oa Injection Moulding Fumes Purified

Catalytic combustion is now a well established method of controlling a wide range of air pollution problems. A relatively new and improved process for the production of plastic injection mouldings resulted in the discharge to the working environment of small, but potentially offensive, volumes of malodorous or toxic fumes. This article very briefly describes the new process, then shows how existing well tried technology has been adapted to solve the pollution problem economically.
