Control Retrofits for Injection Molding & Structural Foam Machines
The industry standard MACO Alpha series (MACO 40, 400, 4000 & 4500 by Barber Colman / Eurotherm) has been faithfully serving the injection molding industry since 1992. The MACO Alpha has been credited with world class injection & temperature control algorithms.
The 640 x 480 10.4″ display offers greater resolution than the preceding Barber Colman MACO 8000 and allows more information to be displayed on each screen (page). This greater resolution allows fewer total screens that operators and setup personnel need. This reduction in total screen number allows quicker setup of different part runs. The display comes with a standard cartridge port & an optional floppy disk, as well as internal memory, that allow storage of several different product recipes. Six quick access membrane screen path buttons (located just below the display screen) help to make screen pathing simplified. There is also a “Go to Screen” feature that allows operators to enter the desired screen number and immediately be pathed to that specific screen.
There are 4 security levels. Each screen has a security level programmed. Each setpoint on the screen also has an independent security level. The screens can be programmed to allow complete viewing and changing of setpoints/swtitches, viewing only of setpoint/switches or no access to each individual screen. Each security level
has the capability of up to 40 unique user identification codes. Each operator can login under an individual user ID and the changes that an operator makes, to any setpoint on any screen, is automatically logged into a Setpoint Change Log screen. The Setpoint Change Log screen date & time stamps the changed setpoint. The original value and the new value of the setpoint is also logged. These changes are also stamped with the operators actual ID number. This helps identify possible reasons for process variations that otherwise might go undetected.
Statistical Process Control (SPC) is an available option. This feature allows for up to 10 different process values or setpoints to be logged
on a selectable time interval. Each parameter can be either time or event based triggered. Sample size , time between readings, time between sample groups, upper & lower specified limits are user selectable. X-Bar, Range, and Histogram charts are displayed for each vaue. Standard calculations such as X-Bar, X-Bar-Bar, Range & Cpk are automatic & readily available.
Control rack configurations can have either 7, 9, 12 or 16 slots for machine control inputs & outputs. These optional rack sizes allow the system to be tailored to the machine’s I/O requirements. Up to 3 control racks can be networked for additional I/O requirements. The 9, 12 & 16 slot rack power supply is a switching power supply that has built in voltage filtering and can accept AC voltages ranging from 85 VAC to 265VAC and 47 to 63 Hz (Note that the 7 slot rack power supply is a 24VDC supply).

The Eurotherm / Barber Colman MACO Compact is a cost competitive general-purpose programmable logic controller with the advantages of integrated, total machine control in a compact package. It is an expandable system, similar to the industry standard Eurotherm / Barber Colman MACO 4000, but designed for lower cost without sacrificing high-tech performance.
The Eurotherm / Barber Colman MACO Compact supports either open or closed loop (IMPACT™ II) injection process control. Run the machine for a few cycles, and IMPACT II creates a theoretical model of the process. It uses this model along with hundreds of rules to automatically optimize the process to compensate for short and long term deviations in the injection molding process.
Precise adaptive automatic tuning is included for temperature control. SPC calculations and charts can be viewed on Eurotherm’s new line of OPtima CE touch screen displays.
