Purchase order shall specify not less than the following
AMS2422F
Plating thickness desired
Minimum thickness on internal surfaces, if required
Basis metal to be plated
Tensile strength or hardness of the basis metal (this would not apply to Aluminum)
Pre-plate stress relief to be performed by plating processor (time and temperature) if different from 3.1.2
Special features, geometry or processing present on parts that requires special attention by the plating processor
Hydrogen embrittlement relief to be performed by plating processor (parameters or reference document) if different from 3.3
Solderability when required
Quantity of pieces to be plated
Copper Strike
Standard parts are to be plated with either a copper flash or copper strike, unless parts are made of copper/copper alloy containing less than 15% zinc. If these criteria are met, the strike can be omitted.
Minimum thickness of 0.0001 inch (2.5 um)
Nickel Strike is to be done after copper strike
Minimum thickness of 0.0001 inch (2.5 um)
Gold plating done after nickel strike
Minimum thickness of 0.00005 inch (1.27 um) on all surfaces on which gold plating is specified
AOTCO Metal Finishing Adds New Plating on Magnesium Line
AOTCO Metal Finishing, LLC, a leading national provider of specialty finishing services, announced today that it has launched a new production line for plating on...
Electroplating is a process by which one metal is deposited onto a base metal (substrate). These deposited metals offer a variety of benefits including thermal and electrical conductivity, corrosion resistance and more. AOTCO electroplates a wide variety of both standard and exotic metals.
Sometimes called a “conversion coating” Anodizing is an electrolytic process in which an oxide (anodic) layer is chemically built on the surface of the substrate material, providing anti-corrosion and other benefits. AOTCO offers, Type I, Type 2, Type 3 and Titanium anodizing services.
Passivation is a term for a variety if processes that make a metal (most commonly stainless steel) or other substance unreactive, or passive, by altering the surface layer or coating the surface with a thin inert layer. AOTCO performs both citric and black oxide passivation techniques to a range of specifications.
AOTCO plates on a wide variety of Common, Exotic and Non-Metallic substrates, bringing exceptional expertise to magnesium, titanium, beryllium, BeCu, TeCu, tungsten and more. In some cases we pass as high as 450 degrees celsius, allowing for high temperature soldering, brazing, or post machining operations after plating.
Pre-Process: In addition to offering both mechanical & chemical cleaning options, AOTCO specializes in creating solutions for complicated, difficult and tight-tolerance masking challenges. Post-Process: For clients with specialized needs AOTCO offers laser marking and engraving options, including color change caused by chemical or molecular changes, charring, foaming, melting, ablation, and more.
Part of our cornerstone goal of building long-term, collaborative & solution-oriented partnerships, AOTCO will devote reserved physical and human resource capacity for our clients with long-term finishing and deadline requirements. For these partnerships our commitment is that AOTCO manages the process, while YOU control the results.
