Research & Development


Our founder, Lievin Dedecker, had the innovative idea to convert metal gears towards injection molded parts back in 1950 to reduce NVH effects in transmissions. 7 decades later SUB-ALLIANCE has developed extensive research & development capabilities to commit to this original technology approach, enhancing global performance of our customer’s most demanding applications. Nowadays, our R&D team is focused on advanced composite material (PEEK, carbon fiber, lightweight cost-effective solutions, out of autoclave technologies…), new materials for the most demanding thermal managing applications (alloys produced by metal, ceramic and powder injection molding), multi-physic and multi-material product simulations (anisotropic material properties) and transmissions optimizations and simulations. With our approach, we’re able to produce the lightest products with extremely durable properties.



  • New materials composed of advanced alloys for thermal managing applications 
  • Increase production rate, decrease production cost and weight of composite parts  
  • Optimizations of transmissions and gears by Finite Element Simulations







  • Lightweight thermoplastic composites components for aircraft (weight, cost and CO2 reduction)
  • High-thermal composites for LEAP Aircraft engines
  • Transmissions for E-Drive (electrical) autonomous vehicles
  • High-torque differential for competition vehicles




Our global approach combining technology, cost-effective solutions with the highest quality and best delivery times is key to establish a long-term relation with our customers. Our complete team, from management, skilled engineers to dedicated operators, will help you towards successful business in the most reliable way.





Aided with the best-in-class software, our development team is open to discuss your application with a design to cost approach. We’ll be able to decrease weight, cost and increase production rates.  We know our processes and are able to predict the complex product behavior.





SUB-ALLIANCE and our affiliated companies are fully integrated in the value-chain of advanced products from our customers. By enabling the highest quality standards in the market, our factories are able to produce the required quality within short lead times and budget. The different plants have standard quality labels as EN9100 or Aerospace and Defense related certifications as EN9100 / AS9100. Our companies work within a charter describing strict working procedures for the following domains: Environmental and working conditions ethics and security.








We won’t be able to engineer a complete aircraft, wind turbine nor excavator, but SUB-ALLIANCE gathers enormous knowledge on how to develop and manufacture advanced sub-systems and components. With our Co-Engineering approach, we share our expertise and enable to develop lighter, more robust and cost-effective products.
