METHOD FOR MANUFACTURING SOLID MOLDED ARTICLE AND SOLID MOLDED ARTICLE

Document Type and Number:

Japanese Patent JP2004114514

Kind Code:

A

Abstract:

To inexpensively manufacture a duct of trial production with a smooth inner face in a short period of time.

A flexible belt-like hydraulic raw material 11 is wound around an inner mold 10. This hydraulic raw material 11 is composed of a glass fiber base fabric with a hydraulic resin. The hydraulic raw material 11 wound on the inner mold 10 is dipped in water mixed with a sealing compound. After the hydraulic raw material 11 is cured, this cylindrical hydraulic raw material 11 is divided into two parts, and the inner mold 10 is taken out. Then, the two parts are stuck to the original shape to complete the duct of trial production. A smooth face part is formed with the sealing compound on the inner peripheral face of the duct of trial production.
