AI-Powered supplier vetting

SummaryQingdao Yosion Intelligent Technology Co., Ltd. is identified primarily as a manufacturer/factory in China, although another record describes its company nature as a trading company. It develops, produces, sells, and services laboratory equipment, including automated sampling and preparation systems, crushers, pulverisers, furnaces, crucibles, and containerized laboratories. The supplier reports ISO 9001 certification, three production lines, stated output of 50 pulverisers and 1,000,000 crucibles, and export activity to multiple global regions since 2016. Its stated lead time is within 15 working days in off-peak periods and 2–3 months during peak periods. Evidence supports technical development, international sales, and claimed service activity, but information is insufficient to confirm financial strength, customization execution, or specific customer cases.

Supplier typeThe supplier is explicitly listed as a Manufacturer/Factory and describes itself as engaged in R&D, production, sales, and service for laboratory equipment. However, a separate record classifies its company nature as a trading company, creating a classification inconsistency that should be clarified.

CertificationsThe supplier explicitly reports holding ISO 9001 certification for its management systems. No additional certifications, certification scope, or validity details are provided.

After-Sales capabilityThe supplier states that it provides sales and service, meticulous service, and technical service, and claims that its service has received consistent customer praise. These statements support the existence of a service capability, although no specific after-sales procedures, service network, response times, or warranty terms are supplied.

R&D capabilityThe supplier explicitly reports R&D activity, independent R&D products, ongoing exploration and innovation, and cooperation with domestic and foreign scientific institutions to design and produce intelligent and modular laboratory equipment. It also reports 31–40 years of total R&D engineer experience, providing direct support for technical development capability.

Production capacityThe supplier reports three production lines and stated annual output of 50 pulverisers and 1,000,000 crucibles. It also provides lead times of within 15 working days off-peak and 2–3 months during peak periods, demonstrating established production operations, although capacity for its full product range is not specified.

Product Q&A

Q:What materials are used to make these cupels?

Cupels are typically made from magnesia (MgO), bone ash, Portland cement, and other materials. Our specific blend includes Magnesium Oxide and special fluxing ingredients.

Q:What are the available sizes for the cupels?

Standard sizes include 6A, 7A, 7AS, 7AL, 8A, and 9. Customized sizes are also available upon request.

Q:What are the key performance features of these cupels?

Key features include robust mechanical strength, no lead spitting, rapid litharge absorption, no cracking or pitting, easy bead removal, and reduced tendency to freeze.

Q:How does the cupel function in the fire assay process?

During cupellation, lead is oxidized to litharge and absorbed by the cupel, while gold, silver, and other precious metals form a bead for content determination.

Q:What are the terms of payment and shipping?

Payment terms include LC, T/T, PayPal, Western Union, and small-amount payments. Shipping terms are FOB, EXW, CFR, and CIF from Qingdao Port.
