であるが熱可塑性樹脂に比ベサイクルタイムは短かい。The third step of the present invention is a step of cooling the heated Tsujiko molded body while pressurizing it in a metal plate. The temperature of the mold in this step is below the softening temperature of the resin. The lower the mold temperature, the faster the resin will cool and solidify, which will shorten the molding time, but for crystalline resins, it is important to increase the degree of crystallinity and avoid rapid cooling. The optimum temperature is selected accordingly. The cooling time depends on the type of resin,
The cycle time is usually about 30 seconds to 5 minutes, although it varies depending on the temperature of the mold, but the cycle time is shorter than that of thermoplastic resins.

This metal core was rotated at a speed of 50 revolutions per minute while being heated with an infrared lamp, and the roving was then wound at a winding angle of ±45° until the thickness was approximately 2°. The obtained hole-shaped molded product was placed in a heating furnace together with the core metal, and heated to 280
After heating at .degree. C. for 10 minutes, the mixture was taken out of the heating furnace and put into a mold at 50.degree. C. and cooled under pressure. After 2 minutes, the mold was removed and the core metal was pulled out, yielding a pipe with a smooth surface.
