Given the fact that plastics are found in an increasing percentage in the automotive industry, with a tendency to expand in the future, it is obvious that all auto parts manufacturers are trying to increase productivity and quality of parts. One of the important parameters influencing productivity and part quality is the cooling time as well as the cooling mode of the part or mould. The paper studies some important aspects of the influence of cooling time on the quality of engineering polymers used in the automotive industry. In the paper, a series of mathematical calculations were carried out to determine the cooling time equation, analysing the conductive heat transfer, in the case of plastic plate, between the cooled walls of the mould. Practical studies are carried out for four types of polymers very important in the automotive industry, the part used for the test having flat surfaces. Deformation magnitudes were determined as a function of cooling time, using the same mould cooling temperature.
