Brampton: Water-quenched Coex PE film

Wednesday, October 31st, 2001

Water-quenched, downward-extruded bubbles are common for polypropylene, but this is probably the first system of its type for eight-layer polyethylene film. Called AquaFrost, it was developed by Brampton Engineering Inc. in Brampton, Ont. to make very high-clarity packaging films for thermoforming. Water cooling quenches the film to the same clarity, orientation, and deep-draw formability as cast films, Brampton says. The first prototype, capable of five to 10 layers, is in Brampton’s test lab.

Boston Matthews: New extrusion technology

Tuesday, October 30th, 2001

Boston Matthews will launch a number of new developments with the clear emphasis on using technology to provide the processor with accuracy and information/data about their extrusion process. These include a new range of extruders which incorporate the brand new computer control system – ExtruPro®. Additional machine launches include a new range of Precision Servo-Rotary Cutters for accurate high speed cutting. Also being demonstrated will be the All-Electric Servo-Driven Saw which eliminates the need for any secondary off-line cutting; and the Industry Standard Model ‘C’ Caterpillar Haul-Off now fitted with AC Flux Vector Drives as standard. The new extruders are fitted with an AC Vector Drive as standard giving the user such benefits as lower operating costs; lower maintenance costs; increased speed holding capabilities and improved torque characteristics.. The new extruder range is available with a new computer control system – ExtruPro. The new extruders can be linked directly to a modem for ‘Remote Customer Support’. This enables Boston Matthews technicians to trouble-shoot the machine no matter where in the world it is located.

Theysohn Maschinenbau: Twin Screw Compounder at K

Monday, October 29th, 2001

Theysohn Maschinenbau has engineered a new TSK-PCE range of twin screw compounders including the Laboratory TSK 20 table top design, and a 5000 kg/h compounder. With the TSK 20 PCE Laboratory Compounder, a 20 mm twin screw has been developed for colour matching and formulation development. The electrics are integrated in the base of the compounder, thus the space required is minimal. The TSK 48 PCE (400-500 kg/h) has been designed as a compact mobile unit. The compounder, feeder, and premix container from the change bowl premixer are integrated inside a mobile steel platform. This completely wired and pre-tested line requires no further installation, and can be put into production within a few hours of delivery.

Tredegar: Closing of film plant

Friday, October 26th, 2001

Tredegar Film Products Corp., USA, will close its Tacoma plant because of changes in hygenic-film supply and demand. Tredegar said in an Oct. 15 news release that demand is declining for Tacoma´s embossed film for diaper backsheets. Meanwhile, expanded production capacity in China will supply Asian markets when Tacoma shuts down by the end of April, cutting 45 jobs.

Welex: 1100 kg/h packaging sheet line

Friday, October 26th, 2001

At K 2001 Welex will be exhibiting a 1100 kg/hr APET packaging sheet line sold to Vitembal, France. The exhibiting line will feature the new 130 mm 30D Mark III vented extruder that will run via the Welex V-PET system, which significantly minimises the need for predrying PET. This complete turnkey system is the newest member of the Welex World Standard family of complete hopper-to-winder sheet extrusion systems. This size was developed specifically to satisfy the rising demand for lines to produce one ton per hour of quality thermoforming sheet. The same line can also run HIPS at similar capacity, or PP at a lower capacity, without any changes.

Davis-Standard: Precision with functionality

Thursday, October 25th, 2001

Davis-Standard’s DSC-U2 heavy duty servo cutter is designed for accuracy, flexibility, and simplified programmability.

Cutter advantages include five different cutting modes, variable knife speeds from 500 to 1200 rpm, pre-settable length, and a batch counter. The five cutting modes include: Flywheel/Master mode, Flywheel/Slave mode, On-Demand/Timer mode, On-Demand/ Encoder mode, and On-Demand/External mode. The DSC-U2 operates on a centreline of 1,066 mm on tracks, and includes a heavy duty table, V-groove castors with brakes, and a spray lubrication system.

Huntsman Tioxide: New masterbatch grade

Thursday, October 25th, 2001

Huntsman Tioxide will officially introduce its new grade Tioxide TR28 at K 2001. Tioxide TR28 is the latest development in Huntsman Tioxide’s innovative approach to supplying products for the masterbatch industry. It has been specially designed to meet the most demanding requirements of masterbatch producers and offers an even higher performance than its predecessor Tioxide TR27. Tioxide TR28 offers a wide range of benefits for masterbatch processing techniques such as co-extrusion, extrusion coating, cast film, and blown film. Mineral and organic coatings have been specially designed to minimise the emission of the volatiles which contribute to problems such as die build-up and, in extreme cases, lacing.
