Extrusion International 2-2018

53 Extrusion International 2/2018 KraussMaffei Berstorff GmbH www.kraussmaffeiberstorff.com Hall West, Booth W403 Using the unique liquid color compounding process, master- batches of any color - whether green, blue, purple, pink or orange - can be produced in a single cycle without the inter- mediate mono-concentrate production step for maximum cost-effectiveness. And that is exactly the solution KraussMaffei Berstorff will present in a live demonstration at their booth dur- ing this year’s NPE inOrlando: direct production of PE color mas- terbatches on a ZE 28 BluePower extruder. Visitors will be able to witness the unparalleled efficiency of the latest twin-screw extruder model in terms of melt homogeneity, color precision and flexibility. Liquid Color Compounding Technology producedmasterbatch- es with unique color precision: The ZE 28 BluePower used in the NPE live demonstration with a length of 46 D is equipped with a liquid and solids metering system, so that color masterbatches can be produced of any type of startingmaterial. Color masterbatches are usually based on mono-concentrates, which are produced on single-screw extruders in a separate process step, intermediately stored and then fed into the twin-screwextruder in a second step. With the liquid color compounding technology, the intermediate mono- concentrate production step is no longer required. The resulting color masterbatches stand out for unparalleled cost-effective- ness andunique color precision. As our twin-screwextruders are self-cleaning, changes from dark to bright colors can be made without any problems. KraussMaffei Berstorff offers customers adequate recipes stored in the proprietary Process Control AD- VANCED system, which are automatically set for the complete line at the simple push of a button on the control panel. The compounding line exhibited at the fair is equippedwith an Econ underwater pelletizer. ZE 28 BluePower laboratory extruder with wide range of pro- cess tasks: The BluePower series are a generation of trend-setting com- pounding extruders that perfectly meet the ever increasing requirements of compound processors in terms of high energy efficiency, cost-effectiveness, safety at work, simple use and low maintenance efforts. Thanks to the wide range of process tasks and processingmaterials, is the ZE 28 BluePower twin-screw ex- truder the ideally suited for research and development applica- tions as well as for small-batch production. All extruders in the ZE BluePower series feature an OD/ID diameter ratio of 1.65, a specific torque from 13,6 up to 16 Nm/cm3 and high drive power and are rated for speeds from 900 rpm up to 1,200 rpm. The highlights of the ZE BluePower extruders are higher torque oval liners by simultaneously in- creased free volume, improved side feeders and degassing units aswell as the optional energymanagement tool. The 4Dand 6D barrel sections that can be combined with the extensive range of modular screw elements to bespoke machinery configura- tions for any application are simply unique in the market. Cost-effective Color Masterbatch Production in a Single Cycle ZE 28 BluePower laboratory extruder produces color masterbatches economical and in high quality 48$/,7< 352'8&76 6,1&( (5*( ( OHNWURZlUPHWHFKQLN )UDQ] 0 HVVHU *PE+ 6 FKQDLWWDFK ‡ +HUVEUXFNHU 6WUD‰H 7HO ‡ )D[ ZZZ HU JH HOHNWURZDHUPHWHFKQLN GH (/(.752:b50(7(&+1,. )5$1= 0(66(5 (5*( 0()/(; &HUDPLF +HDWHUV PRUH KHDWLQJ VXUIDFH EHWWHU KHDW FRQGXFWDQFH 7RJHWKHU ZLWK WKH HQHUJ\ RSWLPL]HG (5*( :'* +HDW ,QVXODWLRQ -DFNHW WKH XOWLPDWH HQHUJ\ VDYLQJ VROXWLRQ 1(: ‡ %(77(5 ‡ )25 :,11(56 21/< -LD;LQJ (5*( (OHFWULF +HDW 7HFKQRORJ\ &R /WG <DQ %HL 5RDG +DL\DQ =KHMLDQJ &KLQD 3RVWFRGH 3KRQH ‡ ZZZ HUJHFKLQD FRP Booth Stand 5.1R03
