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.
