First-term flat-wall conduction estimate. Enter grade-specific thermal diffusivity; the default is a hypothetical arithmetic example, not validated material data.
Enter and review the parameters, then calculate. The fixed example below is not your current result.
t = h²/(π²α) ln[(4/π)(Tm−Tc)/(Te−Tc)]. Requires melt > ejection > coolant. α is user-entered in mm²/s; obtain temperature-appropriate data from the material supplier. Flat-wall, constant-property, perfect-contact approximation only; crystallization, mold temperature variation and the rest of the molding cycle are excluded. Sensitivity rows are limited to the same ordered-temperature domain. This is mathematical estimation, not production-cycle validation.
Hypothetical fixed example: h=2.5 mm, α=0.08 mm²/s, melt=230°C, ejection=80°C, coolant=25°C gives 12.326682 seconds. At h=3 mm it gives 17.750422 seconds. These example properties are not a resin datasheet.
