Abstract
Present invention is related to an extrusion equipment for processing a fibre composite. The extrusion equipment comprises a decompression and a melt tank arranged and operated vertically along with the direction of gravity. The melt tank comprises a melt tank impregnation section and a melt tank control section with a melt tank cavity as a channel condition defined within. The channel has its inner diameter or passage gradually decreased from top to bottom. The extrusion equipment provided by the present invention is configured in the direction of gravity for processing the melted thermoplastic resin and the fibre vertically for avoiding fibre fracture or breakage and improving the quality of the final products. As the melted plastic is processed vertically along with the gravity, the melted plastic could transfer or pass through the channel quickly without resulting decomposition due to the high heat and the long retention time in the cavity.
