First, the lead frame before resin sealing is positioned on the lower template of the two upper and lower templates using positioning pins. Next, after the mold is clamped by both upper and lower mold plates, a resin tablet is inserted into the pot of the mold plate and pressurized with a plunger. At this time, the resin tablet is heated and melted to become a molten resin, which is filled into the cavity via the runner and the gate. After that, the mold is opened and the molded product is taken out.
