AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier focused on hydraulic power machinery, components, pumps, vacuum equipment, mechanical parts, hardware, and technical services. It supports extensive customization and provides ODM and OEM services, but does not provide 3D software design, SDKs, or new products. Export orientation is strong, with 90% of sales from exports and self-operated import/export rights, while overseas service infrastructure is limited: no overseas agents, branches, warehouses, showrooms, or offline trade-show participation. Quality inspection procedures are documented, but certification-system status is NIL and sustainability controls show gaps. Production scale is reported as above the stated threshold, although detailed capacity evidence is limited.

Supplier typeThe supplier explicitly identifies as a professional technical supplier. Its stated business scope covers hydraulic power machinery and components, liquid-tight components and systems, pumps and vacuum equipment, mechanical parts, hardware products, and technical services; its primary export market is South America.

CertificationsThe supplier’s certification of management systems is recorded as NIL. This is explicit evidence that no management-system certification is reported in the provided information.

After-Sales capabilityThe supplier has no in-stock service capability, overseas warehouse, overseas showroom, overseas agent or branch, and offers overseas services in zero countries. Service management has written procedures but no records, indicating limited documented after-sales infrastructure.

R&D capabilityThe supplier has R&D capability and provides ODM services, but it does not provide 3D software design or SDKs and reported no new products during the past year. The evidence supports some product-development capability but also identifies clear limitations in software/tooling and recent innovation output.

Production capacityAnnual production output is reported as above the stated threshold, and finished-product inspections follow written instructions uniformly. However, the supplier has no in-stock capability, while outsourcing procedures and manufacturing-capacity contracts are unknown; therefore, production scale is indicated but operational depth is only partially evidenced.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. It also provides ODM and OEM services for well-known brands, directly supporting broad customization capability.

Product Q&A

Q:How do I determine the correct cylinder size from a sample?

Measure the outer diameter of the cylinder, the length between pin holes (with the rod fully retracted), the push/pull rod diameter, and the pin diameter. This data helps identify the cylinder specifications.

Q:What are the ways to order the correct size?

You can send us a drawing, measure the sample size, send the physical sample, or refer to our chart. Order primarily by length, then match the rod and bore sizes as closely as possible.

Q:What is the difference between double acting and single acting cylinders?

Double-acting cylinders have ports at both ends for hydraulic fluid to extend and retract the rod. Single-acting cylinders have one port; fluid extends the rod, and an external force or gravity returns it.

Q:What paint colors are available?

Standard colors include Red, Black, Yellow, Blue, and Brown. Other colors can be customized according to your requirements.

Q:Can we customize the packaging or print our logo?

Yes, we can manufacture the package and print your logo according to your specific requirements.
