TECHNOLOGY
Innovation, control
and quality
For over 60 years, Deltar has specialised in high-phosphorus electroless nickel plating treatments and, in particular, silicon carbide (NiSiC) and Nickel-PTFE codeposits, designed to protect and enhance the products treated.
Our plants and processes are designed to guarantee consistent results compliant with the most demanding specifications, for companies active in numerous industrial fields, from Oil & Gas to automotive, through food and up to aerospace.
The pillars of our company
PLANTS
Latest-generation industrial plants
Deltar has a complete range of technologies to address any production need with maximum flexibility and precision:
- Plants for small and large parts, both rack and barrel, able to treat components from a single gram up to 58 tonnes and over 5 m in length;
- Acid-free nickel stripping plant, which removes the nickel coating while preserving the integrity of the original surface;
- Heat treatment furnaces up to 700 °C, used to stabilise and optimise the mechanical and chemical characteristics of the coatings;
- High- and low-pressure sandblasting plants, to prepare or finish surfaces before and after treatment;
- Low-pressure microfiltration with high hourly turnover, to maintain optimal purity and performance of the treatment baths;
- Dual thermal power station, for production continuity and no plant downtime;
- Complete digitalisation of production and management processes, with on-site and off-site remote control, in line with the principles of Industry 4.0.
LABORATORY
In-house laboratory for quality control
Our in-house laboratory supports every stage of the processes with state-of-the-art instruments and verification methods:
- Microscopic analysis of the chemical-physical characteristics of the deposit, to assess thickness, uniformity and adhesion;
- Corrosion testing in a salt spray chamber, to simulate aggressive operating conditions;
- Roughness gauges and microhardness testers (fixed and portable), to determine surface finish and hardness;
- Metallographic section and laboratory lapping machines, to prepare and assess sample sections;
- Bend test, to check the mechanical strength of the coating.
This integrated approach guarantees that every treated component meets the specified standards and offers high, long-lasting performance.
Our certifications
To guarantee maximum reliability and sustainability of our electroless nickel plating treatments and surface coatings, Deltar processes comply with the main international reference certifications, which we are committed to renewing periodically.
