Technology & Products

Key Products

AFS-J1600Pro (3DP sand printing equipment); AFS-500 (SLS wax mold printer); BJ binder jet metal printers; SLS selective laser sintering systems; SLM selective laser melting systems; DED directed energy deposition systems

Technological Advantage

Proprietary binder jetting process achieves high-density degreasing and sintering for metal/ceramic parts, with performance exceeding MIM international standards; large-format sand printing (e.g., 4-meter 3DP sand printer) enables direct production of massive casting molds.

Patent position

Longyuan Forming filed 7 patent families in 2022-2024, down 78% from 32 in 2019-2021, while tracked AM filings in the same patent offices rose 9%. AMPulse analysis

Differentiation

Value Proposition

Reduces lead times for complex castings from months to days using 3DP sand printing, enabling on-demand production of engine blocks, cylinder heads, and other large components with 40-60% faster turnaround.

How They Differentiate

Offers integrated hardware and nationwide rapid manufacturing services, unlike pure equipment vendors; 3DP sand printing systems (e.g., AFS-J1600Pro) provide larger build volumes and faster casting mold production than many competitors; over 30 years of industry experience in China with early-mover advantage.

Market & Competition

Target Customers

Foundries, automotive manufacturers, aerospace companies, and industrial manufacturers requiring rapid prototyping and production.

Industry Verticals
