AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization, ODM and OEM capabilities, reports new product development within the past year, and operates CNC, five-axis and three-coordinate machining facilities. Production information states annual output of 100,000 air-compressor pieces and 10 quality inspectors, although finished-product inspection instructions are not supported by written records. Service procedures, corrective actions and complaint handling have documented procedures and records. The supplier offers in-stock capacity and service offerings in Russia, but has no overseas warehouse, showroom, agents or branches. Certifications include ISO9001:2015, ISO45001:2018, ISO14001 and CE. ERP, OA, CRM and SAP systems are reported. Financial credibility cannot be assessed because the supplied financial slices contain inconsistent and incomplete figures, which are not reproduced here. A known-brand OEM claim is provided, but no specific customer names or case details are available.

Supplier typeThe supplier provides ODM services, OEM services for known brands, and operates CNC machining, five-axis machining and three-coordinate machining facilities. This supports classification as a manufacturer with design, machining and OEM/ODM capabilities.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018 and ISO14001 certifications, as well as CE product certification capability. These are explicit certification holdings or capabilities in the provided data.

After-Sales capabilityThe supplier has documented procedures and records for service assessment, corrective and preventive actions, and customer complaints. It offers debugging, maintenance and repair services in Russia, but has no overseas agents or branches; therefore, the documented service process and stated offerings support a positive assessment, while geographic coverage is limited.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and supports customization from samples, designs and full specifications. It does not have an available SDK, but the stated product-development and ODM evidence supports innovation capability.

Production capacityThe supplier reports annual productivity of 100,000 air-compressor pieces, 10 quality inspectors, CNC-based machining facilities, valid contracts with associated subcontractors, in-stock capacity and a one-month average lead time in both peak and off-season. Finished-product inspection has instructions but no written records, indicating a documented-control limitation but not an explicit failure of production capability.

Customization capabilityBoth R&D and design-service records list customization from samples, customization from designs, full customization, minor customization and flexible customization. The repeated and comprehensive customization scope is explicit evidence of strong customization capability.

Product Q&A

Q:Q1: Is 250 cfm enough for 4 jack hammers?

A: Yes. One 5/8 inch jack hammer uses 0.9-1.2 m3/min at 6-7 bar. 250 cfm (7.0 m3/min) runs 4-5 hammers with margin for hose loss. For 6 plus tools pick 300-375 cfm class.

Q:Q2: What is the fuel consumption of the 78 Kw Cummins unit?

A: Cummins 4BTA 78 Kw burns 20-24 L/h at full load 8 bar, 7-9 L/h at auto idle hold. Yuchai version similar. Auto idle trims 12-15 percent in partial load.

Q:Q3: Can pressure be adjusted between 7 and 10 bar on site?

A: Yes. Controller has 7/8/10 bar preset, throttle modulates to hold set pressure. For 13 bar we supply two stage airend version.
