RHEOLOGY:
The material's rheological behavior was tested by the manufacturer by an unspecified test method. Data was last updated on 28-JUN-01.
THERMAL:
The material's thermal conductivity was tested by the manufacturer by an unspecified method. Data was last updated on 01-JAN-99. Thermal conductivity was established at a single temperature.
SPECIFIC HEAT:
The material's specific heat was tested by the manufacturer by an unspecified method. Data was last updated on 01-JAN-99. Specific heat was established at a single temperature.
pvT:
The material's pvT data was tested by the manufacturer by an unspecified method. Data was last updated on 23-MAY-01.
SHRINKAGE (MIDPLANE & FUSION MODELS ONLY):
For this material, shrinkage and warpage predictions will be based on an uncorrected residual stress model with generic estimates of material mechanical properties. Data was last updated on 21-APR-2003.
Analysis of approximately 895 mold trials on 35 unfilled ABS materials showed:
In the direction parallel to flow, 73% of shrinkage predictions from simulations with data such as this were NOT within 25% of experimental values. In contrast, 88% of simulations with CRIMS data were within 25% of experimental values.
In the direction perpendicular to flow, 68% of shrinkage predictions from simulations with data such as this were NOT within 25% of experimental values. In contrast, 84% of simulations with CRIMS data were within 25% of experimental values.
You can achieve more accurate shrinkage predictions by using measured shrinkage data and Moldflow's CRIMS model.
