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].
Since F-ICT helped develop the original D-LFT
process in the late '90s and the direct-sheet-molding compound (D-SMC) process about five years ago, the organization has a proven track record of helping molders eliminate compounders and semi-finished goods manufacturers to produce their own material just prior to molding.
(The APP was formerly SPI's Structural Plastics Div.) Other news highlights of the meeting included one of the first uses of external gas-assist molding in the U.S., a new use of direct in-line compounding of long-fiber thermoplastics (D-LFT
) to make glass-mat thermoplastic (GMT) sheet, and a unique one-piece automotive grille guard with a molded-in chrome tube.
PlastiComp LLC, Winona, Minnesota USA, has announced that it has "expanded the versatility of the Pushtrusion Direct In-line Compounding technology beyond injection molding and is now able to offer customers a D-LFT
(Direct Long Fiber Technology) compression molding solution." The company explains that the Pushtrusion D-LFT
system produces hot charges of customized fiber-reinforced compound that can be transferred to the compression press and immediately pressed into finished parts, eliminating the need for GMT sheet.
Another approach is so-called direct long-fiber thermoplastic (D-LFT
) technology that involves compounding long glass with resin in-line with injection-compression molding.
* For the fast-growing direct long-fiber thermoplastic compounding and molding (D-LFT
) market, JM introduced StarRov LFTplus 474.
made their case for the potential cost savings of this "direct compression molding of LFTs" (D-LFT
Pushtrusion direct in-line long-fiber thermoplastic (D-LFT
) compounding and molding technology now has been tested successfully with carbon fibers.
RKT Kunststoffe GmbH of Kongen, Germany, is producing front-end frames for different types of VW Golfs and VW Polos using the technology of direct processing of long fiber reinforced thermoplastics (D-LFT
) that it developed jointly with Coperion Werner & Pfleiderer.
Also interesting is the first appearance among these awards of long-glass parts made by a direct long-fiber thermoplastic (D-LFT
* It's easier than ever for injection molders to get in on the action in direct compounding and molding of long-fiber reinforced thermoplastics (D-LFT
* Direct long-fiber thermoplastic (D-LFT
) compounding and molding is getting ready to expand beyond nonappearance structural automotive parts to exterior body panels.
