On August 11, 2026, Hangzhou Heyi Aerospace Technology Co., Ltd. disclosed its angel round fundraising plan via 36Kr, aiming to raise RMB 20 million at a post-investment valuation of RMB 200 million. The company positions itself as a full-chain metal additive manufacturing service provider for the commercial aerospace sector, employing a three-in-one model of "new material R&D + upfront DfAM design + engineering-grade quality system," covering the complete closed loop from materials and design to mass production and delivery. Key technical highlights include AI-driven design of new alloy compositions, industrializable results such as a 400°C heat-resistant aluminum alloy and high-strength aluminum matrix composites, and DfAM methods like topology optimization, integrated configuration, and conformal cooling. On the quality front, the company has secured GJB 9000C military standard certification, ISO triple-system certification, and a second-level confidentiality qualification. Commercial aerospace is one of the fastest-growing downstream applications for metal powder additive manufacturing (e.g., rocket engines, satellite structural components). Heyi Aerospace's full-chain "material R&D + design + manufacturing" model means its powder selection and process parameters will directly influence upstream powder supplier choices. Value for powder buyers: ① 400°C-grade aluminum alloy powder is a domestic gap—traditional aluminum alloys suffer severe high-temperature strength degradation, making heat-resistant aluminum alloys a critical need for commercial aerospace; ② Heyi Aerospace's powder selection will reshape the upstream supplier landscape—watch its subsequent material certifications and supplier screening; ③ The commercial aerospace track demands extremely high powder quality and batch-to-batch consistency (military-grade), giving qualified powder suppliers a greater opportunity.
