Molding compound parts with uniform wall thickness are precisely and repeatedly produced by compression, though supporting rods and levelling devices used for supporting the platen of press equipment which tilt during compression. The press equipment of the present invention is provided with levelling devices for supporting the platen at the four corners on the bed. The supporting rods of the levelling devices are hollow, with position detecting means vertically mounted therein so that the height of the supporting rods can be precisely detected and the rods can be synchronously controlled so as to make the upper mold half parallel to the lower mold half of the mold without magnifying the error caused by the inclination of the supporting rods.
