Hot runner system is often used in our mold design. It is used more frequently in our NJPE company. The hot runner system is divided into hot runner ( fully hot runner)And a miniature semi-hot runner system (semi hot runner). The design of the hot runner is complicated, but the effect is good and the maintenance cost is very low. The micro semi-hot runner is simple in structure, stable and easy to use, low in failure rate, low in maintenance cost due to simple structure, and has greater guarantee for stable production. The hot runner mold is a mold that uses a heating device to make the melt in the runner not solidify all the time. Because it is shorter than the traditional mold forming cycle and saves more raw materials, hot runner molds are widely used in today's world's industrialized countries and regions. Hot runner is divided into open type (For miniature semi-hot runner)Needle valve type (For hot runner). Hot runner system is generally composed of hot nozzle, Splitter plate, temperature control box and accessories. Hot nozzles generally include two types: Open hot nozzles and needle valve hot runner systems. The splitter plate is used in one-mode multi-cavity or multi-point feeding and single-point feeding but the material level is biased. The material is usually P20 or h13. Splitter plates are generally divided into standard and non-standard categories. Their structural forms are mainly determined by the distribution of cavities on the mold, the arrangement of nozzles and the position of glue ports. The temperature control box includes the main machine, cables, connectors, male and female sockets for wiring, etc. First, the advantages of hot runner 1 shorten the forming cycle of the parts because there is no restriction on the cooling time of the runner system, the parts can be ejected in time after forming and curing. Many thin-walled parts produced by hot runner molds can have a molding cycle of 5 seconds. 2, save plastic raw materials in the pure hot runner mold production because there is no cold runner, so there is no production cost. This is especially significant for expensive plastic applications. In fact, major hot runner manufacturers in the world have developed rapidly in the world when oil and plastic raw materials were expensive. Because hot runner technology is an effective way to reduce material costs. 3 eliminate subsequent processes, which is conducive to production automation. The finished part is finished after being made and formed by the hot runner mold, and there is no need to trim the gate and recycle the cold runner. Conducive to production automation. Many foreign product manufacturers have combined hot runner with automation to greatly improve production efficiency.
