AI-Powered supplier vetting

SummaryThe supplier presents itself as a manufacturing-oriented OEM partner specializing in metal processing and fastener-related products. Evidence shows CNC punching, bending, stamping, welding, assembly, laser cutting, tapping, riveting, cold heading, thread rolling, painting, and other equipment, along with documented inspection procedures. It reports customization from samples and designs and provides 3D software design services. Its stated qualified-supplier relationship with Mitsubishi Electric supports manufacturing experience, but no formal certification is identified. Export sales account for 41%–50%, with Shanghai Port as the stated nearest-port connection and peak-season lead time of one month. Overseas service infrastructure is limited: no overseas warehouse, showroom, agents, branches, or offline trade-show participation are reported. Manufacturing capacity relies on no valid contract with related subcontractors, and no in-stock capability is available. Financial data is not assessed because...

Product Q&A

Q:How can international buyers trust your delivery time and shipment?

We are located in Shanghai with efficient logistics. We provide promised delivery dates (7-10 days for samples, 20-30 days for bulk) and send regular on-site photos and videos during production

Q:Do you accept small volume orders?

Yes, we are very flexible. We serve single prototypes, small batches of 100 pieces, and large-scale mass production with the same rigorous attitude.

Q:What format of drawings should I provide for an accurate quotation?

We recommend 3D files (STEP, IGS, SolidWorks) for weight calculation and 2D drawings (PDF, DWG, DXF) for tolerances. Physical samples are also acceptable if drawings are unavailable.

Q:Why is it important to provide 3D files during the quotation stage?

3D files help the engineering team accurately calculate material weight and simulate bending/unfolding, ensuring a more precise quotation.

Q:What is the main role of 2D drawings in production?

2D drawings serve as the legal basis for marking tolerance requirements, surface treatment instructions, and thread specifications to ensure manufacturing accuracy.
