What is hot runner?

The hot runner is heated to ensure that the plastics of the runners and gates remain molten. The hot runner system is generally composed of hot nozzles, manifolds, temperature control boxes and accessories. The hot nozzles generally include two types: open type. The hot nozzle and the needle valve type hot nozzle, because the hot nozzle form directly determines the hot runner system selection and the mold manufacturing, the hot runner system is often divided into an open hot runner system and a needle valve hot runner system.

Hot runner mold

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 forming cycle and saves raw materials, hot runner molds are widely used in various industrialized countries and regions in the world today.

Mold history

Hot runner mold production is extremely active in countries and regions with more developed industries in the world. The proportion of hot runner molds continues to increase. Many small mold factories with less than 10 people are producing hot runner molds. Generally speaking, in North America, Europe uses hot runner technology for a long time and has a high level of experience. In Asia, apart from Japan, Singapore, South Korea, Taiwan, and Hong Kong, China are in a leading position. In North America, Europe has a higher level of mold manufacturing, but the price is higher and the delivery time is longer. In contrast, hot runner mold manufacturers in Asia are more competitive in terms of price and delivery. The hot runner molds in mainland China are still in their infancy, but they are growing rapidly and the proportion is increasing.
