Hot Runner Systems are heating component systems used in injection molds to inject molten plastic particles into the cavity of the mold. Since 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. Hot runner uses heating to ensure that the plastic in the runner and gate remains molten. Since there are heating rods and heating rings near or in the center of the runner, the entire runner from the nozzle outlet of the injection molding machine to the gate is in a high temperature state, keeping the plastic in the runner molten. There is generally no need to open the runner to take out the condensate after shutdown. When you turn on the machine, you only need to heat the flow channel to the required temperature. For this reason, the hot runner process is sometimes called a hot manifold system, or runnerless molding. Hot runner systems are divided into adiabatic runner (fully hot runner) and micro semi-hot runner system (semi hot runner). Hot runner systems generally consist of hot nozzles, manifolds, temperature control boxes and accessories.
