Maguire Europe announced that it will highlight an innovative extrusion control system for wire and cable, which provides accurate control of grams-per-meter yield, improves product integrity, and reduces operating costs at Wire 2020 from March 30 to April 3 in Düsseldorf, Germany.

The Maguire + Syncro extrusion control system can be deployed in extrusion or coextrusion 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 coextrusion, ratio control provides accurate dimensions for multiple sheathing layers or identifying stripes.

There are three basic components in the Maguire + Syncro system:

1) the Maguire WXB Weigh Extrusion Blender, which incorporates a gain-in-weight (GIW) weigh bin and a loss-in-weight (LIW) mix chamber;

2) the Maguire 4088 controller, which controls the loading, blending, and metering of raw material to the extrusion process; and

3) the Syncro controller, which 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 + Syncro system include grams per meter (or ounces per foot) of extruded product and kilograms (or pounds) per hour.

“Given the high speeds in wire and cable extrusion, any coating errors can quickly escalate into severe rejection rates, extensive downtime, and costly waste of polymer compound and conductor or optical fiber,” said Paul Edmondson, managing director of Maguire Europe.

“The Maguire + 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.” 

The Maguire + Syncro system is the product of a partnership between Maguire and Italy-based Syncro srl that began in 2016 with Maguire taking an investment position with Syncro, which specializes in controls for all types of extrusion process.

The Syncro components in the extrusion control system for wire and cable include a master PLC touchscreen controller, digital encoder and tachometer, and a coextrusion interface (one for each layer) that provides polymer consumption data from each additional extruder via the Maguire WXB blender.

As color is a key factor in wire and cable for branding and coding, Maguire also supplies the MGF gravimetric feeder, which precisely measures the amount of additive that is fed directly into the extruder throat.
