Fully Automatic Electrostatic Powder Coating Line

1. Basic Technical Parameters

1.1 Workpiece Specification

1.2 Production Process Flow

Loading → Multi-stage spray rinsing → Pre-degreasing → Main degreasing → Multiple pure water rinsing → Titanizing treatment → Final pure water spray → Hot air dehydration drying → Natural cooling → Automatic electrostatic powder coating + manual touch-up spraying → High-temperature powder curing → Cooling → Unloading. Total 17 working stations with counter-flow water supplement design to save water and reduce wastewater discharge.

2. Detailed Configuration of Each Section

2.1 Spray Pre-treatment System

9 spraying stations in total. Side & top panels made of SUS304 stainless steel （1.38mm）, bottom plate 2.0mm fully argon welded against liquid leakage. Pre & main degreasing tanks adopt double-layer insulation with 50mm rock wool filling.

Full SUS304 spraying pipeline equipped with quick-detachable PP V-type nozzles, working pressure 0.1~0.15MPa. Configured with 200μm bag filter, automatic chemical dosing pump, auto water replenish & high/low liquid level alarm system （pump auto stop at low level）. FRP exhaust fan installed at degreasing section to discharge acid mist.

Circulation pumps from Nanfang Pump & Ruichi Pump, separated chemical resistant pumps & water pumps for different solutions. FRP maintenance walkway, multiple access doors and LED inspection lamps installed alongside tanks; inclined tank bottom for convenient sludge draining.

2.2 Dehydration Oven & Curing Oven

Independent gas-fired drying & curing ovens with composite insulated structure. Side wall total insulation thickness 170mm, double-layer rock wool ceiling 200mm（density:120kg/m³） for outstanding heat preservation and gas saving.

Equipped with American E-brand proportional gas burner, bottom air supply & internal circulation design, temperature deviation ≤±5℃ inside effective working zone. PT100 multi-point thermal resistance + imported temperature controller; gas supply cut-off & sound-light alarm for over-temperature. High-temperature filter inside curing combustion chamber to avoid dust pollution. Waste gas discharged via high chimney to meet environmental standard.

2.3 Closed Powder Coating Booth & Clean Isolation Room

15m×7m×7m dust-proof isolation room constructed by 50mm rock wool sandwich panels, with 50mm hollow tempered glass observation window and explosion-proof clean lamp （600lux illumination）.

Integrated PP-made spray booth matched with big cyclone + cartridge dual-stage powder recovery system, 5.5KW explosion-proof exhaust fan and 2 sets automatic electrostatic spray guns. Automatic reciprocate spraying plus manual touch-up at both ends; excess powder recycled for reuse to lower raw material cost.

2.4 GX250 Enclosed Overhead Conveyor

Closed-loop GX250 overhead conveyor, chain pitch 250mm, track size 80×80mm; single point load 50KG, max 100KG for double-point hanger.

The track can turn horizontally and climb up/down vertically, smoothly pass through pre-treatment, oven and coating booth with stable low-noise operation for continuous mass production.

2.5 Waste Gas & Wastewater Treatment

Curing oven exhaust discharged via high chimney; pre-treatment wastewater collected by client’s independent wastewater facility. Shock absorption & silencer fitted on high-noise fans & pumps to ensure factory noise below 85dB (Class III). All liquid-contacting parts adopt anti-corrosion stainless steel.

2.6 PLC Intelligent Control System

Controlled by Mitsubishi PLC + 12-inch industrial touch panel, manual/automatic switchable with interlock program among pre-treatment, drying, conveyor and coating sections. Multi-protection functions: motor overload & phase loss protection, tank liquid level alarm, oven high/low temperature fault alarm & emergency stop. Control cabinet with internal heat dissipation design, 10% spare I/O ports reserved for future upgrade, compatible with Russian 380V/50Hz power supply standard.
