Glass mold temperature control is essential for consistent molding. Bottle machines utilize fans to distribute air over the molds to provide proper cooling. This quickly dispels heat to obtain economical production and evenly spreads the temperature across the mold to ensure product quality. The fans need to be designed to handle the strenuous environmental conditions of a glass factory. Twin City Fan builds fans for glass manufacturers across the world and has the capabilities to meet the stringent requirements of any customer. Typically these are HIB fans with monoblock bearings.
