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: What is the real air flow at 8 bar for this 75 Kw PM VSD unit?

A: About 12.3 m3/min at 8 bar, 11.6 at 10 bar, 10.2 at 13 bar per ISO 1217. VSD modulates 30 to 100 percent of this range to follow jack hammer duty cycle.

Q:Q2: Why oil cooled PM motor instead of air cooled for jack hammer use?

A: Tunnel and quarry sites have silica dust and 40 to 50 degree ambient. Oil cooling circulates compressor oil through motor jacket, keeping magnet under 120 degree and IP65 rating blocks dust entry. Air cooled PM motors demagnetize faster in such sites.

Q:Q3: Can it run 4 jack hammers at once?

A: Yes. A single 5/8 inch jack hammer consumes 0.9 to 1.2 m3/min at 6 to 7 bar. 12.3 m3/min supports 4 to 5 hammers with margin for hose loss. For 6 plus tools pick 90 to 110 Kw class.

Q:Q4: What voltage and start method are standard?

A: 380V/50Hz/3phase VSD soft start standard. Custom 415V/50Hz, 440V/60Hz, 460V/60Hz with ABB or Inovance inverter. No star delta, no contactor wear.

Q:Q5: Is stationary only or can it be skid or trailer mounted?

A: Base model is stationary with lift eyes. Optional skid frame with drag hooks or trailer chassis with lights and brakes for jobsite move between tunnel faces.
