Dalian Powder Coating Selection Guide: Comprehensive Guide to Equipment, Process, and Maintenance Points 

The efficient application of powder coating in Dalian cannot be achieved without reasonable equipment selection, suitable process solutions, and scientific maintenance management. Whether it's building a new production line or upgrading it, mastering the following key points can help you easily deal with purchasing difficulties.

Equipment selection is the foundation of powder coating. As the core component, the spray gun needs to be selected according to the size of the workpiece and coating requirements. Compact spray guns with built-in electrostatic generators are suitable for small workpieces to ensure precise powder adsorption; Large workpieces require long gun bodies with high output power to ensure spraying efficiency. In terms of powder supply system, if the production volume is large, a fluidized bed powder supply device can be selected, and its uniform and stable powder supply capacity can meet the continuous operation requirements; In intermittent production scenarios, small powder storage tanks paired with Venturi pumps are more cost-effective. In addition, the size and heating method (electric heating or gas heating) of the curing furnace should be matched with the workpiece size and production cycle to avoid energy waste.

 

The process plan needs to be tailored to actual needs. For workpieces with complex surfaces, electrostatic friction spraying technology should be chosen to reduce dead corner powder accumulation; If pursuing high gloss and high flatness coating effects, electrostatic powder spraying combined with leveling process is a better choice. At the same time, adjust the spraying parameters according to the material of the workpiece, such as setting a higher electrostatic voltage to enhance the adsorption force for metal parts, and controlling the temperature to prevent deformation for plastic parts.

Maintenance management determines the service life and coating quality of equipment. Regularly clean the spray gun and recycling system in daily life to prevent powder clumping and blockage; Check the voltage stability of the electrostatic generator every month to ensure the adsorption effect. Calibrate the temperature control system of the curing furnace every quarter to avoid a decrease in coating performance due to temperature deviation. In addition, establish a powder coating inventory management system and store them by batch and shelf life to prevent the powder from getting damp and deteriorating.

To achieve the dual goals of efficient production and high-quality coating, it is necessary to comprehensively control every aspect of powder coating, from equipment to process, from installation to maintenance.
