Study on the Influence of Processing Condition on Impact Property of Injection-Molded Polycarbonate

Article Preview

Abstract:

The impact property of injection-molded plastic components is an important factor to judge their quality. The aim of this paper is to study the effects of processing conition on impact property of injection-molded polycarbonate (PC). By changing the processing conitions such as injection molding parameters and thermal treatment, different impact samples were acquired. Then, Izod and Charpy notch impact tests were carried out to research the relation between the impact strength and the prcessing conditions. The results imply that different processing conitions will lead to different changes of impact property.
