Four Benefits Of A Hot Runner System For Injection Molds

In any plastic injection mold the cycle time is largely determined by the thickness of the part. In many cold runner systems, the runner thickness exceeds that of the molded part, slowing things down dramatically. When the cold runner is eliminated, the cooling time is reduced by the difference in the cooling time of the […]
