How we research, rank and correct content

1. Scope and purpose

We publish practical reference material for industrial machinery buyers: what a machine category does, how to compare options, what drives cost, and which manufacturers are active in that category. Content is written for procurement and engineering readers, not for consumers.

2. Research and sourcing

• Primary sources first. Manufacturer datasheets, official product pages, operating manuals and published technical standards.
• Secondary sources — trade associations, exhibition catalogues, industry reports — are used for market context and always attributed.
• Cross-checking. Specifications that affect a buying decision (capacity, speed, power, materials, certifications) are checked against at least one manufacturer source.
• Uncertainty is stated. When supplier data conflicts or is unavailable, the page says so and gives a range instead of a false precision.

3. Citations and verification dates

Guides and rankings include a citation block listing the sources used, and pages carry a last-verified date. A page is re-checked when a manufacturer changes its product line, when a cited source disappears, or when a reader submits a substantiated correction.

4. AI assistance

We use software tools, including AI-assisted drafting and translation, to help structure and edit research. They are tools, not sources: specifications and claims still have to be traced back to a manufacturer or standards document before publication, and every page is reviewed by our editorial team before it goes live. If you believe a page contains machine-generated text that is inaccurate or unsupported, report it via the contact page and we will review it.

5. How rankings are built

• Inclusion criteria are stated on each ranking page — equipment focus, verifiable product range, geographic scope and available company information.
• Ranking factors are published with the list. We do not rank on impressions alone, and we do not rank companies we cannot verify exist and manufacture the equipment.
• No paid placement. A supplier cannot buy a position, and advertising has no influence on the order of a ranking.
• Separate labels. Global and China-focused rankings are identified as such, and a company's country of origin is stated.

6. Updates and corrections

We correct factual errors when they are identified. To report one, contact us with the page URL, the statement you believe is wrong, and a source that supports the correction. Verified corrections are applied to the page and the page's update date is refreshed. Where a correction changes a ranking materially, the change is noted in the page's update history.

7. Independence and disclosure

Global Machinery Hub is operated by 佛山市科世云科技有限公司. We do not manufacture or sell machinery. The site may link to manufacturer websites for verification; those links are editorial, not paid placements, and a link does not imply endorsement of every product a company sells.
