In Order to Maintain Fiber Length Throughout the Molding of LFRTS, there are three important areas to consider: the inject moducting machine, part and tool design, and procested contenting
Equipment Considerations
Equipment is adequate for most lfrt parts and propucts, some equipment modifications can be made to help preserve fiber length.
BREAK down the Fibers.
Part and Tool Design
, as well.
), with a minimum Thickness of 2 mm (0.080 in.). Wall Thickness THAN THAN 2 MM Increase the Probability of Fiber Breakage After Has Entected the Tool.
They are not properly designed.
To the Glass-Fiber Reinforcement During Molding. Open Channel Hot-Runner Systems Are Acceptable.
And Reducing Mechanical Performance.
Are expected to be lower.
One strays from the recommendations, the more time and effect will be required to enter that the full benefit of long fiber technology.
Processing Conditions
1.5 to 2.5 Bar (20-50 PSI) is typically enough to get consistent feeding.
Speed at the Minimum Level Required to file the scream. Screw Speeds of 30 to 70 RPM are common when molding comprt compounds.
Not uncommon for lfrt compounds to be processed 10-30 ° f higher than conventional molding compounds.
Will Soften and Melt the LFRT PELLETS BeFore The Enter the High-SHEAR Region of the Screw & RSQUO; S Compression Zone.
