Gaoding automated finishing equipment and continuous coating lines

Qingdao GODN Mechanical Technology Co., Ltd. has developed and manufactured industrial automated finishing machinery under Gaoding and GODN brands since 1999.

Located in the industrial cluster of Qingdao, the enterprise produces five-axis CNC spray finishing centers, throughfeed reciprocating lines and drying tunnels.

The machinery is widely utilized in the manufacturing of solid wood doors, MDF cabinetry doors, furniture boards, architectural panels and wall slabs.

The engineering design of Gaoding finishing complexes is tailored for continuous multi-shift operation in demanding factory environments. The equipment employs precision servo drives, chemical-resistant stainless fluid circuits and air filtration manifolds.

Automated production lines standardize coating film thickness, lower paint consumption and eliminate manual labor in critical surface finishing operations.

Gaoding five-axis CNC spray finishing centers of the SPD series

Flagship Gaoding five-axis CNC finishing machines of series SPD2500D and SPD3000D-3D are built for precision automatic finishing of workpieces with complex geometry. The machine features an infeed optical scanning unit that reads workpiece dimensions, outer edges and routed inner grooves.

The software computes the optimum spray gun toolpaths, nozzle orientation angles and trigger timings for smooth material flow.

The kinematic motion of the five-axis manipulator enables thorough coverage of deep recessed profiles, decorative bevels and edge details without runs or sag defects. The application enclosure features positive draft ventilation and multistage aerosol separation.

Machine control relies on an industrial PC terminal with a color touch screen supporting program recipes and fast job changeovers.

Throughfeed reciprocating coating lines and lacquer recovery systems

For high-volume production of flat panels and door slabs, Gaoding produces throughfeed automated lines equipped with reciprocating or rotary spray arms. Workpieces travel along a powered conveyor through a rotary de-dusting brush module before entering the enclosed spray chamber.

The oscillating carriage moves across the line, delivering overlapping spray patterns across the full working width.

A primary advantage of Gaoding throughfeed lines is the closed-loop belt cleaning and material recovery mechanism achieving up to 98% efficiency. Stainless doctor blades scrape overspray from the conveyor belt into collection tanks for filtration and reuse.

Subsequent roller solvent cleaning prevents transfer of residual paint to the reverse side of moving furniture components.

Convection hot air drying tunnels and ultraviolet curing stations

Controlled drying forms an integral step in the finishing workflow on Gaoding automated lines. Throughfeed hot air convection tunnels feature multi-zone temperature regulation, laminar air distribution and thermal energy recirculation.

The initial section allows gentle solvent flash-off without bubbling, while subsequent zones achieve full cure of primers and polyurethane lacquers.

To polymerize UV-reactive formulations, Gaoding integrates ultraviolet curing stations into continuous lines. These units feature high-intensity UV lamps with elliptical reflectors and step-free power adjustment.

Radiation cures applied lacquer films within seconds, producing hard, scratch-resistant surfaces ready for immediate intermediate sanding or packaging.

Preventive maintenance protocols, spray guns and filtration care

Consistent operation of Gaoding finishing lines requires adherence to factory maintenance schedules. Operators perform daily solvent purging of automatic spray guns, fluid nozzles and feed hoses, clean optical scanner lenses and inspect exhaust dry filters.

Factory manuals forbid clearing nozzle orifices with metal tools, recommending solvent soaking and compressed air blowing.

Scheduled servicing includes checking reciprocating drive belts, tensioning carriage timing belts, lubricating linear guide rails and verifying diaphragm pump seals. Infeed ceiling filter media and water curtain reservoirs are checked weekly.

Timely replacement of worn fluid needles, nozzle seals and valves prevents dripping and surface blemishes on finished panels.

Component selection and spare parts supply by factory nameplate

We supply replacement components, assemblies and wear parts for Gaoding finishing machines and automated lines.

Using a photo of the equipment nameplate, serial number or spare part designation, engineers identify spray nozzles, air caps, pneumatic diaphragm pumps, servo drives, sensors, conveyor belts and recovery blades for full mechanical compatibility.
