What We Need From You
You don't need perfect drawings or finalized designs to begin. Here are three ways to start your project with us.
You Have Drawings
If you have CAD files or technical drawings, you're ready for a detailed quote. Upload your files and we'll review them within 24 hours.
- 3D: STEP, IGES, STP, SLDPRT
- 2D: DWG, DXF, PDF
- Include tolerances & material specs
You Have a Sample
Have an existing part you want to replicate or improve? Send us a sample and we'll reverse-engineer it with precision measurements.
- Competitor parts to match
- Worn parts to reproduce
- Legacy parts with no drawings
You Have an Idea
Even rough sketches or verbal descriptions are enough to start. Our engineering team can help develop your concept into manufacturable designs.
- Hand sketches or photos
- Reference products or images
- Performance requirements
Not sure which option fits your situation?
No problem. Contact us with whatever you have and we'll guide you from there. Every project is different, and we've helped hundreds of customers go from concept to finished parts.

How we protect and deliver your parts globally
Q: What information do I need to get a quote?
A: At minimum, we need to understand what you want to make: drawings, a sample, or even a concept description. The more detail you provide — materials, quantities, tolerances, finishes — the more accurate your quote will be. But don’t wait until everything is perfect. We can help fill in the gaps.
Q: How quickly can I expect a quote?
A: Standard quotes are delivered within 24 hours of receiving your files. Complex projects with multiple parts or special requirements may take 2-3 days. Rush quotes are available if you need faster turnaround — just let us know.
Q: Do you offer design assistance?
A: Yes. Our engineering team can help develop concepts into production-ready designs, optimize existing drawings for manufacturability, or reverse-engineer samples into CAD files. Design support is often included in the quotation process at no extra charge for production projects.
Q: What file formats do you accept?
A: For 3D models: STEP, IGES, STP, X_T, Parasolid, SLDPRT, and most major CAD formats. For 2D drawings: DWG, DXF, and PDF. If you have a format not listed, send it anyway — we can usually work with it.
Q: Can I visit the factory?
A: Yes, and we encourage it. Factory visits can be arranged for qualified customers. We’ll coordinate your visit, arrange transportation from Guangzhou airport, and provide a comprehensive facility tour. Many customers combine factory visits with a quality audit before starting production.
Q: How do you protect my intellectual property?
A: We take IP protection seriously. We sign Non-Disclosure Agreements (NDAs) upon request before reviewing any project details. Your designs and tooling are your property. We never share customer designs, use them for other customers, or sell parts to third parties without explicit authorization.
Q: What quality certifications do you hold?
A: We maintain ISO 9001:2015 certification for our quality management system and IATF 16949 certification for automotive quality standards. We also comply with RoHS environmental requirements and can provide material certifications, inspection reports, and full traceability documentation.
Q: What happens if parts don't meet specifications?
A: If any parts don’t conform to the agreed specifications, we make it right at no cost to you. Depending on the situation, this may mean producing replacement parts, issuing a credit, or expediting a new shipment. We aim to resolve quality issues within 48 hours of notification.
Q: Are tooling costs separate from part costs?
A: Yes, tooling is quoted separately and remains your property. For simple sheet metal parts, tooling may be minimal or included. For stamping dies, molds, or complex fixtures, tooling is a one-time investment that we amortize or quote separately. All tooling costs are clearly itemized in your quote.
Q: Do you handle international shipping?
A: Yes. We ship globally via air freight (DHL, FedEx, UPS) or sea freight depending on your timeline and cost preferences. We prepare all export documentation, commercial invoices, packing lists, and can provide customs paperwork for most destinations.
