Cassette Spiral Resistors are high-performance heating elements designed in spiral shape, generally used in plastic injection molds and hot runner systems. Thanks to its spiral structure, it provides equal heat distribution to the surface and helps keep the mold temperature balanced. It operates reliably in harsh industrial conditions with its metal cassette body, high temperature resistance and compact design. It is widely preferred in the plastic, packaging and automotive industries with its energy efficiency, fast heating and long life features.
