  PROFILE

  新着情報

Marusan Electronics is a specialist manufacturer of industrial heat sinks founded in 1963. LEX heat sinks feature high precision and efficiency, and we ensure complete quality management both for our catalogue items and custom-made items: quality management right from design and development, to the acceptance of raw materials, to precision processing, surface finishing, detailed inspection, through to packing and shipping.

We have acquired international standard certification in the form of both quality and environmental ISO certificates.

In addition, in recent years we have reinforced our services, including assembly services, based on the catch call of “one-stop support.” Moreover, we provide further value-added with our thermal analysis, using special thermal analysis software and real-time measurements.

LEX MARUSAN is a heat countermeasures brand you can trust for both quality and environmental friendliness.
