Buyer RFQ resource

Prepare a clearer RFQ for custom cast and machined parts.

Use the information already available—a drawing, model, sample, worn part, or photographs—to organize an initial manufacturing review. The tool identifies missing inputs without blocking contact or making technical assumptions.

Information organizer

Build an RFQ summary from what you know now.

This is not an automatic quotation. It helps purchasing and engineering teams separate available facts from points that still need manual clarification.

1. What part evidence is available?

Choose every item you can share. One useful source is enough to start organizing the review.

Open buyer files

Use the checklist inside your purchasing workflow.

Both files are open downloads. The PDF works as a printable one-page prompt; the workbook gives purchasing and engineering teams an editable project record.

Buyer guide

Separate what starts a review from what controls production.

A useful first enquiry does not need every production detail. It does need enough evidence to identify the part, the likely supply scope, and the questions that affect quotation.

What happens after you send the available evidence?

  1. 1
    Evidence review

    Open material, machining, finishing, quantity, inspection, packing, or delivery points are listed for discussion.

  3. 3
    Route definition

    The proposed casting, machining, finishing, and inspection scope is documented for manual review.

  4. 4
    Quotation basis

    The quotation records the files, assumptions, included scope, and commercial terms used for pricing.

Questions before quotation

Common RFQ preparation questions.

Final requirements remain tied to the controlled drawing, purchase order, and approved technical record.

Do I need a complete drawing package before requesting a review?

No. A 2D drawing, 3D model, physical sample, worn part, or clear photographs can start an initial review. Missing technical points can be identified before quotation or production release.

Can JK Casting review a sample or worn part without a drawing?

Yes. Clear photographs, measured dimensions, material clues, application details, quantity, and the physical sample can start the review. A controlled production drawing may still be required before release.

Does the RFQ readiness result approve manufacturing feasibility?

No. The result only organizes the information available for an initial review. JK Casting manually reviews manufacturing route, material, inspection, commercial scope, and delivery requirements.

Which files can I submit through the online RFQ form?

The form accepts one PDF, STEP, STP, IGES, IGS, DXF, DWG, ZIP, JPG, JPEG, or PNG file up to 8 MB. Multiple files can be combined into a ZIP file or sent by email.

Manual technical review

Send the strongest evidence available.

A complete package is useful, but it is not required for the first conversation. JK Casting will identify the technical and commercial points that still need clarification.
