摘要： A process for injecting a urethane material into a mold cavity from a gate to mold articles. Urethane molded articles are produced by first forming a coating film layer on the inside surface of a mold cavity. Next, a first urethane material containing pigment is injected into the cavity. Finally, a second urethane material containing more pigment than the first urethane material is injected into the cavity.

摘要： A small amount of a non-yellowing surface-forming polyurethane material containing a polyether polyol, a hexamethylene diisocyanate trimer, a coloring agent and an organic bismuth catalyst is initially injected into a mold cavity under reduced pressure to form e.g. the surface portion of a polyurethane covering for a steering wheel. An inner-forming polyurethane material is subsequently injected into the cavity under reduced pressure to form an inner portion of the covering.

摘要： A first injection mechanism of an apparatus for molding articles injects coating material into a cavity defined in a clamped mold, thereby forming a predetermined coating on the inner surface of the cavity. After the coating material is injected into the cavity, a decompression mechanism lowers the pressure in the cavity through at least one vent. After the coating is formed on the inner surface of the cavity, a second injection mechanism injects molding material into the cavity. When the pressure in the cavity is being lowered, an opening-closing mechanism opens the vent. Before or during the injection of the molding material, the opening-closing mechanism closes the vent.

摘要： A polyurethane material is injected into a mold cavity having a reduced pressure to form e.g. the surface portion of a polyurethane covering for a steering wheel. A polyurethane material for forming a substantial inner portion thereof and free of any coloring matter is, then, injected into the cavity. Then, a polyurethane material containing coloring matter is injected into the cavity to form the remaining inner portion of the covering.

摘要： In a first valve mechanism 30, a positive pressure spring 31 presses a first valve plug 34 to seat an external ring projection 37 of the first valve plug 34 onto a bottom surface 39 of a support cylinder 35. The first valve mechanism 30 opens at a first valve-opening pressure P1 responsive to a pressure balance across the positive pressure regulating valve plug 34. In a safety valve mechanism 60, the same spring (the positive pressure spring 31) presses a safety valve plug 61 via the external ring projection 37 seated on the bottom surface 39 to seat a sealing ring projection 62 of the safety valve plug 61 onto an upper face 63 of a partition wall 28. The safety valve mechanism 60 opens at a second valve-opening pressure P2 responsive to a pressure balance across the safety valve plug 61. A pressure receiving area S1 of the positive pressure regulating valve plug 34 and a pressure receiving area S2 of the safety valve plug 61 are determined to open the positive pressure regulating valve mechanism 30 but maintain the safety valve mechanism 60 in its closing state when an internal pressure of a fuel tank reaches the first valve-opening pressure P1.
