Abstract
The effect of weld lines on the mechanical properties of structural high density polyethylene foams was studied. Injection moulding was used to produce foams using azodicarbonamide in single and double gated moulds where shot size, injection speed, and flow direction were changed. The mechanical response of the foams was characterized in tensile and shear tests. Density reduction, decreasing injection speed, and the presence of the weld line were found to reduce both tensile and shear moduli, as well as tensile strength, break strain and toughness. The lost of mechanical properties can be related to lower skin thickness and incomplete bonding at the weld line. Simple correlations are also presented to predict moduli and strength of these foams.

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
