AI-Powered supplier vetting

SummaryDongguan Walle Sealing Technology Development Co., Ltd. is a China-based limited company classified as a trade company, associated with the manufacturing industry and focused on sealing products. It reports ISO9001 certification, five production lines, a 2,000 m² plant, 27 employees, and stated annual output of 2,000,000 boxes of rubber seals, oil seals, and O-rings. The supplier exports extensively, with 71%–90% of sales from exports and markets across multiple regions. It supports OEM orders and describes engineering research, technological innovation, advanced production and testing equipment, and sealing solutions for numerous industries. Order fulfillment is stated as one month in both peak and off-peak periods. Evidence is insufficient to assess after-sales service depth, financial credibility, or specific customer cases. The records also contain inconsistent experience claims: one slice states three years of R&D engineer experience, while another claims over 20 years of production and R&D staff...

Supplier typeThe supplier is identified as a limited company in China, classified as a trade company, with associated companies in manufacturing and operations centered on sealing-product development and production. Its stated commercial categories include industrial equipment, machinery, tools, automotive parts, and manufacturing-related products.

CertificationsThe supplier explicitly reports an ISO9001:2015 certificate. Another description references ISO9001:2008, but the records do not clarify whether this is an older certificate or a separate status; the current explicit certification evidence is ISO9001:2015.

R&D capabilityThe supplier explicitly describes engineering research, technological innovation, multiple sealant formulations, advanced production and testing equipment, and the use of materials and technology for demanding environments. The evidence supports stated innovation activity, although the record also reports only three years of total R&D engineer experience and does not provide patents or quantified R&D results.

Production capacityThe supplier reports a 2,000 m² manufacturing plant, five production lines, 27 employees, and annual output of 2,000,000 boxes of rubber seals, oil seals, and O-rings. It states one-month fulfillment during both peak and off-peak periods and describes production of seals for multiple industrial applications, providing explicit evidence of operational production capacity.

Customization capabilityThe supplier welcomes OEM orders and states that it develops varied sealing formulations and solutions using different materials and technologies for demanding operating environments. Its broad product range includes synthetic rubber, PTFE, hydraulic, cylinder, PU, FKM, perfluoroelastomer, oil and gas, chemical, pump, and valve seals, supporting customization capability.

Product Q&A

Q:What materials are used for the seals?

The seals are made from virgin PTFE with a spring energizer.

Q:What are the main applications?

Suitable for hot water valves, accumulators, hydraulic/pneumatic cylinders, food processing, medical, chemical technology, and aerospace jet engines.

Q:How does the seal function?

The lip and spring are compressed during installation. The spring provides constant force, and system pressure expands the seal to increase sealing force.

Q:Is customization available?

Yes, OEM and ODM services are welcome. Standard and nonstandard shapes are available.

Q:What are the shipping times?

Express takes 3-5 days, air freight takes 3 days, and sea freight takes 15-30 days.
