AI-Powered supplier vetting

SummaryThe supplier manufactures hydraulic cylinders and hydraulic lifting systems for dump trucks, engineering machinery, and other mechanical equipment. It provides customized design, development, selection, technical training, and after-sales support, with stated ODM and OEM capabilities. Evidence indicates structured quality, supplier-service, inspection, and corrective-action procedures, alongside multiple management and product certifications. Production resources include five production lines, 50 years of combined R&D engineer experience, 11–20 quality-control staff, and stated hydraulic-cylinder output of 300,000 sets. Overseas support is limited: no overseas warehouse, showroom, agent, branch, or offline trade-show participation is reported, although installation, training, repair, maintenance, and debugging services are listed. Financial information is represented only by year labels, so credibility cannot be assessed from the provided data.

Supplier typeThe supplier is a manufacturer of telescopic, engineering-equipment, mechanical-equipment, and hydro-pneumatic suspension cylinders, hydraulic lifting systems, and hydraulic components. Its five production lines and stated hydraulic-cylinder output support classification as a specialized hydraulic equipment manufacturer.

CertificationsThe supplier reports QHSE, OHSAS/OHSMS 18001, TS 16949, and ISO 9001 supplier-management certifications, plus China safety and environmental, occupational health and safety, integrated management, and DCMM Level 2 certifications. Products are stated to have IATF16949 and Coal Mine Safety Mark certifications, with additional ISO45001:2018, ISO14001, and CE-related capability reported.

After-Sales capabilityThe company states that it provides technical training and after-sales service, and lists equipment installation, training, repair, maintenance, and debugging among its overseas service offerings. Service management has written procedures, records, approved-supplier information, and corrective/preventive-action procedures, but no overseas warehouse, showroom, agent, branch, or offline trade-show participation is reported.

R&D capabilityThe supplier reports new products within the past year, ODM capability, broad R&D customization services, and 50 years of combined R&D-engineer experience. However, no SDK is available; this limits evidence for software or platform integration capability but does not negate the demonstrated product-development capability.

Production capacityProduction evidence includes numerical-control machine tools, a Longmen machining center, five production lines, 11–20 quality-control staff, and stated hydraulic-cylinder output of 300,000 sets. The supplier also reports finished-product inspection instructions that are uniformly followed and an off-season average lead time within 15 workdays.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. Its company description also covers customized preliminary design, development, product selection, and design-scheme finalization, indicating broad engineering customization support.

Client casesThe product portfolio is identified for dump trucks, mechanical equipment, engineering machinery, and hydraulic systems, and the supplier states that it provides OEM services for well-known brands. Specific customer names, project references, order histories, or verifiable case studies are not provided.

Product Q&A

Q:Are you a factory or a trader?

We are a factory, and in China we are a leading enterprise in the hydraulic industry. We have two factories covering an area of 180,000 square meters, with more than 700 employees and more than 1,000 sets of production equipment.

Q:Do you support OEM and ODM?

We can accept both OEM and ODM.

Q:What is your after-sales service?

Our products come with a 14-month warranty. If any quality issues arise during this period, we will replace the parts for free for maintenance, or directly replace the new cylinder. We also provide pre-sale communication, sale training, and 24-hour telephone service.

Q:Do you have any cylinder surface treatment processes?

Our company has 6 complete surface treatment production lines. We can perform chromium plating, zinc plating, copper plating, copper melting, QPQ, and laser cladding.

Q:How to ensure the cylinder sealing performance?

We use high-quality imported or domestic first-line brand seals (such as Hallite, Longli, etc.). Our cylinders will undergo pressure resistance tests and pressure holding tests higher than the rated working pressure before leaving the factory to ensure long-term stable operation without leakage within the rated pressure range.
