After that, cut the plastic sheet into suitable size according to the size of the egg tray molds, and then place the sheet with suitable size into the heated wooden cabinet and fix it completely, and then the wooden cabinet and plastic sheet are placed on a constant temperature furnace for softening treatment.

Third, Put the softened plastic sheet together with the wooden cabinet in the vacuum chamber, turn on the suction switch, and suck the air in the vacuum chamber clean. After the plastic sheet cools, you will get the same concave egg tray as the mold.
