. * * Safety design * *
-Explosion-proof device, overtemperature alarm, power-off protection to ensure safe operation.
-Waste gas treatment system (such as activated carbon adsorption, catalytic combustion), reduce VOCs emissions.

### ** III. Technical parameters * *
- ** Temperature range * *: 120 C~250 C (adjusted according to the powder type).
- ** Heating efficiency * *: The heating time is usually 15~60 minutes (depending on the size of the furnace body).
- ** Energy consumption * *: electric heating is about 30~150kW / h, gas type is more energy saving.
- ** Applicable workpiece size * *: can be customized, common furnace cavity size 1m 1m 2m to large continuous production line.

### ** IV. Application fields * *
1. * * Automobile manufacturing * *: powder coating of car body, wheel hub and engine parts.
2. * * Home appliance industry * *: Anti-corrosion and decorative coating of refrigerator, air conditioner and washing machine shell.
3. * * Building materials and furniture * *: surface treatment of aluminum profiles, anti-theft doors and metal furniture.
4. * * Electronic equipment * *: Insulation and protection of precision parts such as chassis and radiators.

### ** V. Advantages and characteristics * *
1. * * Environmental protection * *: powder coating without solvent, curing process is almost no harmful gas emissions.
2. * * High efficiency * *: Automatic assembly line design, can be continuous operation, save labor.
3. * * Low cost * *: The powder utilization rate is as high as 95%, reducing material waste.
4. * * Coating quality * *: uniform color, strong adhesion, better than the traditional paint process.
Yes; the coating bubbles shall be checked for powder water content.
