Abstract: A first sealing member and a second sealing member are disposed respectively on a lower mold and an upper mold. During a process of closing the lower mold and the upper mold, a gap between the molds is sealed by the first sealing member, thereby forming an enclosed space between the molds. Thereafter, a gas in the enclosed space is discharged. As the closing process progresses, the enclosed space is divided by the second sealing member into a sealed room and a production cavity, followed by a liquid resin being supplied to the production cavity.

Abstract: A method for predicting the resistance to heat deterioration of a sulfur-vulcanized isoprene rubber is disclosed. The nuclear magnetic resonance spectrum of the isoprene rubber is obtained by the use of a solid state nuclear magnetic resonance method employing magic angle spinning. The spectrum of a cross-linked structure ? and the spectrum of a cross-linked structure ? in the nuclear magnetic resonance spectrum are identified. The percentage of the cross-linked structure ? and the percentage of the cross-linked structure ? in the overall cross-linked structures of the sulfur are computed from the spectrum. From the computed percentages, the resistance to heat deterioration of the isoprene rubber is predicted.
