2018 Forplan MKS800R Automatic Dip-Spin Coating Line for Zinc Flake Coating of Bulk Parts

MACHINE: Fully automatic dip-spin coating line (basket coating line) with continuous gas-fired dryer, cooling zone and PLC control.

CONDITION: Used.

APPLICATION: Coating of flowable, conveyable metal bulk parts made of steel or zinc die-cast with solvent-based MKS coating materials (base coat and top coat, for example zinc flake coatings). Suitable parts: flat stamped parts, stamped and bent parts, springs and threaded parts. Reference part: M8 x 80 mm screw. Part size from 4 mm diameter up to 150 mm length. Maximum weight per piece 100 g.

OUTPUT: 3,000 kg/h at a cycle time of 4 minutes (adjustable). At least 15 baskets per hour.

BASKETS: 800 mm diameter, 540 mm height. Maximum load 200 kg per basket. Volume 90 litres (vertical) or 75 litres (tilted at 50 degrees). Stainless steel AISI 304 with mesh bottom (2.5 x 2.5 mm). 18 coating baskets and 7 cooling baskets included.

COATING PROCESS: Baskets are dipped straight or tilted at 50 degrees into the coating tank and can be rotated left and right for even wetting. Excess coating is removed by spinning at up to 300 rpm directly in the tank.

COATING TANKS: 4 dip tanks, stainless steel AISI 304, with cooling jacket and temperature monitoring. 3 volume-optimized tanks of approximately 130 litres for tilted dipping and 1 cylindrical tank of approximately 380 litres. Each tank has a pneumatic diaphragm pump with magnetic and bag filter. Set up for four Dörken Delta coating materials (Delta-Protekt KL 100, Delta silver, Delta-Seal black, Delta-Protekt VH 301).

DRYER: Continuous dryer, directly heated with natural gas, with modulating Weishaupt burner (90 to 350 kW) and a heating capacity of up to 330 kW. Flash-off and pre-drying zone (approximately 12 minutes), intermediate zone (approximately 4 minutes) and curing zone at 100 to 250 degrees C (approximately 36 minutes: 16 minutes heating and 20 minutes holding). Chain conveyor with perforated product containers (3 mm holes). Gas consumption maximum 32 cubic metres per hour.

COOLING: Cooling zone with a shuttle carrying 6 basket positions and nozzle ventilation. Two chillers of approximately 10 kW each.

LOADING: Lifting and tilting device for containers up to 1,200 x 800 x 1,000 mm and 1,500 kg. Belt hopper and dosing belt on weighing system with residual quantity optimization. Extra loading station for parts that tangle (containers up to 800 x 400 x 600 mm, 500 kg) with weighing platform and large digital display. 3 weighing systems in total. 5 drop-height reducers for gentle handling of the parts.

UNLOADING: Tilting, rotating and traversing discharge station. 2 height-adjustable discharge belts and 1 return belt for multiple coating cycles.

HANDLING: 3 overhead transfer carriages with lifting units and grippers, driven by frequency converters.

CONTROL: Siemens Simatic S7 PLC with PC and 15 inch colour touchscreen. 999 recipes, batch tracking of every basket load and process data logging to a CSV file (USB export).

BRANDED COMPONENTS: Siemens, SEW, Festo, JUMO, IFM, Schneider, Pepperl and Fuchs, Weishaupt.

ELECTRICAL DATA: 400 V three-phase with neutral and earth, control voltage 230 V and 24 V, 50 Hz. Total connected load approximately 90 kW.

COMPRESSED AIR: 6 bar, oil-free and condensate-free.

EXHAUST AIR: Approximately 3,000 cubic metres per hour of solvent-laden exhaust air.

INSTALLATION SIZE: Approximately 19,000 mm wide, 12,500 mm long and 6,500 mm high. Door opening to the installation site at least 4,000 mm wide and 3,480 mm high.

ENCLOSURE: Double-wall panel enclosure with safety door switches and emergency stop circuit. Noise level below 80 dB(A).

CE MARKED.
