Cleanliness test

The cleanliness test is an analytical procedure that allows us to quantify and qualify residual contamination on metal surfaces after decontamination processes. This step is essential to validate cleaning effectiveness and to prevent issues that could compromise the functionality, reliability, or durability of components.
Analyses follow international protocols (e.g., ISO 16232, VDA 19) and enable detection of:
Particulate: solid particles of various nature (metal, plastic, fibers, etc.), analyzed by count, size, and mass.

  • Filmic residues: thin traces of oils, greases, or process fluids.
  • Ionic contaminants: chlorides, sulfates, nitrates—potentially corrosive.
  • Organic contaminants: solvents, adhesives, carbon-based compounds.

Advanced techniques such as scanning electron microscopy (SEM) and EDS spectroscopy allow precise identification of the structure and composition of contaminants. The key unit of measure is the micrometer (µm), the reference parameter for particle size classification.

Surface Tension Test

The surface tension test is essential for evaluating a metal surface’s energy, a parameter that directly affects adhesion, wettability, weldability, and corrosion resistance.
Using calibrated test inks (typically between 36 and 40 mN/m), we assess material response to determine behavior with technical liquids (paints, adhesives, solders). The contact angle (θ) between liquid and surface provides insight into cleanliness and the substrate’s physicochemical properties.

  • Assess wettability to improve coating adhesion
  • Surface quality control after decontamination
  • Optimization of welding processes
  • Study of corrosion behavior
Feasibility study

The feasibility study is the starting point for every structured project. It is not only about verifying whether it can be done, but understanding how to do it best. Through a multidimensional analysis, we evaluate the real possibility of implementing the customer’s request effectively, sustainably, and in line with objectives.

  • Technical–operational assessment: compatibility between the project and company resources—plants, lab instrumentation, technical skills—and the possibility of adopting new technologies.
  • Organizational analysis: definition of roles, timelines, responsibilities, and operational flows needed for effective project management.
  • Risk analysis: identification and proactive management of potential risks—technical, economic, or managerial—that could affect project success.
  • Provide an objective, structured assessment of project viability
  • Identify critical points and success levers
  • Offer strategic and operational recommendations for optimal execution
