Plating gives a good finishing
We have drum and hanging methods in use in plating. The pieces for drum plating are normally from some millimeters up to some centimeters in size. In hanging method the largest single piece possible is 450 x 100 x 350 mm.
We plate brass, copper, stainless and other steels with copper, nickel, silver and gold by using electrolytical and / or chemical methods.
We also anodize aluminum. Black nickel plating is the latest service we provide.
Anodizing – corrosion resistance and longevity
Anodizing, or anodizing, is a metal surface treatment that increases the natural corrosion resistance and longevity of metals. Anodizing creates a protective oxide coating on the surface of the metal with the help of an electric current.
Colors: black / natural grey
Black nickel – spectacular shine and corrosion protection
Nickel plating is well suited for pieces that want to have a spectacular shine and that want to be protected from corrosion. Nickel is also used in many objects as it is. The nickel surface is hard, durable, has a pleasant appearance and provides durable protection for the base material.
- Below the black nickel finish, a nickel coating is applied, which provides protection against corrosion
- stylish black visual coating
- thickness from one micron to two microns (1-2µ)
- for brass, copper as a first coating
- usually covered with a nickel-gold coating
Silver plating – electrical conductivity and performance
Silver has the best electrical and thermal conductivity of all metals. Silver plating is very suitable for pieces that require better corrosion resistance than, for example, copper. Silver is a very solderable metal and has antibacterial properties.
The silver coating gives the piece good electrical conductivity and reflectivity, and silver improves the product’s appearance and visuals.
Passivation of Aluminum
Passivation of aluminum is a chemical coating process in which a passivation layer conforming to the RoHS directive is formed on the surface of the aluminum. The color of the passivation surface layer is almost colorless.
The surface layer gives the products good corrosion protection, heat resistance (350 °C) without compromising the corrosion protection properties. Anodizing works as a good adhesion platform for paint surfaces. Passivated aluminum can withstand the high temperature required by the powder coating oven.
Characteristics
- provides a good basis for the painting
- the surface remains good when stored
- electrical conductivity remains good
- excellent corrosion protection and heat resistance
Gold plating – one of the most important nobel metal coatings in the electronics industry
Gold (Au) is one of the most important precious noble coatings in the electronics industry. Gold plating significantly improves the corrosion resistance of components. The gold coating prevents the piece from oxidizing, so that, for example, the solderability and electrical conductivity of the connectors remain better. Gold coating is used e.g. in measuring devices of different technologies due to gold’s excellent infrared reflectivity.
Gold plating can be done directly on most electrically conductive materials.
We use Fisherscope X-ray System XDL in our quality control and we have a device to control the thickness of anodizing as well.
