The mold temperature controller heats or cools the heat medium (usually water or oil) and circulates it to the mold to maintain the mold within a specific temperature range.
When the mold temperature is lower than the set value, the heating system of the mold temperature controller starts and heats the heat medium to the required temperature. When the mold temperature is higher than the set value, the cooling system of the mold temperature controller starts and cools the heat medium to the required temperature.
