Abstract
Abstract This study investigates the relations between processing conditions and morphology of injection molded structural foams. The samples were produced by adjusting five process parameters (blowing agent concentration, mold temperature, melt temperature, injection pressure, and back pressure) at four different levels. The experiments were based on the design of experiments (DOE) analysis with a Taguchi method, and the results were used to determine the optimum conditions to produce high quality foams in terms of low skin thickness, small cell sizes, and narrow cell size distribution combined with low foam density and high cell density. The conclusions revealed that blowing agent concentration and injection pressure were the most influential factors. Using the optimum conditions predicted from the DOE, a validation test was performed and confirmed the results. POLYM. ENG. SCI., 2009. © 2009 Society of Plastics Engineers

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
