PSG Plastic Service Group said two new models of hot-runner controllers, the Temp-command series and HRD series, feature a diagnostic system that protects against errors in the wiring of connecting cables and hot runners, along with failures in components of heaters and sensors.
The mold-check function protects the hot-runner system, according PSG of Stevensville, Mich.
Temp-command controllers can come pre-wired for startup, or supplied in a special housing capable of controlling up to 256 zones. HRD controllers come in versions with from six to 30 control zones, packaged in a compact table housing.
