ENGINEERING REVIEW & QUOTATION
Send your drawing, BOM or project requirements for manufacturing review. A drawing gives the fastest route to a useful technical review, but you can still start with basic project information when files are not yet ready to share.

Required fields are kept to the information needed for an initial review. Complete technical inputs reduce clarification cycles, but drawing files remain optional until your project is ready to share them.
What Helps Us Review Your Project
Drawing / BOM
2D/3D drawing, BOM or a clear sketch showing the part, assembly and current revision.
Material / Finish / Quantity
Material grade, finish requirement and prototype or production quantity when known.
Critical Requirements
Critical tolerances, inspection needs, application, assembly requirement and target delivery requirement.
Choose the Most Relevant Project Route
Sheet Metal RFQ
Include drawing/CAD, material and thickness, quantity, bending/welding requirements, finish, hardware and critical inspection points when known.
CNC Machining RFQ
Include 2D/3D drawing, material grade, quantity, critical tolerances/threads/fits, surface requirement and any required inspection records.
Welding / Assembly RFQ
Include assembly drawing or BOM, material, overall size, quantity, weld/fabrication requirements, purchased hardware, finishing, inspection and packaging needs.
Mixed-process projects can combine these routes. The engineering review determines the practical manufacturing sequence after the submitted information is checked.

What Happens After Submission
1. RFQ Received
Your project information is received for initial review.
2. Engineering Review
Drawing, material, quantity, tolerances, process route and any missing requirements are checked.
3. Route & Quotation
We clarify open points, confirm the practical manufacturing route and prepare the quotation when the inputs are sufficient.
Quotation and lead-time preparation depend on drawing complexity, quantity, material, process, finishing and inspection requirements. LIUMAI does not present one fixed quotation time for every project.
Drawing File Security
Accepted manufacturing files are validated before storage and saved outside the public WordPress media directory. CAD and BOM files are not attached to notification emails and are not exposed through normal public upload URLs.
PROCUREMENT FAQ
Questions Buyers Commonly Ask
Is a drawing mandatory to submit an RFQ?
No. A drawing is strongly recommended, but buyers at an early or confidentiality-sensitive stage can submit company information, project type, quantity, application and key requirements first.
Which files can be uploaded?
The secure RFQ system accepts controlled engineering file types including PDF, STEP or STP, IGES or IGS, DWG, DXF and ZIP, subject to file validation and size limits.
Are uploaded drawings placed in the public WordPress media library?
No. RFQ files are stored outside the public web root with randomized server filenames and restricted administrator download access.
What happens after submission?
The normal route is RFQ receipt, engineering review, manufacturing-route or clarification questions, quotation, sample or prototype where required, and production after commercial approval.
