The Maguire LineMaster Extrusion control system offers a simple and cost effective method for extrusion companies to automate the control of mono and co-extrusion lines.
The LineMaster range works to provide direct kg/h, gram per metre or micron control for mono and co-extrusion lines in Blown Film, Pipe & Profile, Wire & Cable, Sheet and Compounding.
The system utilizes a compact Loss in Weight (LIW) hopper that monitors materials consumption live and updates this information every second.
Coupled with the LIW hopper LineMaster has 4 different control packages designed for different requirements of extrusion processes. These range from providing simple kg/h control of an extruder, to gram per meter control of product, to full-calculated gauge control, typically for co-extrusion processes.
With the loss in weight hopper mounted on the throat of the extruder, the system constantly updates the current kg/h.
At the simplest level of control this information can then be used to interface to the extruder drive speed control, and once switched to automatic control the system will automatically adjust the speed of the extruder to ensure the target kg/h is always met.
Further levels of control include a digital encoder to monitor linespeed. With the addition of the digital encoder the system utilizes the linespeed meters per minute confirming exactly how quickly the line is running at. The metres per minute combined with the kg/h provides the calculated gram per metre or micron, and from there the LineMaster systems can automatically regulate the control of the line either by the speed of the extruder drive, haul off drive, or both.
