We advise you to go to the new webpage about Galvanising or Chemical treatment.
The galvanic treatment consists of degreasing, electroplating, polishing and insertingthe necessary materials. Depending on the type and size of the series, not all steps are done in one procedure. What kind of treatment is used depends on the type of product,the processes and the quantity of process. Below some treatments with several steps inthe electroplating process
The scouring process
To make a thin layer of metal on the synthetic material to bring on it is necessary tomake a good adhesion. The surface should be cleaned from oil, dust, grease, water.
These are the parts through the use of release funds in injection molding machines anddue to storage and transport. Because of negative effects on the degreasing process, it is important to the bath, which will be degreased, continuous clean to prevent particlescome off later. There are several effective methods to process chemicals to clean. Aftermake a filtration process to remove particles, ion exchange of cations, anions anddissolved capillary active agents used to remove parts of the solution. Ultrafiltration is also used to remove dissolved solids.
do not use silicone release agent
Release agents, silicon can not be removed with make a degreasing process. It is onlythrough mechanical processing, grinding and polishing. This is very labor intensive.Discuss with your moulder absolutely no silicone release agent is used
For corrosive particles that may be able to sit in the synthetic material from the part to be removed. For this purpose, strong acids used. The metal will turn into make a acidreaction. After the process, the rest of the acid must be removed by water, the water must be neutralized.
The bath in which the process is established must be perfectly clean metal hydroxideand other compounds, by precipitation. Depending on the process there are severaltypes of metal compounds that can be separated. Especially in the galvanic processwhere precious metals are used, it is useless agglomeration valuable. Generally it willbe collected and treated by electrolysis, to the (noble) to recycle etal.
Problems the substances toxic cyanide compounds, which also can be found in thehydroxides. The high amount of metal ions in the galvanic bath are also make aenvironmental problem by galvanic behandiling afvalverwijdering.Daarom is not a cheapprocess.
Because to the flush after each production step is the flushing volume and highcontaminated by various kinds of chemical products. For to treat the water, havechemicals, acids or bases and sediment are also removed.
