AI-Powered supplier vetting

SummaryThe supplier is identified as a factory with activities spanning battery manufacturing, new-energy technology research, mechanical and electrical equipment, testing machines, and graphite/carbon products. It demonstrates broad customization and R&D capabilities, including full customization, ODM services, and new-product development during the past year. It also reports OEM service for well-known brands, quality-assurance procedures, complaint-handling records, material traceability, and participation in an overseas trade show. Production evidence is available for hydrogen water bottles, with an annual output of 8,000–20,000 units. However, the supplier has no available SDK, overseas warehouse, overseas showroom, or overseas agents/branches. Financial information is present only as year labels, without sufficient evidence to assess credibility.

Supplier typeThe supplier is explicitly classified as a factory, indicating an in-house manufacturing identity rather than only a trading or service intermediary.

After-Sales capabilityThe supplier has a clear customer-complaint handling procedure with followed records, along with quality assurance and raw-material traceability. This directly supports structured after-sales issue handling, although broader service coverage is not stated.

R&D capabilityThe supplier reports new-product development during the past year, ODM services, new-energy technology R&D, and prior innovation recognition. Its lack of an available SDK is a limitation for SDK-supported development, but the broader evidence supports innovation capability.

Production capacityThe supplier is a factory with stated manufacturing activities covering batteries, mechanical and electrical equipment, testing machines, and graphite/carbon products. Hydrogen water bottle output is stated at 8,000–20,000 units annually, and reported lead time is within 15 working days in both peak and off-season periods.

Customization capabilityThe supplier explicitly offers customization from designs, customization from samples, full customization, and minor customization, in addition to ODM services. This is direct evidence of broad product customization capability.

Client casesThe supplier reports OEM service for well-known brands and participation in the Korea Hydrogen Energy Exhibition. Its company description also records technology-project selection and industry recognition, but no specific customer names or detailed delivery cases are provided.

Product Q&A

Q:What is the response time for HiCaP100?

HiCaP100 delivers a fast response time of less than 2 seconds for H2, CO, and combustible gas sensors, which is 3x faster than standard platinum black.

Q:How stable is the signal output over time?

The catalyst ensures long-term stability with signal drift of less than 3% over more than 24 months, thanks to its low chloride content (<0.2%) and anti-agglomeration particles.

Q:What is the purity of the platinum black?

HiCaP100 is a high-purity catalyst with greater than 95wt.% Pt purity, confirmed by well-defined XRD peaks and highly ordered crystallinity.

Q:Can the particle size be customized?

Yes, customization is available. The particle size can be tuned between 4-10nm, and slurry formulation can be optimized to fit specific sensor designs.

Q:What are the sample options and delivery time?

Lab samples of 1g, 5g, and 100g are available with fast delivery within 3-5 days, allowing for small-scale testing with low risk.
