DIAPERCAST line for embossed film now in test-run

Monday, February 23rd, 2009

The test-run of Colines’ DIAPERCAST® for the manufacturing of cast embossed film for hygienic and diapers field is taking place in these days. It is a line of highest technology, the quickest available on the market as it reaches a production speed of 400 m/min. The line has a useful width of 2000 mm and grants a net production of 960 kg/h considering a film thickness of 20µ. The line is equipped with 3 extruder, automatic extrusion die as well as 5 layer feed-block Cloeren, gravimetric dosing system with 18 components, 6 for each extruder, thickness measurer, single face corona treatment and winder for reels dia. 600 mm. The line allows to realize 20 in-line cuttings for the production of 19 finished reels. The added value of this line lays in the cooling system on the rubber coated pressure roller which is realized with a dry technology and not a water bath one, avoiding in this way the problem standing out from this last technology. The line will be presented in Open House on February 24 and 25 at the facilities of Colines in Novara in order to allow to anybody is interested to appreciate the characteristics of this innovative plant.

New Reversible Surface Winder from Macro

Sunday, February 22nd, 2009

After 30 years of building winders, Macro Engineering & Technology Inc. introduced the latest addition to its family of surface winders, the AUTOMAX-SBG Reversible Surface Winder.
Unlike traditional gap surface winders that can only wind film in one direction, the AUTOMAX-SBG features a reversible winding mode, which allows the processor to choose whether to wind jumbo rolls with the film’s treated side in or with the treated side ut. The switch between winding directions is uncomplicated; the operator simply needs to thread the film in the opposite direction around the drum and select the appropriate winding direction on the touch screen.
The winder also features straight edge cutovers that are done without fold-over to produce rolls with flat, wrinkle-free film completely to the core. This allows the converter to utilize the entire roll and save costs from scrap. Other advantages of the AUTOMAX-SBG are the gap winding mode, programmable tension controls, fully automatic roll transfers, and an integrated shaft hoist that returns the shaft to the loading position without heavy lifting by the operator.
The winder can handle rolls up to 1.5 m (4.9 ft) in diameter and film thickness from 15 to 400 microns (0.6 to 16 mil). Winding shafts are available in 76 mm (3 inch) and 152 mm (6 inch) sizes. It will wind materials up to 3 m (9.8 ft) wide at speeds up to 200 m/min (656 ft/min).

Semi-Automatic Coiler Inspires an Audience of Thousands

Thursday, February 12th, 2009

When B+C Extrusion Systems (Foshan) Ltd., formerly known as Battenfeld Extrusion Systems (China), introduced its new designed semi-automtic coiler one and half year ago, nobody could imagine that this machine becomes the favourite of a huge audience. Spread by word of mouth (and the little help of YouTube), this coiler made its way to customers in China and around the globe. The HW1300/2 semi-automatic type of coiler is suitable for semi-rigid PO pipes of 10-32mm in diameter. The maximum speed is, with purpose, limited to 25m/min as higher speeds would naturally cause hassle to the operator during the change-over. However, the easy and convenient starting and change-over of coils does only need one person. The bobbin dimensions are ID 400mm, OD 1300mm and width 400mm.

WPC Comes of Age in Europe

Thursday, February 12th, 2009

When it comes to Wood & Natural Fibre Plastic Composite Extrusion Cincinnati Milacron Extrusion Systems leads the field globally with an installed base of over 300 extruders around the world specifically for WPC extrusion.  Cincinnati Milacron originated large conical twin-screw extruders and today is recognized as a global leader that pioneered extrusion technology for WPC extrusion.

“The European market for WPC products is poised to grow at a very rapid pace in the next years,  catapulting from the base that was established in the United States” according to Steve Jones, European Technical Sales and Marketing Manager for the company.   Building on the enormous amount of experience and expertise gained in this market in the US Cincinnati Milacron has installed plants with from one extrusion line running at a modest 300-400kg per hour to multiple line plants that run over 1300kg per hour per line.

Wood-plastic composites are attracting more and more companies in Europe because of the advantages the product has in high moisture applications and the growing market size.  “Many companies mistakenly believe that making a composite product is as simple as mixing PE or PP materials with some fibre filler along with some minor additives and going to market” says Jones.  “While our Plug&Play raw material system handling, mixing and delivery system simplifies the process substantially, you have to put good ingredients in the machine to get good end product out”.  This was the theme of a technical presentation that Jones made at the recent AMI WPC conference in Vienna, Austria, outlining the impact of moisture in the process and the use of uncontrolled recycle material as the polymer.

One of the issues in Europe currently is that the market started primarily as indoor applications with very high concentrations of wood fibre as filler, as high as 70 to 80%.  This has created somewhat of an obstacle in the market for exterior products in that manufacturers look to use this same level of fibre in these applications, which will create performance issues with the end product due to moisture absorption.  Because the WPC market started with decking in the US, formulations from the start have contained at the very most 55% fibre for these outdoor applications.   At that level, you get a proper distribution and a good interlock of the wood flour in the polymer matrix.  “At higher levels the fibre will get wet, swell, and split open.  This is something not everyone understands” says Jones.

Challenges for companies looking to enter the WPC market include the capital equipment cost and lack of experience with processing extruded composite products.  Cincinnati Milacron has developed the WPC Plug&Play extrusion system that is a scaled down version of larger systems installed in plants built for high-volume production. ‘Basically, it can do what the plant-engineered systems do, but without the volume and without the larger costs associated with these systems. Plug&Play is a compact system that involves a much smaller capital outlay’ says Jones. ‘It’s a chance for customers to enter the market with the assurance that the material is going through the extruder in the correct way and part of the system is customized raw ingredient evaluation and recommended starter material formulations.”  The process is relatively straightforward using the Plug&Play system.  Polymers, natural fibre and additives are pre-blended in this system and then agglomerated as an inline process.  This is necessary to produce a uniform formulation for the process.   The agglomerate is then dried in a dryer, again as part of an inline process, and then fed to the extruder for melting, mixing, venting, homogenising and pressure generation to push the material through the die. The plastication and mixing process is carefully controlled to ensure the fusion of all additives and consistent distribution of the natural fibre.  Venting is extremely important to remove volatiles and entrapped gas, as residual moisture must be removed before the material enters the die. Extruded products are then cooled in a high intensity spray cooling system instead of the conventional bath water tank, for more effective cooling and then cut to length. The Plug&Play System is available as a 1000 kg and 2000kg per hour system.

Macro’s Binary Air Ring System Boosts Output

Thursday, February 12th, 2009

Macro Engineering & Technology Inc.’s D10-B Dual Lip Binary Air Ring System has been shown to boost blown film production output by more than 30% while also improving product quality. Macro was the first to develop the binary cooling process, receiving its first patent in 1984. Initial observations indicated output improvements of 30-100% over single air ring systems along with vast improvements in gauge and clarity of the film. Since then, Macro has made continuous improvements to the binary air ring system including the integration of a patented conical IBC in 1996, which was found to improve cooling efficiency and bubble stability. Macro’s most recent trials on its 3-layer R&D line running at 450 kg/hr (1000 lbs/hr) generated outputs of 2.25 kg/hr per mm of die diameter (40 lbs/hr per circumferential inch).

Since its development 25 years ago, Macro’s binary air ring system has been installed at multiple extrusion plants around the world including 20 systems delivered in 2008. The D10-B is primarily sold as a stand-alone system offered through Macro’s Retrofit Division to improve output and product quality on all makes of blown film lines; however, the system is also available as part of a high output package for Macro’s BXL Series of blown film lines.
