AI-Powered supplier vetting

SummaryShandong Rongye Machinery Co., Ltd. is identified as a limited-company trading company with three employees and no stated affiliation with a larger group. It offers customization from customer designs and accepts several international trade and payment terms, with a stated one-month average lead time in both peak and off-season. However, the available information indicates no overseas showroom, overseas agent or branch, overseas-service coverage, offline trade-show participation, ODM service, SDK, recent new-product launches, or OEM work for popular brands. The supplier holds ISO9001:2015, ISO45001:2018, and ISO14001 certifications and reported regular fire drills. Service procedures exist for supplier assessment, corrective actions, and complaints, but no written records were provided. Financial-related entries identify reporting years but do not provide sufficient evidence to assess financial credibility. Customer-case evidence is limited, with no Fortune 500 cooperation and zero stated repeat buyers.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications. A TUV Rheinland audit is also listed with a validity period from September 3, 2025 to September 2, 2026, but the recorded audit evaluation result is 0 and the meaning of that value is not defined in the provided data.

After-Sales capabilityThe supplier has procedures for corrective and preventive actions, customer complaints, supplier assessment, and service quotations, but no written records were provided for these procedures. It has no overseas showroom, overseas agent or branch, overseas-service coverage, or prior offline trade-show participation, limiting evidence of international after-sales support.

R&D capabilityThe supplier has one R&D engineer and can customize from customer designs, but reports no new products in the past year, no ODM service, and no available SDK. These stated limitations indicate weak demonstrated innovation capability.

Customization capabilityBoth relevant records state that the supplier provides customization from customer designs. This is explicit evidence of design-based customization, although it does not establish broader ODM or independent product-development capability.

Client casesThe supplier reports no cooperation with Fortune 500 companies and a repeat-buyer count of zero. No other named customer cases or reference projects are provided, so the available evidence does not demonstrate an established customer track record.

Product Q&A

Q:What is the function of the Quick Exhaust Valve QF-514B?

It is designed to drastically increase the retraction or exhaust speed of pneumatic actuators by providing a direct path for air to escape.

Q:How does the valve operate?

It functions as a one-way, three-port valve. When supply pressure is cut off, it opens a direct path from the actuator to the atmosphere, reducing backpressure.

Q:What is the cracking pressure of the valve?

The cracking pressure is less than 0.05 MPa, ensuring it opens with minimal resistance.

Q:Is the color of the valve customizable?

Yes, the color is customizable.

Q:What materials are used to construct the valve?

It is constructed from lightweight yet robust glass-reinforced nylon with an internal NBR diaphragm or poppet.
