Global adhesive manufacturer, tesa, is partnering with Vulkan Technic and Liebherr to advance the assembly line for electric vehicle (EV) battery packs. Previously, input from individual companies was necessary for bonding and assembling such battery packs.
Now, with an adhesive tape producer, a material manufacturer, and a general contractor working closely together, customers can get everything from a single source. The goal is to battery production is simplified by implementing an automated and tape-based solution.
The new adhesive tape, tesa ACXplus 76730 Box Seal, can be attached to battery packs with lids and those directly connected to the underbody of a vehicle. The tape does not require any curing times and can be applied easily and automatically without high demands on ambient temperature or humidity. Moreover, health and safety risks for users are minimized.
Next, the expertise of Liebherr and Vulkan Technic ensures that the technical requirements of the customers, including from a design, programming, production, and commissioning perspective.
The team presented customers with a first demo version.
“With the market launch of the new tesa ACXplus 76730 Box Seal, we not only wanted to bring an acrylic adhesive tape to the market that is characterized by strong performance and high flexibility, but also to offer a proper application concept,” said Boris Kawa, corporate marketing director — Automotive at tesa. “We then talked to our partner Vulkan Technic to set up first tests for such a concept.”
The interaction of an innovative adhesive solution and a fitting application also convinced Liebherr.
“When tesa introduced us to the innovative tesa ACXplus Box Seal, our interest was piqued,” said Viktor Bayrhof from Liebherr. “It promises a secure and automatable sealing of the battery pack, but at the same time also allows the battery pack cover to be dismantled for rework in the factory. This streamlines the production process because individual intermediate inspection testing can be replaced by a later end-of-line-testing, where the cover can be opened non-destructively. This is also interesting for the remanufacturing and recycling process of battery systems.”
