Extrusion Control System Enables Maximized Wire and Cable Production
An innovative extrusion control system for wire and cable that provides accurate control of grams-per-meter yield, improves product integrity, and reduces operating costs was announced today by Maguire Europe.
The Maguire and Syncro Group extrusion control system can be deployed in extrusion or co-extrusion operations and in new or retrofit installations. Using data from a digital post-extrusion encoder and tachometer, the system adjusts extruder screw RPM and capstan speed to ensure tight coating tolerances and end-product consistency. In co-extrusion, ratio control provides accurate dimensions for multiple sheathing layers or identifying stripes.
Three Basic Components
The first, the Maguire WXB Weigh Extrusion Blender, incorporates a gain-in-weight (GIW) weigh bin and a loss-in-weight (LIW) mix chamber. The Maguire 4088 controller controls the loading, blending, and metering of raw material to the extrusion process. Thirdly, the Syncro controller uses the consumption data from the 4088 controller and the downstream encoders to adjust line speed and haul-off.
Modes of extrusion control available with the Maguire and Syncro system include grams per meter of extruded product and kilograms per hour (imperial units also apply).
Maguire Europe MD Paul Edmondson said: “Given the high speeds in wire and cable extrusion, any coating errors can quickly escalate into severe rejection rates, extensive downtime, and costly waste … The Maguire and Syncro extrusion control system enables the manufacturer to maximize throughput while maintaining tight tolerances, drawing on Maguire’s expertise in control of material handling with Syncro’s expertise in controlling extrusion lines.”
Maguire Europe will showcase the system at Wire 2020 on 07 to 11 December (Hall 10, Stand D37).
