The new shop at Tecan is completely 'air-free' and following is a list of the processes benefiting from Serductor agitation and filtration systems supplied by Serfilco: Silver; Pure Gold; Acid Gold; Electroless Nickel; Nickel Sulphamate; Acid Copper; Tin; Tin/Lead; Type 1 Hard Anodising; and Type 2 Sulphuric Anodising.
One was a simple sulphuric acid based nickel strike, which possibly would require a slightly higher operating current, and the other was a nickel sulphamate strike.
Finishes available include acid gold, pure gold, silver, bright tin, 60/40 tin lead, 90/10 tin lead, sulphamate nickel, electroless nickel, copper, Type 1 sulphuric anodising and Type 3 hard anodising (colours to specification), stainless steel passivating, and Alochrome 1200 chemical blackening.
In-house plating finishes include tin, electroless nickel, sulphamate nickel, 60/40 tin lead, silver, copper, Alochrom 1200, and Types 1 and 3 anodising (decorative and hard) gold plating is also available at a set additional cost.
A different problem exists in the sulphamate solution especially when used at high concentration (eg.
Typical solutions used in these machines are soak and electrocleaners (low foaming), copper plating (less common nowadays) and sulphamate nickel.
