Theysohn Extrusionstechnik: Impressive Order From China

Thursday, April 10th, 2003

Theysohn Extrusionstechnik could strengthen their market position through an additional order of 72 complete window-profile production lines with a total of 132 tools and 8 mixing stations.
Over the last couple of years, including this order, more than 300 high-output window-profile lines with 550 single and double strand tools and 20 material mixing stations were delivered to their customers.
Due to a high increase of orders in 2002 the plant in Korneuburg was increased in size by 1000 m² production and 380 m² office space. With this additions Theysohn Extrusionstechnik have now 2500 m² production, 1000 m² for R&D, 100 m² mixing and 1000 m² office space at their disposal. The process of strengthening the organisation in the areas of Sales, R&D, Service and After Sales, that was started in 2002 will consequently be continued in 2003 to guarantee the high standard of service to the customers even with increased turnover.

The product-portfolio is still lead by the window-profiles ahead of the 3 layer-foam core pipe and the standard pipes. Fibre / Polymer compounds (rice shells, wood flour) will gain importance in 2003 because of Theysohns experience in the Asian Market.
The year 2003 started to be a promising one too. With already 40 Mio. Euro orders in process Theysohn’s annual turnover will increase by at least 5 %. The number of produced conical and parallel twin-screw extruders will exceed 145. In 2003 Theysohn Extrusionstechnik will continue to increase the turnover and the number of produced extruders and will contrary to the overall market situation develop further.

Battenfeld: Optimal wear resistance for screws

Thursday, April 10th, 2003

With the development of the new BEXalit coating for twin screws, Battenfeld Extrusionstechnik GmbH, Bad Oeynhausen, Germany has optimized resistance to wear and product safety. Practical tests have furnished convincing proof: BEXalit-protected screws show up to 100 % higher resistance to wear compared with conventional nitrided screws.
As a system supplier of complete solutions for the extrusion industry, the German machine manufacturer is familiar with the importance of high wear resistance in all components. Due to the growing amount of abrasive and corrosive ingredients in plastic materials processed as well as the continuous increase in twin-screw extruder performance, there is also a need for higher standards of wear resistance. For many years, Battenfeld has been working on solutions to meet this challenge. Now BEXalit coating, together with the optimized screw geometry of the 28 D generation, marks another technological milestone for twin-screw extruders.
Because of their complex screw geometry, repeatable protective coating of twin screws is only possible with a highly sophisticated automatic process. Therefore Battenfeld uses a plasma powder deposition (PTA) process. The low degree of blending and the perfect metallic bond formed between the protective coating and the basic material prevent tension cracks forming in the functional layer by means of controlled pre-heating and cooling during the coating process. The smooth running properties between the BEXalit screw and the barrel wall are further improved by subsequent plasma nitration. Therefore, BEXalit-coated twin screws combined with low-cost nitrided barrels are now incorporated into Battenfeld extrusion systems as standard accessories. The enormous cost advantages speak for themselves.

Du Pont: Teflon® fluoropolymers with high transparency and antistatic properties

Tuesday, April 8th, 2003

DuPont Fluoropolymers will be exhibiting a comprehensive range of chemical-resistant Teflon® fluoropolymers for use in chemical plant construction, focusing on bio/food technology and pharmaceutical production, on stand K 40/41 in Hall 3.0 at Achema 2003 (19-24 May). Visitors to the stand will be able to find out about antistatic Teflon® PFA C 980, the highly transparent grade PFA HP Plus, products with food contact approval and the advantages of Process G, DuPont’s new technology, as well as a whole series of new and interesting applications.
Teflon PFA HP Plus is a highly transparent fluoropolymer suitable for a variety of pipes, tubes, flanges and valve systems. Grade PFA C 980 combines outstanding antistatic properties with very good processability and so opens the way for new designs and geometries.
In Process G, the company’s own new manufacturing technology, conventional aqueous polymerisation is replaced by a process based on the use of supercritical carbon dioxide (CO2). Among the many end-use and processing advantages of the new Teflon® G grades over the previous FEP products, are improved mechanical properties, such as higher flex life, and better thermal stability. The main areas of application for these products, manufactured in Fayetteville, NC/USA, are communications technology, semi-conductor production and the automotive industry.
DuPont’s exhibition display will be accompanied by a symposium on Thursday, 22 May, at 2 pm. Experts – including specialists from DuPont and processors – will be giving presentations on the subject of ‘Managing Corrosion with Teflon®’. This event, featuring seven presentations in all, will take place in the Illusion 1 room in the CMF Congress Center, and will continue until 5 pm. The main focal points will be coating technologies, processing methods for Teflon® and successful solutions to the problem of achieving very high process hygiene.

Berstorff: Moving into sheet and film

Friday, April 4th, 2003

Mannesmann Plastics Machinery Group extrusion equipment companies Berstorff and Krauss Maffei have moved closer together with the takeover by Berstorff of Adolf Seide Engineering and the setting up of KMB (for Krauss-Maffei Berstorff) Seide Technology.
Seide is a specialist in cast film and sheet calender technology and has patents covering film cooling with metal belts, planetary calendars, post-cooling units for plastic sheet and linear smoothing units. The new company takes Berstorff into the thermoforming sheet machinery business, and extends the sheet technology available from K-M’s extrusion division. Berstorff is already involved in the specialised technical film and sheet sector, while KM Extrusion builds equipment for PVC sheet.
Seide will continue to operate independently alongside its involvement in systems and the joint sales activities of Berstorff and Krauss Maffei Extrusion.

Palram: PC sheet cooperation with Polygal

Thursday, April 3rd, 2003

The UK operations of two Israeli-based polycarbonate sheet suppliers have joined forces to improve logistics. Palram Europe has taken over the operations of Polygal (UK), which distributes from Newport Pagnell in Buckinghamshire. Palram makes multi-wall PC sheet under the Sunlite brand at a plant in Doncaster. Polygal imports similar products from Israel. By pooling resources, Polygal will replace its long-distance imports with British-made Sunlite product, and Palram will acquire both an outlet in the South of England, and a means of utilising the capacity at Doncaster which was freed up when Palram opened a PC plant in the USA - Doncaster previously supplied the American market.
Polygal also supplies specialist sheet products made in Israel under the Polygal name, and will continue to do so. Many of these will be added to the product lines distributed by Palram.

Neoplastica: New expanded PET sheet made of DuPont Bynel®

Thursday, April 3rd, 2003

Neoplástica S.A., a leading producer of PET sheets for food packaging and non-food products, relies on DuPont Bynel® adhesive tie layer to manufacture a new type of cost effective multilayer, heat-sealable expanded PET sheet, offering excellent barrier and peel properties.
The seven-layer, 100 per cent recyclable ‘Alightseal’ and ‘Alightbar’ sheets are produced in a one-step process. The granules of the different polymers (Structural, barrier and sealant) are co-extruded into a sheet which is simultaneously foamed or expanded in the same process. The DuPont Bynel® adhesive layer incorporated has the advantage of making the sealing polyethylene layer , the barrier EVOH layer and the structural polyester layer adhere to each other to form one body.
The expanded PET layer can be pigmented to produce wide range of attactive coloured trays tailor-made to customer demand, which will increase brand identification and enhance shelf appeal.
The EPET blend / PE ‘Alightseal’ sheet offers outstanding barrier properties to water vapour and medium-barrier characteristics to oxygen. It allows more than 30 per cent weight reduction, is cost efficient and can be easily thermoformed in any FFS machine. In addition, its rigidity can be adapted to a vast range of packaging needs, including applications for meat products, fish, frozen foods and desserts.
As for the EPET blend/EVOH/PE ‘Alightbar’, this special sheet also makes it possible to reduce the weight by more than 30 per cent, allows for good thermoforming, whilst offering outstanding barrier to oxygen, aromas and water vapour. The special blend is moreover cost efficient and its rigidity can be adapted to any packaging needs. Applications for the product include fresh and processed meat, cheese and poultry. In addition, ‘Alightbar’ has an improved shelf life.
Says Ricardo Berguinzo, Neoplástica’s Global Marketing Director: “Unlike its competitors, the company bases its production of multilayer APET both on the traditional process of adhesive-lamination and on co-extrusion. The latter process is more efficient as it is based on state of the art technology, delivering a customized and higher performing product. The Group satisfies customer needs through improved barrier properties, gloss, transparency, easy peel, heat resistance and correct conservation of the packed product, mainly because of the sheet structure used.”
Neoplástica S.A. makes use of the latest technology, equipment and computer control. The company’s success is based on knowledge and experience in mono and co-extruded multilayer sheets, market research, product development and customer support. It relies on a highly qualified management and personnel, a close technical and commercial relationship with raw material suppliers and with main producers of packaging machines and equipment.

Addplast 2003: Growth for wood-filled PVC extrusion

Wednesday, April 2nd, 2003

Michael Schiller, head of R&D at stabiliser supplier Chemson, told delegates at Addplast 2003 conference: “There will be more growth in Asia than Europe, because wood is not particularly expensive in Europe and in China there are millions of people but not enough wood.” The US is already an established market for wood-filled PVC profiles, mainly for decking and sidings.Chemson and a number of research partners, including PVC producer Vinnolit, have looked into the feasibility of wood-filled PVC extrusion, using lead, calcium-zinc and organic heat stabiliser systems. One encouraging aspect of the research suggests that 70% filled PVC is highly flame retardant – unlike 70% wood-filled PP.
In a separate move, HT Troplast of Germany is planning to introduce window profiles reinforced with natural fibres. It says the extra strength imparted would allow it to eliminate costly steel reinforcing bars, resulting in lower-cost window profiles.
