Automatic Spray Coating Lines Overview
Automatic spray coating lines are MUSI's flagship product line, with 300+ installations running stably worldwide. We provide end-to-end services from workpiece analysis, line layout design, equipment manufacturing, installation, commissioning, to operator training. MUSI Technology designs and manufactures these lines in Changzhou, China, and has delivered 800+ coating lines to 36 countries; overhead-chain lines run at 0.5–5 m/min with line lengths of 60–150 m.
Overhead chain, floor belt, and robotic flexible spray coating lines for high-volume automotive parts, appliance, and hardware production. Capacity ranges from 8,000 to 30,000 pieces per shift.
An automatic spray coating line is a conveyorised production line that carries each workpiece through pretreatment, spraying, curing and cooling without manual handling between stages. Line speed, part spacing and oven length are calculated together, so every part receives the same dwell time and the same film build.
MUSI builds five configurations. Overhead chain lines suit hardware, automotive small parts, lighting and appliance shells. Floor belt conveyor lines carry furniture, flat sheet metal and large machinery parts up to 500 kg per station. Reciprocator lines coat door and window profiles and aluminium extrusions. Robotic flexible lines handle complex workpieces such as EV battery housings, and modular combined lines let a plant add capacity in stages.
Overhead chain lines run at 0.5–5 m/min and take workpieces up to 2,500 × 800 × 1,500 mm. Reciprocator lines hold film thickness to ±5 µm, and robotic lines reach ±3 µm with 80–95% paint transfer efficiency. Total installed line length is 60–200 m (60–150 m on overhead chain lines, 80–200 m on floor belt lines), and modular lines scale from 5,000 to 50,000 pieces per shift.
Key components are available from international brands such as Siemens and Schneider Electric (PLC and electrical control), SEW-EURODRIVE (conveyor drives), ABB, KUKA and FANUC (robots), and international tier-one spray gun brands (spray equipment), configurable per customer specification. Standard configurations ship in 30-60 days with a 12-month full-machine and 36-month critical-component warranty, and installation, commissioning and operator training are carried out on site. Structural parts are covered for up to 60 months.

Models in This Category
Overhead Chain Spray Line
Suspended overhead conveyor system that transports workpieces through pretreatment, spraying, curing, and cooling stages — ideal for high-volume small-part coating.
Floor Belt Conveyor Spray Line
Workpieces placed flat on a powered belt conveyor — high load capacity, ideal for furniture panels, large castings, and flat metal sheets.
Reciprocator Spray Line
Vertical or horizontal reciprocator carriages with spray guns moving in regular patterns — paired with workpiece conveyance for uniform coating coverage.
Robotic Flexible Coating Line
Equipped with ABB / KUKA / FANUC 6-axis industrial robots with vision recognition and offline programming — high-precision automatic coating for complex workpieces.
Modular Combined Spray Line
Standardized modular design — pretreatment, spraying, curing, and cooling modules combine flexibly, enabling capacity expansion and process upgrades over time.
Selection Considerations
Different models target different applications and capacities. Before purchasing, please consider:
- Workpiece characteristics — size, weight, geometry (flat / 3D), material (metal / plastic / wood)
- Coating type — powder / liquid / UV / 2K, etc.
- Capacity needs — shift output, cycle time, multi-color requirements
- Facility conditions — available area, ceiling height, electrical/gas supply, emission requirements
- Budget — balance of upfront investment and long-term running cost
