After the first controller 22 energizes and heats the conductive heating layer 23, the conductive heating layer 23 conducts heat to the plurality of workpieces 40.
As shown in fig. 1, the temperature adjusting system 30A is combined with the two pressing plates 10 to heat or cool each pressing plate 10, and is provided with a main body 31A and two pipelines 32A.

Each output tube 35B is connected to the fluid outlet 12 of the flow channel 13 of one of the pressing plates 10 and is communicated with the flow channel 13 of the pressing plate 10, and each output tube 35B is communicated with the input tube 34B of the pressing plate 10 through the flow channel 13, so that the fluid flows into the pressing plate 10 through each input tube 34B and the fluid inlet 11 of the corresponding flow channel 13 of the pressing plate 10, and then flows out of the pressing plate 10 through the fluid outlet 12 of the flow channel 13 of the pressing plate 10 and the corresponding output tube 35B.

Then, the temperature adjusting system 30B assists to heat the plurality of workpieces 40, the second controller 36B activates each heating element 33B, so that each heating element 33B heats the corresponding pressing plate 10, the conductive heating layer 23 further conducts heat to each workpiece 40, and thus, a high temperature pressing operation can be performed on each workpiece 40, and the temperature of each workpiece 40 during the high temperature pressing operation is raised to the position of X on the vertical axis in the temperature variation diagram, i.e., about 200 ℃, as shown in fig. 9. After each workpiece 40 is pressed and molded, the plurality of heating elements 33B are turned off by the second controller 36B, and then the room temperature fluid is continuously input to the corresponding press plate 10 through each input pipe 34B, so that each press plate 10 can be cooled by the room temperature fluid, the temperature of each press plate 10 is reduced to 40-60 ℃, and further each workpiece 40 can be cooled, and the temperature is reduced from about 200 ℃ to the position of Y on the longitudinal axis in the temperature change diagram, namely, 40-60 ℃ as shown in fig. 9.
