Your drawing.
Our next conversation.
Tell us what you need for your custom precision mold components. Share what is ready; we can clarify the rest together.
01 / SEND THE CURRENT REVISION
A dimensioned PDF and a matching 3D model help us review the part. Package CAD files together in a ZIP.
02 / ADD ONLY WHAT IS MISSING
There is no need to repeat the material, tolerances or finish already on your drawing. Note any exceptions or open questions.
03 / SET THE SCOPE
Give a quantity per part, or select “To be confirmed.” Pricing and lead time follow a review of the agreed requirements.

BEHIND YOUR INQUIRY
People who understand
the part behind the drawing.
A mold component moves through several connected operations. Share the part’s function and assembly requirements so the discussion can cover machining access, EDM features, grinding allowances and the inspection plan.

Precision grinding · operator and equipment

Discuss your manufacturing route
For complex mold inserts, core pins and custom mold parts, include small radii, deep features, thin walls and surface requirements in your inquiry. These details help the team review a suitable combination of CNC machining, EDM and finishing operations.

PRACTICAL ANSWERS
Before you send
your inquiry.
Preparing the right information makes a precision mold component discussion more useful. Browse these answers, or email us with your specific question.

AI-generated technical illustration. For RFQ preparation only; not a customer drawing or manufacturing specification.
Which files should I include in a mold component RFQ?
Include a dimensioned 2D drawing and matching 3D model where possible. Upload PDF or ZIP files, up to 3 files and 20 MB per file. Package STEP / STP, IGES / IGS and DWG files inside a ZIP. Include the drawing revision and highlight critical dimensions. If your file is too large, email the team to arrange an appropriate way to share it.
Can I discuss CNC machining, EDM or precision grinding?
Yes. Describe the part geometry, material and intended function. Include tight tolerances, deep cavities, small internal radii or surface finish requirements so the team can discuss the manufacturing route and the information needed for a quote.
What if my drawing is not final yet?
Send the information currently available and clearly mark the design as preliminary. Tell us which features are still being reviewed. The team can discuss technical questions; pricing and timing need to be confirmed against an agreed drawing and scope.
Can confidentiality be arranged before sharing drawings?
Contact the team before uploading confidential files and mention your NDA requirements. Arrange and confirm confidentiality terms before sending information that requires an agreement.
How are delivery timing and inspection requirements agreed?
Include your target delivery date, required quantity and any inspection reports or acceptance criteria. Lead time and the inspection scope are reviewed with the component requirements and confirmed during the quotation discussion.
Can I arrange a factory visit in Dongguan?
Email or call with your preferred dates, number of visitors and purpose of the visit. Please wait for confirmation before making travel arrangements. Our factory address and map link are at the top of this page.
