With the increasing promotion and application of hot runner technology, the proportion of hot runner molds will gradually increase. Hot runner technology can improve the production efficiency and quality of parts, and can significantly save raw materials for parts. With the continuous increase in labor and plastic raw material costs, if the hot runner can be standardized according to the field of use and no longer customized one-on-one, the design and manufacturing costs of the hot runner will be greatly reduced, and users can be very skilled in using it. Just like using standard mold parts, it can not only shorten the mold manufacturing cycle, but also improve mold quality and reduce mold manufacturing costs. Hot runners will also be widely used, bringing the greatest benefits to users. At the same time, the market also needs to eliminate some thermal runner companies with poor technology and no scale effects, which will be the trend of the development of thermal runner companies in the future.
