Abstract
A method for continuously manufacturing molded products by repeating a plurality of molding cycles includes, in each molding cycle, filling a resin composition into a mold, pressing the resin composition in the mold, cooling the resin composition in the mold using cooling water, and releasing the resin composition from an interior of the mold to obtain a molded product. An A-th molding cycle of the plurality of molding cycles can be a delay cycle delayed from a B-th molding cycle. When the A-th cycle is the delay cycle, the flow rate of the cooling water flowing in the mold at the cooling step is decreased in the A-th cycle as compared with the B-th cycle.
Claims20
A method for continuously manufacturing molded products by repeating a plurality of molding cycles, each of the plurality of molding cycles comprising:
- filling a resin composition into a mold;
- pressing the resin composition in the mold;
- cooling the resin composition in the mold using cooling water;
- and
- releasing the resin composition from an interior of the mold to obtain a molded product,
- wherein, assuming that one molding cycle of the plurality of molding cycles is an A-th molding cycle, and another molding cycle different from the A-th molding cycle is a B-th molding cycle, the A-th molding cycle can be a delay cycle delayed from the B-th molding cycle, and
- wherein, when the A-th cycle is the delay cycle, a flow rate of the cooling water flowing in the mold at the cooling step is decreased in the A-th cycle as compared with the B-th cycle.
