Lines tailored for furniture, cabinets and aluminum profiles.
Balanced Investment & Capacity
Manual, semi-automatic or fully automatic configurations.
Energy & Quality Focused
Optimized ovens and recipes for consistent coating quality.
Spray Pretreatment
Multi-stage tunnel for cleaning & conversion.
Powder Spray Booth
Automatic & manual guns with recovery system.
Curing Oven

More Than a Booth and an Oven
In Ketu’s definition, a powder coating line is a complete material-flow system. It connects pretreatment, drying, powder coating and curing with conveyor, hangers and operators to form one stable process that runs every day on your factory floor.
-
Designed from your real products, takt time and plant layout – not just catalog drawings.
-
Each module (pretreatment, booth, oven, conveyor) is sized and matched as one system.
-
Energy consumption, manpower and quality are all visible and controllable.
Hanger & Loading Concept
Optimized for weight, shape and nesting.
Conveyor & Flow
Line speed and pitch set by takt time.
Powder Coating Lines for Your Industry
Our powder coating lines are engineered for real factories – metal furniture, electrical cabinets, aluminum profiles and general metal fabrication.
Metal Furniture Factories
Outdoor sets, garden furniture, shelves and frames with high appearance and weathering requirements, often with frequent color changes.
- Quick color change systems
- Multi-color production per shift
- Stable film thickness and gloss
Electrical Cabinets & Enclosures
Switchgear cabinets, telecom enclosures and control panels requiring strong corrosion protection and reliable electrical performance.
- Heavy-duty conveyor for large bodies
- Enhanced pretreatment for corrosion resistance
- Oven design for thick steel panels
Aluminum Profile Producers
Architectural and industrial profiles for doors, windows, curtain walls and exports to demanding markets.
- Solve shielding on edges and corners
- Uniform film thickness on long profiles
- Line concepts for 6–7 m or longer pieces
Choose the Right Line Configuration
From manual to fully automatic powder coating lines, we match the technology level with your output, labor and product mix.
One Concept – Four Configurations
All four line configurations follow the same core logic: stable material flow, matched modules and clear takt time. The difference is automation level, investment and required manpower.
- Manual lines – flexible, low investment, ideal for small batches and many colors.
- Semi-automatic lines – add conveyor and basic automation while keeping flexibility.
- Fully automatic lines – for stable, high-volume series and minimum labor per part.
- Hybrid solutions – combine automatic zones with manual stations for complex parts.
Manual Lines
Ideal for small batches, many colors and flexible product mix in job shops or start-up factories.
- Manual spray booth with recovery
- Batch or short-loop conveyor
- Compact curing oven
Semi-Automatic Lines
For factories upgrading from purely manual coating while keeping investment under control.
- Continuous overhead conveyor
- Manual + automatic guns
- Integrated oven and basic pretreatment
Fully Automatic Lines
For high-volume, stable product series where output, consistency and low labor cost are critical.
- Continuous conveyor or power & free
- Multi-stage spray pretreatment
- Automatic guns and recipe control
- Gas or electric curing oven
Hybrid Solutions
Combine automatic zones for main products with manual stations for complex or low-volume parts.
- Automatic sections for repeat parts
- Manual touch-up / special racks
- Reuse of existing equipment possible

How We Build Your Powder Coating Line
We use a clear step-by-step process to move from first discussion to stable line running in your plant.
- 1. Initial consultation: products, output, layout and utilities.
- 2. Concept & budget: 1–2 layouts with budget range for internal decision.
- 3. Layout optimization: refine flow with your production and engineering teams.
- 4. Detailed design: mechanical, electrical and interface drawings.
- 5. Manufacturing & pre-assembly: modules built and tested at Ketu.
- 6. Installation & commissioning: supervised installation on site.
- 7. Trial production & training: run your real parts and train operators.
- 8. After-sales support: remote and on-site service plus spare parts.
