Development of a Precision Casting Process for Acrylic Plastic Spherical Shell Windows Applicable to High-Pressure Service.

Abstract

A casting technique was developed that allows casting of acrylic plastic spherical shell sector windows to curvature and thick- ness tolerances generally found only in machined windows. By means of this technique, 18-inch OD X 10-inch ID windows were made; after a minor polishing operation they met the ASTM-D-702 specification for optical clarity. The mechanical and physical properties of the castings were in the same range as those of commercially available cast plates and sheets. (Author, modified-PL)
