Contact-systems and accessories for electroplating equipment - 1

Electroplating baths with high current densities are normally high energy consumers. Ensuring a consistently high quality of the coating, energy saving, increasing plant availability, shortening cycle times and thus increasing productivity and reducing costs are therefore the essential requirements which are now being placed on a modern galvanic or anodizing plant. An essential prerequisite for the best possible process implementation is that the power, required for the process, can be transferred to the goods carriers as loss free as possible. This makes the contacts mounted on the baths particularly important. Current transfer elements and electrical contacts are often responsible for both the generation of electrical power losses and standstill of the plants due to repair works. Contacts in electroplating plants are subject not only to high electrical but also to mechanical and chemical stress. Because even a sufficiently dimensioned bus-bar system alone does not provide a guarantee for a cost-effective and smooth operation of the plant by using insufficiently effective contact systems. Wrong cost-cutting Not least for reasons of cost, simple castings are used as contacts in electroplating plants, which neither correspond to the requirements of the plant either from their construction or from the electrical cross section. Contacts inside of electroplating plants, as already mentioned, are subject to high electrical, chemical and mechanical stress. Long-term operation requires the use of low transition resistors to ensure the current-dependent bath parameters and to avoid energy losses. Thus, for example, water cooling of contacts, that are often carried out, is not a cost-effective energy saving solution, since the heat/power losses generated here at the contact is dissipated with the cooling water. The aim is therefore to make contacts which allow the economical use of the energy and which are also suitable for a low-maintenance work inside of fully automatic driven plants.

Why offer so many different contact-systems It is simply because there are a lot of different plants and constructions in the market. It is therefore not possible to develop a contact series which is equally suitable for all systems or can be used anywhere. The shape, weight and design of the contact points of the goods carriers are extremely different. Thus, in addition to rectangular or H-shaped contact points, there are also profiles at the ends of the goods carriers. Also, there are extremely light or extremely heavy carriers, which all require a suitable designed and adapted contact....

The retraction itself is made possible by the weight of the goods rail/goods carrier. In order to protect the contacts from contamination and mechanical damage, they can be equipped with sturdy protective covers made out of stainless steel. An inexpensive system with a large spring travel for currents up to 5000 A is offered as standard. A system with a sturdy cast body and integrated guidance for currents up to 4000 A as well as a design for higher currents from 4000 A up to 14000 A Pneumatically driven contacts Optional as finger- or panel contacts In order to increase the contact...

The contact-fingers of the Titan system are operated by a special hydro-pneumatically activated force-booster. This new developed force-booster dissipates the incoming air pressure into a very high contact pressure by a hydraulic system. The installed hydraulic system is actuated with water and do not need any form of oil. So is by a leakage a contamination of the plating tanks absolutely impossible. All sealing elements are tested over a long period and are designed in compliance with the specific demands of the electroplating and anodizing industry. This unique system is deliverable for...
