Abstract:
A method of molding an elastomeric article comprisingputting an elastomeric article in a mold, softening the elastomeric article in the mold by heating the elastomeric article, pressing the elastomeric article against the mold by pressurizing an inside of the elastomeric article by introducing a fluid therein, and changing the pressure of said fluid in a short cycle so as to beat the elastomeric article against the mold, wherein said fluid is a heating medium which is introduced into the inside of the elastomeric article to heat the elastomeric article, the pressure is changed at least two cycles between a maximum pressure P1U for the process of heating the elastomeric article and a lower pressure P1D less than the maximum pressure P1U but not less than Â½ times the maximum pressure P1U, and one cycle of the change in the pressure comprises a decrease of short duration of not more than 10 seconds and an increase of short duration of not more than 10 seconds.
