Our History

Since the 1980s, Prometals has combined metallurgy, fluid dynamics, and process engineering to solve complex refining challenges. From early development in Brazil to international deliveries, our trajectory is defined by continuous improvement.

  • 1980s: Foundation and first refiner disc programs.
  • 1990s: Expansion into pulp & paper and starch extraction lines.
  • 2000s: Introduction of customized blade geometries and heat treatments.
  • 2010s: International partnerships and technical assistance abroad.
  • Today: Full portfolio spanning low- and high-consistency refining, diagnostics, and reengineering services.

Our engineering workflow integrates CFD-inspired flow reasoning, blade geometry optimization, and metallurgy selection to tune cutting intensity, residence time, and wear behavior. Laboratory analyses—chemical composition, hardness, microstructure—and on-machine trials validate every design iteration.

  • In-house test protocols for LC and HC refining.
  • Rapid prototyping for pattern trials.
  • Field diagnostics and data logging for energy and quality KPIs.

Quality at Prometals is embedded in every step—from billet selection and heat treatment to final inspection. We maintain traceability and process controls aligned with market expectations for industrial equipment.

  • Dimensional and flatness checks on 100% of discs.
  • Hardness profiles across the refining area.
  • Dynamic balance and surface integrity verification.
  • Documentation delivered on request.

We work within a practical ecosystem—customers, universities, foundries, and technology partners—to shorten learning cycles and scale proven solutions. Our related site, Techmelt, extends materials know-how for specialized applications.

  • Joint testing and pilot trials.
  • Knowledge sharing through workshops and webinars.
  • Supplier development for consistent inputs.
