PRODUCTS & SERVICES
Our plating services including zinc nickel, zinc cobalt, trivalent chrome, nickel chrome, hard chrome, silver, gold, tin, tin cobalt, brass, anodizing, trivalent chromating and many others.
Metals may also be coated with gold for ornamental purposes.
For less demanding applications in electronics, silver is often used as a cheaper replacement for gold. Silver is actually a better conductor than gold.
Historically, silver plate was used to provide a cheaper version of items that might otherwise be made of silver, including cutlery and candlesticks.
Chrome plating is a finishing treatment utilizing the electrolytic deposition of chromium. The most common form of chrome plating is the thin, decorative bright chrome over an underlying nickel plate. When plating on iron or steel, an underlying plating of copper allows the nickel to adhere. The pores (tiny holes) in the nickel and chromium layers also promote corrosion resistance. Bright chrome imparts a mirror-like finish to items such as metal furniture frames and automotive trim.
Hard Chrome Plating
Thicker deposits, up to 1000 Ám, are called hard chrome and are used in industrial equipment to reduce friction.
Zinc coatings prevent oxidation of the protected metal by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate's surface integrity as it is formed. Indeed the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers.
The tin-plating process is used extensively to protect both ferrous and nonferrous surfaces. Tin is a useful metal for the food processing industry since it is non-toxic, ductile and corrosion resistant. The excellent ductility of tin allows a tin coated base metal sheet to be formed into a variety of shapes without damage to the surface tin layer. It provides sacrificial protection for copper, nickel and other non-ferrous metals, but not for steel.
Tin is also widely used in the electronics industry because of its ability to protect the base metal from oxidation thus preserving its solderability. In electronic applications, lead may be added to prevent the growth of metallic "whiskers" in compression stressed deposits, which would otherwise cause electrical shorting.
