SummaryCungang Mold Fittings Co., Ltd. is a China-based limited company established in 2014 with 63 employees and a valid import/export license. Its stated product scope covers mold accessories, mold materials, bench drill accessories, machine tool accessories, and guide-related mold parts. The supplier reports ISO9001:2015 and CE certifications, 3D software design services, broad customization options, 10 R&D engineers, and new product development during the past year. It has exported for 11 years, with exports representing 31%–40% of sales. Service procedures exist, but some areas lack documented records, including supplier service assessment and complaint handling. No cooperation with Fortune 500 companies is reported. Financial information is insufficient for a substantive credibility assessment.

Supplier typeThe supplier is a China-based limited company established in Zhejiang in 2014, with 63 employees and no stated parent-group affiliation. Its business focuses on mold accessories, mold materials, and related machine-tool products, and it holds an import/export license.

CertificationsThe supplier reports both ISO9001:2015 management-system certification and CE product certification. These certifications provide explicit evidence of quality-management and product-compliance credentials, although the supplied information does not specify the certified product scope or validity dates.

After-Sales capabilityThe supplier has a corrective and preventive action procedure with records, but its service-capability assessment procedure has no records and its customer-complaint procedure has no written records. This demonstrates some formal process capability while also identifying documentation weaknesses in complaint and service evaluation activities.

It also states that its R&D capability supports customization from samples and designs, minor customization, full customization, and flexible customization, indicating active product-development capacity.
