What to Consider before you Electroplate

Are you thinking about having parts electroplated?  Here are the most important things you need to take in to consideration before and during the process…

What should you consider Pre Electroplating?

 

  • Nesting

Electroplating involves electrical and chemical reactions on the surface of the part you are wanted to be plated, so exposure is crucial to the result of the final product.  Parts which are nesting will lack adhesion and therefore coverage on the final product.

  • Tolerance

The tolerance on vital dimensions on the part in question should be designated with the plating thickness in mind.  This is should be accounted for when the pieces are ready for assembly after the products have been through the chemical process.

  • Environment and exposure

What is your product going to be exposed to?  A high amount of friction, heat or sea spray?  This is essential for negotiating the thickness of the necessary plating required to maintain the resistance, corrosion and rust protection of the part in question.

  • Geometry

Electroplating involves using a current in order for the reaction to be initiated on the surface of a part, which means that the geometry of the parts surface will influence the distribution of electroplating across the surface.  This is called current density.  It is normal that plating builds up in parts which have sharp corners, bends and threads but it can be prevented if specialists use advanced plating processes.

  • Drainage

The preparation of the surface of a part needing plating must be correct so that the inside surfaces of a part will be sufficiently covered when the process is completed.  This is so that the plating will have the correct bond strength for plating to have been carried out correctly and for the part to have ultimate protection and increase its longevity.  This, for some parts, may mean they need to have a weep hole create during their design phase, so that this can be achieved.

  • Usage

It must be clear what your intended use is for the part you are needing plating.  Make it clear to your specialists what the use and required characteristics are of the part.  Important features include conductivity, low friction, high strength, corrosion resistance, wear, exposure to sea spray or water etc.  This will determine which metal your part is made from (eg. Copper, Nickel, Tin, etc), how your part should be finished and plated.

Electroplating from the Start

electroless-nickel-plated-componentElectroplating is a form of metal plating which is used by many industries in a range of capacities which include the aerospace, automotive, army, space, medical, electronic and engineering sectors, to name but a few.  It is useful due to the fact that it is so versatile and lends itself so because of its electrochemical process where metal ions in solution are bonded to metal substrates by means of electrodeposition.

Before Electroplating

Pre Electroplating, all parts must be thoroughly cleaned and then a process of chemical baths must be followed so that the parts can be prepared and activated so that the adhesion for the strong bond can take hold and become effective.  This is key in the electrodeposition process.  Many variables must be monitored closely during the electroplating bath process, such as the power supply which provides a direct flow of current to the parts in submerged.  This enables ions to be attracted to the surface of the metallic part evenly.  Every mole of electrons that are transferred to the part, allows one mole of metallic ions in the solution to adhere to the part during the bath process.  A chemical reaction can subsequently occur where the reduction and oxidation of ions takes place.

Types of Electroplating

Specialist plating facilities are able to plate a large array of different base materials to protect various surfaces.

Base materials for electroplating include:

  • Brass
  • Copper
  • Nickel
  • Stainless Steel
  • Nickel Silver

Surface finishes for electroplating include:

About Electroless Nickel Plating

Electroless nickel plating is a high quality but cost effective coating solution which can drastically extend the life expectancy of a stainless steel component.  This is due to the metal layer deposited by the electroless nickel coating creating an even thickness across the components surface, despite its shape.  This makes electroless nickel plating very popular in sectors such as the defence, health, automotive and aerospace industries.

Wheelie Fallen in Love with Copper Plating

It has recently appeared in the news that Ted Baker have teamed up with the famous bicycle producers, Quella.  Together, they are set to create three stylish bespoke models which are predicted to outdo Santander Cycles.  Each of these three new bicycle structures feature copper plating, steel frame, and will have a Brooks England leather saddle.  The bikes will be available in red, green and blue and have been named after fish due to the bikes being inspired by the ability salmon have to swim upstream – Redfinn, Bluetail and Greengill – Well, for the £1,995, you’d expect a pretty name, wouldn’t you!

About Copper Plating

Copper plating is used for both functional and decorative reasons.  Traditionally, it is used for electroforming but can also be used for Electro Magnetic Interference (EMI) and Radio Frequency Interference (RFI) shielding purposes.  The reasons for this are because copper is a brilliant conductor and its deposits from copper plating are very bright.  It also has excellent levelling properties and naturally kills bacteria which is why it is used so frequently in laboratories to plate medical equipment.  The aesthetics of copper plating are used due to its bright, highly polished copper-pink appearance which can be lacquered in order to prevent the copper plating from becoming tarnished if it is intended only for decorative purposes.

The Future’s Bright, The Future’s NiTEC

LED_lights

2008 saw the beginning of the EU process which took four years to put in to place, preventing incandescent light bulbs from being sold.  This was because they performed inadequately and were not eco-friendly due to the high amount of electricity they consumed.  The LED has therefore taken its place on our supermarket shelves, as they are proven to be much more efficient.

Plating Industries

The electronic and automotive industries, as well as most British households and road engineers for road lighting applications, are using LED lights.  The LED substrate can be silver plated either conventionally by rack or less conventionally by reel-to-reel plating procedures.  Plating differs depending on the thickness, and ranges from 20 to 150 A/dm², normally.

Bright Lights

How are LED lights so bright?  This is due to a low free-cyanide silver process which contains brightener additives.  This creates high luminosity.  These LEDs are much more eco-friendly, cost effective and use a fraction of the amount of electricity of an incandescent light bulb.

Heat Treatment gets the Deep Treatment

The silver deposits used to plate the LEDs were initially heated for 60 minutes at 200° and then for 120 minutes at the lower temperature of 170°C but it was quickly identified that significant reflectivity was lost during this.  So it was decided that a post-dip was going to be used in order to prevent the reflectivity loss, in the form of an aqueous treatment post heat treatment.  This seems to have worked, having been tested on multiple different types of nickel, at higher temperatures and with the nickel being treated for shorter lengths of time (up to 1 minute), as the GAM measurements do not diminish dramatically at all.  Thus, proving the effectiveness of the combination of plating, heat treatment and the post-dip aqueous treatment as a trio.
