MN Machinery Auto Trading supplies Electric Cartridge Heaters, designed for precise heating applications by insertion into metal blocks via drilled holes. These heaters are constructed using MgO powder or MgO tube, ceramic caps, NiCr 2080 resistance wire, high-temperature leads, and seamless stainless steel sheaths (304, 321, 316, 800, 840). Cartridge heaters are typically manufactured in high-density and low-density forms, depending on the industrial application.
High-density cartridge heaters are used for heating plastic injection molds, dies, and platens, while low-density heaters are suitable for packaging machinery, heat sealing, labeling machines, and hot stamping equipment. These heaters provide consistent and reliable heating performance, with maximum operating temperatures up to 870°C (1600°F) and a range of voltage options including 12V, 24V, 36V, 110V, 220V, 240V, and 380V.
