During the D-LFT
process, which includes an oven to dry the material, two extruders, a conveyer and a press, there are three types of degradation mechanisms PA6 has the potential to undergo: thermal [3, 16], mechanical , and thermooxidative [3, 17].
SFT competes with a wide range of materials, including long fiber reinforced engineering plastic, glass mat thermoplastic(GMT), sheet molding compound/ bulk molding compound (SMC/BMC), D-LFT
The LGF screw is said to be compatible with either D-LFT
(in line compounding) processes or molding precompounded long-glass pellets.
But he adds, "It is clear, based on the number of D-LFT
machines sold, that the direct process has and will continue to gain a major share, especially among large processors with long runs.
These heavy-duty functional parts are produced by means of a D-LFT
process at RKT Kunststoffe's new plant in Curitiba, Brazil.
At the recent NPE show in Chicago, two familiar names in injection molding machinery introduced standardized equipment options for a patented D-LFT
process that is said to be less expensive and simpler to operate than other D-LFT
The move also involves a switch from polyolefins, which have been the mainstay of D-LFT
composites, to styrenic thermoplastics.
Steve Bowen, president and CEO of PlastiComp, and Ron Hawley, Woodshed president and inventor of the D-LFT
technology, agreed that PlastiComp will hold exclusive global marketing rights for Woodshed's D-LFT
One machine in North America is used for D-LFT
with long glass.
in 1989 to mold D-LFT
parts and license the process.
It's a rare opportunity to meet and mingle with dozens of innovators in D-LFT
and other long-fiber thermoplastic technologies, such as extrusion of structural profiles.
PLASTICS TECHNOLOGY is organizing a two-day conference on D-LFT
technology at the Marriott Biscayne Bay Hotel in Miami, Fla.
