摘要	A method of operation for an apparatus for making an upper and a lower mold and the apparatus therefore that can prevent a mold from having a-wrap or a match plate from being damaged. The apparatus for making an upper and a lower mold of the present invention controls the forward movement of an upper and a lower squeeze member such that when they each move forward to the match plate by means of the squeeze means of the upper and lower molds the difference in the squeeze forces imparted by the upper squeeze means to the upper squeeze member, and the squeeze force imparted by the lower squeeze means to the lower squeeze member, is kept within the predetermined tolerance.
