AI-Powered supplier vetting

SummaryTaizhou Mingjia is a limited company manufacturing and selling switches and thermostats, with 23 production lines, automatic and assembly lines, inventory capability, and export activity. Its thermostat and switch operations are stated to hold ISO9001:2015 quality management certification, while CE and UL certifications are also identified. The supplier demonstrates broad customization, ODM, and OEM capabilities, including new product development during the past year. Documented procedures exist for corrective actions, customer complaints, supplier assessment, and finished-product inspection. However, quality inspection staffing is limited to one inspector, there is no valid manufacturing-capacity contract with related subcontractors, and no standard outsourcing procedure or ongoing batch quantity reconciliation is reported. Overseas warehouse and showroom capabilities, SDK availability, and customer-specific case details are not evidenced.

Supplier typeThe supplier is identified as a limited company with a combined company type. Its stated business scope covers manufacturing and sales of switches and temperature controllers, plus import and export of goods and technology, and its offered products are switches and thermostats.

CertificationsThe company states that its thermostat and switch operations have ISO9001:2015 quality management system certification. The provided information also lists CE and UL product certification capability, supporting a positive certification assessment.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, as well as written supplier-service assessment procedures. It has inventory capability, but no overseas warehouse or showroom; the evidence supports service-process capability rather than full overseas service coverage.

R&D capabilityThe supplier reports new products during the past year and offers ODM services, indicating active product development. It does not have an available SDK, but SDK availability is not sufficient by itself to negate the evidenced R&D and ODM capability.

Production capacityProduction evidence includes 23 production lines, automatic and assembly lines, inventory capability, and finished-product inspection instructions that are uniformly followed. Risks remain because there is no valid manufacturing-capacity contract with related subcontractors, no outsourcing SOP, and no ongoing batch quantity reconciliation.

Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, and flexible customization. These capabilities are stated consistently across the R&D and design-service information, supporting a strong customization assessment.

Client casesThe company description states that many customers regard it as a high-quality supplier, and the supplier reports providing OEM services for well-known brands. No specific customer names, projects, order results, or case details are supplied.

Product Q&A

Q:The terminals look different from standard models. What are the connection options?

Yes, because this model handles high currents, it features widened brass terminals with screw holes or heavy-duty rivets for a secure, low-resistance connection. We can customize the terminal angles and the mounting bracket style to fit your specific housing design.

Q:Can this Bakelite (plastic body) thermostat withstand high temperatures?

Yes, absolutely. The black base is made of high-grade Bakelite (phenolic resin), which offers excellent electrical insulation and can safely operate in ambient temperatures up to 180C without deformation. For applications exceeding this range, we also offer a ceramic body alternative.

Q:Is this big-current switch suitable for commercial water heaters and boilers?

Yes, it is widely used for that exact purpose. Due to its high current capacity and snap-action reliability, it is ideal for commercial/industrial water heaters, fast-heating boilers, steam cleaners, and large kitchen appliances as a reliable temperature control or secondary over-temperature safety cut-out.
