Automatic Powder Coating Lines For High-Volume, Stable & Repeatable Production
Ketu designs and builds automatic powder coating lines for factories that need stable output, consistent film thickness, and reliable colour quality. From pretreatment to curing oven and conveyor, every section is engineered to run as one system—not as separate machines.
- Stable takt time & balanced production flow
- Consistent film thickness on complex parts
- Lower labour cost with automatic guns & conveyors
- Flexible layout for new plants or upgrades
24/7 Stable Operation
Designed for continuous production
Average Customer Output Increase
+30–40%
Is an Automatic Powder Coating Line Right for Your Factory?
An automatic powder coating line is ideal for factories that already have stable orders and need more output per shift. Instead of relying on manual operators to control coating quality, the line uses automatic guns, reciprocators, and a conveyor to keep every part within a defined process window.
This page is for you if:
- Your current manual line cannot keep up with order volume.
- You need stable film thickness for OEM or export customers.
- You want to reduce dependence on skilled operators.
- You are planning a new plant and want to start directly with automatic coating.

Automatic Line Overview
Example layout: pretreatment → drying oven → automatic booth → curing oven → cooling & unloading. We adapt the design to your parts, building and throughput.
What Exactly Is an Automatic Powder Coating Line?
An automatic powder coating line combines continuous or step-by-step conveyor movement with automatic spray guns and a PLC control system. Parts travel through pretreatment, drying, powder booth, curing oven and cooling section according to a defined recipe.
Key components:
- • Pretreatment section: spray tunnel or immersion cleaning & conversion coating.
- • Drying oven: removes moisture before coating.
- • Automatic powder coating booth: with gun movers and powder feed centre.
- • Curing oven: gas / diesel / electric, with temperature and time control.
- • Conveyor system: overhead or floor conveyor linking all sections.
- • Control system: PLC + HMI for line speed, guns, ovens and safety interlocks.
The result is a stable, repeatable coating process that can be documented, audited and scaled with your business.
Typical Ketu Automatic Line Configuration
Every factory is different, but most Ketu automatic lines follow this basic structure. We adjust each section to match your parts, required performance and workshop.
- Loading area
- Pretreatment tunnel (degreasing, rinsing, conversion, DI rinsing)
- Drip-off zone
- Drying oven
- Cooling section
- Automatic powder coating booth
- Touch-up station (optional manual booth)
- Curing oven (gas / diesel / electric)
- Cooling & inspection area
- Unloading & packing area
Line speed
Typically 1.0–4.0 m/min depending on part size & curing time.
Conveyor type
Overhead power & free or closed-track conveyor for balanced flow.
Part size & weight
Defined per project to match your largest and heaviest parts.
Hanging design
Single or double row hanging for different product types.

Automation & Control: Stable Output, Less Operator Stress
Ketu automatic lines use a centralized control system so each section works in sync. Instead of operators guessing line speed and gun settings, you define recipes for each product family.
PLC & HMI
Line speed, oven temperature and safety interlocks managed from one interface.
Gun Control
Adjust kV, µA and powder output per zone according to your part geometry.
Recipes
Save and recall settings for each product family to reduce variation.
Sensors & Alarms
Part detection and alarm system to protect both equipment and operators.
With clear data and standardised settings, training new operators becomes easier and daily operation more predictable.
Use real photos of your PLC cabinet, HMI screens and operator interface to build trust with engineering teams.
High-Performance Powder Application for Consistent Coverage
The heart of an automatic line is the powder application section. Ketu designs the booth, gun arrangement and reciprocator travel according to your specific parts and colours.
Automatic Guns & Reciprocators
Guns from trusted brands combined with vertical or multi-axis movement to follow your part geometry.
- • Optimised gun positioning per part family
- • Adjustable stroke and speed for different sizes
- • Easy access for cleaning and maintenance
Powder Feed Centre & Reclaim
Stable powder delivery, sieving and recovery keep your consumption under control and the system running clean.
- • Powder feed centre with level monitoring
- • Cyclone + filter or cartridge filter design
- • Quick colour change options for multi-colour plants
Coating Result on Real Parts
Use before/after photos and close-ups of coated parts to show coverage on corners, recesses and complex geometries.
- • Stable film thickness across surfaces
- • Reduced orange peel and defects
- • Repeatable colour and gloss level
Real Projects: From Manual Bottlenecks to Stable Automatic Lines
A few examples of how factories in different countries and industries upgraded to Ketu automatic powder coating lines.
Cabinet Manufacturer
North Africa
The customer produced electrical cabinets manually with unstable film thickness and low output. After upgrading to a Ketu automatic line, they achieved:
- • +40% output per shift
- • More stable coating thickness within OEM tolerance
- • Cleaner workshop and better working conditions
Aluminum Profile Factory
India
The factory needed consistent quality for export markets and struggled with manual coating on long profiles. Ketu designed an automatic line with:
- • Long-length overhead conveyor and profile hanging
- • Process design to reduce Faraday cage issues
- • Optimised gun positioning and reciprocator stroke
Metal Furniture Producer
Turkey or Domestic
Order volume grew quickly, but the manual line became a bottleneck. With a Ketu automatic line using quick colour change design, the factory:
- • Kept frequent colour changes for many SKUs
- • Reduced colour-change time and powder waste
- • Increased capacity for best-selling models
Quality & Safety Built into Every Automatic Line
Automatic powder coating lines operate continuously, so safety and quality control are critical. Ketu designs each project to meet local regulations and your customer’s requirements.
Mechanical Structure
Robust steel structure for booths, ovens and conveyor supports.
Oven Safety
Temperature control, interlocks and airflow design to protect your team.
Air & Filtration
Proper ventilation and filter systems for a clean working environment.
Documentation
Operating manuals, maintenance schedules and training support.
You can later add specific certifications, test methods and standards to this section based on your real projects.
