AI-Powered supplier vetting

SummaryThe provided information presents Guangdong Ruiji Precision Electronics Co., Ltd as a China-based manufacturer/factory in Dongguan, Guangdong, established in 2009 and focused on PTC heaters, PTC thermistors, NTC thermistors, NTC sensors, and heating elements. It reports ISO 9001 certification, RoHS compliance, 6–10 R&D engineers, 6–10 quality-control staff, eight production lines, and nearly 100 million units of annual production capacity. The company states that it provides OEM/ODM services and serves customers in consumer electronics, household appliances, automotive, industrial equipment, HVAC, and related sectors. Export sales are reported at 51%–70%, with exporting since 2009. However, the slices contain inconsistent supplier identities: several records concern Guangdong Ruiji, while others identify Dongguan Tianrui Electronics Co., Ltd. This discrepancy should be resolved before relying on the combined capability claims.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory, with activities covering research, development, production, and sales of PTC and related thermistor products. However, the records use both Guangdong Ruiji Precision Electronics Co., Ltd and Dongguan Tianrui Electronics Co., Ltd, creating an identity inconsistency that should be verified.

CertificationsThe supplier explicitly reports holding ISO 9001 certification, and its products are stated to be RoHS compliant. These are direct positive indicators of documented quality management and product-compliance practices, although the specific scope, issuing body, and validity period are not provided.

R&D capabilityThe company is described as focusing on research and development, continuous improvement, and innovation, with 6–10 R&D engineers. It also reports eight automated assembly lines, which supports process modernization, but there is no evidence of patents, dedicated laboratories, new-product records, or quantified R&D results.

Production capacityReported production resources include eight production lines, eight automated assembly lines, 6–10 quality-control staff, and nearly 100 million units of annual capacity across a 5,000-square-meter facility. These explicit figures support substantial manufacturing capability, although the slices do not clarify whether all figures belong to the same legal entity because of the Ruiji/Tianrui identity inconsistency.

Customization capabilityThe supplier explicitly states that it provides OEM/ODM services, directly supporting the ability to undertake customer-specific product or manufacturing requirements. No details are provided on customization scope, engineering workflow, tooling, minimum order quantities, or development lead times.

Product Q&A

Q:What is a PTC heater and how does it work?

A PTC heater uses Positive Temperature Coefficient ceramic elements. As temperature rises, electrical resistance increases, reducing current flow. This self-regulating feature prevents overheating and maintains consistent temperature without additional controls.

Q:What are the main components of a PTC heater?

A typical PTC heater consists of a PTC thermistor (core heating component), terminals, insulating materials, and a casing. The thermistor generates heat, while the casing and insulation provide safety and protection.

Q:Is the wire length customizable?

Yes, the wire length is customizable. We offer various connectors and wires upon request to suit your specific application needs.

Q:What is the delivery time for orders?

If goods are in stock, delivery is generally 3 days. If not in stock, it takes 5-10 days depending on the quantity. Peak and off-season lead times are within 15 workdays.

Q:Do you provide free samples?

Yes, we can offer samples for free charge. However, the customer needs to pay for the freight cost.
