Passt Coating AG, Nunningen
- Before
- No powder coaters left to hire, orders piling up, the business close to shutting down.
- After
- The old line runs at full capacity again, and the plant is now our demo site in Switzerland.
4 months to full capacity
Robots and painting systems for industry Robots take over the manual work you can no longer staff.
We build painting systems with Lesta robots: painting robots in existing booths and carousel cells, plus inspection cells and special machinery. For job coaters, paint shops and manufacturers, on subscription or to buy.
More than 200 robots at more than 150 customers · Application technology for the paint industry since 2008

What we build
From a robot in your booth to a complete line.
We plan, build, commission and service afterwards. Most projects start in a booth that is already there.
-
Painting robots in existing booths
Powder and wet paint, with your guns and your paint supply. Your painter shows the movement once.
Example: Passt Coating AG, Nunningen -
Cells with carousel and turntable
Four arms, rotary unit, heavy duty up to 400 kg. One part is painted while the next is loaded.
Example: Plastics paint shop for medical technology in the Black Forest-Baar district -
Robots on chain conveyors
An encoder on the chain sprocket tells the robot how fast the parts are moving. The line stays as it is.
Example: Family-run paint shop in the Hegau region -
Linear and lifting axes
Up to 6 meters of travel for truck bodies and long profiles, lifting axes for undercuts on the line.
Example: Krone Group, coating plant in Emsland -
Retrofitting existing lines
New controls, scanners and operation for a line nobody could maintain anymore.
Example: Window manufacturer in the Upper Palatinate -
Inspection and measuring cells
A KUKA robot guides a 3D scanner or a deflectometry sensor over every part and files the result.
Example: Camouflage Automotive, Heilbronn: inspection cell -
Special machinery
An aerospace cell with a pit and an Ex zone, flame treatment and painting on one axis, rotary fixtures of our own design.
Example: BORBET, wheel plant in Thuringia -
2K mixing and dosing
Our own low-pressure dosing with servo motors and gear pumps, dosed by volume instead of pressure.
Example: Family-owned paint shop in Emsland -
Palletizing and handling
Cells for the end of the line. We simulate gripper, cycle time and reach before anything is built.
More: Systems and special machinery -
Application technology since 2008
Spray guns, pumps, spare parts and overhauls for your manual booths and your robots.

When we advise against
Sometimes a robot is the wrong answer.
We say so before the offer, not after the order.
March 2026
A furniture maker wanted a painting robot.
About 500 m² of painted surface a day, 30 own colors, 20 to 30 color changes a day, parts almost four meters long. After the walkthrough we advised against it: the parts are too long for the booths, and the team paints the edges of stacked panels by hand simply and quickly. Most defects came earlier anyway, as dents in foil-coated panels that nobody sees before painting. We proposed a simple inspection station that measures every panel before and after painting.
About quality inspection How a project runs, step by step-
March 2026
An industrial paint shop tested a transport robot for its hall. Glossy parts disturbed the sensors. We did not keep using it there.
-
September 2026
A maker of heavy drive parts asked for a low-cost cobot for the paint booth. We advised against it, because cobots need a lot of maintenance in paint mist and solvents, and proposed an industrial robot on a rail.
-
Every project
The first question is: does it take one robot or a whole system? We ask it in the first conversation.

What plant managers ask before their first robot
-
A painting robot in your existing booth costs from EUR 2,900 a month, including installation, maintenance and spare parts. Cells, inspection cells and special machines are priced after a free site walkthrough. We also tell you when it does not pay off.
-
No. Your painter teaches a painting robot by showing the motion, and with many variants a scanner recognizes the part and picks the program. Inspection cells and special machines are handed over with finished recipes, and we train your team to run them.
-
At an industrial painter in the Upper Palatinate, the first test program ran one week after arrival on site; with pre-assembly in Altstätten it was four weeks to the first painted part. At a plastics painter for medical technology it took one month from the first day on site to handover. Special machines take longer: we give you the schedule after the walkthrough.
-
No. We install during plant holidays or station by station. At a window maker in the Upper Palatinate, the retrofit of an entire painting line stayed on plan on 14 of 14 days.
-
We check remotely first, and a technician comes if needed. After a collision at a contract coater in Emsland, production was running again after about four hours. If a robot on the chain goes into alarm, the chain stops and your team can keep working by hand. What is binding is in your contract.
-
We do, from Altstätten: remote diagnosis first, then a technician on site. Maintenance and safety checks on schedule, one report per visit. At the contract coater in Emsland, for example, we replace the control cabinet coolers during regular service, about one hour per robot.
-
The robot does the repetitions, your people make the decisions. At an agricultural machinery maker the coater stays at the booth, at Sievers Lackierungen the team gave the robot a name, and at a paint shop in Saarland the painter now improves the programs himself. We train on site until your team runs the system on its own.
