SummaryTaizhou Sihai Machinery Co., Ltd. is a China-based limited company established in 2003, with 103 employees and operations in Taizhou, Zhejiang. The supplier is associated with both manufacturing and trading classifications and focuses on gearboxes, gearmotors, reducers, and speed variators. It reports more than 10 production lines, a 14,500 m² manufacturing plant, ISO9001:2015 certification, 10 years of R&D engineer experience, and 6–10 quality-control staff. The company has held self-operated import/export rights since 2006, exports 51%–70% of sales, and serves markets across Southeast Asia, the Middle East, East Asia, North America, and Europe. Its stated one-month lead time applies in both peak and off-peak seasons. Evidence supports production capacity, export experience, quality-system certification, and stated after-sales commitments. However, the slices do not provide sufficient evidence to verify financial strength, customization capability, or specific customer cases.
Supplier typeThe supplier is legally identified as a limited company established in China, while its business classifications include both manufacturing and trading. Its stated commercial activity is manufacturing and processing machinery, with products centered on gearboxes, gearmotors, reducers, and related accessories.
CertificationsThe supplier reports an ISO9001:2015 management-system certificate. Additional company descriptions refer to ISO9001:2008 compliance and certification, indicating a documented quality-system history, although the slices do not independently verify certificate validity or scope.
After-Sales capabilityThe supplier explicitly identifies excellent after-sales service and customer satisfaction as company principles. Its descriptions also claim quality-focused service and a good market reputation, but no specific service team size, warranty terms, response times, or service locations are provided.
R&D capabilityThe supplier states that innovation is a core principle and reports 10 years of total R&D engineer experience. This supports some innovation-related capability, but the slices do not identify patents, dedicated R&D facilities, new-product development records, or measurable innovation outcomes.
Production capacityProduction capability is supported by more than 10 production lines, a 14,500 m² manufacturing plant, 103 employees, and a stated one-month order-fulfillment time in both peak and off-peak seasons. The supplier also identifies manufacturing and processing machinery as its commercial activity and lists a broad range of gearbox and reducer products.
Client casesThe supplier reports exports to Southeast Asia, the Middle East, East Asia, North America, and European countries, and one trade record identifies GEARLINC SYSTEMS as a buyer. These references demonstrate international market activity, but the evidence contains only one named buyer and does not provide detailed project outcomes, order history, or verifiable customer case studies.
