KVE and PinettePEI Partner to Provide Induction Welding Integrated Solutions for Thermoplastic Composite Parts

This collaboration stems from a shared vision between both parties to promote high-rate and sustainable manufacturing of aerospace structural TPC components. KVE and Pinette PEI will jointly launch an integrated solution encompassing TPC stamp forming and induction welding assembly. This technology is expected to overcome current component size limitations, reduce weight, shorten production cycles, enhance recyclability, and lower overall costs. Previously, PEI has supplied TPC production equipment to clients such as Airbus's Bremen plant.

In the latest technology validation, the induction welding process jointly developed by KVE and Pinette PEI was successfully applied to the production of an aerospace-grade torsion box demonstrator. As a key load-bearing component connecting the wing and fuselage, this structural part marks a breakthrough in the application of thermoplastic composites in large primary load-bearing structures.

The use of fully automatic induction welding technology has achieved the integrated forming of ultra-large TPC torque boxes, reducing weight by 40% compared to traditional metal structures. The weld strength reaches more than 95% of the base material, and the production cycle is shortened by 60%, verifying that this technology meets the high-cadence mass production requirements of the aerospace industry. The demonstration piece has passed static load and fatigue tests under European Aviation Safety Agency (EASA) standards and is expected to enter the airworthiness certification stage in 2026. This achievement provides a new process path for the development of composite material wings for the next generation of single-aisle passenger aircraft.

Erick Rousseau, CEO of Pinette PEI, stated: "The partnership with KVE is a natural strategic choice that will create multiple values for our customers. Through this collaboration, customers will benefit from a highly integrated and automated end-to-end solution covering material pretreatment, stamping, welding, and non-destructive testing (NDT)."

According to the division of labor, Pinette PEI will be responsible for the design and manufacturing of system units, while KVE will continue to provide specialized welding hardware, software, and components, and support customers in developing welding processes with its expertise. To accelerate technology promotion, the welding system will be deployed on Pinette PEI's TIFAANI production line for multi-process R&D testing of TPC.
