Tue, 09 Dec 2014 09:46:27 +0000 http://localhost/business4/?p=41 We’ve written about tank plating on this blog before – the process of plating a metal onto metal items that have been placed into plating tanks. For that process to work, the items to be plated must be electrically charged – in other words, they must be made of metal.

So that leads to an interesting question:

How can metals be plated onto surfaces of non-metallic materials like plastics, ceramics, or composites?

You have doubtless seen non-metallic items that have been plated with metal – they are nearly everywhere. There are metal-plated disposable plastic drink cups, plastic radio knobs, toys with bright shiny metallic coatings, and many other items.

Let’s look at some of the ways that precious and other metals can be coated onto non-metallic surfaces.

New environmentally friendly pre-treatment for plastic plating Mon, 08 Dec 2014 10:02:11 +0000 http://localhost/business4/?p=1 Plating of plastic materials has evolved into a big business, covering huge amount of commercial applications. SAMDOKAN project is focused on the study of the industrialization process of a new environmentally-friendly process of metallization of plastic parts, applied to different sectors: automotive, electrical appliances and sanitary plastic parts.

For activating the surface of the plastic and successfully plating is necessary to employ etching solutions based on carcinogenic chromic acid and toxic Pd/Sn colloids; however these methodologies are subjected to restrictions and disadvantages due to environmental contamination and health and safety related issues.

In an attempt to avoid the use of carcinogenic hexavalent chromic acid in pre-treatments for metalizing plastic surfaces, which will be forbidden in 2017 by REACH regulations, the plastic plating industry is thoroughly investigating new technologies to find alternatives to the use of traditional plating practices.
