Injection molding management system

A control method of an injection molding management system comprising an injection molding management apparatus connected to a plurality of injection molding machines, for performing stock control management of a plurality of types of molding material comprising at least molding materials 1, 2, and 3 used for forming a plurality of kinds of molding in a plurality of injection molding machines comprising at least molding machines 1, 2, and 3 which each form one kind of molding with one or more types of molding material, the injection molding management apparatus comprising at least one processor configured to execute at least a part of the control method comprising:

• storing, for each kind of molding, molding information on usage of each type of molding material used in forming a molding;
• storing a stock quantity of molding material;
• a remaining product quantity calculating step of calculating a remaining product quantity of each kind of molding;
• a total usage calculating step of calculating total usage of each type of molding material used in the plurality of injection molding machines, based on the remaining product quantity and the molding information of each kind of molding;
• an order quantity calculating step of calculating an order quantity of each type of molding material, based on the total usage and the stock quantity of molding material;
• and
• an order placing step of issuing an ordering command of each type of molding material, based on the order quantity of molding material calculated at the order quantity calculating step, wherein
• in the total usage calculating step, a total usage of each of the molding materials 1, 2, and 3 for each of the injection molding machines 1, 2, and 3 are calculated using the below expressions (I)-(III):
• (Total usage of molding material 1)=(Usage of molding material 1 in injection molding machine 1)+(Usage of molding material 1 in injection molding machine 2)+(Usage of molding material 1 in injection molding machine 3);
• (I)
• (Total usage of molding material 2)=(Usage of molding material 2 in injection molding machine 1)+(Usage of molding material 2 in injection molding machine 2)+(Usage of molding material 2 in injection molding machine 3);
• and (II)
• (Total usage of molding material 3)=(Usage of molding material 3 in injection molding machine 1)+(Usage of molding material 3 in injection molding machine 2)+(Usage of molding material 3 in injection molding machine 3). (III)
