Abstract
A process and apparatus is provided for explosively forming plastic objects from shredded plastic such as recycled plastic having different compositions. The shredded plastic and an explosive gas mixture is introduced into a mold cavity having the shape of the object to be formed, and the gas mixture is ignited, generating sufficient heat and pressure to force the plastic to conform to the shape of the mold cavity. The temperature and pressure in the mold cavity is controlled during the explosion by releasing combustion gases from the mold cavity.
