In the agricultural machinery industry, mechanical performance is no longer the sole decisive factor. Today, aesthetic quality, customized finishes, and efficient production processes play a key role in a company’s competitiveness. In this context, Verona Impianti designed, manufactured, and installed a new powder coating line for coating agricultural discs at O.F.A.S. S.p.A., an Italian leader in the production of agricultural components.

The client: O.F.A.S. S.p.A., a specialist in agricultural machinery discs

O.F.A.S. S.p.A., headquartered in Mussolente (Vicenza), is a long-established industrial company with over 70 years of experience in the design and manufacture of discs for seed drills and harrows, as well as a wide range of other steel and rubber components for the agricultural sector. The company operates on an international scale and is recognized for the high quality of its materials, its technological innovation, and its ability to anticipate market demands.

In recent years, the evolution of agricultural machinery toward standards increasingly aligned with the automotive industry has led O.F.A.S. to rethink surface finishing, transforming it into a true distinguishing feature of its products.

The challenge: reducing consumption while increasing flexibility and productivity in the coating department

OFAS already had a powder coating system, but the existing setup faced several critical issues:

  • High energy consumption due to an outdated, poorly insulated oven with insufficient internal ventilation
  • Long start-up times and low thermal efficiency
  • Limited flexibility and productivity of the coating line
  • The need to run three continuous shifts, resulting in high operating costs

The objective was clear: to implement a new powder coating plant capable of delivering energy efficiency, high operational performance, and consistent quality, without interrupting production.

The solution: a tailor-made coating plant designed by Verona Impianti

To meet this challenge, O.F.A.S. turned to Verona Impianti, selecting a partner capable of designing a fully customized coating line, seamlessly integrated into the existing production facility.

The solution developed by Verona Impianti includes:

  • Custom overhead conveyor, engineered to handle the heavy loads processed by O.F.A.S., with adjustable speed according to production requirements and a 90-meter path through the oven.
  • High-efficiency curing oven, featuring:
    • 150 mm rock wool insulation
    • Elimination of thermal bridges between hot internal and cold external components
    • Dual burners with a total output of 800 kW
    • Rapid start-up (just 30 minutes compared to 3 hours with the previous oven)

Every component of the system has been designed to ensure uniform temperature, high-quality finishes, and minimized energy losses.

Customer benefits: lower energy consumption, higher productivity, and superior quality

Just a few months after the new coating plant went into operation, the benefits for OFAS are already tangible and measurable:

  • Energy consumption reduced by up to 50%, for both natural gas and electricity
  • Transition from three production shifts to a single shift, significantly enhancing operational efficiency
  • Higher-quality powder coating, with uniform curing and superior aesthetic finishes
  • Improved working conditions for operators, thanks to better oven insulation and more stable temperature control
  • Recovery of approximately 100 m2 of production space, due to a more compact layout compared to the previous line

An additional highlight was the project execution: Verona Impianti dismantled the old system and installed the new plant during the summer break, ensuring uninterrupted production.

Verona Impianti: high-efficiency industrial painting solutions

This project confirms Verona Impianti's approach: not simply providing standard systems, but customized industrial coating solutions, designed to improve energy efficiency, product quality, and customer competitiveness.

From initial analysis to commissioning, each phase is guided by a specific goal: transforming coating into a strategic advantage, not just a process cost.
