Premium PTC Thermistors & PTC Heaters: Solutions from a 30-Year PTC Heating Element Factory

We are a benchmark PTC heating element factory with 30 years of specialized expertise in developing, manufacturing, and supplying high-performance PTC thermistors and PTC heaters. Established in 1991 (restructured from Weihai Huancui Electronic Materials Factory), our PTC heating element factory is one of China's earliest manufacturers dedicated to PTC technology, and we now deliver comprehensive PTC solutions to global clients.

As a professional PTC heating element factory, we center our offerings on PTC thermistors-the core semiconductor components with positive temperature coefficient properties. A PTC thermistor excels in temperature control, overcurrent protection, and heating scenarios, and our PTC heating element factory produces PTC thermistors with rigorous quality checks: Each PTC thermistor undergoes multi-stage testing to ensure stable resistance, precise temperature response, and long-term durability. These PTC thermistors serve as the foundational core of our PTC heaters, enabling the safe, efficient, and self-limiting heating performance that defines our products.

Our PTC heating element factory designs and produces a diverse range of PTC heaters integrated with our premium PTC thermistors. As a trusted PTC heating element factory, we engineer each PTC heater to adapt to specific application needs: Whether for new energy vehicles, household appliances, or industrial equipment, our PTC heaters deliver consistent heating while leveraging the PTC thermistor's inherent temperature-limiting capability. Every PTC heater from our PTC heating element factory is manufactured via automated production lines (including compacting equipment, automatic aluminum spraying production lines, and testing systems), ensuring uniform quality across batches.

A key advantage of our PTC heating element factory is full customization for both PTC thermistors and PTC heaters. For PTC thermistors, we tailor critical parameters like resistance range, electrode processes, and operating temperature to your specifications. For PTC heaters, we customize product dimensions, rated voltage, surface temperature, and heating power-ensuring our PTC products align perfectly with your device's design and performance requirements. This flexible customization is a cornerstone of our PTC heating element factory's client-centric approach.

Our PTC heating element factory operates a 15, 000 Square Meters production base (with 3 standard workshops) and achieves an annual output of 180 million PTC thermistors and PTC heaters-capable of meeting large-volume order demands. To guarantee quality, our PTC heating element factory holds authoritative certifications (IATF 16949, ISO 9001, SGS, ABS) and implements full-cycle strict quality inspection (pre-production to post-production), resulting in a 99.9% yield rate for our PTC thermistors and PTC heaters.

The PTC thermistors and PTC heaters from our PTC heating element factory serve a wide range of industries: New energy vehicle heating systems, electric mosquito repellents, electric foot baths, electric shoe dryers, humidifiers, air conditioners, fans, electric kettles, and bathroom radiators, among others. 80% of our PTC products directly or indirectly partner with major global brands (including Changhong, Hisense, and top NEV manufacturers)-a testament to our PTC thermistor and PTC heater reliability.

Backed by 7*24h one-to-one service, our PTC heating element factory invites you to conduct on-site audits and discuss cooperation. Let our 30 years of expertise deliver tailored PTC thermistor and PTC heater solutions that meet your exact needs.
