However, the mold or the heater block may be deformed by heat, so that the upper surface of the upper mold and the lower surface of the upper heater block may not come into close contact with each other or may be in close contact with uniform pressure. Measure the adhesion between the upper surface of the upper mold and the lower surface of the upper heater block, and forcibly fix the pressure unit by putting a shim suitable for correcting the adhesion to the fixing unit of the pressure unit to which the upper heater block is coupled. The upper surface of the upper mold and the lower surface of the upper heater block are in uniform contact with the entire mold.

However, the method using the pressure-sensitive paper is not easy to measure the adhesion between the two planes, it is very difficult to measure the adhesion when the two planes are not parallel to each other. In addition, after measuring the adhesion between the two planes and accordingly adjust the two planes parallel to measure whether the adhesion has been improved again, the process of removing or adding 까지 until a satisfactory adhesion is achieved, so that many It takes time and the method is complicated.
