JMMS Inc. showcased its hybrid tooling advances. According to the company, aluminum is becoming more popular for thermoplastic injection molds because it offers faster heat transfer and shorter cycle times than P20. It doesn’t match P20’s durability and maintenance specs, however, so JMMS engineers hybrid tooling with multiple alloys, including aluminum alloys like QC10. This hybrid tooling offers faster cycle times and lower development costs with the durability and reliability of P20 tooling, the company says.
The hybrid molds combine materials for specific performance and production characteristics, including aluminum inserts for faster heat transfer and shorter cycle times, and shut-offs made from MoldMax, a copper beryllium alloy with higher density than traditional tool steels, for improved thermal conductivity.
