Using the unique liquid color compounding process, masterbatches of any color – whether green, blue, purple, pink or orange – can be produced in a single cycle without the intermediate 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 W403 in hall West during this year’s NPE, May 2018, Orlando: direct production of PE color masterbatches 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 produced masterbatches 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 starting material. 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-screw extruder in a second step. With the liquid color compounding technology, the intermediate monoconcentrate production step is no longer required. The resulting color masterbatches stand out for unparalleled cost-effectiveness and unique color precision. As our twin-screw extruders 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 ADVANCED 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 equipped with an Econ underwater pelletizer.
ZE 28 BluePower laboratory extruder with wide range of process tasks
The BluePower series are a generation of trend-setting compounding 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 processing materials, is the ZE 28 BluePower twin-screw extruder the ideally suited for research and development applications 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 increased free volume, improved side feeders and degassing units as well as the optional energy management tool. The 4D and 6D barrel sections that can be combined with the extensive range of modular screw elements to bespoke machinery configurations for any application are simply unique in the market.
