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:What temperature ranges do you offer, and can the capillary length be customized?

As a direct manufacturing factory, we offer a wide range of standard temperature scopes. Both the capillary tube length and the sensing bulb size can be fully customized according to your specific appliance design and space requirements.

Q:What types of appliances is this liquid expansion thermostat suitable for?

This heavy-duty mechanical thermostat is highly versatile and widely used in commercial and home kitchen appliances. It is ideal for electric ovens, water heaters, deep fryers, boilers, griddles, and other heating equipment that require precise, reliable temperature regulation.

Q:What is the operational lifespan of this thermostat, and how do you ensure quality?

Our thermostats feature a premium ceramic base and a robust mechanical structure engineered to endure over 100,000 operational cycles. We implement strict in-house QC testing on 100% of our products-including calibration and leakage checks before they leave the factory floor to ensure consistent batch quality.

Q:What is your Minimum Order Quantity (MOQ), and do you support private labeling (OEM)?

Yes, we fully support OEM and ODM services, including private labeling, logo stamping, and custom packaging. Since we are a direct factory operating mass production lines, our standard MOQ is generally 1,000 pieces per model. However, we can negotiate a smaller quantity for your initial trial order to kickstart our partnership.
