Volume XXIII (XIII), 2014/2

This paper studies the theoretical and practical issues regarding the manufacture of plastic products precision. We present a study about the influence of moulds temperature on the quality of injected plastic parts than used in the industry. It presents briefly the phenomenon that occur in the injection process and also determine a set of equations on thermal phenomenon that occur during the injection in the mould. Next we present two constructive solutions that contribute significantly to the homogenization temperature of semimoulds injected with one or more nests which increase the quality of parts. In the second part of the paper presents a case study on the size of strains according to the water used in teperature input of circuit cooling. To obtain more efficient results we use five tipes of polymers that are widely used both in automotive and in the home appliance field.
