【 摘 要 】

Injection of polymers is one of the most widely used technology in the production of plastic parts. During injection moulding it is important to analyse the individual factors of the injection process so that the optimal injection parameters can be set from these established process conditions. When injecting, it is important to achieve the optimal production process to reach optimal production costs, increasing the quality of the product and eliminating possible defects in the products. The presented work deals with the investigation of the influences of the process parameters of the injection process (holding pressure and mould temperature) on resulting nano-mechanical properties. To measure nano-mechanical properties by the DSI method, a polypropylene sample was chosen. Measurements were performed on the Nano-Combi-Tester. From the results of this study it is clear that optimal nano-mechanical properties are required to optimize the process parameters of the whole injection moulding process.
