The Spraying Station is a critical component of a Finishing Line, responsible for the precise application of liquid coatings, paints, sealants, or other finishing materials onto the surfaces of manufactured items. It typically follows cleaning or pretreatment stages and precedes drying or curing stages. Its role is to ensure uniform, controlled, and efficient deposition of the finishing material to achieve desired aesthetic, protective, or functional properties on the final product. The station operates by atomizing a liquid finishing material (e.g., paint, varnish, adhesive) using pressurized air (pneumatic), high pressure (airless), or electrostatic charge. The atomized spray is directed onto the target product, which may be stationary, conveyed through the station, or mounted on a rotating fixture, to achieve complete and even coverage. Parameters like spray pressure, nozzle type, fan pattern, and distance to target are controlled to optimize application quality and material usage. The station is typically constructed with stainless steel, aluminum alloy, and plastic components (e.g., PTFE for fluid paths). Key technical parameters include rated power (5.5–11 kW), operating pressure (1.0–1.6 MPa), spray flow rate (10–30 L/min per gun), spray width (300–800 mm), conveyor speed (0.5–5 m/min), coating thickness (20–120 μm per ISO 2808), temperature range (5–40 °C), humidity range (30–85 % RH), electrical supply (380 V AC ±10%, three-phase, 50/60 Hz per IEC 60038), air consumption (0.5–2.0 m³/min at 0.6 MPa per ISO 1217), noise level (≤85 dB(A) per ISO 11201), weight (1500–2500 kg), and footprint (5–10 m²). These values are reference ranges and must be verified for the specific model and application. Always confirm model-specific values and standards with the legal manufacturer or supplier.
