The hot runner mold refers to a mold that uses a heating device to keep the melt in the flow passage from solidifying at all times. Because it is shorter than the traditional mold shot cycle and saves raw materials, hot runner molds are widely used in various industrialized countries and regions in the world today. Shorten cycle The molding cycle is shortened. Because there is no restriction on the cooling time of the sprue system, the parts can be ejected in time after curing. Many thin-walled parts produced with hot runner molds have a molding cycle of less than 5 seconds. Save material In the pure hot runner mold, there is no cold runner, so there is no production material. This is especially significant for applications where plastics are expensive. In fact, the major hot runner manufacturers in the world have experienced rapid development in the world when oil and plastic materials are expensive. Because hot runner technology is an effective way to reduce material costs. Red...
