A precision metal forming manufacturer based in Qingdao, China
Established in 2010, we manufacture precision springs, stamping parts, custom wire forms and hardware parts in Qingdao, China.
Built on the press floor, not in a showroom
Sujie Hardware was founded in 2010 in Qingdao, China. The supplied equipment record covers continuous-die stamping, precision grinding and CNC wire forming across four core product lines: precision springs, stamping parts, custom wire forms, and hardware parts.
Buyers can send a drawing, a sample part, or a reference photo. Each project is reviewed for feasibility and tooling where needed, then proceeds through sampling, in-process inspection, and shipment. We do not publish prices online — every project is engineered and quoted based on material, tolerance, volume and finishing requirements.
How we work with OEM buyers
Manufacturing Discipline
Orders move through confirmed tooling, forming and inspection steps at the Qingdao production facility.
Drawing-Led Engineering
Our process starts with the customer drawing or reference sample. Tooling and process plans are built to match the specification, not the other way around.
Direct Communication
Sourcing inquiries are reviewed directly against the supplied drawing, sample or reference part.
Order-Specific Inspection
Inspection requirements and available reports are confirmed for each project before production.
