High-tech
equipment and components are barely conceivable without precious metals. Smaller
mobile phones, smaller computers, more power in less space. Ögussa commercial
plating's mission and commitment is to achieve the highest quality combined with
sparing use of resources. The comprehensive work spectrum covers purely technical
applications as well as classical decorative coatings. This area has been developed
intensively over the last few years.
The
finishing of components generally comes at the end of the production chain. Because
of this, problems frequently arise which could easily have been prevented with
a structure "suitable for plating". Is the component suitable for a drum or has
it been developed as rack goods?
Drum
goods, especially small and very small parts, can be coated very economically
because the goods carrier need not be fitted with threading wires or pins.
Not
every geometry is suitable for this type of manufacture; in this case contact
zones can be provided in defined areas which allow quick and economical fitting.
Holes and internal threads are especially suitable for ensuring process safety
during the desired bath sequence. The bath sequence is obtained from the desired
layer structure .

At porous
soldered
joints between hollow bodies there is the risk of penetration from
the degreasing bath and then the electrolyte.
The sensitive high-performance electrolyte can be destroyed. Liquid generally
diffuses through these pores a long time after the plating and becomes noticeable
as a result of unsightly spot formation (sweating)
Only
the correct combination of basic
material and precious metal coating yields the perfect result.
The aim is to considerably improve the material properties - corrosion resistance,
electrical contact resistance, conductivity and solderability.
This
is just a short extract from the mission and scope of precious metal plating.
