What is a hot runner? | Milacron Blog
A hot runner system is a molten plastic conveying unit used within an injection mold. In other words, a hot runner system consists of heated components (generally via electricity) used inside the plastic injection molds, which brings the molten plastic from the barrel of an injection molding machine into the cavities of the mold.
Use of Hot Runners Manifolds in Injection Molding
Wise use of a ‘Hot Runner’ mold strategy for appropriate part geometries can prove highly valuable for effective tooling and cost efficient molding. Manifolds, similar to hot runners, are also used to control temperature in injection molds and in the runner system.
Injection Molds: Hot Runner Vs. Cold Runner Molds | SIMTEC
Aug 07, 2015· Often referred to as runnerless molding or hot-manifold systems, hot runner molds describe a set of temperature control heating-devices installed in the mold. The purpose of a hot runner injection system is to maintain a molten flow of plastics or rubber from the injection molding machine nozzle to the gate in a plastic injection mold …

Hot runner system for injection mold – plasticmoulds.net
Hot runner system can be seen as an extension of injection molding machinery. The function of the hot runner system is to thermally insulated to send the thermoplastic melt to the plastic mold.. The hot runner can be heated independently while it is thermally insulated in the injection mold, which can compensate for heat loss caused by contact with the “cold” mold surface.
