Abstract
Typical thin-wall cylinder castings and technical requirements were introduced. The foundry defects on cold core,inner and outer surfaces of cavity on the cylinder were elaborated. To prevent the inner cavity of water jacket from breaking,special sand was used instead of silica sand. Improved water jacket sand core coating process and acidity regimentation were also used to increase the sand core strength. To prevent sand inclusion defect on outer wall of water jacket,bentonite was used and thermal radiation time of outer wall on upper box water jacket was decreased. To prevent burnt-on sand defects,the sand grain size was refined and porosity resistance was increased. High air back pressures can keep melt from running into the sand gap. Adjustment of re-used sand temperature and moisture can reduce thermally bonded sand. These parameters also reduced the sand defects. To prevent sintering defects,small size of screws were used. And using special mixed sand,reducing the oil core drying temperature and round radius,improving paint formula are also helpful.

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
