The Numerical and Experimental Study on the Compression and Transfer Molding of Rubber Materials.

In this paper, a numerical study of compression and transfer molding of rubber materials will be presented. A three dimensional analysis is used for the numerical study. The program developed can predict the flow pattern, temperature, degree of cure, stresses within a part and press force change during filling and post-filling. Of particular interest is the change of stresses within a part and press force during post-filling due to thermal expansion of a material and the degree of cure. PVT, viscosity and curing kinetics data of one the rubber material are used for the calculation of pressure during filling and post-filling. [ABSTRACT FROM AUTHOR]
