Huayinsheng is a one-stop OEM manufacturing factory specializing in custom zinc and aluminum die casting parts and precision CNC machining. We mainly serve brand owners, product design companies, manufacturers, and assemblers, providing complete manufacturing services from mold design and tooling to die casting, CNC machining, surface finishing, and assembly.

Unlike ordinary contract processing factories, Huayinsheng places greater focus on early-stage engineering review and manufacturability optimization, helping customers reduce development risks before tooling and improve consistency and delivery reliability in mass production.

We are especially experienced in small-to-medium, mid-to-high-end appearance parts and functional structural components, widely used in smart home, consumer electronics, beauty and personal care, automotive accessories, and luggage hardware.

With production bases in both China and Vietnam, an integrated manufacturing workflow, and strict quality control systems, Huayinsheng is committed to providing overseas customers with more efficient, stable, and reliable custom manufacturing services.
