PROBLEM TO BE SOLVED: To prevent the occurrence of voids due to the entrainment of air among granules at the time of sealing in use of resin of powder, granule, etc., solve drawbacks regarding a sealing process such as wire flow or non-charged failure, miniaturize the size of the device, and shorten sealing cycles. SOLUTION: The device includes a screw 8 movable toward and away from a plunger part 6 for forming a pot portion 7 being a part of the sealing device. Then, granular resin 9 placed at the tip of the plunger part 6 is melted by heat of a mold 1 or the like, and then it is compressed to be concentrated in density by movement of the screw 8 before kneading. As such, an entrainment of air is reduced in molten resin. |
