Cold Runner Vs. Hot Runner Molding Systems - Key

Jul 17, 2014 · Cold-Runner Mold Systems. Called a cold-runner mold system because the runners are the same temperature as the molds, there are two types of cold-runner systems: a three-plate system and a two-plate system.. Three-plate systems allow the part to be ejected from the runner without an ejection system, but are a little more complicated than a two-plate system, which does require an

An Introduction to Hot Runner Systems in Injection Molding

It is an injection molding assembly that uses a heated manifold to keep plastic in a molten state. This heated plastic travels from the molding machine nozzle through internal channels called runners and can be delivered directly into multiple cavities at the same time. Hot runner vs cold runner injection molding systems

Choosing Between Cold and Hot Runner Systems |

Nov 01, 2017 · The injection molding industry generally perceives companies that use hot runner systems as more advanced than companies that use cold runner systems. Often, shops make the decision to use a hot runner without considering a cold runners possible cost and quality benefits, or management dictates the decision as part of a cost-savings initiative.

Hot & Cold Runners For Injection Molding

You can contrast the term hot runner with its opposite, and the historically more common cold runner. Cold runners are simply an unheated, physical channel that is used to direct molten plastic into a mold tool cavity after it leaves the nozzle. The primary difference is that hot runners are heated while cold runners are not. While hot runners are not required for injection molding processes, they can

Hot Runner vs Cold Runner Injection Mold | Injection Mold

Runner is a channel inside the injection mold that guides the molten plastic from injection molding machine barrel to the mold Cavity. Depending on the type of runner system, the runner keeps in molten state or gets solidified along with injection molded parts.Here are the two types of injection molds according to the feeding system:
