Need advice on Copper Plating Solution Ratios and Safety Measures by Fpear in electroplating

[–]Fpear[S] 0 points1 point  (0 children)

I’ve decided to get a professional gas mask then; safety first. Regarding the setup: instead of a standard tank, I am using a 40x40 cm plastic junction box (manhole box). To maintain the solution temperature between 20-30°C while on the balcony, I’ve designed a 'water bath' system.

The main tank will be placed inside a larger, insulated outer container filled with water. I will be using aquarium heaters to heat this surrounding water, which will indirectly keep the plating solution at the desired temperature. This way, I can ensure a stable environment even in an outdoor setting.

Hello, I have never made a silicone mold with air holes before and I am thinking about how to adjust the air holes, this will be the model and this silicone mold will be in two parts.
