PURPOSE:To reduce the occurrence of voids in a molded product by causing the tablets made of thermosetting resin to flow into, pushing said tablets with the tip surface of th plunger with a convex shape. CONSTITUTION:The tip surface-shape of a plunger is formed inot a convex shape. When a package 8 is molded by such a transfer moding, the plunger 7a pushed tablets 6. When the tablets 6 become a fluid, the bubbles 11 formed in a gap 10 gather upwardly and reduce the air amount dragged into the molding material flowing into a runner. Accordingly, the voids occurring in a molded product are remarkably reduced, an for instance, the occurrence of inferior products is reduced in the package molding of mold IC. |
