A 2D drawing, 3D model, sample photo, or existing part photo can be enough to start.

Send The Drawing First, Then Complete The Project Step By Step
For drawing-based metal casting projects, the best starting point is usually not a fully completed form. It is the drawing, sample photos, or the key technical package that lets the first review begin quickly.

RFQ Quick Reference
What information is enough to start the first review
The first RFQ does not need every technical detail to be final. Send the key files and project requirements first, then Hongsen can check whether the package is ready for quotation review.
Project notes
Application, quantity, annual demand, material direction, machining scope, and inspection expectations make the first response faster.
First feedback
The first review usually checks material direction, casting route, machining focus, inspection risk, and missing information.

Send The Drawing Files And References First
2D drawings, 3D models, and sample photos are all supported. Even one file is enough to begin the first review.

For industrial casting projects, buyers do not always have every detail fixed in the first RFQ. If the part includes a 3D model, complex internal geometry, lightweight structure, or prototype validation need, it can still be sent first for early review.

Factory Proof
The Trust Signals Buyers Usually Check Before Sending Files
- Manufacturing base operating since 2002 with multiple casting routes
- Machining, inspection, and export coordination are part of the first review
- When the package is clear enough, initial feedback usually begins within about 24 hours
Direct Contact
If Your Drawing Package Is Already Ready, You Can Also Send It Directly
The form helps structure the RFQ. If the buyer already has a clean drawing package, email or WhatsApp can also be used to start quickly.
What Hongsen Reviews First
The First Review Focuses On Technical Fit, Not Generic Sales Language
- Which casting route likely fits the geometry best
- Whether the material direction, machining scope, and inspection focus look reasonable
- Which missing point matters most if the package is still incomplete
Good Projects For This Flow
These Project Types Usually Fit An Early Drawing Review Best
- 2D or 3D drawing is already available
- Casting, machining, and inspection need to be considered together
- The program starts with a sample order or pilot batch first
Do Not Wait For Every Detail
The Review Can Still Start Even If The Final Grade Is Not Fully Locked
- Application details and a likely material direction are often enough to begin
- Quantity, annual demand, or inspection scope can still be estimated at this stage
- Sending the drawing early usually moves the RFQ faster than waiting for a perfect package
