Brass and zinc based die cast substrates are commonly used in several industries including for sanitary items and household fittings. These substrates are typically coated to give an attractive appearance as well as wear characteristics to increase the longevity of the article. For the sanitary industry especially, a common coating is formed through a combination of electroplated nickel and chrome. This gives good wear and corrosion resistance as well as the familiar chromium appearance we are all used to.
Ensuring that parts are properly prepared before plating is essential to ensure the quality of the finished articles. Using best practices for the pretreatment process means that substrates are sufficiently cleaned and activated leading to good adhesion and quality of the subsequent plated layers while ensuring minimal substrate attack or degradation of the finish.
This webinar will give an overview of the pretreatment of brass and zinc based die cast parts before decorative electroplating processes and advice on best practices gathered from decades of industrial experience.
