An automatic electrostatic powder coating line is a production system that applies dry powder paint to metal (and some non-metal) parts using electrostatic charge, then cures the coating in an oven. It combines pretreatment, powder application, recovery, conveyor transport and curing into a continuous or semi-continuous workflow for consistent, high-quality finishes.
Typical components are a pretreatment system (dip tank or spray), conveyor/transfer system (manual or fully automatic, ground rail if required), electrostatic powder spray booths and guns, powder recovery system (cyclone + secondary filter or simple filter), curing oven (tunnel, bridge or box), control cabinets, and all necessary piping, fixtures and 3D assembly drawings.
We analyze the customer's budget, production capacity, workpiece weight, size, shape and handling needs. Manual delivery is cost-effective for low-volume or large/irregular parts; fully automatic conveyors are chosen for higher throughput, consistent cycle times and smaller standardized parts.
Ground rail mode uses floor-mounted rails to transport heavy or bulky parts reliably. It is recommended when workpieces are large, heavy, or oddly shaped and when a robust, low-maintenance transport method with flexible run length is required.
We offer dip tank (immersion) and spray pretreatment systems. Pretreatment removes oils, rust and contaminants and activates the surface to improve powder adhesion, corrosion resistance and coating longevity. Choice depends on part geometry, throughput and environmental requirements.
Options include a cyclone with secondary filter recovery for high-efficiency reclaim and minimal dust emissions, or a simpler filter recovery for lower-cost installations. Cyclone systems recover more overspray and are best for frequent color changes and higher material savings.
We supply tunnel ovens for continuous throughput, bridge ovens for medium throughput or special layouts, and box ovens for batch or large single-piece curing. Selection depends on line layout, part heat tolerance and production rate.
Yes. We design the whole line to minimize workshop footprint and adapt transport routes and oven lengths to your part sizes and production flow. All details are confirmed with client-provided specifications and 3D assembly drawings are provided to aid installation.
Yes. The line is assembled and tested at our facility before delivery. Clients are welcome to visit for inspection and witnessing of tests. We also provide 3D drawings and coordinated delivery schedules to ensure timely installation.
Color change time depends on the recovery system and booth layout. Systems with efficient cyclone recovery, dedicated color change procedures and proper booth design can achieve fast color changes by minimizing residual powder and enabling quick cleaning cycles.
Routine maintenance includes cleaning and replacing filters, checking powder guns and hoppers, inspecting conveyors and oven elements, and periodic calibration of controls. Operating costs include powder material, energy for ovens and conveyors, consumables (filters, nozzles) and occasional spare parts. We design for low maintenance and provide a recommended maintenance schedule.
We provide powder recovery systems and filtration to minimize airborne powder and emissions, enclosed booths to reduce overspray, proper ventilation and explosion-proof electrical components as needed. Safety interlocks, CE/UL-compliant controls and operator training are part of the standard offering.
Lead time depends on scope and customization; typical planning, fabrication, testing and delivery schedules are provided after specification confirmation. We arrange shipping and can coordinate installation timelines to meet client requirements, with advance scheduling to ensure on-time delivery.
Yes. We offer on-site installation and commissioning services, pre-shipment assembly guidance via 3D drawings, and operator/maintenance training to ensure safe, efficient operation. Ongoing technical support and spare parts supply are available.
