AI-Powered supplier vetting

SummaryThermal International Co., Ltd. is identified as a private manufacturer/factory in Shenzhen, China, specializing in home-appliance heating elements, thermostats, switches, and motors. The supplier reports ISO 9001 certification, six production lines in one operational record, and a separate company description claiming ten assembly lines across three owned factories. It reports 11–20 R&D engineers, 11–20 quality-control staff, and product output information for hot plates, heating elements, and thermostats. Export activity began in 2008, with 51%–70% of total sales from exports and self-operated import/export rights. The supplier states that it supports on-site and third-party inspections, pre-sales consultation, timely delivery, and after-sales service. However, several areas—including outsourcing procedures, inventory, overseas operations, OEM/ODM, SDK-related R&D, quality traceability, customer cases, and current audit validity—remain unverified or explicitly unknown.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory, with a stated factory location in Shenzhen, China. Its reported production infrastructure includes six production lines in one record, while another description claims ten assembly lines across three owned factories, so the exact consolidated factory footprint is inconsistent but manufacturing status is clear.

CertificationsThe supplier reports ISO 9001 certification for its management system. This is explicit evidence of certification holding, although no certificate number, scope, or validity period is provided.

After-Sales capabilityThe supplier states that it provides personalized service from pre-sales consultation through after-sales service, with a sales team offering professional advice and timely delivery. These statements support the existence of an after-sales service commitment, although no service-level details or performance evidence are supplied.

Production capacityThe supplier reports six production lines in one factory record, while its company description states ten assembly lines across three owned factories. It also provides product-specific output quantities for hot plates, heating elements, and thermostats, which explicitly supports established production capacity, although the differing line counts should be clarified.

Product Q&A

Q:What is the standard thread specification?

The standard thread specification is DN25 (1-inch BSPP Imperial Pipe Thread). Other standards like G1 or NPT1 can be customized.

Q:Can the voltage and power be customized?

Yes, the product supports full customization. Standard voltage is AC 220V 50Hz, but 110V/120V and 380V are available. Power ranges from 1.5kW to 12kW depending on tank volume.

Q:What material is used for the heating sheath?

The standard sheath material is food-grade SUS304 stainless steel. It can be upgraded to SUS316L or titanium for stronger corrosion resistance.

Q:Is the product safe for drinking water?

Yes, the food-grade SUS304 stainless steel sheath meets drinking water heating safety standards, is corrosion-resistant, and does not leach heavy metals.
