Controls

Milacron’s Mosaic Microprocessor Control System

The Mosaic Microprocessor Control System puts state-of-the-art automation on your extrusion floor.

Our innovative “Mosaic” software has proven to be fast and intuitive. The fifteen-inch, full-color, touch-screen is provided in English and with the touch of a button, can be changed to an optional alternative language.

The B&R APC620 control hardware is a proven performer and is backed by worldwide sales and parts support. The program is stored on a rugged and reliable compact flash card eliminating the need for a hard drive. Your program can be archived on a second compact flash card so you will never have down time due to a lost program. Fast boot-up time means that you start production quickly.

Well-designed screens allow your operators to easily monitor and adjust all temperature set points. Self-tuning PID algorithms make fluctuating temperature control a thing of the past.

The keyboard is dust & liquid proof and has large pads to allow easy operation even while wearing gloves. A high temperature rating and fully-sealed cabinetry is designed to keep you in operation in the harshest of environments.

Put today’s best extrusion control technology at your finger tips with Cincinnati Milacron’s Mosaic Control.

Die Temperature Setup Menu

Die Temps English

Used to establish the run and shutdown temperature setpoints for the die zones. This menu also displays the actual temperature of each zone. There may be as many as 10 temperature zones on this screen. Each zone can be turned ON or OFF.

Pre-Heat Menu

Preheat Page English

Used to set a time to enable the control to turn ON the Heat Control Master on the Extruder Temperatures or Die Temperatures menus.

Trending Menu

Trend

Can plot up to 4 selected items on the screen. Touch the carat at the right of the selection box. It will bring up a list of parameters to trend. Touch the parameter you wish to trend, and the screen will trend the parameter selected.
