Hot Runner Molds In a three-plate mold, the runner system must be reground and the material reused. However, it is possible to eliminate the runner system entirely by keeping the material fluid. This is done by using a hot runner mold (Fig. 6-3). The material is kept plasticized by the hot runner manifold, which is heated with electric cartridges. The block is thermostatically controlled, and heated probes, controlled by thermocouples and pyrometers, are used. The material is kept fluid at the proper temperature, and the injection pressure is transmitted through the hot runner manifold and gate into the part. A probe is inserted from the runner to the gate area. There are two kinds of probes: one has no moving parts and essentially depends on the insulating properties of the plastic at the gate area to prevent it from drooling, whereas the other has a reciprocating device or other method to block the flow between each shot. A hot runner mold is more difficult to start up than a three-plate mold. It takes considerably longer to become operational. In multicavity molds, balancing the gate and the flow and preventing drooling can be difficult. The hot runner mold is highly susceptible to tramp metal, wood, paper, and other contaminants, which quickly clog up the nozzle. Various screen systems have been devised in attempts to prevent this. Cleaning out a plugged hot runner mold is a long process, and the molds themselves are relatively expensive; but they offer the advantage that in a long-running job, they provide the most economical way of molding. There is no regrinding, with its cost of handling and loss of material. The mold runs automatically, eliminating the variations caused by operators. The loss of temperature and pressure experienced with a cold runner in a threeplate mold is eliminated.
