About YB

Custom Iron Casting Supplier with Engineering Oversight

YB Metal is a custom iron casting supplier based in China, serving OEMs across the globe. We help industrial and agricultural equipment manufacturers source grey and ductile iron castings, complete with CNC machining, heat treatment, inspection, and export-ready packaging.

Unlike typical trading companies, we offer full engineering control, on-site quality checks, and clear bilingual communication. Our role is to bridge global buyers with reliable foundries and machining partners in China — managing the entire process from drawings to delivery.

Built on Machining, Evolved Through Casting

Founded in 1991, our parent company FUSHUN started as a precision machining service provider. Over time, we became the preferred machining partner for local foundries — handling machined iron castings for industrial use.

To meet growing international demand for complete casting solutions, we launched the YB Metal brand, focused on custom iron castings, small batch production, and turnkey sourcing management..
