Industrial: Copper Alloy Molds

Copper Alloy Molds: The Plastic Industrys Best Kept Secret. The main function of an injection mold, beside defining a parts shape, is to remove heat from the plastic as quickly as possible. The mold should be thought of as a heat transfer device much like the automobile radiator shown above. The faster the mold can transfer heat out of the molten plastic and solidify it, the faster the mold

Article about applying cooper alloy on mold and molding

Copper alloys are attractive to the mold industry because of their high thermal conductivity, ease of machining by a variety of processes, and corrosion resistance to water, cooling fluids and the plastics being injected. Copper is the most thermally conductive of the common solids only silver, cubic boron nitride and diamond are more conductive.

Moldmax Copper Alloys EDRO

MoldMAX HH highhard is a highstrength beryllium copper mold alloy, made by Materion Brush Performance Alloys, for plastics molding appli ions. This alloy has a hardness and strength comparable with standard tool steels but its thermal conductivity is at four to six times higher. MoldMAX HH is used for injection mold cores and cavities and ...

Innovations : Copper Alloy Molds: Why Didnt Someone Tell ...

Copper Alloy Molds: Why Didnt Someone Tell Me Sooner Copper Appli ions in Innovative Technology. By Ralph Willett. As a manufacturer of injection molded parts, it might ch your attention if one of your colleagues suggested that decreasing your injection molding cycle time by 20 could be accomplished easily.

Industrial: Copper Alloy Molds Getting Heat Out of the Mold

AbstractIntroductionExperimental Design and ProcedureMoldEquipmentMeasurementFindingsConclusionsReferencesRemoving heat from complex areas of an injection mold is difficult and often remains unresolved in production tooling. Cycle times and/or dimensional stability are often sacrificed because of hot spots in the tool. This study investigated a variety of strategies employing copper alloys with and without water to the mold core. This study provided several surprises to the research team and identified one practical method for removing heat from nonwatered cores. Appli ion of high thermal conductivity copper allo
