METHOD FOR INJECTION MOLDING OF THERMOPLASTIC RESINS |
摘要 |
An economical method for facilitating injection molding of a thermoplastic resin by reducing the viscosity of a molten resin without impairing the physical properties of the resin, the surface appearance of the molded article and productivity. In the method for injection molding of a thermoplastic resin, a thermoplastic resin in which not less than 0.2% by weight of carbon dioxide is dissolved is injected into a mold cavity pressurized with a gas beforehand to at least a pressure where foaming does not take place in the flow front of the molten resin. <IMAGE> |
