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.

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:What is the brand name of your products?

Generally, we use our own brand 'WTJX', OEM is also available as required.

Q:What causes hydraulic cylinder internal leakage?

There are 3 main reasons causing internal leakage: Overload, polishing is not well controlled, bad seal kits. Our products are designed to bear overload power, use numerical control machines for polishing, and imported seals.

Q:Does your piston rod get ruptured easily?

Hard chrome plating quenched and tempered 45# steel for piston rod to assure sufficient hardness and toughness.

Q:What is the quality feedback of your products?

Guarantee the quality from the raw material. We have cold drawing production line and nickel-chrome electroplating production line, so we can produce cold-drawing pipe and hard-chrome pipe used for hydraulic cylinder!

Q:Can the hydraulic cylinders be customized?

Yes, the Hydraulic Cylinders can be made according to client's requirements including stroke, working temperature, and pressure.
