Robotic paint systems
Paint to order.
Change colour automatically.
Mexx designs and builds robotic paint lines, from complete multi-booth finishing plants to compact coating cells. Each product is painted in the colour its order needs as it comes down the line, so you stop painting for stock.

Case study: Ashton Manufacturing
From painting for stock to painting on demand
Ashton used to paint products ahead of time and store them, which took up a lot of floor space. Mexx built a robotic finishing line that paints each product when it is needed.
- Products arrive on a conveyor and are measured on the way in
- Each one is painted in the colour its order calls for
- The system changes colour automatically for the next product
- Stock is held unpainted, freeing up the space finished stock used to take
How it works
Load, paint, cure, unload
Products move through two paint booths and into curing in a controlled sequence, with operators only at each end of the line.
01
Load and measure
Products are loaded and indexed in. Width, height and length are checked on the way in.
02
First coat
A robot applies the first coat in a temperature-controlled booth.
03
Tack-off
Products rest for about 10 minutes between coats.
04
Second coat
A second robotic booth applies the next coat.
05
Cure and unload
About 30 minutes of curing, then cooling conveyors. An alarm warns the operator before a part reaches the end.
What’s inside
Everything the paint process needs
ABB paint robots
Purpose-built painting robots with automatic spray guns and protective covers.
Automatic colour change
Colour changers on the robots, a paint kitchen of up to 26 colours, automatic 2K mixing of resin and catalyst, and automatic gun and line cleaning.
Controlled booths
Custom spray booths with dry filtration and temperature control, so the finish stays consistent all year.
Conveying and controls
Indexing, transfer, curing and cooling conveyors, all run from one operator screen.
Robotic coating cells
Smaller parts and shorter runs
Not every job needs a full paint line. For smaller parts and shorter runs, a compact robotic coating cell gives the same repeatable finish in far less floor space. We can supply the spray enclosure, or set the robot up in your existing booth.
Choosing the right robot matters. Paints and solvents that create a flammable atmosphere need a hazardous-area rated paint robot. Cobots aren’t explosion-protected, so our MexxBot Coat cobot system is for water-based paints, polyurea linings and other coatings that aren’t flammable. We’ll tell you which one your coating needs.

Service & support
Supported by the people who built it
Mexx engineers design, build and commission every system, then stay on to support it. We run service contracts on bagging and de-bagging lines, log in remotely to find faults fast, and provide after-hours on-call support for machines across Australia and New Zealand. We also service automation built by others.
