Engineered for high sphericity, low oxygen inclusion, and superior powder rheology across laser powder bed fusion (LPBF), direct energy deposition (DED), and metal injection molding.
Advanced 3D printing technologies are transitioning from rapid prototyping to distributed, series-scale production. Global manufacturers require material stability, high repeatability, and strict chemistry control.
Global original equipment manufacturers (OEMs) demand dual-sourcing reliability and guaranteed batch uniformity. With our integration into the Toyo Aluminium K.K. Group since 2009, we ensure consistent multi-continental supply backed by Japanese process discipline.
The latest LPBF systems utilize high-speed multi-laser arrays that require optimal flow rate and high apparent density. Our closed-loop ultrasonic sieving and inert gas classification eliminate satellite particles, preventing micro-porosity defects in sintered layers.
Additive manufacturing produces near-net-shape components with a buy-to-fly ratio close to 1:1, drastically reducing scrap versus conventional CNC subtractive machining. Our clean atomization process is ISO 14001:2015 certified, lowering lifecycle carbon footprints.
