Following are a few of the applications for which high conductivity copper alloys are a good material choice to consider:

Plastic injection molds, cores and cavities, core pins and chill plates.
Dies used in the extrusion of complex plastic profiles and shapes. The use of high conductivity copper alloys here results in productivity gains from their rapid heat transfer and dimensional stability.

  Blow molds for the production of bottles. High conductivity cop-per alloy inserts in the mold—par-ticularly at the base of the bottle and around the neck—will result in the optimum manufacturing productivity and component quality.

  Injection nozzles. When high conductivity copper alloys are used, an even temperature is maintained that will result in a far simpler overall control system due to the rapid heat transfer time and reduced energy costs. Product-Specific Examples

  Plastic Bin Production
Plastic bin manufacturers are using molds containing high conductivity copper alloys and depending on the level of desired performance, some manufacturers use beryllium copper alloys for the cores and cavities. However, where work shop practices exclude beryllium-containing alloys from being used, a beryllium-free alloy is the material of choice.

   Plastic Caps Production
Plastic mineral water bottle closures, in the form of plastic caps are produced with considerable success using high conductivity copper alloys cores and cavities. Oftentimes 0.5 percent BeCuCo alloys are used—dependent upon which polymer is being molded—with an electroless nickel coating.

Again, the sensitivity toward using beryllium alloys has resulted in the development of highly effective, beryllium-free alternatives.

 Automotive Production
The automobile industry has introduced aluminium bronze inserts into their steel molds for the production of bumpers, where others even use complete high conductivity copper alloy cores for their bumpers production.

Dashboards for automobiles are also produced with molds containing aluminium bronze inserts, thus increasing the heat conductivity by three times compared to the steel used in production.
