Deposit Thickness in Surface Finishing, the Misunderstood Variable

Deposit Thickness in Surface Finishing

By: J. Lindstedt, President. 

In ordering a surface coating system to enhance the performance of an article in service, the use of standard finishing specifications is the established procedure employed by most manufacturing entities. The specifications most commonly referenced are ASTM, MIL Specs, AMS and unique corporate specifications.

Surface finishing specifications identify a number of parameters which evaluate the ability of the surface coating to perform its intended function. The most common coating requirements used to qualify a coating system are:

Plating Methods & Tooling Design Considerations Part One: Rack Plating

By James Lindstedt, Manufacturing & Process Engineer

Rack Plating Introduction – A Metal Finishing Job Shop

Advanced Plating Technologies is a metal finishing job shop. What does that mean? A metal finishing job shop encounters the metal finishing demands of any industry that has a need for metal finishing. Metal finishing is a highly diverse industry serves the needs  of  a myriad of other industries. Although there is always common ground, every industry has its own unique set of needs and criteria for metal finishing. The conscientious metal finisher must be able to recognize these unique requirements, and reconcile them with the nuances of the plating methods and processes.

Rack Plating & Tooling

When quoting at a prospective job, some of the key factors to consider are:

Rack Plating Gold

  • Part geometry
  • End use
  • Base material
  • Part volume (EAU)
  • Throughput
  • Type Of Process (Electroless, Electrolytic, Immersion Only, etc)

Critical Details Often Overlooked When Specifying a Plating Process

By R. Savija
All specifications for electroplating, whether military, federal, ISO, ASTM or SAE-AMS specifications, have an initial section that contains essential information to be supplied by the purchaser to the electroplater. More times than not, much of this information is omitted from part prints and purchasing documents which opens the door to potential miscommunication and finishing shortfalls. This blog details some of the more common omissions that are discovered by Advanced Plating Technologies’ engineering staff during quoting or contract review of specifying a plating process.

Specification of the plating thickness and tolerance requirements:

Geometric TolerancesOften a minimum/maximum thickness tolerance without a defined checkpoint cannot be realistically obtained with a traditional electroplating process. For example, a plating specification that lists a minimum plating thickness of 0.0003” and a maximum plating thickness of 0.0005” for all surfaces of an electroplated part would not be achievable on most part geometries due to the inherent variations in electrolytic plating distribution.

APT’s Role of US Military Subcontractor Featured in Fifty Caliber Shooters Association Article

US Military Subcontractor ArticleAdvance Plating Technologies continues its role as trusted technical adviser to a number of diverse market sectors.

In our latest profile, The Fifty Caliber Shooters Association’s quarterly publication Very High Power discusses APT’s  role as a subcontractor to the US military, providing specialty plating of a new line of DDI ammunition.  Engineered finishes aiding positive  identification of ammunition types, and withstanding multiple load and unload cycles are key DDI design requirements achieved by Advanced Plating Technologies.

The article further discusses other APT engineered surface treatments used for corrosion prevention and metal on metal lubrication within the ammunition component industry. Read more…

Plating on Aluminum Substrates for Power Transmission/Distribution Applications

Copper as a Design Material in the Power Market

Plating of Aluminum is Key to the Power Market

Plating of Aluminum is Key to the Power Market

The power transmission and distribution industry has long utilized copper as the material of choice for designing and manufacturing critical grid components. Copper has excellent thermal and electrical properties that are desirable when transferring and switching very high power loads. In addition, various alloys of copper available provide the machinability and physical/mechanical properties required for most design applications. Copper not only offers outstanding conductivity but its mechanical properties can be enhanced with a range of alloying metals and heat treatments. Grades such as C101 (oxygen free), C110, C145 (tellurium) and C147 (sulfur bearing), C182 (chromium) and C172 (beryllium) are all cuprous alloys that have been utilized within the power transmission and distribution market for decades. All of these grades are readily plated with conductive metals including silver, tin and nickel to enhance the surface conductivity, reduce the formation of insulating oxides and offer enhanced joinability with methods such as brazing and soldering.
