What is a hot runner mold?

A hot runner system is an assembly of heated components used in plastic injection moulds that inject molten plastic into the cavities of the mould. (The cavities are the part of the mould shaped like the parts to be produced.) … A hot runner system usually includes a heated manifold and a number of heated nozzles.

Hot Runner Molds: Speed at a Price

Hot runners exist for one reason: once the plastic has filled the mold cavity and cooled, it has been filled the runners. If left alone, it will cool as well and be ejected along with the part (depending on the mold type, they either remain attached to the part or are separated before ejection). Heated runners make use of a heated manifold that keeps the plastic in the runners molten, which has some significant advantages and disadvantages.

Hot Runner Advantages

Eliminates waste plastic because the runner plastic doesn’t need to be ejected with the part. Have plastic ready to go in the runners leads to faster cycle times and higher part volume. Without the resistance of the cooling plastic in the runners, less pressure is needed. Without having to worry about plastic cooling in the runners, moulds can make larger parts.
