Ningbo International Metal and Metallurgical Industry Expo is an annual trade show for the metal and metallurgy industry, held in Ningbo, Zhejiang. It is built around four themed zones — foundry, forging and die casting; fasteners, springs and bearings; motors and magnetic materials; and powder metallurgy, hard alloys and advanced ceramics — and serves the manufacturing base of Ningbo and the wider Yangtze River Delta.

The show gathers equipment and tooling for casting, forging and die casting, together with automation controls, surface treatment, heat treatment and industrial furnaces. It also covers laser, welding and sheet-metal machinery; fastener, spring and bearing production lines and finished parts; hydraulic, pneumatic and sealing components; sheet, strip, bar, wire and metallurgical automation; copper, steel and non-ferrous metal processing; valves and fluid technology; and powder metallurgy with its materials, equipment and testing instruments.
