Curved Platinum Electrode BMG-034-2 – Platinized Titanium Electrode for Electroplating

Professional Curved Platinum Electrode for Stift, Tampon and Tank Plating

The Curved Platinum Electrode BMG-034-2 is specially designed for electroplating applications where a conventional straight electrode is difficult to use. Thanks to its curved design, the electrode is particularly suitable for working on concave, convex and curved surfaces.

The electrode combines a titanium base with a platinum coating, providing excellent resistance in many electroplating applications. It is particularly suitable for demanding applications involving precious-metal electrolytes such as gold, palladium and rhodium.

The curved geometry allows the electrode to be positioned closer to the shape of the workpiece and can help achieve a more uniform current distribution and coating.

Why Use a Curved Platinum Electrode?

When plating curved workpieces, a straight electrode can result in an uneven distance between the anode and the workpiece.

This can lead to variations in current distribution and therefore differences in coating thickness.

The curved design of the BMG-034-2 allows the electrode to follow curved workpiece geometries more effectively.

It is particularly useful for:

  • Rings
  • Curved metal components
  • Bowls and concave surfaces
  • Reflectors
  • Round components
  • Decorative metal parts
  • Complex-shaped workpieces

The curved geometry makes it easier to reach surfaces that are difficult to plate evenly with a conventional straight electrode.


Platinized Titanium Electrode

The electrode consists of a titanium substrate with a platinum coating.

Platinized titanium electrodes are widely used in electroplating where a durable and highly resistant electrode surface is required.

This makes the electrode particularly suitable for demanding precious-metal plating applications where contamination of the electrolyte should be minimized.


Ideal for Precious-Metal Electroplating

The curved platinum electrode is particularly suitable for applications involving:

  • Gold electrolytes
  • Palladium electrolytes
  • Rhodium electrolytes
  • Silver electrolytes
  • Other compatible electroplating electrolytes

It can therefore be used for both decorative and functional surface-finishing applications.


Ideal for Pen Plating and Tampon Plating

The special curved shape makes the electrode particularly useful for selective electroplating.

Typical applications include:

  • Local gold plating
  • Gold plating repairs
  • Silver plating
  • Palladium plating
  • Rhodium plating
  • Touch-up plating
  • Repair of damaged coatings
  • Plating of small areas

The curved electrode can provide a significant practical advantage when working on complex or curved surfaces.


Also Suitable for Tank Plating

The electrode can also be used for suitable tank-plating applications.

When used in a plating tank, the electrode should be positioned so that the distance between the anode and the workpiece is as uniform as reasonably possible.


Application

1. Prepare the Workpiece

Thoroughly clean and degrease the workpiece. Depending on the base material, suitable activation and/or an appropriate undercoat may be required.

2. Position the Electrode

Position the curved electrode so that its geometry follows the workpiece as closely as practical.

3. Connect the Electrode

Connect the electrode to the positive (+) pole of the appropriate plating power supply.

The workpiece is connected as the cathode to the negative (-) pole.

4. Use the Appropriate Electrolyte

Always use an electroplating electrolyte suitable for the desired coating metal and substrate.

5. Electroplate

Use the voltage and current parameters specified for the particular electrolyte. During pen or tampon plating, move the electrode evenly over the area being plated.

6. Clean After Use

After use, clean the electrode appropriately and remove electrolyte residues.

Do not use abrasive cleaners or abrasive materials, as these can damage the platinum coating.


Professional Accessory for Precision Electroplating

The curved platinum electrode is particularly useful for users who require better adaptation to workpiece geometry during pen and tampon plating.

Combined with a suitable anode holder and anode pad, it provides a professional setup for selective and localized electroplating.
