Abstract: A method wherein an article is molded of a heat-fusing material or plastisol, either liquid or dry, in a mold having an array of gas impingement jets disposed adjacent the backside of a mold surface for controlling the temperature over respective first and second areas of the mold surface. There is included first and second gas heating and cooling circuits each including a blower and dampers for supplying gas at the gas impingement jets associated with the mold. All of the gas impingement jets are supplied with heated gas to preheat the mold surface to a non-gelling temperature and a liquid plastisol coating is applied to the mold surface. To obtain the coating, the mold is filled and the excess plastisol is removed from the mold by dumping the plastisol from the mold into a dump tank.

Abstract: A liquid-gas deaeration assembly having a plurality of downward slopping cone shaped dispersion members stacked on top of each other and in spaced relationship to each other. Each dispersion member has a circumferential edge extending beyond the edge of the next lower member. The dispersion members have damming means disposed above the upper surface and spaced from the edge to spread the liquid over the surface.
