runnersystemer
Runnersystemer, often translated as "runner systems," are a crucial component in plastic injection molding. They are essentially the channels within the injection mold that guide molten plastic from the nozzle of the injection molding machine to the cavities where the final part is formed. The design and efficiency of the runner system directly impact the molding process, affecting cycle time, material waste, and the quality of the molded part.
There are two primary types of runner systems: cold runner systems and hot runner systems. Cold runner
The choice between a cold and hot runner system depends on various factors, including the type of
