At K 2013, the "extrusioneers" presented themselves with the motto "Rethinking Technology." After three years of lateral thinking and of scrutinizing solutions, appetite for technical progress will now be whetted with a professionally staged presence.

One of the highlights presented at the Reifenhäuser booth at the last K show in Düsseldorf, Germany, was the debut of a new EVO line generation (Fig. 1). EVO lines are intended to provide easy operation, maintenance and cleaning. Functional operating elements, together with clear and tidy surfaces, form the basis for high productivity.

The new WXB Weigh Extrusion Blender from Maguire Products, Inc., Aston/Pennsylvania (USA), incorporates a gain-in-weight (GIW) weigh bin and a loss-in-weight (LIW) mix chamber in one machine with a Maguire 4088 controller. According to the manufacturer, the tight tolerance achieved by the blender (within +/- 0.1%) is a key to conserving raw material.

Call for papers for a symposium for lateral thinkers  

One way to increase recyclability is to use mono-material film. But such film must not be inferior in any way to its multi-layer predecessors. Brückner Maschinenbau GmbH & Co. KG, Siegsdorf, Germany, has therefore developed a new inline coater (ILC) for all BOPP and BOPE lines that is installed in the line upstream of transversal stretching. The manufacturer claims it can produce extremely thin functional layers in the nano range. The extreme thinness of the layers means that they do not disrupt sorting and recycling, but do allow, for example, improved adhesion during metallizing and excellent barrier properties in conjunction with very thin aluminum oxide coatings.

Macchi presented at K the new Pod-Flex series for the production of seven-layer blown films with a net width of 2700 mm. The extrusion line can extrude laminate, barrier and biomaterials, since the new TES72 extrusion die, which is completely PVD-coated, can process both polyolefin and barrier-film formulations on the same line.

Higher Speed for Material Exchange 

In order to avoid bubble ruptures during the production of blown film, the velocity of the cooling air is often reduced. The use of air guiding systems (AGS) can prevent such bubble instability. A novel AGS was developed at IKV in Aachen, Germany, using iris diaphragms in order to increase the cooling efficiency of blown film extrusion and thus improve the productivity of an existing plant

On the Spot at Windmöller & Hölscher

Reifenhäuser Blown Film has developed a technology intended to make manufacturers of blown film independent of strongly fluctuating recyclate qualities and ensure a stable production process – even when processing low-quality input material.

Even fluff (film scrap) and all kinds of production waste and PCR material can be directly processed.

Reifenhäuser Focuses on Automation in Film Production

The Reifenhäuser Group will showcase its latest solutions for sustainable and efficient blown and flat film production at Plastindia 2023 in New Delhi.

The Reifenhäuser Group will showcase its latest solutions for sustainable and efficient blown and flat film production at Plastindia 2023 in New Delhi. Highlights include the processing of low-quality recyclate into high-quality blown film, the PAM automation option for coextrusion adapters and flat dies, and the production of high-barrier tube film in just one process step.

At Plastindia 2023 (from February 1 to 5), Reifenhäuser Blown Film presents the technical solution to one of the biggest challenges in processing recyclate – the often low and fluctuating quality of the input material. Producers have so far found it difficult to set up a stable production process for higher-quality end products made from recyclate. With EVO Fusion, blown film producers can now process previously unusable, low-cost recyclate into high-performance blown films for end-use applications such as trash bags or mailing bags.

The key lies in the twin-screw technology of the EVO Fusion extruder, which improves melt homogeneity and ensures a stable process. Processors can also degas the system very easily and effectively, removing unwanted components in the recyclate. The EVO Fusion process also enables direct extrusion, which eliminates the need for energy- and cost-intensive regranulation of the material. This means that fluff (film shreds), all types of production waste, and PCR material can also be processed directly. To process better quality regranulate, Reifenhäuser recommends the EVO Ultra single-screw extruder. This machine processes recycled material as reliably as other raw materials, thanks to optimized barrier as well as shear and mixing parts.

Eugen Friedel, Director Sales at Reifenhäuser Blown Film, explains: “Our technologies for recyclate processing offer the ideal prerequisite for participating on the growing market for products with high recyclate content. Moreover, India already has legal requirements governing the use of recyclate which our customers can easily meet thanks to EVO Fusion.“

Automated Adjustment of Coextrusion Adapter and Die

Precise, autonomous, mechatronic – with the PAM option, Reifenhäuser Cast Sheet Coating will demonstrate in New Delhi, India, how flat film producers can fully automate the adjustment of coextrusion adapter and die. In the past, this was mostly done manually. This enables faster start-up of production, higher output, and improved overall equipment efficiency (OEE). Scrap and material usage are significantly reduced. Once recipes have been set, they can be stored and recalled at any time. They can therefore be reproduced exactly – even by inexperienced line operators.

At the heart of the PAM system are motorized screwdrivers which profile the film layers on the coextrusion adapter automatically with high precision and set and control the die flex lip. Depending on the die design, it is also possible to adjust the dust bar, width, and lip opening automatically by adjusting the lower die lip. The PAM option is exclusively available for the Reifenhäuser Coextrusion Adapter Pro, the only coextrusion system on the market that allows profiling of individual layers while the line is running. For flat dies, PAM is available as an optional feature for Reifenhäuser dies and also as a retrofit option for third-party systems.

Benjamin Pott, Sales Manager at Reifenhäuser Cast Sheet Coating, explains, “The PAM option is a unique solution on the market to enable producers to achieve enormous increases in line efficiency. It can be selected independently for coextrusion adapters and dies – but in combination, the automated components develop their full potential.“ The Reifenhäuser Group, one of the few machine builders on the market, manufactures all hot parts in-house – extruder, coextrusion system, and die. With this hot part competence, Reifenhäuser can design all process-related interfaces to match each other perfectly – PAM takes the whole thing to a new level.
