Technology & Products
Key Products
Castings for high-end equipment, with marine and shipbuilding castings as a core line. The company also machines and assembles castings and produces 3D-printed sand molds and cores for casting. A horizontal flaskless molding line was in use by 2022, and a Phase II upgrade added the 3D printing line and an automated storage warehouse.
Technical position · AMPulse analysis
The company holds national 'Specialized, Refined, Distinctive and Innovative' (专精特新) Little Giant status. It prints sand molds and cores in-house, which removes the need for tooling, and it has an established base of export customers. Phase II was expected to raise annual output from about 5,000 t to about 6,500 t.
Differentiation
Value Proposition
Printing sand molds and cores directly from 3D models removes pattern and tooling work. The company reports that this cuts new-product mold lead time from one to two months to as little as one day, and that the sand can be recycled.
How They Differentiate
Haigong is a casting producer that uses sand 3D printing internally, rather than a printer OEM. It focuses on marine and heavy-equipment castings for European export customers.
