Packaging industry


Cast Heaters are suitable for food industry machinery and pharmaceutical facilities. They are used for sealing and welding with and without coating. Based on uniform heat distribution, high precision of contact surfaces, reaction fast temperature ranges and shape stability due to special aging procedures perfect operating conditions and long life time is guaranteed.
