Milacron Plastics Machinery, Batavia, Ohio, has introduced its Adaptive Process System (APS) for its Mold-Masters melt-delivery control technologies. The APS will now be used in Milacron’s entire core controls product line, including hot-runner and valve-gate controllers, E-Multi auxiliary injection units, and the new SmartMold monitor announced at NPE2015 (see July show report on hot runners and tooling).

The APS includes a number of proprietary technologies for adaptive auto-tuning heat control, as well as adaptive motor control with auto tuning for maintaining precise linear movement. Other features include short-circuit protection, automatic even heating to ensure proper thermal expansion, auto purge cycle, intelligent leak detection, and auto alarm for water flow based on flow, temperature, and pressure monitoring.

According to Milacron, the APS will help molders deal with challenges related to difficult engineering materials, high pressures, small shot sizes, high viscosity, and electrical environment variations.
