72 Drop Multi-material Stack Mould

Multi-material, multi-color hot runner system for a 3 shot over-molded part. With a combination of 6 manifolds connected via three bridging manifolds, the system had a total output of 72 drops (24 drops per component).
The system incorporated their popular MX13 and MX16 nozzle ranges and was controlled by back to back valve gates being fed by 3 separate injection points. Each injection point was controlled by individual valve pin shutoff to eliminate any drool at the sprue break.
The final completed part consisted of a 3 component over-mould part with TPE and LDPE material in a range of colours. The overall hot runner system weighed in at around 14 tonnes with an estimated total system weight of 35 tonnes.
