ZETKA transforms proven methods in combination with innovative ideas
ZETKA has been providing support to its customers with prototypes and small series right from the very first electrically powered vehicles. The experience we have gained gives us a knowledge advantage and enables us to ask the right questions to accurately determine customer needs and act accordingly.
Using lean tools on our Bihler GRM-NC systems enables us to produce busbars with a material thickness of up to 4 mm, depending on the component size, cost-effectively and with minimal material consumption. We generally optimise the geometry with our customers in order to achieve the highest possible process reliability.
More complex busbars, on the other hand, are manufactured using modular progressive tools on our automatic punching machines. Using both production concepts, we are able to produce both small series starting at 50,000 pieces and large series with several million parts. We use prototypes and pre-series that have been cut by laser or micro water jet in the development process.
Finishing work with press-in threaded bolts and press-in nuts as well as the use of insulating foils or hoses is usually carried out in a subsequent operation, separately from the punching process. This also allows us to carry out mechanical and electroplating post-treatment.
We agree the most cost-effective form of packaging as bulk goods with our customers during the quotation phase. For optimised further processing, we use product-specific blister packaging on request or, as long as the material thickness allows, we deliver the parts as strip-fed goods.
The materials used are sourced exclusively from European factories. If necessary or requested, we pre-finish the material or the individual parts are finished using frame electroplating.
Everything powered by electricity needs a battery and must be charged. ZETKA provides the necessary individual components or pre-mounted assemblies for these. Depending on the application, we combine several materials using joining technology or welding processes. These materials are usually aluminium alloys and copper alloys. The use of laser-welded bimetallic strips is often a cost-effective alternative. Our BIZON press-in contacts are the ideal solution for contact systems in battery management and cell contacting.
The biggest challenge for e-mobility is a functioning private and public private charging infrastructure. The network of filling stations will continue to be needed, but charging parks, charging stations at supermarkets and in car parks, and wall boxes in private homes and apartments are the necessary prerequisites to ensure the transition to e-mobility. We are also supporting our customers in this area with classic stamped parts, but also with innovative assemblies that are characterised by their durability and reliability.
