Standard cleaning is a surface decontamination process that combines chemical detergents with physical means (e.g., ultrasonics, agitation, spraying, or immersion) to selectively remove heterogeneous contaminants from metallic surfaces.
These contaminants may include oils, greases, metallic particles, chips, dust, and residues from mechanical or chemical processing.
The effectiveness of the treatment depends on the type of contaminant, the substrate material, and the technology used (ultrasonics, high-pressure washing, solvents, or aqueous solutions).
Standard cleaning is a critical preparatory step to ensure compatibility and effectiveness of subsequent processes such as electroplating, painting, welding, or structural bonding.
- Effective removal of organic and inorganic surface contaminants (oils, dust, chips).
- Improved wettability and adhesion properties of the substrate.
- Prevention of functional or visual defects in subsequent treatments.
- Optimal preparation for surface conversion processes (anodizing, passivation, painting).
Technical cleaning is an advanced industrial cleaning process designed to remove sub-micrometric contaminants from metallic and non-metallic surfaces using high-precision technologies.
It combines physical methods (e.g., ultrasonics, controlled spraying, vacuum) with specific chemical solutions to eliminate residues such as fine particulate (PM₁₀, PM₂.₅), fibers, ionic salts, abrasives, and invisible thin-film contaminants.
This treatment is essential in high-sensitivity fields (e.g., automotive, aerospace, electronics, optics), where even minimal contamination may compromise reliability.
Quality is ensured through certified cleanliness tests and compliance with international standards.
- Selective removal of micro-contaminants that could affect mechanical, electronic, or optical reliability.
- Improved adhesion and uniformity in thin-film coatings, metallization, or functional painting.
- Compliance with international industry standards (e.g., VDA 19, ISO 16232) for critical components.
- Full traceability through gravimetric, UV, XRF, or certified particle analysis testing.
Custom cleaning is an engineered process tailored to meet the specific requirements of complex metallic components, homogeneous batches, or highly critical end applications.
Unlike standardized protocols, this approach is based on detailed substrate characterization (alloy, microstructure), targeted contaminant analysis (chemistry, morphology, granulometry), and compliance with technical standards (e.g., ISO, ASTM) or customer specifications.
Critical geometric parameters (e.g., blind cavities, complex shapes) and interactions with subsequent processes (e.g., coatings, heat treatments) are considered to minimize the risk of re-contamination or functional alteration.
- Selection of the most effective decontamination method for each contaminant and alloy.
- Preservation of material integrity by avoiding aggressive treatments that could impair finish or mechanical properties.
- Enhanced functional performance in highly specialized fields (e.g., medical, aerospace) through optimized surfaces for adhesion, biocompatibility, or corrosion resistance.
- Prevention of corrosion phenomena (e.g., pitting, galvanic corrosion) by removing ionic and hygroscopic organic residues.
Spot cleaning is a targeted treatment for removing localized surface defects such as stains, corrosion products (oxides, hydroxides), organic residues, and inorganic deposits.
It restores the functional and aesthetic properties of the substrate while preventing progressive degradation.
- Selective removal of altered surface films (e.g., Fe₂O₃, Al₂O₃, Cr₂O₃, metallic hydroxides) caused by localized corrosion.
- Prevention of subsurface corrosion initiation or propagation (pitting, intergranular, galvanic).
- Improved durability and mechanical reliability through restored surface integrity.
- Enhanced optical and aesthetic properties: cleaner, more uniform, reflective surfaces—ideal for further treatments (painting, passivation, anodizing).
