Abstract
An apparatus for thermally densifying thermoplastic articles, particularly those of the expendable type. The apparatus includes a chamber for placing the thermoplastic articles within, a heater for heating the thermoplastic articles placed within the chamber to a temperature effective for the thermal densification of the thermoplastic articles, a temperature sensor located proximate to the heater, and a controller for controlling the heater responsive to the temperature sensor, which is capable of providing a temperature within a range from about the temperature effective for thermally densifying thermoplastic articles to a temperature below the point of significant thermal degradation of the thermoplastic articles. A process for the thermal densification of thermoplastic articles are also provided.
