We are a direct manufacturer with our own production workshop and QC team, so you get factory prices and consistent quality control without a middleman.

Please share the part number, machine model, drawings (PDF/STEP/DWG) or clear photos with dimensions, required material, surface treatment, order quantity and destination port. For standard parts, the OEM number or sample is usually enough.

We can provide ISO 9001, material certificates (MTC), heat treatment reports, dimensional reports and third-party inspection reports such as SGS or BV if required.

Stock items ship within 1 to 5 days. Standard production takes around 7 to 15 days. Custom or large orders usually take 20 to 35 days depending on process and quantity. Urgent orders can be prioritized on request.

We work under ISO 9001 and inspect every stage: incoming material check, first-piece inspection, in-process sampling and 100% final inspection before shipment. Material test certificates and inspection reports are available on request.
