What are the components of the hot runner?
Nov 12, 2018

The main components of the injection hot runner system include hot runner nozzles, hot runner heating elements, hot runner thermostats, hot runner manifolds and hot runner accessories (eg, temperature sensors and junction boxes).

Our common hot runner systems are available in single hot water ports and multi-point hot water ports. The single-point hot water port uses a single hot runner nozzle to directly spray molten plastic into the cavity. It is suitable for a single-cavity single nozzle plastic mold; the multi-point hot water port distributes the molten material to each hot runner through the hot runner manifold. The nozzle re-enters the cavity, which is suitable for single-chamber multi-point feed or multi-cavity molds.
