Automated mini plant for Bomans Lackering AB
Bomans Lackering AB, one of Scandinavia's most renowned coating companies, has long been recognized for its ability to meet demanding customer specifications in industries such as electronics, telecommunications, and defense systems. As a forward-thinking company, Bomans has always been keen to explore new technologies and has had the ambition to automate part of its coating process for over a decade. The timing was now right to realize that vision.
​
Eksar AB was entrusted to deliver a compact, high-tech automated coating system that includes an ABB paint robot. This project marks a significant step forward for Bomans in their journey towards greater efficiency and sustainability.
Technical information
The new automated paint facility consists of the following key components:
-
ABB IRB 52 Coating Robot: A compact, high-precision coating robot optimized for handling complex and demanding coating tasks on smaller rotationally symmetric components. The robot is equipped with IPS (integrated Process Control) for controlling spray parameters.
-
Spray Booth from Greiff Industimiljö AB: A closed spray booth that creates a safe and controlled working enviroment, equipped with an air recirculation system to save energy and ensure a sustainable coating solution.
-
Conveyor from Hjort Conveyor AB: A floor-mounted conveyor (Series 4500) that transports components through the facility. In front of the robot the products can be rotated with an adjustable speed of 60-120 RPM to ensure even and precise application.
​
-
Paint distribution and application equipment from syntema in Arbrå AB (Graco): Two low-pressure spray guns (AirPro-Auto) fed by separate pressure tanks. Paint volume is regulated via a pressure controller. Paint, Shape air and Atomizing air are all controlled directly through the robot's IPS for optimal paint applcation.
Workflow
1. Components are placed on the conveyor, which transports them to the ABB coating robot. The parts are rotated at a controlled speed in front of the robot.
2. The robot's pre- programmed movements apply paint with high precision across the entire surface of the components as they rotate.
3. Once fully coated, the parts are transported out of the spray booth and to the unloading area.
"We´ve considered automation for many years but had some hurdles to overcome, both with the investment and the technology. Thanks to Eksar and their approach, the transition from manual to automated processes was much easier than we expected."
Says Peter Älander, Bomans Lackering AB
Bomans has always been open to new technology and investing in an automated coating solution was a natural step to meet increasing customer demands. Robot automation has resulted in higher production speeds, improved quality and reduced paint consumption, while also creating a safer and more sustainable work enviroment.
The new painting facility is expected to provide a significant return on investment through increased capacity, enhanced production speed, and greater precision, while also substantially improving the working environment.
