摘要： PURPOSE: To extrusion mold liquid crystal resin composite material having a thick diameter without necessity of separately providing a combining unit at the downstream side of an extrusion die by imparting the orientation effect in the die. CONSTITUTION: A method for extrusion molding a liquid crystal resin composite material comprises the steps of extrusion molding material resin obtained by mixing thermoplastic matrix resin and thermoplastic liquid crystal resin at a mixing ratio capable of compounding the liquid crystal resin in fibrous state in the matrix resin at the temperature of the range from the lowest moldable temperature of the matrix resin to the liquid crystal transition temperature or higher of the liquid crystal resin The material resin is fluidized toward the downstream side in an extrusion die having a die hole reduced in its crosssectional area as the resin is transferred from the upstream side to the downstream side, thereby extrusion molding the composite material while orienting in the die. A plurality of the holes 11-14 are provided in the die 3, the composite materials extruded from the holes are combined in the die to be integrally fusion bonded to each other.

摘要： PURPOSE:To improve the surface smoothness of a molding by maintaining a die tightening pressure at a lower level than a foaming pressure for a specified period when the reaction injection molding process of polyether and isocyanate is performed. CONSTITUTION:A polyurethane molding is manufactured using a reaction injection molding technique with a liquid A containing highly active polyether and a liquid B containing isocyanate. In this case, a die tightening pressure is maintained at a lower level than a foaming pressure during a period until the die is opened after the rise of the foaming pressure when a reaction curing process is underway following injection of the liquids into a molding die. Thus it is possible to eliminate a residual stress near the surface of a molding when a curing process is completed and subsequently, improve the surface smoothness of the molding.
