A Qingdao manufacturer built around precision metal forming
Sujie Hardware was established in 2010 in Qingdao, China. We produce precision springs, stamping parts, custom wire forms and hardware parts for industrial and OEM buyers, running continuous-die stamping, CNC spring forming, and precision grinding at the Qingdao production facility. Projects are reviewed from customer drawings, samples, or reference parts, and every order moves through in-process inspection before it ships.
Four core product categories
Precision Springs
Compression, extension and torsion springs formed and ground to confirmed drawing requirements.
Stamping Parts
Continuous-die and progressive stamped metal components produced to confirmed order requirements.
Custom Wire Forms
Bent and formed wire components engineered to customer drawings, from simple hooks to multi-bend assemblies.
Hardware Parts
Fasteners, brackets, buckles and rigging hardware manufactured to support assembly and logistics applications.
From coil and wire to finished, inspected parts
Continuous-Die Stamping
Blanking, forming and piercing combined in a single progressive-die pass for consistent output.
Spring Forming
CNC multi-axis coiling and forming machines produce compression, extension and torsion springs.
Precision Grinding
Ground ends and critical surfaces are processed to the confirmed drawing requirements.
In-Process Inspection
Dimensional checks at setup and throughout the run confirm parts stay within drawing tolerance.
