Advertising Sign Coating Challenges Solved by KETU Technology
Advertising product manufacturers need large-size compatibility, attractive appearance, weather resistance, flexible production, and stable curing. KETU designs the line around oversized parts and durable display equipment coating.
Oversized Advertising Frames Are Difficult to Coat
Challenge: Billboard frames and display structures can be very large. Standard small booths and ovens may not provide enough passing size, operator space, or airflow stability. KETU Solution: The reference line supports maximum passing size of 8 × 2.5 × 3 m. A walk-in manual powder spraying room gives operators enough space for large advertising frames and display structures.- Large workpiece compatibility for billboard and display equipment coating.
- Walk-in booth provides flexible spraying access.
- Hanging method can be customized according to frame size and weight.
Outdoor Durability and Corrosion Resistance
Challenge: Outdoor billboards, signboards, and advertising frames face rain, sunlight, dust, wind, temperature changes, and long-term exposure. KETU Solution: Manual polishing pretreatment, correct powder selection, controlled coating thickness, and stable natural gas curing help improve coating adhesion and outdoor durability.- Surface preparation improves adhesion before coating.
- Natural gas curing supports stable film formation.
- Suitable for outdoor advertising sign coating and display equipment coating.
Visible Surface Quality and Brand Color Consistency
Challenge: Advertising signs and display racks are visual products. Poor gloss, uneven color, orange peel, dust points, and coating defects reduce perceived product quality. KETU Solution: Controlled powder application, suitable booth airflow, polishing pretreatment, and variable temperature curing help improve coating appearance and color stability.- Better visible surface finish for signage manufacturing.
- Flexible colors for brand-specific advertising projects.
- Reduced rework through stable spraying and curing process.
Custom Orders and Mixed Product Sizes
Challenge: Advertising factories often produce different signs, frames, displays, and project-specific structures. A fixed automatic line may lack flexibility. KETU Solution: Walk-in manual powder spraying room, customized conveying, and flexible curing design help factories process mixed advertising products and custom-size display structures.- Suitable for project-based signage manufacturing.
- Manual spraying improves control for irregular advertising frames.
- Custom line layout supports large and small display equipment.

This reference electrostatic coating equipment was designed and built for a billboard company positioned in the middle and high-end market. The coating products are mainly advertising frames, with monthly spraying volume around 50,000 pieces.Advertising Frame Powder Coating Production Line
The maximum size of the production line is 8 meters long × 2.5 meters wide × 3 meters high. The process includes workpiece grinding pretreatment, hanging workpiece, powder coating, entering curing furnace, curing completed, cooling, and removing workpiece.
Main Systems in Advertising Product Coating Equipment
The advertising electrostatic powder coating line uses static electricity to evenly attract powder and form a uniform coating on the workpiece surface.
01 Pretreatment System
Manual polishing and surface preparation remove defects, rust, oil marks, and welding residues before advertising sign coating.
02 Electrostatic Spray Gun
The powder is charged by a high-voltage static generator and sprayed onto grounded workpieces using a spray gun.
03 Walk-In Spray Room
The walk-in manual powder spraying room provides enough operating space for large advertising frames and display structures.
04 Conveying System
Hanging, moving, and passing systems are designed according to the large size and weight of billboard frames and sign structures.
05 Curing Furnace
Natural gas curing oven melts and solidifies powder to form a durable and attractive coating layer for advertising products.
06 Environmental and Safety System
Powder collection, airflow control, dust treatment, operator protection, and safe heating design support cleaner and safer production.Complete Advertising Frame Powder Coating Process
The reference process follows: workpiece grinding pretreatment, hanging workpiece, powder coating, curing furnace, curing completed, cooling, and removing workpiece.Stage 1: Workpiece Grinding Pretreatment
Advertising frames are manually polished or ground to remove surface defects, welding marks, rust, oil stains, and sharp burrs before coating.Stage 2: Hanging Workpiece
Large billboard frames and sign structures are hung with suitable fixtures. Correct hanging improves operator access, grounding, and coating coverage.Stage 3: Powder Coating
The workpiece enters the walk-in manual powder spraying room. Charged powder adheres to the grounded surface and forms an even coating layer.Stage 4: Entering Curing Furnace
After spraying, the workpiece leaves the powder coating room and enters the natural gas curing furnace for high-temperature baking.Stage 5: Curing Completed
Powder coating melts, levels, and solidifies into a durable film with good adhesion, appearance, and outdoor protection.Stage 6: Cooling and Removing Workpiece
The finished workpiece is cooled, removed, inspected, and prepared for assembly, shipment, or final advertising product installation.Why Electrostatic Powder Coating Fits Advertising Products

How to Choose an Advertising Industry Powder Coating Line
When purchasing a powder coating line for advertising products, evaluate maximum workpiece size, product type, surface quality, outdoor durability, spray room structure, curing capacity, line flexibility, and long-term cost-effectiveness.
Confirm Maximum Passing Size
Advertising frames can be very large. Confirm the largest length, width, height, weight, and turning space before selecting booth and oven dimensions.Define Outdoor Performance Requirements
Outdoor signs need coating resistance to rain, UV exposure, temperature changes, dust, and corrosion. Powder type and pretreatment should match the use environment.
Select the Right Spray Room
Walk-in manual powder spraying room is practical for oversized and project-based advertising frames. Automatic spraying can be considered for repeated small display parts.
Plan Pretreatment Carefully
Manual polishing and rust removal improve coating adhesion and appearance. For outdoor signs, surface preparation is critical to long-term durability.
Check Curing Oven Capacity
Large metal frames need enough heat absorption time. Natural gas curing, fan capacity, oven size, and variable temperature control should be matched to workpiece size.
Evaluate Color and Finish Flexibility
Advertising projects often require brand colors, custom finishes, and short batches. The coating line should allow practical color and powder changes.
Review Safety and Environment
Check powder collection, booth airflow, oven exhaust, gas safety, operator protection, fire safety, and local environmental compliance.
Calculate Total Cost
Compare equipment cost with powder consumption, energy cost, labor, rework rate, maintenance, and finished advertising product value.
Confirm Service and Installation Support
Large equipment requires careful installation. Confirm supplier support for layout design, commissioning, training, spare parts, and after-sales service.
Plan Future Scalability
If you may expand to more display products or higher output later, reserve workshop space and layout options for future upgrades.
