Frequently Asked Questions

Clear answers regarding file formats, turnaround times, quality assurance, and international trade terms.

We accept 3D CAD models in STEP (.step, .stp), IGES (.igs), Parasolid (.x_t), and SolidWorks (.sldprt) formats. For dimensional tolerances, thread callouts, and critical surface finish notes, please also provide a 2D drawing in PDF or DWG format.

For standard CNC machining and sheet metal inquiries, our application engineering team provides an itemized quotation and DFM manufacturability analysis within 2 business hours. Complex die casting tooling or multi-part assemblies are quoted within 12 to 24 hours.

Yes. We routinely execute bilateral Non-Disclosure Agreements (NDAs) prior to receiving customer files. You may provide your company’s standard legal NDA, or we can provide our mutual NDA document. All CAD files are stored on secure internal servers with restricted access.

We have no minimum order quantity for CNC machined parts; we frequently produce 1-piece prototype validation runs. For die casting and progressive sheet metal stamping, production runs typically scale from 500 pieces to hundreds of thousands of units.

We accept bank telegraphic transfer (T/T), Letter of Credit (L/C at sight), and credit card payments for initial prototypes. For regular commercial accounts, we offer credit terms (Net 30) subject to credit review. We bill in USD ($), EUR (€), and GBP (£).

Yes. We manage international air express (DHL/FedEx), air freight, and ocean container shipments under DDP Incoterms 2020. Export clearance, international transit, customs duties, and final warehouse delivery are handled under a single invoice.
