Fabrication of a Thin-Walled Plastic Shell Using Emulsion Technique

Thin-walled plastic hollow shells were fabricated using a conventional emulsion technique. Polystyrene and a copolymer of acrylonitrile and styrene were investigated. Wall thickness of the resultant shells was found to be reduced at low-concentration of plastic and high temperature for the underwater drying process. Preliminary results indicate that shells of approximately 1 mm diameter having a wall thickness of less than 3 μm were easily produced.
