This invention discloses a production method of inflatable toy. The first step is to prepare hard PVC powder and soft PVC paste resin. The second step is injection moulding of embedded parts and grasp parts. The third step is preparation of slushing mold or rotational molding mold. The fourth step is shaping of soft PVC paste resin. The fifth step is cooling and demoulding and then air inflation for modeling. The sixth step is installation of grasp parts and inspection and testing of qualified products; in this invention, the secondary forming of hard PVC embedded parts made through injection moulding, are moulded in soft PVC rubber part itself through rotational molding or slush molding in the rotational molding mold or slush molding mold. And then, the grasp parts and embedded parts are firmly connected through buckle or screw. The design has solved the problem of location design of the circular handle, which is unable to be installed in parts other than the joint line through traditional PVC rotational molding mold or slush molding mold. It has perfectly realized the grasp function. In addition, the installation of formed ears or other injection-moulding parts guarantees no deformation of the parts, and this presents a good revivification of product design.

A sealing member for a powder slush molding apparatus includes an elastomeric main body comprising a head portion, an anchor portion, and a neck portion extending between and joining the head portion and the anchor portion. The head portion of the sealing member defines at least one interior channel that is centered on a midline of the elastomeric main body and which has a polygonal sectional shape. The polygonal sectional shape of the at least one interior channel, and its location on the midline, permits the head portion of the sealing member to attain a measure of compressibility that helps limit the force needed to compress the head portion without rendering the sealing member too flexible that it cannot adequately retain its shape. The sealing member is useful in establishing a seal between a shell and a powder box of a powder slush molding apparatus.
