CASE STUDY
2026High-performance pretreatment and liquid painting system for electromechanical components
Customer
Primabiro (Croatia)
Objective
- Optimize the painting processes for small components used in onboard systems.
- Eliminate ATEX safety risks and improve working conditions for operators exposed to outdoor work.
- Ensure full traceability of parts and reduce downtime caused by materials going missing in the workshop.
Challenges
- Manage the plant layout within a limited space through custom design and subsequent dedicated expansion of the production area.
- Integrate advanced processing, coating, and storage technologies into a single, logical, and controlled workflow.
Impact
The project made it possible to permanently eliminate the organizational challenges that had characterized the handling of large, heavy items, ensuring optimal operational efficiency from the very first stages of processing. The transition to a controlled environment has dramatically raised safety standards and air quality for operators. The added value of the investment lies in the reliability of the process and the scalability of the plant, which places Primabiro in a competitive position to meet the growing demands of the international market.
The implemented solutions are distinguished by:
- Advanced digital control via electrical panels integrated with PLCs, which constantly monitor the cabins’ parameters, safety, and the operation of the entire line.
- Superior logistics organization, with dedicated areas for each stage, from pre-treatment to final drying.
- Strict compliance with safety regulations, ensuring a healthy and safe work environment.
Shot Blasting and Surface Preparation Booth
The initial processing of components takes place inside a high-performance enclosed module, which completely eliminates the need for open-air processing. The cabin body consists of insulated panels with high-density mineral wool insulation on the inside, an engineering design that ensures high soundproofing properties to reduce noise in the surrounding environment. The interior is fully protected by an abrasion-resistant rubber lining and is equipped with a ventilation system that directs dust toward the external filter unit, ensuring optimal visibility for the operator at all times. Each access point is monitored by safety sensors and indicator lights that control access authorization and visually signal the status of the operating cycle.
Abrasive Recovery and Regeneration System
The efficiency of the preparation phase is enhanced by an automated system that manages the entire consumables cycle without interruption. The mixture of abrasive and slag that settles on the floor is collected by a scraper system and conveyed via a bucket elevator to the separator. The system thoroughly separates the grit from contaminating dust and coarse residues, storing the clean abrasive in a silo. The reclaimed material is then returned to the sandblasting machine, ensuring continuous operation and drastically reducing material consumption and waste.
Pressurized paint booths and drying ovens
The finishing process was designed to provide a continuous and streamlined workflow. The various areas, dedicated to liquid painting and drying, have been arranged to maximize operational efficiency and reduce throughput times. The integration of these modules enables orderly and repeatable process management, minimizing the risk of contamination and ensuring a uniform aesthetic and protective finish.
Logistics Management and Buffering
To address the issue of misplaced components previously identified, the facility includes a large area dedicated to storing semi-finished parts suspended from racks. This solution not only facilitates handling but also enables constant visual and digital monitoring of parts inventory. The system ensures that every component is traceable, eliminating time wasted searching for and relocating materials and enabling orderly industrial management of the production flow.
