Walgren Controls
Walgren has extensive in-house capabilities, in both the US and Asia, for the engineering and
implementation of controls tailored to customers' individual product, process and throughput
requirements. Details. Walgren systems store process recipes on a PC; process control is through an
Allen Bradley, Siemens or General Electric PLC. All Walgren controls are NACAP and ISO compliant.
Walgren is well-respected for the development of documentation strategies that meet customer
and regulatory requirements, and are most useful to operations and management personnel for
response and resource planning. Graphing and statistical data is provided for all functions; rework
or scrap reporting is segmented by reason code and graphed for easiest comprehension.
Preventive maintenance schedules and alerts are programmed at the time of commissioning,
and can be adjusted by operations management.
In addition to its in-house capabilities, Walgren's controls partner is Aucos, the world's
preeminent automation company specializing in controls for anodizing, plating and specialty
finishing systems.
Aucos has more than 50 specialists dedicated exclusively to the design and development of
hardware and software solutions that meet the specific needs of metal and plastic finishers.
The exceptional adaptability of Aucos hardware and software today benefits more than
1000 production sites in North and South America, Europe and Asia.
The Aucos partnership allows Walgren to most effectively meet clients' unique needs for speed,
flexibility and documentation. Of particular interest to Walgren customers are these recent
developments:
- Two important hoist control solutions are "fixed timeway" and "optimizing" software.
In addition, the Aucos "optimizing" or "random loading" system is state-of-the-art. All Walgren
software solutions are compatible with major SPC programs.
- Walgren also offers wireless hoists, an important development that eliminates cables for
power and signals, reduces noise and extends conventional hoist ranges.
- Walgren hoist control can now be via a handheld terminal with a built-in 2D barcode scanner.
The terminal provides real-time access by WLAN for tank lines, hoists rectifiers and more.
- Reservation-based scheduling software can be provided for greatest line productivity.
- Walgren offers a Windows version of the control system for electroplating.
This is based on a standard PC systems and is already running on small computers.
Because all of the programs have been implemented in the Windows control system, it can be
used with every type of finishing operation. With the aid of advanced simulation, processes can be
evaluated in great detail, adding an important measure of predictability, and often streamlining
lead times for production start-up.
