About Hot Runner Mold
-Development History
The production of hot runner molds is extremely active in industrialized countries and regions around the world. The proportion of hot runner molds is constantly increasing. Many small mold factories with less than 10 people produce hot runner molds. Overall, North America and Europe have been using hot runner technology for a long time and have a higher level of experience. In Asia, except Japan, Singapore, South Korea, Taiwan, China and Hong Kong are in the lead. Although the level of mold manufacturing is relatively high in North America and Europe, the prices are higher and the delivery time is longer. In contrast, Asian hot runner mold manufacturers are more competitive in terms of price and delivery time. The hot runner mold in Chinese Mainland is still in its infancy, but it is growing rapidly and the proportion is increasing.-Structure
The hot runner system generally consists of several parts, including a hot nozzle, a splitter plate, a temperature control box, and accessories. There are generally two types of thermal nozzles: open type and needle valve type. Due to the fact that the form of the hot nozzle directly determines the selection of the hot runner system and the manufacturing of the mold, the hot runner system is often divided into an open hot runner system and a needle valve hot runner system accordingly. The splitter plate is used when the first mock examination has multiple cavities or multi-point feeding, single point feeding, but the material level is offset. The material is usually P20 or H13. The splitter plate is generally divided into two categories: standard and non-standard, and its structural form is mainly determined by the distribution of the cavity on the mold, nozzle arrangement, and gate position. The temperature control box includes the host, cables, connectors, and wiring male and female sockets. Hot runner accessories typically include heaters and thermocouples, runner sealing rings, connectors, and junction boxes.
