Davis-Standard: Groove Feed Technology to all Product Lines

Tuesday, April 13th, 2004

Due to impending demands, Davis-Standard has further developed its groove feed extruder line to support a range of blown film, blow molding, sheet, pipe and profile, and wire and cable applications. Advances in both groove feed bushing and screw design have allowed Davis-Standard to provide processors with increased throughput and improved polymer homogenization at reduced melt temperatures. The majority of Davis-Standard’s groove feed customers have increased outputs by 40 percent, and in some cases outputs have doubled.

Groove feed extruders, available in 2- to 6-inch (50 to 150mm) 34:1 L/D sizes, include a wear resistant, unitized groove feed housing with a removable and replaceable groove feed bushing. The bushing is available in multiple groove designs for processing a range of thermoplastic materials including PP, PVC, polyolefins and various engineered resins. Aggressive, rectangular grooves are available for stiffer polyolefin materials as well as milder, ratchet-style grooves for softer materials such as flexible PVC.

On the feedscrew side, Davis-Standard’s patented DSB®-VI barrier screw is specifically designed for high throughputs and incorporates a dual barrier with a variable lead barrier flight. The DSB-VI minimizes wear within the aggressive groove feed environment and improves stability in head pressure and melt temperature. Wider channels accommodate larger outputs and provide a 40 percent increase in melting capacity when compared to conventional barrier screws. Additionally, this design has provisions to fit several mixing sections to the screw for the production of uniform melt properties to consistently disperse additives and polymer blends.
Davis-Standard recently installed a 3 1/2-inch (90mm) groove feed laboratory line at its Technical Center in Pawcatuck, Connecticut, to support customers and demonstrate groove feed advantages.

Deceuninck: Increased profits in new markets

Monday, April 12th, 2004

PVC windows maker Deceuninck Group recorded increased profits last year after expanding into new markets. Profits for the Belgium-based company rose 17.5% compared with the previous year to EURO 91m. Sales were up 29.9% at EURO 470m. Deceuninck said a strong renovation market helped its performance. The largest growth for the company was in eastern Europe and Turkey. Deceuninck expanded into the Russian market last month and opened an office in Moscow. It employs over 30 staff in the country. Despite its US operations being hit by a weak dollar and high PVC prices, the firm last week started production of wood composite decking boards in Ohio. Deceuninck said it expected to expand into new geographical areas over the next year.

Battenfeld Gloucester: New Slitters Contribute to Conversion Quality Trimless Rolls

Monday, April 12th, 2004

Trimless rolls, those produced without removing the edge of the film before it is wound, can be a real challenge. The material and cost savings that result from the lack of edge trim, can make it an enticing niche to some film manufacturers. Producing quality film, at the highest possible first pass yield, for converting operations makes the difference between success and failure in many markets. The rolls need to be flat, smooth, compact, tight from end to end, and ready for high speed printing and converting. Reliable equipment and a stable bubble are critical. This is where Battenfeld Gloucester’s blown film lines contribute to this success.

Between the die and the top of the tower, a number of Battenfeld Gloucester technologies maintain the optimized quality of the film exiting the die. The user friendly UltraCool Air Ring is easy to adjust with repeatable settings. The system is very stable. Even with difficult to process materials and structures the end result is less bubble breathing and fewer wrinkles.

The automated start up function of the Digisonic™ IBC (Internal Bubble Cooling) Control System helps ease thread up and faster product changeovers. Optimized hardware configurations and sophisticated control algorithms enhance maximum bubble cooling while minimizing gauge variations (thick/thin areas).
A contact style Bubble Cage with fully teflon surfaced rollers and composite roller collapsers helps minimize layflat variation while minimizing the effects of friction and temperature for those products that will tolerate contact. BGE offers alternative non contact cages and collapsing frames for ultra critical products.

The Oscillating Hauloff at the top of the tower randomizes any remaining gauge imperfections.
Before actual winding, the film tube is slit by the Trimless Edge Slitter Station. The new high quality slitter design features a lower blade that faces upward towards the inner shoe. The film “walks” down the blade, pulling tension on the film, making for a better cut. The dimpled teflon-coated surface allows the film to float better with less air volume, preventing a “pillowing” effect above the blade holder. Less film pillows mean better layflat control and fewer edge wrinkles.

The precision and stability of the Model 1008 phantom axis dual turret winder with loadcell tension control is the final assurance of perfect edges and tight smooth rolls.

Advantages of producing trimless rolls:

• resin savings
• scrap elimination
• layflat accuracy
• scratch- and stretch-free films
• improved roll geometry
• higher converting speeds

Borealis: Greater profitability with CleantainerTM delivery of SupercureTM LE8201

Tuesday, April 6th, 2004

The manufacture of XLPE power cables has risen by more than 25% over the past five years. And, as the demand for power increases and earlier generation technologies such as paper cables are replaced, the growth rate in volume is certain to rise higher. This will create two challenges: the need for increased manufacturing productivity and an improved delivery system to move product to the customer.

To meet these challenges, improved logistics will be needed to deliver high quality materials to extrusion facilities. To date, the method used to transport cable materials has been the one tonne box, which is filled and emptied under clean room conditions. However, to handle the higher delivery quantities that will be demanded in future by the cable industry, a new bulk delivery technology has been developed.

Meeting greater demand for cable, without recourse to capital investment in an additional Catenary Continuous Vulcanization line, can be achieved through higher line speeds. But in very many instances the productivity of a medium voltage cable making facility is held back by the crosslinking speed of materials. Where this is the case, Supercure LE8201 can provide the solution. This material has an advanced crosslinking mechanism that enables the crosslinking to be carried out more efficiently. In practice this can mean cable lines running as much as 30% faster, and therefore yielding a 30% increase in volume.

Cleantainer delivery and Supercure LE8201 provides a unique fusion of complementary technologies. As line speeds increase with the use of Supercure LE8201, the supply of materials, in sufficient quantity and in clean room-acceptable condition is conveniently addressed by Cleantainer. Together these new technologies can make a very significant contribution to operability, productivity and ultimately profitability.

Cleantainer, the new bulk delivery technology, is among the new, advanced wire and cable solutions, which will be presented at the Borealis Stand at Wire 2004, D70, Hall 10.

Borealis: Supercure™ LS4201 improves productivity for XLPE cable manufacture

Monday, April 5th, 2004

To help satisfy the growing demand for MV, HV and EHV underground cable systems for electric energy transmission, Borealis, the leading supplier of polyethylene to the wire and cable industry, has developed Supercure LS4201. The new XLPE compound can deliver significant increases in cable production speed without compromising either quality or performance.
Supercure LS4201 is a further development of Borealis’ well-established LE4201, the current industry standard for XLPE cable. It can improve productivity in the two main areas of degassing and extrusion.
Degassing is an important process for HV and EHV cables as it removes the cross-linking by-products such as methane, which otherwise would present a number of problems if left within the XLPE matrix. The time taken to degas a cable primarily depends upon the initial level of by-products. Traditionally the process has been accelerated by increasing the temperature, which speeds up degassing but also uses significant amounts of energy and can cause damage to the cable core. Supercure LS4201 reduces the degassing requirements and thus can significantly improve cable productivity.
Supercure LS4201 cable insulation was engineered to enhance performance in respect of improved length of run (lower propensity for scorch), reduced degassing and to maintain or increase extrusion speed. The scale of productivity improvements that can accrue from the increased throughput offered by Supercure LS4201 (increased length of run at essentially identical line speeds) will depend on cable design, size and manufacturing principles, but at 12mm wall thickness production time can be reduced by 25% or more.
Supercure LS4201 is among the new, advanced wire and cable solutions, which are presented at the Borealis Stand at Wire 2004, D70, Hall 10.
