Smart Manufacturing Technology (Head office: Nottingham, UK, CEO: Pramod Mooneeramsing) announced on June 30, 2025 that it has established a strategic partnership with Prometech Software Inc. (Head office: Bunkyo-ku, Tokyo, President and CEO: Takahiko Suzuki).

We have agreed to strengthen the collaboration between Smart Manufacturing Technology’s gear system and motor analysis software MASTA and Prometech Software’s particle method CFD analysis software Particleworks to provide innovative solutions to both companies’ customers around the world.
The innovation of electric powertrains is progressing toward higher speeds and higher power. In that respect, we are convinced that there is great synergy between gear analysis and fluid analysis, such as lubrication of gear systems, minimizing churning losses, and efficient cooling of electric motors. This will significantly improve development efficiency, shorten the time to market, and save cost.
The two companies will cooperate on software integration and interfaces in the development of technology and products using gear systems and fluid analysis.
Paul Langlois, CTO of Smart Manufacturing Technology, says,
“MASTA covers all aspects of the design and analysis process for transmissions and electrified powertrains from durability to NVH and efficiency. Sometimes there arises the need for further high-fidelity analyses of lubrication supply, churning losses and cooling. By coupling with Particleworks the process for these analyses can be greatly improved, saving our customers time and money.”
Takahiro Suzuki, CEO of Prometech Software, says,
“I am delighted to announce our strategic partnership with Smart Manufacturing Technology. The integration of MASTA, their world-class gear system analysis software, with our fluid dynamics software, Particleworks, creates a powerful synergy for advanced lubrication and cooling design in electrified powertrains. Through this collaboration, we will empower our customers in their product development and together, lead the technological innovations that will shape the future of mobility.”
