Experimental Research on Thermoplastic Forming of Spherical Vessel

Abstract:

It is a dieless forming technology to shape spherical vessels with thermoplastic forming. It involves heating a closed shell to the thermoplastic state, and then forming the spherical shape of a container by using gas to exert pressure. This paper researched thermoplastic forming of spherical vessels by attempting to form a soccer-ball shaped closed shell with a roundness error less than 0.15% using a heating temperature of 850°C and a pressure of 0.6MPa . The experiment showed that thermoplastic forming of spherical vessel is feasible.
