이것에 의하여 수지성형체의 표면 전체에 걸쳐 피복재료를 균일하고 양호하게 피복할 수 있다. 분할형이 구비되고, 외주이고 미끄럼운동가능한 위치에 테이퍼부를 형성한 양자간에 공간을 형성가능한 형을 사용하여 성형소재를 압축성형하여, 완전경화전에 형을 서로 떨어지게 하여, 성형체의 적어도 한쪽면과 이때 대면하는 형의 면의 사이 공간을 구획하고, 이 공간을 통하여 형밖으로 이물질을 내보내도록 형내에 그 외주방향을 향하는 가스흐름을 형성시켜,유동성 코팅제를 성형체와 형면의 상기공간에 주입함과 동시에, 다시 형을 죄어 가압경화 시킨다. This invention enables the outer surface as a whole of a molded resin product to be covered with a coating material with uniform and satisfactory tension. A split mold is provided, which is capable of forming a hollow space between the tapering portions at the circumferential and slidable parts of upper and lower mold members thereof. A molding material is compression molded by using this mold, and the mold members are separated before the molded product has been completely cured, so as to form a space between at least one surface of the molded product and the opposed surface of a mold member. A gas flow directed toward the outer circumference of the mold is formed in the mold so as to send out the extraneous matter to the outside thereof via the mentioned space, and a fluidized coating material is injected into this space between the molded product and the opposed mold surface. The mold is clamped again, and the resultant product is cured under pressure.
