Abstract
The influence of density of polysterene foam models on the quality of thin-wall castings of the cap of the gas analyzer case made of AK7 alloy smelted based on wastes of home manufacture (the charge contained 50–55 % secondary materials) is investigated in conditions of LLC SPE «Vektor Mashinostroeniya» (Novokuznetsk). To foam polysterene (produced by «STYROCHEM», Montreal, Canada) and fabricate the models, a GK-100-3M autoclave was used. Varying temporal-and-time autoclave modes, we obtained different densities of the model ρ = 0,017, 0,019, 0,022, 0,024, and 0,026 g/cm3. Based on the experimental investigations, the values of this index (ρ = 0,022÷0,024 g/cm3), at which the model possesses the required surface quality, stiffness, and burnability promoting the minimization of linear defects (mismatch with required geometric sizes, seal, misrun) when fabricating thin-wall casts with specified properties, are determined and substantiated.

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
