Frequently Asked Questions

Direct Answers Before You Request a Quote

These answers cover the questions buyers and engineers most often ask when starting a custom manufacturing project.

What files should I send for quotation?

Send the 2D drawing and 3D model whenever available. Include material, finish, quantities, critical
tolerances, required documentation and delivery destination.

Yes. Prototype quantities can start from one piece, subject to part geometry, material and process review.

We support prototypes, low-volume orders and repeat production. Final capacity and delivery are
confirmed for the specific part and quantity.

Simple samples may be completed in approximately one week, while regular orders are commonly
planned around 10-15 days. Actual lead time depends on material, complexity, quantity, finish, inspection
and current capacity.

Tight-tolerance features are reviewed according to material, geometry, feature access, process stability
and inspection method.

Yes, when requested and confirmed before production. Documentation scope should be stated during
quotation.

Customer drawings and project information are used for quotation and manufacturing review. NDA
requirements can be identified when submitting the RFQ.

Ready to Move from Research to a Real Quotation?

Send your drawings, models and available project requirements. Tianyida will review the component and respond with the appropriate manufacturing approach, technical questions and quotation. You do not need every field completed before contacting us. Submit the available information, and our team will help identify what still needs to be confirmed.

Please attach your 2D CAD drawings and 3D CAD models in any format including STEP, IGES, DWG, PDF, STL, etc. If you have multiple files, compress them into a ZIP or RAR. Alternatively, send your RFQ by email to eric@yd-proto.com.
