Understanding the Value of Scientific Injection Mold Cooling

摘要

Many mold cooling layouts are only about 20-30% efficient, revealing severe deficiencies in the surface area in contact with the coolant (wetted surface) that determines the type, size and number of coolant passages; the dimensions between the edge of the channels and the part (edge-to-part or E2P), and between the edges of the cooling channels (edge-to-edge or E2E). In the past, and still today, significant losses in molding profit and reputation result from "guesstimated" mold cooling, an approach yielding approximation inaccuracies that become embedded in the tool steel, which likely turns the first molding trial into an autopsy instead of a trial run.
