An advanced chromate conversion process that protects aluminium from corrosion and improves the adhesion of paint coatings.
Aluminium chromating is a process of creating a thin but highly effective conversion coating to protect aluminium surfaces from corrosion and increase the adhesion of paints and adhesives. Unlike anodising, the chromate coating conducts electricity, which allows it to be used in many specialist industries, from automotive to electronics. At our company, this process is carried out using products from the renowned Surtec company, guaranteeing high quality and compliance with strict environmental and industrial standards.
Chromium plating creates a passive protective layer that effectively protects aluminium against aggressive atmospheric, chemical and mechanical factors. The iridescent coating we offer takes on a characteristic blue hue, and thanks to the use of hexavalent chromium-free preparations, it meets the current requirements of RoHS 2, WEEE and ELV standards, making the process environmentally safe and compliant with EU regulations.
The chromate coating provides excellent corrosion protection – it meets the requirements of MIL-DTL-81706B and MIL-DTL-5541F standards, confirmed by a 336-hour neutral salt spray (NSS) resistance test. It can be used as a passivation for magnesium alloys and as a sealant for coatings after anodising. In addition, it has high thermal resistance and is ideal for preparing surfaces before painting or bonding.
The chromating process is carried out on two automated production lines in Murowana Goślina. Our infrastructure allows us to handle parts with maximum dimensions of 4500 x 1500 x 350 mm, which enables both serial production and the manufacture of large individual components. An advanced parameter control system guarantees consistent, high-quality coatings and full process repeatability.
Galwano-Perfekt is expanding its aluminium anodising range with two groundbreaking composite anode technologies: polymeroxid® LF4 LF4 and polymeroxid® xH4® xH4. This is a new standard in durability and protection.
At Galwano-Perfekt, we have been providing chrome-nickel steel blackening services since 2013 on a modern, fully automated production line. We guarantee high quality and excellent aesthetic results even for the most demanding applications.
The new Galwano-Perfekt branch, specialising in anodising, has obtained IATF 16949 certification. This confirms the highest quality of our processes and opens up new opportunities for cooperation with the automotive industry.
