Molders that are having their molds built with copper alloys to take advantage of increased mold cooling discovered that copper alloys are easily damaged. When copper alloys are formulated to resist wear, thermal conductivity can be significantly reduced. Molders then were forced to choose between fast cycle times due to increased mold cooling or better wear resistance. Molders that are using copper alloys successfully in molds have learned that float mould components may be the most successful mold design concept to minimize wear. Floating mold components therefore allow the molder to have minimal wear and fast cycle times.
