Technology & Products
Key Products
Metal 3D printing services for liquid rocket engine components (injectors, combustion chambers, nozzles, expansion sections, turbine pumps); aviation engine blades; large-format metal 3D printing (up to 1m+ diameter parts); full-process service chain (design to SLM printing to heat treatment to CNC machining to inspection)
Technological Advantage
Large-format SLM metal 3D printing capability (parts up to 1m+ diameter); proprietary 3D printing path algorithm and laser energy field distribution models; full-process in-house capabilities (design, printing, heat treatment, machining, inspection); 30+ patents; GJB9100C military aerospace quality certification
Differentiation
Value Proposition
Provides end-to-end metal 3D printing solutions (design, printing, heat treatment, machining, inspection) for aerospace-grade liquid rocket engine components, serving China's commercial space sector
How They Differentiate
Unlike BLT and Farsoon which are primarily equipment manufacturers, Sinsun is a pure service bureau focused specifically on aerospace engine components. It specializes in large-format parts (1m+ diameter) for liquid rocket engines — a niche that requires deep domain expertise in rocket engine design and thermal management, not just printing capability.

Target Customers
Commercial aerospace companies (liquid rocket engine manufacturers), aviation engine manufacturers, defense contractors, and industrial manufacturing enterprises
Industry Verticals
Aerospace/Defense; Commercial Space; Aviation; Marine; Nuclear; Automotive; Education
Competitors
Bright Laser Technologies (铂力特, BLT); Farsoon Technologies (华曙高科); Xi'an Bright Additive Manufacturing
