Episode 311 - Inkjet meets e-mobility: WeldTone and Inkatronic bring precision insulation to EV production

In this FuturePrint Podcast episode, we speak with Rainer Stricker (WeldTone) and Mikael Boedler (Inkatronic) about a fast-emerging application for industrial inkjet: UV insulation coatings for EV battery and electronics components.

Rainer explains Weldtone’s background in functional adhesives and insulation coatings, and why the next generation of EV architectures (including cell-to-pack and cell-to-chassis) is increasing the performance requirements placed on insulation layers - especially as insulation must coexist with high-strength structural bonding processes.

Mikael shares how Inkatronic’s application centre model - combining in-house engineering, CNC capability, automation and PLC programming - enables rapid iteration and upscaling trials. Together, Weldtone and Inkatronic are developing inkjet-based insulation processes that deliver selective deposition, tight thickness control, and fast UV curing.

The discussion compares inkjet with traditional insulation approaches such as PET film wrapping, powder coating, and spray coating. Inkjet’s key advantage is its digital selectivity: coating only where needed, reducing waste and post-processing, and enabling reliable insulation on more complex 3D-shaped parts (connectors, housings, cooling elements), not just flat surfaces or simple geometries.

Both guests also address adoption dynamics: mass production is already underway in China for certain applications, while Europe is in a rapid evaluation phase - with the main bottleneck being access to validated demonstration equipment for sample generation, qualification, and process-window development.

Rainer and Mikael will present and demonstrate the process at FuturePrint Industrial Print, Motorworld Munich, 21-22 January, including live printing and curing on representative 3D customer parts.
