Brampton Engineering Inc. will be running hot and cold at K 2004, as the blown film equipment maker shows products called Heated Lip and AquaFrost.
The Brampton-based company announced that, after nine months of beta-test trials on a customer's nine-layer die, it has sold two AquaFrost lines - one for nine-layer film and the other for 10-layer film - to undisclosed blown film producers in Europe.
AquaFrost uses water as a cooling medium, to produce clear, soft film with a high level of clarity, balanced orientation and deep-draw thermoformability at a high output rate, according to Brampton. Unlike conventional blown film, the bubble is blown downward through an AquaRing, which quickly cools the molten plastic and creates very clear film.
Brampton Engineering introduced the concept of the AquaRing at the 2001 K show.
At K 2004, the company will roll out the I-Flex Heated Lip, which gives die control when making conventional blown film. The Heated Lip provides a localized heated lip that reduces heat migration between zones, extends dwell time and yields optimal control when running film at high speeds, the company said.
A programmable-logic controller runs the on-off cycle for the heaters, ensuring consistent heat to each zone to produce flat film.
Brampton also will show the SCD-3, an improved version of its Streamlined Coextrusion Die. The stackable die isolates temperatures between layers, thanks to its modular design.
Another new-generation product is Italycs-4, which stands for ``integrated temperature and line yields controls.'' It monitors melt temperature and controls the bubble cage, line speed, nips and the oscillating table. Italycs-4 can be used for multilayer lines up to 10 layers, used as a stand-alone station and at a pendant-mounted station near the die or at another location.
