RPG two spray arm painting machine is a multi-station automated spray system designed for high-volume industrial coating purpose. Its core part is constructed by two sets of 6 axis spray arms but within a single support structure to achieve high-efficiency and consistent surface coating through synchronized reciprocating motion.
Painting Machine Structural Characteristics
- Multi-station parallel spraying: The equipment is configured with two spraying devices, allowing simultaneous spraying of 2 identical or similar workpieces, significantly increasing production capacity per unit time.
- Motion control system: Utilizes X/Y/Z three-axis linear motion + W/R rotary axis linkage to precisely control the spatial trajectory of each spray gun, adapting to flat, curved, and irregularly shaped workpieces.
- Integrated paint supply system: Equipped with central paint supply, pressure regulation, and atomization control modules, supporting various coating media such as water-based paints, solvent-based paints, and powder coatings.
- Intelligent programming: Supports teach-in programming and trajectory storage, allowing one-click switching of spraying parameters for different product models, enabling flexible production.
Technical Advantages and Application Scenarios
Efficiency improvement
Single-line daily production capacity can reach more than 5 times that of traditional manual spraying, and the cycle time can be reduced to 30 seconds/piece.
Cost savings
Paint utilization rate is increased by 30%~40%, and labor costs are reduced by more than 50%.
Stable quality: Spraying thickness deviation is controlled within ±5μm, and the color difference level reaches level 4 or higher, meeting automotive OEM standards.
For its extremely powerful design, its widely applicable for a variety of products spray production such as the following:
- Automotive parts: Such as wheel hubs, bumpers, door handles, interior parts, etc., for high-volume metal and plastic parts, including primer and topcoat spraying.
- Metal and plastic products: High-consistency appearance coating for power tool housings, home appliance panels, electronic connectors, etc.
From live production report, this robotic sprayer can significantly improves the spray painting pass rate to over 98%, reducing the manual touch-up rate by over 70%.

Double Spray Arm Painting Machine FAQ
Q: What’s the main difference comparing to other machines?
A: Its featured for the two vertical spray arms while the traditional setup is only available for single set. Its not just a change on quantity but the control logic is completely different which requires more technical programming setup.
Q: What’s the machine capacity?
A: Basically it’s twice of a traditional 6 axis painting machine and more flexible to work with.
Q: How can I use the machine properly?
A: We have user manual for each machine and we’ll offer training service before delivery. If necessary, we can also send technician to customer factory to teach operators until they can operate our machine properly.
Q: Do I get after sale support?
A: Sure, all our machines are life time supported.
