본 발명은, 수지 성형 시에 있어서의 수지 찌꺼기의 발생을 억제하는 것이고, 하부틀(2)의 포트(21) 내에 수용한 수지 재료(J)를 플런저(51)에 의해서 상부틀(3)의 캐비티(31) 내로 밀어내는 것에 의해, 성형 대상물(W)을 수지 봉지해서 수지 성형품(P)을 제조하는 수지 성형품(P)의 제조 방법으로서, 포트(21)의 내면과 수지 재료(J) 사이에, 수지 재료(J)가 밀려나오는 방향을 개방하면서 수지 재료(J)를 둘러싸는 피복체(7)를 배치하고, 피복체(7)로 둘러싸인 수지 재료(J)를 플런저(51)에 의해서 캐비티(31)로 밀어낸다. The present invention suppresses generation of resin waste during resin molding, and is a method for manufacturing a resin molded article P, the method comprising pushing a resin material J accommodated in a pot 21 of a lower die 2 out into a cavity 31 of an upper die 3 through use of a plunger 51 to thereby conduct resin-sealing of a molding object W and manufacture a resin molded article P, wherein a covering body 7 that surrounds the resin material J while being open in the direction in which the resin material J is pushed out is positioned between the inner surface of the pot 21 and the resin material J, and the resin material J surrounded by the covering body 7 is pushed out to the cavity 31 by the plunger 51.
