Hot Runner

From Wikipedia, the free encyclopedia

A hot runner is an injection mold component containing a series of channels that distributes molten plastic within a mold to increase molding productivity through reduced waste, as the runners arent wasted each cycle by being ejected, as the plasic stays molten and gets used on the next cycle.

"advantages" -less use of material -shorter cycle time -more choice where to put the injection place

"disadvantages" - die is more expensive -more chances of production process going wrong
