Jiumu Luxury Custom Wood Finishing – Custom Mixed Oil & Water-Based Paint Solutions


This factory has newly launched a specialized custom paint manufacturing plant with a current workforce of 40 employees.

Production equipment layout: one UV primer spraying line, one water-based topcoat spraying line and one automatic spraying robot.Supporting facilities include standardized sanding booths, professional spray booths and air-energy drying rooms.


Products: Furniture, cabinet panels

Process: UV primer, water-based topcoat, robotic spraying


1. Production Line Configuration & Equipment Selection

Production Line Layout Optimization: The customer equipped a reciprocating UV primer spraying line and water-based topcoat line. Restricted by factory space and energy consumption, the topcoat drying oven was eliminated. Instead, a flash-off booth combined with a forced drying oven was adopted to resolve drying requirements.


Equipment Functional Division: Reciprocating sprayers undertake main surface spraying tasks. Robotic sprayers handle small-batch custom orders, high-end products, and components with low backside finishing requirements. A manual spraying station is also configured for touch-up painting and black line outlining.


Dust Removal System Upgrade: It is recommended that customers avoid double-sided dust cleaning, which tends to cause contamination on workpiece back surfaces. Custom protective spraying paired with manual spraying stations is advised to accommodate complex-shaped workpieces.


2. Workshop Environment & On-site Management

Dust-free Control: Sanding rooms adopt central dust extraction with scraper-type dust removal to maintain a dust-free working environment. UV spraying rooms feature fully enclosed structures with dedicated viewing passages reserved to minimize dust interference.


Space Utilization Optimization: For robotic spraying installation, rigid space requirements are specified: a width reservation of 7–8 meters and a depth reservation of 10 meters (including a 2-meter-wide passage). Cases utilizing side access doors to alleviate space shortages are shared for reference.


Detail Design Solutions: Practical on-site management tips are provided, including fitting red sponge anti-collision pads on temporary drying racks and adopting double-door layouts for easy trolley access and transit.

Core Advantages of Equipment Upgrade


Greatly Improved Production Efficiency

Continuous automatic operation eliminates repeated manual spraying. The daily processing capacity of a single production line rises by over 60%, greatly shortening the delivery cycle of wood door finishing.


Stable & Consistent Finishing Quality

The intelligent robot follows precise pre-set spraying paths, delivering uniform paint film thickness and eliminating common defects such as uneven coating, sagging and missing spray areas caused by manual operation.


Sharp Reduction in Scratches & Surface Damages

Workpieces are easily scratched or bumped during manual handling and handheld spraying. The fully enclosed automatic conveying system avoids direct physical contact with panels, drastically cutting reject rates from surface abrasion.


Lower Paint Consumption & Better Cost Control

The enclosed spray booth with paint recovery system cuts paint waste by 35%. Matched with air-energy drying rooms, overall energy consumption is also reduced.


Standard Dust-Free Production EnvironmentEquipped with PURETE standardized sanding booths, sealed spray booths and constant-temperature drying rooms, perfectly catering to high-end customized mixed oil & water-based paint finishing 


FAQ

Q1:What industries are spray painting machines suitable for?
A1:Spray painting machines are widely used in furniture panels, doors, cabinets, wood moldings, metal parts, plastic components, glass, and decorative materials industries. They are ideal for large-scale continuous production.
Q2:What types of coatings can be used with a spray painting machine?

A2:Spray painting machines can work with various coating systems, including:

UV coatings,Water-based paint,PU paint,NC paint,Primer / Topcoat / Color paint,The configuration depends on the spray gun model and paint supply syste

Q3:What are the advantages of a spray painting machine compared to manual spraying?
A3:Automatic spray painting machines offer:More uniform coating,Higher paint utilization rate,Stable and consistent quality,24-hour continuous operation capability,Reduced labor costs.They are especially suitable for standardized, mass production.
Q4:How does the spray painting machine ensure coating uniformity?
A4:Uniform coating is achieved by precisely controlling the spray gun angle, spray overlap ratio, conveyor speed, and air pressure parameters.Some advanced models are equipped with automatic adjustment systems.
Q5:Is color changing convenient?

A5:Standard models require manual cleaning of pipelines and spray guns.

Machines equipped with automatic cleaning systems can significantly reduce color change time and improve efficiency.

Q6:Is maintenance complicated?
A6:Maintenance mainly includes:Regular spray gun cleaning,Inspection of the air system,Cleaning of filter systems,Proper maintenance extends the machine’s service life.
Q7:Can the spray painting machine be customized?
A7:Yes, it can be customized according to production needs, including:Number of spray guns,Working width,Reciprocating or robotic structure,Integration with automatic flipping or drying systems,Different processes require different configurations.
Q8:Can the spray painting machine be integrated into an automatic production line?
A8:Yes.It can be connected with conveyor systems, drying lines, UV curing equipment, and other machinery to achieve fully automatic continuous spraying production.
