Molding a hollow shaped body which has a skin made of a synthetic resin and a hollow portion therein by a mold block provided with a mold cavity in the shape of the hollow shaped body, a tub into which an excess amount of the synthetic resin can flow and a small flow path communicating between the mold cavity and the tub. The process includes forming the skin of the hollow shaped body by injecting a molten synthetic resin into the mold cavity to fill up the cavity. Thereafter, a gas is introduced into the injected synthetic resin to thereby form the holl...
A method of molding a molding strip having a main frame and an end cap with a hollow portion therein, which comprises the steps of: preparing said main frame of said molding strip so as to have a passage at a head portion thereof, while preparing a mold block so as to have a protrusion to form a small flow path by partially narrowing said passage; disposing said main frame in said mold block so as to define a cavity for molding said end cap, said cavity being formed between the head portion of said main frame and said mold block; injecting a molten synth...
