Cast-in heater
A cast-in heater is a heater that is cast together with materials such as aluminum, iron, and brass, along with a sheath heater placed in a mold. It heats the heated parts with three-dimensional shapes, such as piping, valves, and molds, by covering them from the outside. It is mainly used in production lines for synthetic resins and synthetic fibers. Regardless of the shape, whether flat, cylindrical, or spherical, it efficiently supplies uniform heat to the metal surface. It is resistant to mechanical vibrations and impacts, making it a heater with a long expected lifespan.
