Plastics and Difficult Substrates
Some of the earliest patents for plating
on plastics were owned by Epner Technology. They were for
gold plating plastic military buttons and insignia thus saving
millions of pounds of brass desperately needed for World War
II shell casings. Today Epner specializes in plating a variety
of di-electric materials including the engineering plastics
such as Ultem™, Teflon™, Ryton™ and Torlon™…and
of course ABS.
Epner is also known for blister-free plating
on some of the more unusual or difficult metals, permitting
them for example, to withstand high brazing or soldering temperatures.
Titanium, Molybdenum, Tungsten, Magnesium, AlBeMet and Beryllium
are some of the more difficult substrates routinely handled
by Epner”s thoroughly trained platers.
