Heating Plates in Low Production Cost. Heating plates are mostly seen in home equipments and laboratory equipments that need continuous heating or source of heat like chocolate fountains. Many manufacturers prefer producing heating plates using aluminum alloy because this alloy has thermal properties that are suitable to play the role of heating plates. Many manufacturers also use die casting in producing heating plates because they find it more convenient and economical to use as compared to other processes.
In die casting, aluminum is melted by exposing to extremely high temperature. When the metal is already melted, it will be injected in molds or dies to take the shape of the parts. Afterward, when the metal is already solidified, the parts or casts in the dies will be removed and will be slightly polished. The parts are near net shape, meaning they are produced as whole parts so joints will be avoided. This makes the pressure die casting more efficient because it produces stronger and more durable products unlike other processes like extrusion. In extrusion, the products produced are in cross section making the parts less durable as compared to die casting. Aside from this, heating plates do not need hollow parts like that of what will be produced in extrusion. Lastly, pressure die casting is much inexpensive than extrusion that is why many manufacturers use die casting instead of extrusion.
