Our services highlight the manufacture of ceramic emitters of infrared radiation, which has allowed us to launch onto the international market.

The infrared radiation ceramic resistors are suitable for molding plastics using the thermoforming process, due to its low cost and high durability. As a result, these ceramic resistors have become the most used in the fields of vacuum molding, blister-packaging manufacturing and automotive industry.
