Extrusion International 5-2025-USA

35 Extrusion International 5/2025 lets, lm akes or agglomerate with no pre-treatment are introduced into a ZSK twin screw extruder where they are melted, homogenized and devolatilized. The melt is then fed through a lter, removing any contaminants. In the subsequent compounding process additives are intro- duced into the melt prior to pelletizing the compound. To fully exploit the ZSK FilCo’s high performance, raw materials must be supplied at a constant rate with no intake limits. While this can be accomplished either by pelletizing the waste plastic or regrind, or by using a compacting process, these are very energy-intensive processes and increase both capital and operating costs. In contrast, the ZS-B MEGAfeed side feeder, on display in Pavilion FG/CE07, reliably feeds recycled materials with a bulk density as low as 20 kg/m³ into the ZSK FilCo and other ZSK extruders. This allows for recycling and compounding of lightweight, high-volume bers and akes at high throughputs. Seamless connection of bulk material handling and feeding technology Coperion is an expert in numerous feeding technologies that stand out with their high-accuracy and easy handling. Representative of this ex- pertise, in Pavilion FG/CE07 Coperion will display a Coperion K-Tron K3- V200 vibratory feeder that excels in providing high-accuracy grav- imetric feeding particularly for challenging ma- terials, for example where smaller recyclates or akes are being fed into the extrusion process. For light and uffy, hard-to-feed materials such as polypropylene or PET plastic lm, Coperion will showcase the MechaTron FB ( at bottom) feeder, a gravimetric feeder ideal for high-capacity recycling op- erations. Also on display is the Coperion K-Tron S60 single screw feeder, another feed- er the provides very high reli- ability. Coperion developed its ZRD rota- ry valve especially for plastics recycling processes. Together with the new drive technology, the new design of the gap between the rotor and housing ensures reliable discharge of akes. 10 Pike Street West Warwick, RI 02893 Email: sales@guill.com To find out more, visit www.guill.com Revolutionary New Cam Lock Design Available on the Bullet, Guill’s Cam Lock is now offered on other heads where applicable. The Cam Lock feature allows quick and easy assembly and disassembly of the crosshead and eliminates socket head cap screws. By removing and replacing the internals, a different profile can be extruded in minutes rather than hours. This translates into BIG SAVINGS for your production.

In combination with the ZS-B MEGAfeed side feeder, the ZSK FilCo’s high performance is fully exploited (All photos: Coperion, Stuttgart Germany) Coperion K-Tron K3 vibratory feeders are equipped with a unique drive system and are suitable for high-accuracy feeding of recycling materials
