  • Plating Plastics And Other Non Conductive Surfaces

    Plastic or many other item that is a non-conductor has to be made conductive for a plate to adhere to its surface.

    Silvaspray is designed to bond tenaciously to most plastics. It will also cover most other nonconductive materials, giving good adhesion.

    Connect wires to the part to be plated, in order to conduct electricity to the part for plating. It is important that you do this PRIOR to coating, to enable the coating to make contact with the wire.

  • Zincating Aluminium Prior To Electro/ Electroless Plating

    Aluminium forms an oxide the moment it is exposed to the air. This presents a problem when plating it, as the oxide prevents the plate from sticking. By using the Zincate process as a pre-plate dip, you chemically remove the oxide layer and at the same time, apply a layer of zinc. The zinc protects the aluminium from further oxidising until it is ready to be plated. As the part is lowered into the plating tank, the zinc is etched away by the solution and plating proceeds onto a clinically clean surface.

  • Instructions For Plating Baby Shoes

    Plastic, being a non-conductor, has to be made conductive for a plate to adhere to its surface. SilvaSpray or the new water based copper conductive medium (CCM), (CCM requires an immersion in the Caswell Immerse Tin Solution tank), is designed to bond tenaciously to most plastics. It will also cover most other nonconductive materials, giving good adhesion and provide the metalisation required. Connect wires to the part to be plated, in order to conduct electricity to the part for plating. It is important that you do this PRIOR to coating, to enable the coating to make contact with the wire.

  • Remove Old Chrome

    A good alkaline cleaning solution is prepared with 5-6 oz. SD ANODISE & CHROME STRIPPER added   to one gallon, or 4.5 litres of water. This solution may be used at room temperature but the stripping time is slower. Heating the alkaline solution to a Temperature of 160ï F, considerably increases the rate of chrome removal. The brush plating technique is ideal for use with this solution, especially for decorative chrome plate removal. A typical set-up for stripping Chrome plate electrolyticly using SD ANODISE & CHROME STRIPPER solution is shown here.    

    The recommended procedure is as follows:    

  • Using Chromates to Colour Chrome

    CHROMATE PROCESSES 

    Chromating is a process used primarily on zinc plating, zinc die-casting (pot metal), and cadmium plating. ‘Golden Cad' is really a cadmium plate that has been ‘chromated’ with a yellow chromate.

    Zinc and cadmium are electroplates or metals which are readily attacked by mild acids, and will deteriorate rapidly, even if daubed lightly with tomato ketchup! To 'harden' the plate it is placed in a mild solution of special acid (Yellow Chromate, Blue Chromate or Drab Olive Green). This slightly attacks the plate, oxidizing it. The oxide forms a tough corrosion resistant crust, which protects the softer zinc

  • Plating Die Cast Model Cars

    Zinc die-castings have, until now, been a difficult material to plate for the small operation. The metal is given to oxidising and suffers from being exposed to acids of all forms including Tomato ketchup. Die-casting manufacturers have used dangerous chemicals and cyanide copper plating systems to clean, prepare and plate the parts, making it almost impossible to do this on a small scale.

    This new kit has completely resolved this problem, by using a new commercial grade system of etching, cyanide free copper plating, and finally plating with our famous Copy Chrome system. The system will also plate pewter, lead,

  • Dip Plating With A Plug N Plate Kit

    Sometimes it is much easier to simply dip the part into the solution to plate it, especially if it is small with lots of detail. The Plug N' Plate® power supply and plating wand can easily be used for this procedure. Pour all of the plating liquid into a small wide necked container, such as a glass or 300ml plastic tub. Place the plating wand into the solution and clip it to the side of the glass with a clothes peg. Attach the work piece to the negative alligator clip and suspend the part into the solution. If you wish

    The following solutions are available for use with Plug N’Plate® adapters

    General Setup

    The Plug N’ Plate® Regulated Power Pack for Brush Plating is 1.5v to 12v DC variable @ 500ma and has two terminals. The red plug or the red alligator clip fits into the open end of the plating wand. Sometimes the red plug may be a little loose, but this can easily tightened by placing the plug into the wand, then gently squeezing the wand case with a pair of pliers, until the fit is tighter. The black alligator clip is attached to the work-piece.

  • Using Batteries For Power Supply When Plating

    There are many choices of power source, all of them being able to cope well with most applications. All our kits, except Chrome and Copy Cad, will work well from a car battery or a battery charger. Even a cheap 2 amp trickle charger will plate surfaces of up to 30 square inches, which is sufficient for many of the small parts likely to be plated in our operation. If you decide to use a rectifier, you need not be concerned at to how you are going to control the power, as these units have built in rheostats. But, if
