If using Cartridge Heaters the thermocouple has to be placed on the same axis as the Cartridge Heaters and has to be centered between two heater holes. The tip should be as close to the cavity and core inserts as possible, if a thermocouple is placed perpendicular to a heater then the tip will measure the heater and give a false reading for the cavity and core.

Thermocouple placement is imperative if the mold has cal rod heaters as you probably have for your rubber and thermoset molds. For oil heated molds, thermocouples are nice but not an absolute need.
