Monolithic helical rotor geometry: Atlas CopcoRecent Research Landscape

Structural integrity and balance are compromised by multi-part assembly in screw compressors, leading to mechanical failure and high finishing costs. This engineering approach utilizes integral core casting to control internal cavity topology and eliminate assembly interfaces.

What technical problems is Atlas Copco addressing in Monolithic helical rotor geometry?

Casting surface finish irregularities

(4)evidences

Post-casting surface roughness and geometric inaccuracies in complex helical geometries necessitate extensive secondary machining. Reducing these defects minimizes manufacturing time and ensures structural integrity of the rotor.

Excessive component structural mass

(3)evidences

Traditional manufacturing of complex housing structures results in high material consumption and unnecessary mass. Reducing weight and waste improves resource efficiency and handling ergonomics in industrial equipment.
