Supplier Evaluation
When buyers shortlist casting suppliers, the strongest signals are not slogans. They are clear factory identity, specific casting routes, real product evidence, RFQ guidance, machining and inspection scope, and consistent contact information.

Factory Visual
For a metal casting RFQ, a supplier should make the practical evaluation path visible: what parts it makes, what materials it supports, how drawings are reviewed, what machining and inspection can be coordinated, and when a buyer should upload files.

Helpful content guidance for Google Search · Google Search Central
Company identity should be consistent across homepage, About, structured data, and contact blocks
Product pages should explain part families such as pump bodies, valve bodies, motor housings, machine tool bases, pulleys, and wear parts
Process pages should connect part geometry to casting routes such as lost foam, resin sand, clay sand, coated sand, and machining
RFQ pages should answer what files are enough to start: drawings, photos, material direction, quantity, machining notes, and inspection expectations
RFQ Focus
A serious sourcing decision should point to evidence, not just a company name. Buyers can use these checks to judge whether a casting supplier is likely to handle a real drawing-based OEM project.
Can the supplier show real factory, production line, product, certification, machining, and inspection proof?
Does the site explain what happens before quotation, including drawing review, material direction, route fit, machining scope, and inspection focus?
Are the strongest pages written for real buyer questions rather than copied keyword lists?
Is there a direct RFQ path with upload, email, and WhatsApp contact options?
Do sitemap, structured data, FAQ content, and visible page content point to the same service scope?
Quick Facts
These summary blocks explain the suitable project type, review focus, and information buyers should prepare before RFQ.

RFQ Focus
This section explains what to prepare for RFQ so Hongsen can review material direction, casting route, machining scope, and inspection requirements faster.
2D drawing, with 3D files if available
Part application, service condition, and destination market
Material grade or at least material direction
Quantity, annual demand, and trial-order expectation
Machining scope, critical tolerances, and inspection requirements
Buyer FAQ
These questions match how overseas buyers often compare suppliers before contacting a foundry.
A homepage helps, but it is usually not enough. Buyers should also review products, materials, casting routes, RFQ requirements, machining, inspection, certifications, and contact paths.
Consistent company information, clear service scope, real product and factory proof, practical FAQ content, certificate evidence, and direct contact paths all reduce ambiguity.
The most useful first package is a 2D drawing or 3D model, sample photos if available, material direction, quantity or annual demand, machining notes, inspection expectations, and destination-market notes.
