This article explains the core differences between the Swinger Powder Coating System and Electrostatic Spray Guns. The Swinger system automates powder coating with multi-gun, mechanical swinging arms ideal for durable, high-volume finishing requiring heat curing. In contrast, electrostatic spray guns use charged liquid paint for high transfer efficiency and detailed applications without heat. Understanding their unique features helps choose the right technology based on coating material, application needs, efficiency, and environment.
