Pressure Vessels
Our breakthrough Magnetic Pulse Welding (MPW) technology makes it possible to bind materials at a molecular level and at room temperature, without fumes or filler material, preserving the material’s initial properties.
Increasingly efficient and reliable, our industrial, turnkey MPW systems are currently being used by automotive industry leaders for mass production of key components of highly efficient HVAC (Heat Ventilation & Air Conditioning) systems utilized in electric vehicles, like R744 (CO₂) accumulators and R290 (Propane) receiver driers.
We enable our customers to save material, resulting in weight and cost savings, while ensuring high levels of product performance.

Working together
Over the past 10 years we have developed the most powerful and accurate 3D computational models that allow us to simulate and predict the welding window of the Magnetic Pulse Welding process, happening in few millionths of a second.
Co-engineering through simulation can be applied for fast prototyping. This phase is also of paramount importance to freeze part geometry as well as the welding tools.
Once you have qualified the prototypes, your MPW System is manufactured by our team. Bmax standard procedure involves MPW System buy off or Factory Acceptance Tests (FAT) with your teams at the end of the testing period, at Bmax premises.
From installation to commissioning of your equipment and training of your teams, Bmax provides a turnkey solution to start up your system in the best conditions till the final acceptance.
Our dedicated maintenance team delivers best-in-class Services, as well as Spare Parts & Consumables to our Customers. We adapt our purposes to your specific needs and expectations thanks to flexible, comprehensive and tailor-made Service Level Agreements.
As for Maintenance, we offer a broad range of options, including remote maintenance and assistance, preventive and curative maintenance.
Our long-term technology roadmap enables our teams to provide you with systems featuring increased component lifetimes and reliability, optimized production cycle times, reduced maintenance and user-friendly operation.
Easily retrofittable, all improvements can be integrated in already installed systems, enhancing Overall Equipment Efficiency over time.
