Abstract
Pressure and temperature fluctuations within injection molding cavities adversely impact the viscosity of injected molten polymers, leading to material defects and poor part quality. This research investigates the feasibility of wire-arc deposition through patterned masks as a cost-effective and direct method for fabricating strain gauge and thermocouple sensors directly onto cavity surfaces for accurate and real-time in situ process monitoring. Preliminary characterization of coating microstructures revealed improved density and surface splat formations in a comparative study against flame sprayed coatings. The thick film Ni-Cr strain gauge responded linearly to uniaxial tensile strains and exhibited a cycled gauge factor of 70 with a R2 value of 0.995. Furthermore, a four-point bending experiment successfully demonstrated a reduction of hysteresis with increased cycling of flexure loads. Finally, wire-arc fabrication of a steel-constantan surface thermocouple, with a 0 °C Seebeck coefficient of 50 µV/°C, was also proposed to compensate for thermal output.

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
