Buyer FAQ
RFQ Questions Overseas OEM Buyers Usually Ask
These answers cover the practical checks buyers usually make before sending drawings, confirming material direction, or moving toward a trial order.
Can you quote with only a 2D drawing?
Yes. A 2D drawing is often enough for an initial process review and rough quotation. A 3D model helps shorten evaluation time when the structure is complex or machining and wall-thickness checks are critical.
Do you supply drawing-based castings in different metal materials?
Yes. Hongsen supports drawing-based custom metal casting projects and matches different casting routes according to part geometry, material direction, batch logic, machining needs, and delivery requirements.
What information should be included in an RFQ?
The most useful starting package is the drawing, material grade, quantity, annual demand, machining scope, inspection requirements, and target delivery timing. If the full package is not ready yet, application details and sample photos can still be used for review.
Can you support machining and inspection after casting?
Yes. Hongsen can coordinate casting, machining, inspection, packing, and export delivery for OEM buyers that need a complete manufacturing package.
Can we discuss the project before the final material or process is fixed?
Yes. Many overseas RFQs begin before the final route is locked. An early discussion based on part function, service condition, and batch expectation is completely normal.
Can drawings be sent directly by email or WhatsApp?
Yes. Buyers can send drawings, photos, and project notes directly to Hongsen by email or WhatsApp for a faster technical discussion.
