2D drawings are usually the minimum starting point, while 3D files help on more complex parts
RFQ Preparation Guide
What Buyers Should Prepare Before Sending A Casting RFQ
Many RFQs slow down not because the part is difficult, but because the first package is incomplete. This guide helps buyers prepare the drawing set, project notes, and technical details that usually make the first casting review clearer and faster.

Why The First RFQ Package Matters More Than Buyers Expect
A stronger RFQ package reduces clarification loops. It helps the supplier judge material direction, process fit, machining scope, and inspection priorities earlier instead of spending the first round asking for missing basics.
Material direction can be discussed even when the final grade is not fully fixed yet
Quantity, annual demand, and trial-order timing affect process and cost logic
Machining faces, tolerance zones, and inspection expectations should be shared as early as possible
Project Fit
What A Good RFQ File Guide Should Solve First
A useful RFQ-preparation guide does not force the buyer to complete every detail up front. It helps the buyer understand which files matter first and which points can still be clarified during the technical review.
What is usually enough to begin the first review?
The drawing, application, quantity, and critical machining faces are often enough to start a useful technical discussion.
What can still be sent even if it is not fully fixed yet?
Final material grade, some machining details, and formal inspection documents can often be refined later.
How can buyers reduce time lost in repeated clarification?
The earlier the buyer shares service conditions, annual demand, and critical dimensions, the fewer loops the first review usually needs.

What Information Usually Helps The First Review Move Faster
The most useful RFQ package combines geometry, application context, quantity logic, and downstream manufacturing needs instead of only attaching one drawing file.
2D drawing and 3D model if available, especially for complex structures or machining-related parts
Part application, service condition, pressure or wear notes, and destination market if relevant
Material grade or at least the intended material direction if the final grade is still under discussion
Quantity, annual demand, trial-order expectations, machining scope, tolerances, and inspection requests

対象プロジェクト、検討範囲、RFQに必要な情報をまとめています。
What To Prepare First
2D drawing, 3D if available, application notes, quantity, and key machining points
Best Fit
Overseas buyers, engineers, and sourcing teams preparing the first RFQ
Project Relevance
It reduces back-and-forth and helps the first review move into practical discussion faster
Fastest Way To Start
Send the core package first and refine uncertain details during review
Reference Visuals
What Visuals Make An RFQ File Guide More Useful
Drawing review, machining checkpoints, and inspection expectations are usually more helpful here than one general factory image alone.

Inspection And File Completeness Mindset
Helps explain why the first RFQ package should be clearer.

Critical Machining Faces And Dimension Priorities
Reminds buyers which machining-related notes are useful to share early.

Real Parts And Project Context
Keeps the RFQ checklist grounded in actual part programs instead of abstract requirements.

Next Step
Sending The Core Package Now Is Usually Better Than Waiting For Every Detail
If you already have the drawing and basic project notes, Hongsen can start the first review before every open detail is fully fixed.
Start With A Drawing Review
The earlier Hongsen receives the drawing, quantity plan, material direction, and machining notes, the faster the first review can begin.
Review Manufacturing Capability
Confirm whether the current casting lines, machining support, and export coordination fit the project scope.
Review Quality Control
If consistency, inspection scope, and delivery stability matter most, continue to the quality-control page.
Buyer FAQ
Questions Buyers Ask When Preparing A Casting RFQ
These questions are useful when the buyer is still organizing files or deciding what to send in the first email.
Can the review begin with only a 2D drawing?
Yes. A 2D drawing is often enough for an initial screen. A 3D model helps when the geometry is more complex or when machining and internal features need closer review.
What if the final material grade is not locked yet?
The RFQ can still start. Buyers can share the service condition, application, and expected performance so the material direction can be reviewed before the final grade is fixed.
Do buyers need to define every machining detail before sending the RFQ?
Not always. The more useful approach is to clearly mark critical machining faces, tolerance-sensitive areas, and assembly-related features so the supplier can review the likely scope.
