LHCO has the experience and the technical knowledge to perform a variety of surface finishing processes, with the highest quality standards. These processes are Electroless (Chemical) Nickel-Phosphorus, Electroless (Chemical) Nickel-Phosphorus-Teflon, Zinc-Nickel Plating, Electrolytic Nickel Plating, Gold-Cobalt Plating, Tin Plating, Silver Plating, Copper Plating, Anodizing, Chemical Conversion Coating on Aluminium and Passivation of Corrosion Resistant Steels.
We were pioneers in the application of Electroless Nickel-Phosphorus at industrial scale, targeting from our beginning the aeronautic industry, as well as other industrial sectors as: electronics, automobile, food industry, moulds, hydraulics, etc.
We pay our attention to detail, since we are used to work with precision and we can fit to any specification. We make it our business to understand the customer needs, what he wants and why he wants it. With the aim to find the best solution for our customers, we offer consulting and advice for a complete range of finishes and processes.
ELHCO is a company born and raised with a commitment to carry out their activities within the larger standards of quality and environment. Besides the different quality certifications, Elhco also received an award as “a model company for environmental protection”, awarded by Catalan Government.
ELHCO interested not only to offer the best service, but also to always be up to date with the latest developments in the field of coatings technology. This is why we maintain a close collaboration with various research institutions such as:
Catalonia Institute for Energy Research (IREC)
University of Barcelona (UB)
Universitat Politècnica de Barcelona. BarcelonaTech (UPC)
Autonomous University of Barcelona (UAB)
ur ability to achieve challenges, to reach the technical limits and applying new methods have led us to collaborate with research projects such as “Investigation of a new polyarticulated robotic arm with movement controlled by variation of the radius of curvature” or the project “ATON: Research and development of new technologies for power generation based on thin film photovoltaic cells”.
