Mainly used for machine tool castings under 5 tons and similar structural projects that later move into large-part machining.
Supports larger-section machine structures without moving into ultra-heavy casting territory
Useful for machine bases and gantry-style industrial projects
Connects naturally with large CNC machining and inspection follow-up
Casting Line
Resin Sand Casting Line
Line Overview
The resin sand line supports medium and larger industrial castings where structural stability, machining allowance, and broader geometry coverage are all important.
Best Fit Parts
A strong route for machinery parts, large gantry machine castings, Haas machine-related castings, and general industrial structural components.

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 recommends suitable casting routes according to part geometry, material requirements, production volume, machining needs, and delivery expectations.
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.
RFQ Focus
Have a Metal Casting Drawing?
