The use of C17200 beryllium copper alloys in mold cores and cavities has been evaluated for effectiveness in meeting material requirements and minimizing per part cost. The alloys have been compared to tool steels and as well as aluminum alloys. It has been found that beryllium copper alloys are capable of producing significant per part cost reductions via their excellent thermal characteristics which allow for decreased cycle times, reducing part overhead, while maintaining good hardness, limiting the need for mold repair and refurbishment.
Applications of Beryllium Copper Alloys for Injection Molding
Beryllium copper plate and rod wrought products are utilized in the plastics processing industry for plastic injection molds, blow molds, cavity inserts, and associated production components such as manifolds and nozzles. The material is specified in these applications due to it combination of high strength and hardness coupled with excellent thermal conductivity (as compared to tool steel and aluminum). The material performance properties of beryllium copper provide the tangible benefits of improved cycle time and piece part quality with the assurance of ongoing superior wear and durability characteristics.
