Heat that regulates
itself.
PTCWORKS designs and manufactures PTC ceramic heaters for industrial, automotive and consumer OEM programs — engineered for stable resistance-temperature performance and tight batch consistency.
Self-Regulating Response
Resistance stays low until the Curie point, then rises sharply — limiting current automatically without external controls.

Factory-direct PTC
manufacturing.
From material formulation to finished heater assemblies, we support customers through sampling, certification and mass production.
PTCWORKS was founded in 1993 and is recognized as a National High-Tech Enterprise in China. Built on 30+ years of process experience, our team focuses on stable resistance-temperature performance, tight batch consistency, and fast turnaround for OEM/ODM projects.
With strong in-house R&D and 20+ national patents in PTC technology, we support customers through every stage of development — sampling, certification and mass production — with the responsiveness of a factory-direct partner rather than a trading company.
