It integrates the advantageous resources of its parent company to provide customers with a comprehensive solution integrating additive manufacturing product design, new material research and development, process optimization, hot isostatic pressing and heat treatment, parts processing, and finished product inspection.


Core competitiveness


Leading Material Capabilities
The development of special additively-manufactured (low crack sensitivity) high-performance new materials (featuring high strength, high temperature resistance, and low density) enhances users' competitiveness in improving equipment technical and tactical specifications. Among these, new materials such as Ti2AlNb, ZGH4251, ZGH438, and ZGH447 have filled the gap in material selection for high-temperature lightweight, medium-temperature high-strength, and high-temperature service environments, becoming key material choices for multiple priority projects. Additionally, there are domestically leading capabilities in master alloy production, powder manufacturing, hot isostatic pressing, testing and analysis, and hardware support.

Professional Process Capabilities
With over 10 years of additive manufacturing experience and high-quality delivery of over 40,000 components, we have established technical specifications covering various materials including superalloys (such as GTD222, GH3170, GH3230, GH3536, GH3625, GH4099, GH4169, ZGH438, ZGH447, ZGH457, ZGH4251, MM509, GH5188, etc.), titanium alloys (e.g., TA15, TC4, Ti150, Ti2AlNb, etc.), stainless steels (316L, 304, etc.), mold steels (18Ni300, 17-4PH, 15-5PH, CX, etc.), and aluminum alloys (AlSi10Mg, AlSi7Mg, AlMgScZr, AlMnScZr, etc.). We possess professional capabilities in simulation, process modeling, microstructure control, microcrack management, and residual stress management, as well as the ability to handle surface, internal cavities, and internal flow channels. Furthermore, we are capable of precision additive manufacturing of oversized components with a maximum formable size of 1500mm×1500mm×1500mm and dimensional accuracy controlled within ±1mm.

Robust Talent Pool
Our core team boasts a 75% proportion of masters and doctorate degrees, with an average age of 34. It comprises over 10 additive manufacturing industry experts specializing in alloy composition design, forming processes, support structure design, machining, post-processing, testing, and other professional fields.

Stable Quality Control Capability
We have established a comprehensive quality system (such as AS 9100D, etc.) and reliable supply capabilities. With years of experience in delivering high-end additive manufactured metal parts, we have received full recognition from our users!
