KraussMaffei at NPE: “Make Plastic Green”

“Make plastic green – with high quality and efficiency” – this is KraussMaffei’s motto at the NPE show in Orlando, Florida (May 6 to 10, West Hall A, booth W600). Front and centre of the trade show appearance are innovative technologies and solutions of injection moulding, extrusion, reaction process machinery, automation and additive manufacturing focusing on circular economy and reducing the CO2 footprint.

“Sustainability is an added value – for us and for our customers. In line with our motto ‘We make plastic green’, we therefore aim to be a leading global supplier of sustainable solutions for the plastics processing industry”, explains Nolan Strall, President KraussMaffei Corporation. In order to achieve these goals, the circular economy is a supporting pillar of KraussMaffei’s corporate strategy.

Circular economy live @NPE

Trade show visitors at NPE can experience the entire material cycle, from a short-lived medical blood vial to a long-live bottle opener, at the KraussMaffei booth. Starting with injection moulding on a PX 251-1400, moving on to the upcycling process and to the twin-screw extruder ZE 28 BluePower and then to the all-electric injection moulding machine PX 81-180, KraussMaffei demonstrates everything from valuable utilisation of raw materials from disposable articles to production of premium quality components with long service life.

The all-electric PX 251-1400 produces 32 medical blood vials per shot from PP 9074 MED material supplied by ExxonMobil. After shredding, these vials serve as a base material for the up-cycling process carried out on the ZE 28 BluePower twin-screw extruder. Here, various additives such as bonding agents and liquid pigments are added, mixed and homogenised. The resulting re-compound is transferred to the downstream injection moulding machine – more precisely to an all-electric PX 81-180.

As recyclates can cause significant process fluctuations due to different viscosities, the PX 81-180 is equipped with APCplus. This machine function reliably compensates for these fluctuations. This allows components to be produced with consistently high quality with scrap reduced to a minimum – another important contribution to greater sustainability.

Saving CO2 and costs with DCIM

Another highlight from the area of sustainable solutions at the KraussMaffei booth is the DCIM process (Direct Compounding Injection Moulding) with which up to 50% of material costs can be saved, also giving the processor considerably more freedom and control in the development of formulas. For DCIM, a single-screw extruder is installed in a space-saving piggyback position directly over the injection unit of a standard hydraulic machine.

The compounded melt is conveyed into the plasticising unit in a single heating process, which reduces the degradation of the polymer. In addition, the one-step process conserves energy and reduces the CO2 footprint. At the NPE show, a GX 1100-4300 DCIM will produce rugged reusable crates made of three different recycled materials.

The intuitive machine function smartOperation allows the startup and control of the injection moulding machine as easy as using a coffee machine. This not only enables defect-free machine operation but also increases process stability and thus boosts efficiency in production. In particular, machine operators without in-depth prior knowledge of injection moulding technology benefit from the advantages of smartOperation.

New MuCell screw with 30% higher plasticising performance

MuCell can do everything that’s currently in demand—generate savings on material, energy and investment costs—and thus noticeably reduce the CO2 footprint of products. At the NPE show KraussMaffei is highlighting its new universal screw for MuCell applications with 30% higher plasticising performance.

The new HPS-Physical Foaming screw has a longer three-zone area, which can be universally used for all plastics (with and without fiber reinforcement) and has a plasticising capacity that has increased by up to 30%. This allows for the selection of lesser screw diameters than before, which significantly reduces investment and operating costs for the plasticising unit, or for the generation of a greater output using a screw of the same size as before.

PX 121-180 SilcoSet: Live production of matrix lenses made of LSR

Silicones, and particularly the new generations of LSR (liquid silicone rubber), continue to conquer new application areas thanks to their excellent physical property patterns, offering great opportunities for growth. At the same time, however, they burden the processor with challenges when it comes to precision and process consistency in the injection moulding process. At the NPE show, a PX 121-180 SilcoSet produces matrix lenses for the headlight industry.

The machine function APCplus supports sustainable production here by continuously analysing the injection moulding process and quickly and accurately compensating for material- and environment-related fluctuations in melt viscosity. This ensures a consistently high component quality and thus minimum scrap.

The two-cavity LSR matrix mould comes from mould specialist ACH Solution providing the best temperature balancing even with longer scheduled downtimes. The ACH Servoshot 2G stands for precise needle valve regulation. The linear robot LRX 150 from KraussMaffei with EOT from ACH Solution allows an inline production with inspections, weight checks and separation.

Large-scale production also in aviation – Partnership with NIAR

Another highlight at the KraussMaffei booth is the manufacturing demonstrator Frankenstein from the National Institute for Aviation Research (NIAR) at Wichita State University. It showcases different examples of how to introduce automotive-matured ultra-high-rate manufacturing technologies to aerospace – a joint research program NIAR and KraussMaffei are driving forward together.

In addition, NIAR will show the inlet duct of a 10-meter-long unmanned system manufactured using a proprietary meltable tooling concept developed by Fiber Dynamics, Wichita, Kansas/USA. A further highlight is an aircraft window plug that is currently undergoing certification efforts for aircraft passenger-to-cargo conversion activities at NIAR.

These composite parts are manufactured using the FiberForm technology developed by KraussMaffei. The process combines the thermoforming of organic sheets and injection moulding in a single process. The result is particularly lightweight fibre-reinforced plastic components with a high level of strength. Until now, they have mainly been used in the automotive industry. The cooperation between NIAR and KraussMaffei has now paved the way for FiberForm to be used in aerospace applications as well.

Future mobility – Clemson University shows driverless concept vehicle

Another partner at the KraussMaffei booth will be Clemson University. They will showcase its advanced materials and manufacturing expertise via multiple projects in mobility industries. Specially highlighted is an ultra-efficient driverless concept vehicle designed for the year 2035.

Clemson students and faculty worked with ExxonMobil Chemical and Honda North America to engineer, build, and validate the prototype with a special focus on sustainability, resulting in a design with 18% plastics and composites by weight – nearly double the 10% market average. Built with reclaimed, lightweight, and recyclable advanced materials, the project exemplifies the highly translational and rapid R&D engineering possible at Clemson.

Ultra lightweight: Premiere for first HP-RTM bike in the US

TIME Bicycles, in partnership with KraussMaffei, Fraunhofer USA and Clemson University is raising the bar of composite bicycle technology through a special development project to introduce HP-RTM (High Pressure Resin Transfer Moulding) to the cycling industry.

At the NPE show, they are showcasing the first, USA-produced HP-RTM bicycle to the world. Visitors to the show can register for a giveaway from the first production. The retail value of the complete bicycle is 8,000 USD. TIME Bicycles was founded in France in 1987 and is the leading European manufacturer of carbon fibre bicycles, specialising in Resin Transfer Moulding (RTM).

More transparency and efficiency with socialProduction

All injection moulding machines at the booth are connected to socialProduction via the KraussMaffei smartCube. The socialProduction product family enables intuitive monitoring of the injection molding machines, the production process and the condition of the machine components.

productionMonitor, for example, guarantees a quick overview of the machinery and helps to efficiently monitor each connected machine with intelligent production key figures. With processSupport, the process is monitored autonomously using artificial intelligence. The early detection of deviations and proactive communication to the operator increase efficiency.

The liveCare condition monitoring solution offers continuous online monitoring of the condition of the machine components. This enables the implementation of condition-based maintenance strategies. EnergyControl ensures that energy consumption is optimised. The module provides a detailed insight into the total energy consumption of the injection moulding machine and the individual machine components, including energy-related CO2 emissions.

US market debut of additive manufacturing solutions

KraussMaffei has achieved a significant milestone by successfully introducing its additive manufacturing solutions and services in the EMEA market. Starting in the second half of the year, these industrial AM systems will also be available for the US market. A key component of this offering is the innovative LSAM (Large Scale Additive Manufacturing) system, powerPrint alongside the precisionPrint stereolithography system.

At the NPE, KraussMaffei will showcase current case studies and solutions that illustrate the impressive capabilities of powerPrint. The powerPrint excels in processing large parts while leveraging the advantages of 3D printing.
