FREQUENTLY ASKED QUESTIONS

Pre-Order & RFQ FAQs

Essential answers regarding drawings, tolerances, confidentiality, and workflows.

Can I request a consultation before having complete 3D drawings?

Yes. You can provide rough dimensions, reference images, intended application, and estimated quantity. We will help review manufacturability, though final pricing and production feasibility will require 3D CAD files (STEP/STP) and 2D engineering drawings.

Which drawing formats and files are needed for quotation?

We recommend 3D files in STEP, STP, or IGES format, accompanied by 2D drawings (PDF) detailing critical tolerances, threads, and surface finishes. Please include material, color, quantity, and delivery target. Larger assemblies can be provided via accessible cloud download links.

How do you safeguard confidential and proprietary designs?

We prioritize intellectual property protection. We are glad to sign a mutual Non-Disclosure Agreement (NDA) before you share sensitive CAD files. For preliminary inquiries, you can also omit proprietary features and focus on dimensions and material specifications.

Where can I learn more about CNC machining, vacuum casting, and finishing?

Explore our dedicated service pages: CNC Prototype & Parts Machining, Silicone Vacuum Casting, and Surface Treatment & Finishing. If you are uncertain of the best process, let us know your part's mechanical criteria and volume.

How do I check order status or provide quality feedback on existing orders?

Select "Existing Order & Quality Feedback" in the inquiry form, or email us directly with your PO number or project reference. If reporting a dimensional, fit, or cosmetic concern, kindly attach photos, inspection reports, and drawing revisions so our quality team can inspect and assist immediately.

Can I schedule a factory tour or ship sample parts?

Yes, factory visits and technical meetings are warmly welcome. Please reach out in advance to confirm visiting dates or logistics. Our address is Room 801, No. 10 Min'er Road, Chang'an Town, Dongguan, China. You can also explore our plant anytime via the 360° Virtual Tour link.
