The supplier reports CNC and inspection equipment, 10 production lines, and 6–10 quality-control staff. It states that products can be made to customer drawings and dimensions, with a maximum product size of 2,000 mm, and lists multiple management-system certifications, including ISO 9001 and API-related certifications. Export activity reportedly began in 2023, while export sales represent 1%–10% of total sales. Evidence is insufficient to assess after-sales capability, financial credibility, innovation capability, or customer cases.

The formal supplier-type field and the company’s stated manufacturing address support manufacturer status, although the conflicting classification should be clarified.

These declarations provide explicit evidence of certification holding, although certificate validity and scope are not supplied.

Production capacityProduction capability is supported by 10 production lines, 6–10 quality-control staff, CNC and testing equipment, a stated maximum product size of 2,000 mm, and a broad range of gasket products and materials. The supplier also identifies specialized ring-joint and flange-gasket applications, indicating established product manufacturing scope.

Customization capabilityThe supplier explicitly states that it can manufacture according to customer-specific dimensions or drawings, with products up to 2,000 mm, and can supply products in approximately 30 material types. This directly supports customization in dimensions, drawings, and material selection.
