Lork Group Granted National Utility Model Patent for an Aviation Engine Blade Solidification Mold

(Zhengzhou, July 28, 2026) Recently, Henan Lork Special Steel Co., Ltd., a subsidiary of Lork Group, received a utility model patent certificate from the China National Intellectual Property Administration. The patent is titled "A Solidification Mold for Aero-engine Blades" (Patent No. ZL 2025 2 1293687.2), with an authorization announcement date of May 26, 2026. Securing this patent further enriches the Group's technical capabilities in the manufacturing of critical aero-engine components.

This utility model patent relates to the field of aero-engine blade casting technology, specifically providing a mold structure design tailored to the blade solidification and forming process. As core hot-section components of the propulsion system, the casting quality of aero-engine blades directly impacts engine performance and operational safety. During precision casting, the design of the solidification mold plays a decisive role in determining the density of the blade's microstructure, dimensional accuracy, and the control of internal defects.

The patented technical solution focuses on optimizing the structure of the solidification mold. It aims to address issues found in existing technologies—such as uneven temperature field distribution and inadequate feeding efficiency during the blade solidification process—thereby enhancing process stability and the final product yield through rational mold structure design.

Mr. Jin, a representative from the Lork Group’s technology center, stated that the Group will continue to focus on tackling key technical challenges in high-end application sectors—such as aero-engines, biomedical implants, and semiconductor manufacturing. Centered on the material preparation and precision forming of specialty steels and high-temperature alloys, the Group aims to build a highly competitive patent portfolio and establish robust technological barriers. Moving forward, the Group will continue to leverage its foundational digital ecosystem—comprising "standards hubs," "digital platforms," ​​and "scenario-based think tanks"—to provide customers with systematic solutions spanning everything from materials to manufacturing processes.
