METHOD AND DEVICE FOR MANUFACTURING PIPE MEMBER

Document Type and Number:

WIPO Patent Application WO/2004/035287

Kind Code:

A1

Abstract:

A method and a device for manufacturing a multi−layer pipe member by a centrifugal molding method capable of hardening layers in a short time, increasing the degree of hardness of an inner surface protective layer, and eliminating the need of after−curing after mold release, the method comprising the steps of inputting molding material containing curing resin or curing resin and inorganic filler, and&sol or fiber reinforced material into a rotating centrifugal molding die for pipe member and radiating light for curing with a centrifugal force applied thereto&semi the device for manufacturing the pipe member, i.e., a centrifugal molding device used for the method comprising a mechanism for feeding the components of molded material and a mechanism for radiating the light.
