Thermoforming (Vacuum forming) originally found most of its applications in the packaging industry. Recently this method is being used increasingly in the automotive and computer industries. In this paper we discuss the effects of forming conditions on the thickness distribution in products made with modified PVC which is often used for computer housings. The forming conditions studied are heating temperature, mold temperature, vacuum speed and sheet direction (anisotropy of sheet). A three step forming process is adopted; blowing process, stretching process and vacuuming process. The effects of heating temperature, mold temperature, and vacuum speed on thickness distribution are small. On the other hand anisotropy of sheet is the biggest factor.
