Optimization of Nozzle Section in Plastic Injection Moulding Process

Abstract

P lastics was discovered at the end of the 19th century and developed further, especially after the Second World War. They were begun to be used in the industry and in our daily life with its thousands of varieties [1-3]. For plastic part manufacturing determined according to the physical and chemical characteristics of plastic, various manufacturing techniques have been developed (injection, extrusion, blowing, etc.). Almost 33% of plastic parts are manufactured by using injection moulding technique [4,5]. It is widely used in mechanical construction, automotive components, aerospace and aeronautical industries, and household products. Many studies have been made on manufacturing with injection moulding technique that has an extensive manufacturing capacity [6-9]. This technique enables a low cost and efficiency, fast production cadence, and high dimensional accuracy of complex plastic parts. The quality, geometrical structure, dimension tolerance, surface quality and factors affecting strength of the parts manufactured with the Article History:
