Technologies International (PTi), a
leading global manufacturer of high-performance sheet extrusion machinery, has
announced its showcase
system at NPE
2015: The International Plastics Showcase, March 23-27 at the Orange County
Convention Center in Orlando (Booth #W4182).
The NPE Line is an 85mm/52D HVTSE®
extruder with a GCH661824 horizontal roll stand and is capable of producing 57"
wide PET/PLA sheet at thicknesses down to 6 mil or PP sheet at thicknesses down
to 11 mil. This system, available subject to prior sale, operates at 2,300 lb/hr or a total
of 18 million lb of annual PET production. It will be the fourth installation
in the last six months, and in addition to the units sold from the 2011 launch, will
represent a theoretical installed capacity of 390 million lb of annual North
American PET production.
"We initially thought that the energy
savings and process simplification of the dryerless technology would be the
selling points, however, we've quickly seen that the equipment's resin
versatility has been the primary driver," said Matt Banach, PTi's vice
president of sales and marketing.
Systems ranging from 85 to 170mm are
capable of processing PET at rates ranging from 2,300 lb per hour (1,045 kg/hr)
to 5,500 lb/hr (2,500 kg/hr), and convert a variety of resins including post-consumer
and industrial PET/PLA, PP, HDPE, HIPS and more. The energy-efficient process
relies on High-Vacuum Twin-Screw Extruder (HVTSE®) technology, which
allows virgin or recycled PET to be processed without the need for raw material
drying and crystallizing. The "dryerless" sheet extrusion system is an eco-conscious manufacturing
solution which delivers major energy and cost savings, according to Banach. It
is a significant reduction in the carbon footprint of virgin and recycled PET
In terms of sustainability
advantages, the HVTSE® process provides a reduction of about 80-85 kWh/1000 lbs in energy consumption
versus conventional PET processing. "This savings equates to more than 31.6
gigawatt hours of annual power consumption when factored across our 390 million
pounds of theoretical installed HVTSE®
PET capacity base," said Sushant Jain, senior scientist at PTi. "The resultant
energy savings could mean a reduction in CO2 gas emissions of more
than 23 million pounds per year from fossil-fuel burning power plants."
The NPE line unit boasts several
novel features including PTi's new G- Series® configurable
roll stand. The GCH661824 three-roll horizontal system permits greater
flexibility and significantly reduced downtime for system modifications. "The
new G-Series® Horizontal
facilitates the production of some of the thinnest PET and PP thermoformed
sheet in the market," according to Banach. "The roll stand was developed in
response to market demand for high-quality, thin-gauge sheet for the production
of lightweight packaging."
Other key features include PTi's
Titan® Plus Integrated PLC control
system, multi-resin capability, rapid resin changeover, and advanced safety
PTi has a demonstration line at its Aurora, Ill.
headquarters which is available to sheet manufacturers for product evaluation
using their own virgin and recycled materials. Banach noted that customers have
the ability to run production-scale trials instead of scaling up from a small
lab-scale pilot line that can often result in inaccurate estimations and
