Engineering heat control since 1993.
PTCWORKS designs and manufactures PTC ceramic heating elements for industrial, automotive and consumer OEM programs. Three decades in, we’re still a factory-direct partner — not a trading company — for buyers who need certifiable quality at scale.
Three decades of
PTC manufacturing.
From a specialist workshop to a certified OEM/ODM supplier serving industrial, automotive and consumer programs worldwide.
PTCWORKS was founded in 1993 and has spent over 30 years focused on a single material system: PTC ceramics. That focus is recognized formally — we hold National High-Tech Enterprise status in China — and practically, in the batch-to-batch consistency our customers see when they scale a program from sample to mass production.
With 20+ patents in PTC technology and in-house R&D, we don’t just manufacture to a customer’s drawing — we help OEM and industrial buyers choose the right heater architecture (liquid, air, cased or chip) for their application before tooling ever starts.

PTCWORKS launched
International brand established for global OEM/ODM buyers.
Three commitments
to every order.
The same standard whether it’s a 50-piece sample run or a 500,000-unit program.
Engineering Rigor
Every heater is specified against a target resistance-temperature curve, not just a wattage — so performance is predictable, not just “close enough.”
Batch Repeatability
Tight process control means the 10,000th unit performs the same as the 1st — critical for OEM programs that can’t tolerate drift.
Factory-Direct Access
You talk to the people building your product, not a sales layer — faster answers on tooling, lead time and spec changes.
What we build,
in-house.
Three heating methods, covering liquid, air and direct-contact applications.
- Liquid HeatingFlow-through, immersion, bottom-mounted and pipe-jacket PTC elements for water and coolant systems.
- Air HeatingForced-air and convection PTC modules for HVAC, drying and defrost applications.
- Conduction HeatingCased heaters (ceramic, plastic, aluminum, resin-encapsulated housings) and heating chips for direct-contact thermal transfer.
