AI-Powered supplier vetting

SummaryJINHUA STEEL CASTING AND ENGINEERING PARTS CO., LTD. is identified as a Chinese manufacturer/factory producing crusher and wear-resistant steel castings. The supplier reports three production lines, 50 years of combined R&D engineer experience, 6–10 quality-control staff, and annual manganese casting output of 10,000 tons; another description states annual production capacity above 5,000 tons. It reports that 71%–90% of sales are exports, has self-operated import and export rights, and began exporting in 2010. Listed management certifications include ISO 9000, ISO 9001, ISO 20000, GMP, and ISO 14064. The supplier states it supports major crusher brands and customer drawings, with professional designers and mold-making capability. SGS audit information is provided, but the stated audit evaluation result is 0 and the report validity ended on 2025-07-22. Overseas service facilities, formal R&D service categories, environmental documentation, and customer cases are not sufficiently evidenced.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and is registered as a limited company in China, with operations in Zhejiang. This supports direct manufacturing status rather than a purely trading or intermediary profile.

CertificationsThe supplier lists ISO 9000, ISO 9001, ISO 20000, GMP, and ISO 14064 certifications. An SGS audit record is also provided, but its stated evaluation result is 0 and the report expired on 2025-07-22; therefore, the current effectiveness and audit performance cannot be treated as fully positive.

R&D capabilityThe supplier reports 50 years of total R&D engineer experience and states that professional designers can implement new product development quickly. It also supports customer drawings, but the status of formal product-information R&D, ODM, 3D design, SDK, and environmental-development capabilities is unknown.

Production capacityThe supplier operates three production lines, reports 6–10 quality-control staff, and states manganese casting output of 10,000 tons, while another description reports annual production capacity above 5,000 tons. Its stated product range covers crusher wear parts and other steel castings, providing explicit evidence of substantial manufacturing capability.

Customization capabilityThe supplier explicitly states that it supports customer drawings and uses professional designers and efficient mold making to implement new product development. This directly supports drawing-based and mold-related customization, although the breadth of customization services is not otherwise quantified.
