Integration of CAD CAM Techniques in the Development of an Injection Mould for Automotive Parts

Processing by injection is the technological process by that the thermoplastics material is injected, under pressure, in the cavity of a mould, where it cools down and solidifies. This process is the most common method for obtaining plastic materials. Injection moulding of thermoplastics has emerged as the premier vehicle for delivering high quality, value added commercial products. Continued global competitiveness has increased standards for product capability and quality while requiring reduced product development time and unit cost. Despite advanced design methods and new process technologies, it is becoming apparent that the injection moulding process is neither flexible nor robust. This paper presents a design process using CAD-CAM software applied to an injection mould for manufacturing a plastic component that is used in the automotive industry. The component was analyzed, measured and subjected to simulations that will certify the quality of the final product.
