This unit is a 200-ton capacity Williams-White Moline machine equipped with three 24" x 24" cored steam platens and pull-back pistons for rapid pressure release. At the laboratory, the hydraulic press was used to cure, i.e. toughen or harden, molded rubber articles. This photograph was included in a 1949 Naval Air Experimental Station report on compounding rubber.
