Spray painting machines are compatible with many mainstream coatings, including water-based, solvent-based, and oil-based paints, as well as UV paint and others.

Viscosity varies depending on the type and brand of coating, as well as ambient temperature and humidity. For example, when spraying UV primer under subtropical monsoon climate conditions at 30 degrees north latitude, the viscosity should be 11-13 seconds, measured with an Iwata viscosity cup No. 2; in winter, it should be adjusted to 11-16 seconds. Our experienced after-sales engineers will take your specific circumstances into account, adjust the coating to the appropriate viscosity on-site, and provide professional operating instructions.

After daily work, the pump, pipelines, spray gun, and worktable should be thoroughly cleaned. First, place the suction tube of the pump into a clean solvent container, adjust the pump pressure to 0.1-0.15 MPa, and the atomizing pressure to 0 MPa; then move the spray gun to a suitable cleaning position and activate the spraying until clean solvent is sprayed out; after returning the spray gun to its original position and turning off the power, manually remove the nozzle and atomizing cap and soak them in clean alcohol. This will make the spray gun look brand new. Some models support one-button automatic cleaning of the spray gun. It's important to regularly add lubricating oil to the automatic oiler and the plunger pump every week to ensure a longer service life for the spray painting machine.

In addition, our after-sales engineers will provide you with detailed tutorial videos for your spray painting machines or guide your workers to fully master the equipment’s cleaning and maintenance methods by accompanying them during production.

We will provide detailed DWG installation layout drawings for the spray painting machine based on your available space. Some models come with built-in positive-pressure air systems, water curtain systems, and paint recovery and filtration devices, which have significantly improved paint utilization and reduced paint mist dispersion. However, to ensure perfect coating results and comply with industrial coating environmental requirements, we still recommend building a professional pressurized spray booth and connecting it to equipment and a VOC treatment device via pipelines to centrally collect VOC generated by each process. Finally, these VOCs should be treated using methods such as activated carbon adsorption, photocatalytic oxidation, or secondary combustion to achieve environmentally compliant emissions. If this is unfamiliar to you, as a one-stop service provider, we would be honored to offer you comprehensive solutions. Please contact us for more details.

If the processed materials have uneven coating, you can troubleshoot and solve the problem from the following aspects:

First, check the paint supply system to ensure that the paint pressure is stable and that there is no blockage in the pipeline, as an unstable paint supply will directly lead to uneven coating thickness.

Second, adjust the conveyor speed and the coating nozzle distance; if the speed is too fast or the nozzle is too far away, the paint coverage will be uneven.

Third, check the surface of the processed material. If the raw material surface has dust, oil stains, or unevenness, it will affect paint adhesion and spreading, so pre-cleaning or leveling of the raw material is required.

Fourth, verify the drying or curing temperature; if it is too low or uneven, the coating may flow before curing, resulting in unevenness.

If the above methods don’t work, it may be a problem with the spray painting machine's nozzle precision. Please contact the manufacturer for maintenance or replacement.
