Motionwell has delivered 5-axis CNC shot peening machines for turbine blade surface treatment, a process that improves fatigue life by 30-50% through controlled compressive stress layers. We also participated in the Aerospace Open Innovation Challenge (AOIC) 2024 with A*STAR SIMTech, developing force-controlled robotic grinding solutions for CFRP composite panels and nacelle paint removal. We serve aerospace OEMs and engine MRO services providers across the region.
For high-reliability industries, the focus is consistent performance, validated measurement, and build quality that stands up to audit. We design systems where every parameter is traceable, every process step is repeatable, and every result is documented.
