Coexpair is specialized in the engineering and production of resin injection and curing machines for composite parts for the aerospace industry. For years, Coexpair has relied on the full drive and automation portfolio of Siemens for these machines.  With the creation of CoexpairDynamics in 2020, the Walloon organization branched out to fiber deposit automation, where narrow strips of carbon fiber are placed on molds before resin is added. "In doing so, today we control all facets of the production process line, from the lay-up of the carbon fiber on the molds to the de-molding of the finished composite parts," says Cédric De Roover, business unit manager at Coexpair Dynamics. "In addition, we differentiate ourselves in the industry by acting as an R&D partner for our customers, supporting them in the engineering of their parts and then developing and producing custom machinery for this."  With the support of the Walloon government, Coexpair Dynamics therefore developed a machine that should allow aircraft manufacturers to optimize their production of composite parts. The machine combines the precision of CNC control with Automated Fiber Placement  fromTrelleborg Sealing Solutions in Albany, New York, US, developed to lay narrow strips of carbon fiber on complex shapes. Herein lies the strength and uniqueness of Coexpair Dynamics' machine.

To handle the complex machining applications, Coexpair Dynamics chose the cutting edge SINUMERIK One CNC system from Siemens, now fully integrated in TIA Portal.  SINUMERIK One is the state-of-the-art control for high-end machining segments like aerospace  and offers maximum CNC machining performance, along with flexibility and openness. The promised advantages of digitalization are being implemented by Coexpair. Having removed the boundaries to large-format robotic fiber placement, expectations now rise toward making breakthrough improvements across the entire part production process by implementing Edge, IA and Virtual machining.
