Surface Preparation, Shot Blasting, Cleaning and Pre-Treatment, E-Coating

To maximize the lifespan and reliability of heavy vehicles, effective corrosion protection of key components is essential. CTI Systems designs paint systems that offer exceptional flexibility, seamlessly integrating with a facility’s manufacturing, storage, and handling functions to optimize the entire coating process.

For large, heavy steel components—often welded and prone to corrosion—preparation typically includes shot-blasting, cleaning, and pre-treatment before E-coating, powder coating, or wet painting. CTI’s paint systems bring all these crucial process steps into one fully integrated plant, utilizing advanced automated intralogistics technology to ensure each step in the corrosion protection process is smoothly connected.

Proper surface preparation is essential for achieving corrosion-resistant, consistently clean finishes. For large welded structures, the process begins with shot-blasting, which effectively removes rust and creates a slightly roughened surface, improving paint adhesion during the coating phase.

After shot-blasting, it is essential to remove any residual shot material. CTI’s dedicated de-sanding device safely rotates and tilts each part to ensure all excess shot is cleared, leaving a pristine surface ready for the next stage.

CTI’s extensive range of spray washing systems and immersion baths ensures even the largest and most complex parts are thoroughly and efficiently cleaned. With a key focus on environmental responsibility, each CTI installation includes water and waste treatment systems, demineralization, and filtration solutions. Our portfolio also includes zinc phosphating lines and thin-film technology to support various pre-treatment needs.

Electro-coating or e-coating, is one of the most effective and eco-friendly painting technologies as of today, providing superior corrosion resistance. CTI’s advanced digital solutions support precise application control, enabling consistent, high-quality finishes with exceptional durability. E-coating, alongside powder coating, offers reliable, environmentally sustainable protection for every component.
