The Jentner Academy

In the Jentner Academy, you will find training videos, detailed information on electroplating and the key questions at a glance. For the precious metal gold, we have compiled a complete training tool for you, so that you can optimally galvanize with your small electroplating unit in the future. Other electrolytes will follow in the near future.

The training tool is not available on the smartphone. Feel free to watch the training video on your desktop.

In this video, we show you what functionalities the Academy has to offer.

FAQ

In the galvanic baths, evaporation losses must be compensated with distilled or fully demineralized water. The volume must thus always be kept at the same level.

The degreasing has a decisive influence on the quality of the electroplated coating. For this reason, the degreasing must be changed regularly. However, the frequency at which it is changed depends on how much electroplating you do. In case of daily use, the degreasing should be renewed at least every 14 days. For intermittent use, adjust the rotation accordingly. However, if problems occur during electroforming, please react immediately and renew the degreasing bath as a first step.

When degreasing, the old phrase “a lot helps a lot” unfortunately does not apply. If you degrease for too long (the recommended time is 30 to 180 sec), hydrogen can build up in your material and lead to material embrittlement or blistering after electroplating. If the contamination is too strong, you must first degrease with ultrasound (separate device and special ultrasonic cleaner).

Platinized titanium anodes and mixed oxide anodes (MOX anodes) may only be cleaned chemically, e.g. in the ultrasonic cleaner or in electrolytic degreasing. These anodes shall never be cleaned mechanically, i.e. e.g. with the help of a wire brush or by sandblasting, as this will remove the platinum or the mixed oxide. What then remains is the base material titanium, which is a very poor electrical conductor.
Stainless steel anodes may be cleaned in any way, i.e. chemically and mechanically.

When electroplating in a small electroplating unit, you always work by specifying the voltage. The amperage then adjusts itself during the process. The larger the surface area, the higher the amperage.

You can only obtain a reliable result via an analysis in our laboratory. Another possibility for precious metal baths is to calculate the amount of precious metal consumed via the ampere minutes. For this purpose, a value for the theoretical precious metal consumption according to amine is given in our product data sheets. The ampere minutes are obtained by multiplying the amperes by the time. Please contact our sales department for further information.

Instead of applying rhodium, platinum can be used, for example. Platinum also provides a beautiful white color, but is not quite as white as rhodium. We will be happy to send you a color sample if needed.

  • Adhesive gold baths are mainly used for electroplating stainless steel to overcome the passivity of the stainless steel and make electroplating possible in the first place
  • Gold plating baths produce thicker layers with up to 8 µm. We supply these baths in the colors yellow and red
  • With the color gold baths the exact color tone is achieved, e.g. 14 carat color or fine gold color, however, with these baths only very thin layers with 0.1 µm can be deposited
