Focus on eccentric screw pumps and pumps for shear-sensitive materials

Improved productivity and increased lifespan and tailored solutions also for the most demanding applications within the chemicals and plastics industries and in PUR applications – these are the convincing arguments with which Oerlikon Barmag is showcasing its precision metering pumps at this year’s ACHEMA between August 22 and 26, 2022 in Frankfurt. The focus is on the new pump for shear-sensitive conveying media and the new eccentric screw pump.

Eccentric screw pumps – robust all-rounders convey any medium
The requirements for pumps are considerable, as the demand for customized solutions for increasingly complex processes is rising. This is particularly true for Oerlikon Barmag’s new eccentric screw pump range. High wear-resistance, increased durability and robust operation – the new pump is tailor-made for conveying highly-filled, high-viscosity and abrasive media, such as filled adhesives, filled silicones and filled casting compounds, for example. The is the multi-stage seal system, which considerably increases the pump’s lifespan. The upstream shaft sealing ring protects the slide ring seal against excessively-fast wear caused by challenging media. In turn, the optimum alignment of the drive shaft – ball bearing-supported and centrally-guided through the shaft sealing ring – prevents any metal debris caused by friction and hence ensures considerably greater durability. Producers benefit from considerably greater productivity, as the pumps’ maintenance intervals and hence machine downtimes are significantly reduced.

New pump for shear-sensitive materials
For increasingly complex customer-specific process solutions, Oerlikon Barmag is now expanding its GA series, developed especially for the challenging conveying of high-viscosity media, to include the GAB51F for shear-sensitive conveying media. The newly-developed pump with its viscosity range of max. 300 Pas is tailored to conveying high-viscosity, shear-sensitive materials such as adhesives and silicones, for example. “The shear forces impacting the medium within the pump are reduced to a minimum as a result of a specially geometry”, explains Thorsten Wagener, Senior Sales Manager within the Pump Construction business unit. The material is conveyed through the pump in an as gentle and low-pulsation manner as possible and metered precisely at the outlet – ensuring it retains its characteristic properties.

High-speed metering pump with sealed product space
The high-speed metering pump has been especially developed for metering poorly-lubricating media. Here, the main benefit is the sealed product space, which extends the pump’s lifespan considerably. The space that comes into contact with the media is limited to the area around the gears. “As a result, the high-speed pump is particularly suited for applications in the chemicals industry, which frequently involve aggressive acids”, comments Thorsten Wagener.

GM series for low-viscosity media
The pumps in the GM and GA series provide precision metering with low-pulsation feeding of the conveying medium. The multi-stage GM pump conveys low-viscosity media (i.e. 250 bar, 100 mPas) even under high pressure and in the most challenging conditions. The square design from the proven GM series is the standard pump for many metering tasks. The development of the multi-stage pump expands the applications range for the GM series considerably. The round 2-stage GM pump has been developed especially for use in high-pressure technology. It masters the particular challenge of conveying small throughputs with low viscosities. The pump is perfect for 0.05 through 20 cm³/rev feed sizes and is excellently suited for use in high-pressure machines for PUR molded parts, foam slab stock, refrigeration unit insulations and sandwich panels, for example.

GA series pumps for high-viscosity media
The Oerlikon Barmag GA range has been especially developed for the challenging conveying of media with higher viscosities. The GA series pumps are available for conveying volumes of between 1.25 and -30 cm³/rev (0.6-144 l/h). They have been designed for pressures of up to 200 bar, for viscosities of up to 1.500 Pas as well as for temperatures of up to max. 225 °C. With this range of pumps, Oerlikon Barmag offers its customers tailor-made solutions for many technical processes in which high-precision and even metering is of paramount importance.

The drum pump – conveying and metering using a single unit
With the drum pump, the Oerlikon Barmag pump specialists have created a pump designed specifically for conveying and metering high-viscosity materials such as adhesives, silicones and other high-viscosity materials from drums and other large containers and for pressures of up to 250 bar. Its special features not only include the fact that it removes high-viscosity materials from the drum, but that it also meters the medium directly without any additional interim stops.

EURATEX has just released its Spring report, offering a detailed insight into trade figures for the European textile and apparel industry in 2021. The numbers are encouraging: comparing with the dramatic corona-year 2020, EU exports of textile and clothing articles increased by +10.6%, while imports dipped by -7.5%. As a result, the EU trade deficit improved, even it remains significant (- €48 billion).

Furthermore, import prices went slightly down in clothing and dropped in textiles, following a strong decrease of Chinese import prices of face masks and protective medical supplies.

The boost in exports was mainly due to strong performance on the Swiss, Chinese and US markets. On the other side, EU sales of textile & clothing to the United Kingdom fell sharply (-23%), due to Brexit new requirements, customs’ delays and shortage of truck drivers.  Imports from the EU top supplier, China, plunged by -28%, corresponding to €13 billion. Similarly, textile and clothing imports from the United Kingdom recorded a sharp decrease over the period (-48%, equal to €-3 billion).

Director General Dirk Vantyghem commented: “the 2021 export figures, presented in this Spring report, confirm that EURATEX members have gained momentum; even if energy prices are causing some serious short-term disruptions, our long-term ambition remains to be a world leader on sustainable textiles.”

The international trade dimension is indeed critical for the competitiveness of the European textile ecosystem, and needs to be fully embedded in the EU’s Strategy for Sustainable and Circular Textiles. The Commission insists that “all textile products placed on the EU market, are durable, free of hazardous substances, produced respecting social standards…” This is an essential condition to create a level playing field between all textile and apparel companies, regardless of their production base. With €100 billion of imports, and over 20 billion of “foreign” textile items put on the Single Market, this requires a dramatic upscaling of market surveillance, without however disrupting fluid supply chains.

Looking at the impact of war in Ukraine, EURATEX has strongly condemned the Russian aggression, and offered support to the Ukrainian textile industry. Ukraine offers valuable sourcing opportunities for European textile and apparel brands, as part of a broader nearshoring trend, which seems to emerge from the trade figures.

• Hypetex® to Showcase Coloured Carbon and Flax Fibre Solutions
• Hypetex, London, April 20 2022, Booth R52, Hall 6

Hypetex, the market leaders in colouring carbon and natural fibre materials, will demonstrate both the processing and sustainability benefits of its patented colourisation technology when it exhibits for the first time at JEC World 2022.

Exhibiting as part of the Composites UK stand (Booth R52), Hypetex will display its portfolio of uniquely coloured carbon fibre materials including 3K woven styles, ultra-lightweight spread tow fabrics, UD, and 3D materials. Hypetex will also present details of its latest eco-friendly coloured flax materials  which combine sustainably grown natural flax with sustainable colouring technologies. Hypetex patented colouring technology, available in an extensive palette of standard and bespoke colours and shades, can be applied to traditional woven fabric constructions, non-woven UDs, spread tow and bespoke fabric designs. The technology replaces a traditional coloured painted finish, providing an exceptional depth of colour to any composite part, improving thermal conductivity and reducing heat absorption ,whilst reducing the overall weight and processing time with no compromise to the mechanical performance of the composite structure.

By removing the need for painting, and the associated preparation steps, Hypetex technology provides manufacturers with a repeatable straight out of the mould coloured finish, that is not only easy to integrate into all composite processes, but also takes additional materials, consumables, and process time out of the component cost. As part of its continued commitment to leading the drive for more sustainable composite solutions, and its focus on improvements based on the ESG framework. Hypetex will also display its new range of coloured flax fibre textiles. The advanced colouring technology used protects the natural flax fibres throughout the high temperature processes required for composite production, avoiding burning or any discolouration issues common to natural fibres. In addition, Hypetex colouring solution is an ecofriendly sustainable alternative to traditional dyeing processes which are a significant cause of global water pollution.

The Hypetex team will be on hand throughout the show to provide additional details on Hypetex materials and their integration into the manufacturing process. Visitors to the Hypetex stand will be able see Hypetex carbon and flax products in raw fabric, and how its unique colour palette translates into the most distinctive finished moulded components. Hypetex partners SHD Composites, Textreme, Sigmatex and Angeloni will also have materials and components on display at JEC World 2022, including sporting equipment such as racquets, sticks, and skateboards, which highlight the massive range of processing options and potential applications for this novel technology. One such application, the adidas Kromaskin field hockey stick, with a unique Hypetex coloured Textreme spread tow carbon finish, will also be part of the JEC Innovation Planets feature.

On March 10th, JEC Group and Composites Expert have signed a partnership agreement to promote E-learning Composites Academy, the first 4.0 training platform dedicated to manufacturing processes of composite materials.

• Hexcel HexPly® XF Selected for High-Quality, Paint-Ready Parts for Sunseeker 90 Ocean Luxury Yacht
• Hexcel’s innovative surface technology yields parts with paint-ready surfaces for builder of luxury yachts

Yacht builder Sunseeker has chosen Hexcel’s HexPly® XF surface technology to produce prepreg parts with high-quality, paint-ready surfaces quickly and efficiently for its 90 Ocean luxury yacht, one of its newest models.

The lightweight composite hardtop for the Sunseeker 90 Ocean yacht is manufactured from a combination of HexPly® XF and Hexcel's HexPly® SuperFIT® semi-preg. The hardtop is lighter in weight than versions made using resin-infusion processes, and it de-molds with a pinhole-free surface that needs minimal preparation to be ready for paint. Sunseeker has recorded an overall reduction in process time of around 30%, saving three days of manufacturing time per hardtop.

The hardtop provides shade and protection for the yacht’s uppermost deck space. Its reduced weight helps to ensure the stability of the vessel, and the paint-ready finish with HexPly XF provides Sunseeker with more options for customizing its color to the individual needs of its clients.
 
HexPly XF is a lightweight, non-woven semi-preg that eliminates the need to use a traditional in-mold gel coat. The innovative surface technology significantly reduces the costly and time-consuming refinishing work typically required to impart a paint-ready finish to prepreg or semi-preg parts, and yields lightweight, consistent components in short cycle times.

Working with Sunseeker, Hexcel developed a material format, a laminate ply sequence, and a production process that satisfied the structural requirements for the hardtop and enabled the yacht builder’s production team to lay up and cure the part in a single shot – slashing cycle times.

Hexcel supplies Sunseeker with a HexPly XF product that comprises both the surface layer and the first structural reinforcement ply, eliminating the need for a cosmetic barrier coat. Neither the HexPly XF surface layer nor the following layers of HexPly SuperFIT require time-consuming debulking steps – significantly reducing lay-up time – and both are based on Hexcel's rapid-curing M79 epoxy resin system. Adhesive resin films are not needed to bond the hardtop’s foam core, as the resin content of the SuperFIT plies has been adjusted to further reduce overall process time.

Once de-molded, the cured hardtops are inspected before they are passed to Sunseeker’s finishing and painting technicians for final preparation and painting. The HexPly XF resin surface allows the yacht builder’s quality technicians to inspect the laminate below quickly and easily, ensuring the quality and consistency of the structural reinforcement plies.

“Composite materials that improve our production processes, as well as great technical support, are what makes working with Hexcel such a success story," said Stuart Vaughan-Jones, Composite Development Manager, Sunseeker. "With the switch from gel coat and resin infusion to HexPly XF and SuperFIT in the new hardtops, we are now building lighter, more consistent parts, more quickly than before, with a higher quality surface finish. XF really has ticked all the boxes.”  

Garth Thomas, Account Manager – Marine, Hexcel, said: "With the HexPly XF surface technology now well established, XF will soon be used in other large moldings where minimizing weight is critical, as well as additional hardtops across the Sunseeker model range."

Avgol, an Indorama Ventures company and manufacturer of high-performance nonwoven fabric solutions, will be showcasing its latest work in biotransformation technology for polyolefin fibers and nonwoven fabrics at this year’s Hygienix™ event.

The Avgol presentation, part of the Product & Process Innovation in AHPs series, will take place at 2pm on Tuesday, November 16.

From their base at the tabletop event, Nick and the Avgol team will be discussing the global challenge of eliminating incineration, chemical treatment, landfill, dumping and, in particular, fugitive material pollution from non-woven products.

“Following our recent success at Index 20, we will be sharing insight to our research and development strategy with Hygienix attendees, addressing the degradation performance of our products and the path forward for the industry in terms of the use of new bio-colorants, biosurfactants and new technologies. Of course, we will also be demonstrating our latest Forward Innovative Thinking (FITTM) range of hygiene materials too, including natureFITTM”, says Nick Carter.

natureFIT™ is the newest innovation in the Avgol™ technology platform, designed to imbue nonwoven fabrics with additional qualities and benefits that anticipate the shifting demands of the consumer-led retail space. The suite of fabric solutions is focused on replacing elements of spun melt fabric design, where possible, with natural alternatives. The advanced technology affords product designers a significant reduction in polymer consumption to reduce environmental impact while simultaneously enhancing softness and conformability.

Hygienix™ runs from 15 – 18 November 2021 at the Westin Kierland Resort in Scottsdale, Arizona, USA.

• DiloGroup looks forward to participating in the Techtextil India show 2021.

DiloGroup offers tailor-made production systems from one supplier and will inform at this forum in the German pavillon about its portfolio and the latest equipment developments from fibre opening to the finished felt.

A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further by using the new needle pattern 8000X which is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

The “3D-Lofter” which was first presented during ITMA 2019 in Barcelona offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts are two examples for this technology which explores new application areas for needlefelts.

The 3D-Lofter technology may also be used “inverted” for filling up bad spots in web mats and thus achieves a better homogeneity of e. g. spunlace, thermobond or airlay products. The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

With more than 370 installations delivered to the nonwovens industry worldwide, DiloGroup has the necessary know-how and the complete equipment portfolio to engineer the perfect production line for any product specification. The efficiency of Dilo production lines is the result of long-term research work and experience. Apart from machines for needling technology we offer in cooperation with partner companies also production lines including thermobonding and hydroentangling components.

• Composites in the construction industry - The lightweight construction material of the future

Building with fibre-reinforced materials opens up completely new possibilities. In terms of engineering, design, and organisation. This is due, on the one hand, to the excellent properties of fibre-reinforced materials (FRM) and, on the other hand, to the fact that the material – unlike wood or brick, for example – is not machined or processed for its use, but custom-produced.

Excellent properties – in terms of engineering, design, and organisation
Fibre-composite materials offer a whole range of technical properties for innovative and sustainable building:
•    High mechanical rigidity
•    Low weight
•    High corrosion resistance
•    Low material fatigue
•    Low heat transfer coefficient of the plastic matrix
•    Resistance to frost and de-icing salt
•    Good draping capability

In addition, fibre composites offer numerous design options for novel and exceptional new building and maintenance projects:
•    Unique variety of shapes
•    Different structures of the textiles
•    Large spectrum of colours and colour combinations
•    Translucency of the plastic matrix
Thanks to these properties, composites can be used to produce coloured, phosphorescent, thermochromic or – through the use of LEDs or light-conducting fibres permanently integrated into the matrix – luminescent components.

In addition, there are organisational benefits for planning, construction and maintenance work with fibre-reinforced materials:
•    Easier handling and assembly of the far lighter and more flexible components – compared with steel, concrete or wood
•    Faster installation
•    Shorter construction site times in road and bridge maintenance
•    Shorter delivery times
•    Ability to integrate electronic monitoring systems
