Incorporating film heaters
into automotive exterior plastic components
Anti-fogging and de-icing heaters
to maintain the functionality of LiDAR and Sensors
Wire-embedded film heaters
• Wire-pattern design that ensures radio-wave transparency
• One-stop processing that includes incorporation into molded products
• Ability to accommodate IMD/IML (in-mold decoration)
We can propose designs for customers.
Product form that allows for development
– Heater and decorative film
– Heater and decorative film and molded component
Data from defrosting testing
Sample configuration
Formation of heater (wire) on top of PC film
Sample size of 70 × 50 mm
Evaluation of heating characteristics from PC film side
Electrical characteristics and heating characteristics
When 3 V is applied in a room-temperature environment, the temperature of the surface 120 seconds later undergoes a change of +30.8 °C.
This heating performance melts snow and frost in cold regions.
At the same time that the power of the heater is turned on, the temperature of the wire portion rises, and defrosting fully takes place.
After 120 seconds, the temperature of the surface of the sample rises by approximately 20 °C.
Example of adoption
Front panel with wire heater for electric vehicle (EV)
A Nissha film-insert-molded product into which wire is embedded has been adopted for an EV front panel that is equipped with LiDAR.
We ask for customers to not hesitate to consult Nissha about the development and manufacture of film heaters.
