Plating Division products

The Plating Division of the LEGOR GROUP offers a skilled and innovative solution to the various galvanic requirements.


Precious metal compounds represent the initial building blocks to the precious metal electroplating industry. They are the very fabric from which an electrolyte is born making the purity of these elements critical. Legor Group offers a range of compounds in the form of salt, chemical solution, and other formulated material specifically designed for efficient electroplating baths.  These compounds cover the most important and commonly used elements within the Platinum Group Metals, as well as variations of gold and silver complexes widely used in the plating sector. Purity and consistency are critical factors in production control therefore the highest purity precious metal substances are used along side reagent-grade catalysts. These elements are key factors that drive reliable and repeatable plating. 


Electroplating is the process of covering an object with a thin layer of metal by electro-chemical deposition. Bath plating otherwise know as immersion plating is the most common and conventional form of electroplating. The chemicals used in this process are referred to as plating solutions or electrolytes.  Legor Group develops and manufactures all of our precious metal electrolytes designed for this process with great pride. From the research and development stage, on to the production process, and finally straight through to our world wide distribution network, we do our best not to miss a single detail in our entire  product supply cycle. Precious metal is our specialty and at the heart of the Legor Group Plating Division.  Our product portfolio covers the most commonly used plating solution, to the most advanced precious metal electrolytes available on the market today. Our immersion plating products are designed to meet either technical or decorative plating requirements and are available in an extensive range of colors. 


Pen Plating or stylus plating is an electro-deposition process designated to plate small design spaces, preform repair work, or plate small touch-up areas. Depending on the relative area, accent and detail work is difficult to do with immersion plating solution as the time required to apply plating masking can lead to a loss in productivity. Pen plating presents itself as a perfect solution to this problem. Legor Group pen plating solutions are highly concentrated chemicals specifically designed for the pen plating process. Prior to a product release the solution must fair well in meeting the following criteria:

  • Deposition Speed
  • High Luminosity Level
  • Color Accuracy
  • Limited Bubble Development
  • Low Tip Consumption 

The precisely balanced chemistry of the pen plating solutions make them extremely effective in yielding good results.


Passivation and coating technology is conceived to assist with oxidation protection or to improve wear resistance of metallic surfaces. Legor Group is very keen to offer suitable solutions to advance these characteristics common to plated and non-plated metallic substrates. We offer a selective line of products using diverse technologies, specifically studied to protect surfaces from external degradation. 
E-Coating: is a process that deposits a cross linked organic polyurethane or acrylic coating to any suitable pre-treated electrically conductive substrate. It is applied by the means of electrophoretic deposition. Coatings can be clear or coloured, translucent or opaque, and have uniform thickness over the part, typically in the 10-20 microns range. Heat treatment in an oven also known as the curing phase is what centres the particles providing the coating with durability.
Chemical Passivation: refers to a material becoming "passive" and being less affected by environmental factors such as air or pollution. Passivation is the generation of a shielding layer comprised of oxides which protects the surface that it is applied to from corrosion. A passivation layer is typically 10 nano-meters thick and completely invisible to the naked eye not altering surface color or reflectivity.


Troubleshooting plating problems can always seem challenging.  The ideal brilliant and luminous  finish is all too often interrupted by black and brown spots, surface discoloration, or a dull plating finish. In actuality, there are a limited number of variables that need to be monitored in achieving consistent quality in a plating deposition. The largest percentage of surface defects can be prevented simply by following the proper cleaning procedures, making the most important factor in achieving good results, the proper preparation of the work piece before plating.  All pre-treatment steps are essential to follow and execute properly in order to obtain premium quality plating throughout the entire process.
Legor Group offers a complete line of pre-treatments for plating, composed of the highest quality chemical compounds, granting consistency in plating deposition results.


When searching apparatus intended for electroplating, there are three primary variables that must be defined.
Voltage is a key factor that brings the galvanic process to life in the form of electric current. This stresses the importance of a DC rectifier with precise current output. If the current efficiency is too high, the deposition velocity will increase, but it will also increase the risk of a porous surface or a dull color. If the current is too low, uneven bonding will occur and the entire deposition process will slow significantly. To circumvent these universal issues, accurate voltage is essential.
Heat is a variable that can assist in cathode efficiency in turn giving you a faster plating deposition speed and in some cases activate a solutions aptitude to be luminous. For these reasons it is crucial to have an accurate heating element. Overheating can result in a poor color, accelerated evaporation, and cause unnecessary fuming. All of which can be avoided with a heating source that is able to maintain a consistent temperature.
The anode completes the electrolytic circuit in electroplating.  In precious metal plating, a refractory metal such as titanium is typically coated with platinum creating a corrosion resistant element that allows for a extremely pure plating deposit. The quality of the plating deposit, is highly reliant on the quality of the anode used.
With these three key variables in mind, Legor Group offers a wide range of equipment and instrumentation for electroplating to cover both pen plating and bath plating applications. With a strong focus on the critical details, our range of plating machines and accessories have been developed to suit the needs of plating operators worldwide, from first time electroplaters to long-time plating experts.
