AI-Powered supplier vetting

SummaryQingdao Conringwon Automation Technology Co., Ltd. is a Chinese limited-company factory established in 2016, located in Qingdao, Shandong. The supplier offers conveyor systems, precision machining, welding, casting and forging, and automation equipment. It reports export activity since 2017, self-operated import-export rights, and export sales representing 31%–40% of total sales. Evidence indicates ISO9001:2015 certification, six production lines, 21–30 quality-control staff, five R&D engineers, and stated machinery and machining capacities. The supplier provides OEM and ODM services and describes successful logistics transportation, petroleum refining, and textile machinery projects. However, after-sales processes, financial credibility, and independently verified customer references are not sufficiently documented.

Supplier typeThe supplier is identified as a limited company and factory in Qingdao, Shandong, China, operating in manufacturing. Its listed product scope includes conveyor systems, precision machining parts, welding services, casting and forging, and automation equipment.

CertificationsThe supplier reports holding an ISO9001:2015 management-system certificate along with unspecified additional certifications. The available evidence confirms certification is claimed, but does not provide certificate scope, validity dates, or the identity of the other certifications.

R&D capabilityThe supplier reports five R&D engineers, OEM and ODM design-development services, continuous improvement and innovation objectives, and engineers with more than 15 years of machinery-production-line experience. Its listed CNC, laser-cutting, bending, welding, and machining equipment supports engineering execution, although independently verified innovation outcomes are not provided.

Production capacityThe supplier reports six production lines and capacities covering machinery, steel structures, machining parts, welding structures, and CNC-machined parts. It also describes two factory zones totaling 14,500 square meters and a broad equipment base, while employee figures differ across records: 78 employees in the company profile versus more than 150 claimed in the description.

Customization capabilityThe supplier explicitly offers OEM and ODM services, states that its engineers can design and develop products according to customer requirements, and specializes in customized CNC machining, conveyor rollers, precision parts, and welded frame parts.

Product Q&A

Q:What is the maximum part size your large gantry machining centers can handle?

Our gantry machining centers handle parts up to 12000 mm in length and 4000 mm in width. Larger custom weldments can be discussed.

Q:Do you provide welding certificates for your international welders?

Yes. Our welders hold ISO certification. We provide WPS and welder qualification records on request.

Q:What machining tolerances can you achieve on large welded components?

We typically hold +/-0.02 mm on critical bore diameters and +/-0.05 mm on positional tolerances for parts up to 5000 mm.

Q:Can you work with customer drawings and custom materials?

Yes. We are build-to-print. You supply drawings (PDF, DWG, or STEP) and we machine per your specifications using structural steel, stainless steel, or wear-resistant plates.

Q:What is your typical lead time for a large welded and machined assembly?

Lead time is 3 to 6 weeks depending on complexity and material availability. Expedited service is available for urgent orders.
