In addition, the use of these state-of-the-art facilities has favoured the containment of industrial costs, enabling the company to have higher quality products at balanced and affordable prices.įor more information visit: www.palazzani. Thanks to this important change, has managed to transform itself into an Industry 4.0 company that can boast prestigious quality and conformity certificates for both product and process issued by the strictest international certification bodies. The trivalent chromium-plating plant uses a futuristic low-energy consumption purification plant for the recovery and purification of all waste that, once checked, is reintroduced into the production cycle in full compliance with the most stringent regulations on the subject and under the scrupulous supervision of a highly qualified technical staff. In contrast, trivalent chromium (Cr III), in addition to guaranteeing the same characteristics of durability and aesthetics of the products, makes the chromium-plating process totally compatible with the health of workers, consumers and environmental protection. In fact, has decided to purchase and install a trivalent chromium plating plant for its products: hexavalent chromium (Cr VI), in fact, was found to be toxic, with mutagenic and carcinogenic effects, and its use in industry was only allowed following specific authorisations by the European Union. We are an ISO 9001 and ISO 14001 certified plater based in Leeds, West Yorkshire and are happy to answer any questions you might have about is a Made in Italy manufacturer of taps and shower systems with over 100 years of history, which has chosen this year to face an important change in terms of safety, environmental compatibility and sustainable technological progress, in perfect coherence with its corporate values. We are still offering both processes for those customers who require Hexavalent, but longer term we expect all of our Zinc Plating will be Trivalent based. Snyder Atotech USA inc., Rock Hi//, SC Electrodeposition of decorative chromium is the principal means of imparting the physical and chemical properties of chromium to the surface of less expensive and easier-to-form materials such as steel and plastics. ![]() We are currently phasing out our use of Hexavalent Chrome within our Zinc Plating offering in order to comply with REACH protocol. We would expect the performance of Trivalent based plating to match that of its predecessor. As such we have independently tested the quality of our Zinc Plating which incorporates Trivalent Chromium, and have seen it perform up to 1500 hours under ASTM salt Spray Tests. hexavalent chromium to Trivalent Chromium. As such you would expect that Zinc and Clear will now have a light iridescent blue colour to it.Īs with any other process, Silchrome are always keen to test the expected results. Another fundamental aspect is that it offers a colour rendering (yellow). In many cases a dye will now be used to create a desired colour. Now, with new Trivalent Chrome the colours that are produced are actually a ‘weaker’ colour in tone, but this is not connected to the performance of the coating. In the past the yellow colour was actually created through the use of the hexavalent solution and the ‘stronger’ the colour, the more hexavalent chromium that was used. These include: Blue, Yellow, Black and Olive Drab. Most people who are familiar with Zinc, will be used to the range of different coloured passivates which are used in the process. This means where you have a larger volume of smaller parts that need Zinc Plating, this process can be carried out more cost effectively. colored chromate, and Zero Chromium SB has similar tones to black. It’s also possible to Barrel Plate with Trivalent. As hexavalent chromium, which is contained in chromate filming agents used in zinc plating. ![]() Zinc Plating using Trivalent Chromium has a higher efficiency with more uniform distribution. ![]() The small switch to Trivalent Chromium has big impacts on production. As such leading chemical manufacturers have sought to find a way to replace hexavalent chrome whilst obtaining the same levels of protection. Hexavalent Chrome is an element in processes including Zinc Plating. On the 21 st September 2017, Hexavalent Chrome will be subject to increased restrictions after being placed on the European Chemicals Agency’s Annex list for some time. Hexavalent Chrome (chrome VI) is a known carcinogen, meaning that it’s bad for the environment and for our staff carrying out the process. The way in which Silchrome carry out our Zinc Plating process has been updated, and we are now offering Zinc Plating that uses Trivalent Chrome rather than Hexavalent. Zinc Plating is also known as galvanising and can be passivated in a number of colours. It’s a sacrificial coating that offers excellent corrosion resistance at a cost effective price. Zinc Plating is a very popular process for the protection of a wide range of components.
