Complete Powder Coating Lines Engineered, Manufactured & Installed by Ketu
From pretreatment to curing oven, Ketu designs and manufactures complete powder coating lines that arrive as one integrated system – ready to install, start and run in your factory.
What Does a Complete Powder Coating Line Factory Mean?
A complete powder coating line factory is more than a machine vendor. It is an engineering and manufacturing partner that designs the whole coating system, builds each key module, tests the line and supports installation on site. At Ketu, we deliver a complete system – not just separate machines.
- Full process design: pretreatment, drying, powder booth, curing oven and conveyor system work as one line.
- All main equipment manufactured in our own factory, referenced to 5 in-house coating lines.
- Pre-assembly and functional testing of core modules before shipment.
- On-site installation support, commissioning and operator training for your local team.

Layout Concept
Complete Powder Coating Line Configurations
Ketu designs different automation levels and layouts according to your budget, product size, output and labor conditions – from manual batch systems to fully automatic continuous lines.
Four Typical Line Concepts
- Manual powder coating lines – low investment, flexible color change, ideal for small batches and many models.
- Semi-automatic lines – overhead conveyor + manual / automatic guns for factories upgrading step by step.
- Fully automatic continuous lines – high-volume, stable products, recipe control and minimum labor per part.
- Special lines for aluminum profiles and long parts – focus on Faraday cage areas and uniform film thickness.
Manual Lines
For job shops, start-ups and factories with many small orders and frequent color changes.
- Manual booth with powder recovery
- Batch or short conveyor + compact oven
Semi-Automatic Lines
For factories moving from manual coating to continuous production with stable takt time.
- Continuous overhead conveyor
- Manual + optional automatic guns
- Basic spray pretreatment & curing oven
Fully Automatic Lines
For core factories where coating is a key process and long-term, high-volume production is required.
- Multi-stage spray pretreatment tunnel
- Automatic guns, recipes & line control
- Gas or electric tunnel curing ovens
Profile & Long-Part Lines
Specially engineered for aluminum profiles, long frames and construction elements.
- Profile racks & long-part conveyors
- Faraday cage control for complex shapes
- Stable, export-level surface quality
From Raw Parts to Finished Products: The Complete Process
Every Ketu line follows a clear and stable process flow, matched to your product, takt time and coating quality level.
Loading & Hanging
Parts are loaded onto the conveyor or manual racks according to weight, size and coating coverage.
Chemical Pretreatment
Multi-stage spray or dip pretreatment (degreasing, rinsing, conversion) for adhesion and corrosion resistance.
Drying Oven
Drying ovens remove water from the surface and stabilize the substrate before powder application.
Powder Application
Manual or automatic guns apply powder with high transfer efficiency in a controlled powder booth.
Curing Oven
Gas or electric curing ovens melt and crosslink the powder coating to form a durable finish layer.
Cooling & Unloading
Parts cool down to safe handling temperature, then operators unload them for inspection and packing.
Inspection & Packaging
Visual QC, thickness checks, adhesion tests and final packaging complete the process and protect the parts.
Why Work with Ketu as Your Complete Line Factory?
We do not simply ship separate machines. We engineer and deliver a complete, balanced powder coating system that runs as one stable production line in your factory.
Ketu engineering team reviewing layouts, oven design and conveyor speed to match your takt time.
System-Level Engineering
We design the line as a complete system – conveyor speed, oven length, booth position and pretreatment stages are matched to each other and to your real output demand.
Proven on Our Own Lines
We operate 5 in-house powder coating lines for our own production and for testing new layouts, energy-saving solutions and application ideas before delivering to customers.
Custom Layouts for Your Workshop
We design each line based on your factory drawing, building height, crane positions and available utilities, not from a generic catalogue drawing.
Energy Saving & Safety
Curing ovens, burners, insulation and air systems are designed to reduce gas and electricity consumption while meeting your local safety and environmental standards.
Turnkey Project Management
One team follows your project from first discussion to final commissioning. You do not need to coordinate multiple suppliers for each part of the line.
Global Export Experience
We understand container loading, overseas shipping, local assembly, and how to integrate with your local powder suppliers and service teams.
Core Equipment We Manufacture in Our Factory
As a complete powder coating line factory, Ketu manufactures and integrates all key equipment into one balanced system – not a mix of unrelated machines.
Pretreatment Systems
- Multi-stage spray tunnels (3–7 stages) for steel and aluminum.
- Dip tanks and manual pretreatment stations for smaller lines.
- Drying ovens to remove water and stabilize the surface.
Powder Application Systems
- Manual powder booths with efficient powder recovery.
- Automatic booths with reciprocators and multiple powder guns.
- Fast color change systems for factories with many colors.
Curing Solutions

FAQ: Building a Complete Powder Coating Line with Ketu
Answers to common questions from factory owners and engineers who are planning a new coating line or upgrading an existing plant.
What information do you need to design a complete line?
We need product photos and dimensions, weight, daily / monthly output targets, current coating process, available workshop size and utilities such as gas, power, water and compressed air.
What is the typical price range of a complete line?
Manual lines are at the lower range and fully automatic multi-stage systems are higher. We always design within an agreed budget range and explain where investment brings real value.
How long is the manufacturing and delivery time?
Typical production time is 60–90 days after deposit and technical confirmation, plus international shipping time to your country and on-site installation period.
Can you help with installation and training?
Yes. We can send engineers to your site to guide installation and commissioning, and we provide full operation and maintenance training for your team.
Can your line work with local powder suppliers?
Yes. Our lines are compatible with major powder brands worldwide. We can share experience with powder selection and process windows based on your application and testing.
How do you ensure safety and stability?
We use proven components, design safety interlocks, emergency stops and ventilation, and test key functions on our own lines before shipment to reduce risks after installation.
What after-sales support do you provide?
We offer online support, spare parts, troubleshooting, and can visit your plant for major upgrades or modifications when needed.
Can you upgrade an existing coating line?
In many cases, yes. We can evaluate your current line and propose partial upgrades – for example new ovens, booths, conveyors or controls – instead of a full replacement.
