What’s happening at Proton Finishing in Eskilstuna

Heat recycling

By installing a heat exchanger, the plant can use the heat from the drying oven and the curing oven for the pre-treatment. Energy that previously went to waste and was simply vented out. This reduces the plant’s LPG consumption by about 8 per cent, which significantly lowers its carbon footprint.

Powder coating booth

Previously, many steps had to be done manually. The staff worked with exoskeletons and masks to reduce the risk of injury, but the physical working environment was still demanding. The new powder coating booth is a closed system with significantly fewer manual steps, which will improve the working environment. It also reduces the amount of powder consumed and streamlines production.


The efficient new blaster, installed in 2023, is a replacement investment that will allow for energy recycling and an improved working environment. Old blasters often have many moving parts and leak substances, leading to risks of crush injuries and slippery floors. The new blaster will have a closed system, preventing both of these risks.

Sustainability Developers Sandra Vatn and Site Manager Marcus Anderberg inspect the powder coating booth, which is now ready to go online.
