Automatic Powder Coating Machine for Lock Surface Spraying in Hardware Production Line

This 500X7A seven-axis automatic spray painting machine is purpose-built for high-efficiency surface coating of locks and hardware components in an automated production line. Combining 360-degree high-speed rotary spraying with reciprocating spraying and two independently dispensing guns, it delivers uniform film thickness and complete coverage of lock bodies, face plates and hardware fittings at +/-0.05mm positioning accuracy. The dual rotating stations (T1 / T2) and rotary base (W axis) enable continuous, automated coating with a consistent, defect-free finish.

• Seven-Axis Precision Closed-Loop Stepper Drive: X, Y, Z, R, T1, T2 and W axes work together to provide stable, repeatable coating paths with +/-0.05mm accuracy, keeping film thickness consistent across every lock body and hardware component.
• 360-Degree High-Speed Rotary + Reciprocating Spraying: Rotary spraying combined with reciprocating motion fully covers the flat surfaces, edges and recessed details of lock bodies, eliminating blind spots and costly touch-up rework.
• Two Independently Dispensing Spray Guns: Each Mansheng blue gun controls its own paint output, allowing simultaneous coating of large surfaces and edges with reduced overspray and paint waste.
• Dual-Station Rotation (T1 / T2): The A and B working stations rotate in turn for fast loading and unloading, enabling continuous, high-throughput automated coating of hardware lock parts.
• Mansheng Touchscreen Control Series: Intuitive touchscreen operation with 10,000-level program storage and USB communication port for quick recipe switching and mass production.
• Premium Branded Components: HIWIN guide rails, NSK bearings, Leadshine motors, Hugong power supply and CHINT, DELIXI, OMRON electrical components guarantee long-term reliability and consistent coating quality.

Ideal for automatic surface coating of door locks, padlocks, cylindrical and mortise lock bodies, face plates, hinges and other hardware components. Also suitable for spraying metal structural parts and small-to-medium metal workpieces. Supports water-based and oil-based industrial paint systems as well as powder coating processes for metal substrates.
