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

Abstract

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.

Evaluation of specific process parameters and ultrasonically activated injection affecting the quality of filling in thin walled plastic parts

“…With high productivity, it is based on accurate replication of the nest. In the industrial design and manufacturing, it is always a challenge to make a proper compromise between the most desirable shape of parts, tooling cost, their weight and as well as strength and rigidity (Adam et al, 2013). The primary concern is to respect the quality requirements for the moulded parts.…”

Ultrasonic Activated Injection Used on Manufacturing Thin Wall Plastic Parts

“…Because of injection parameters and parts design, plastic parts obtained by injection moulding, can suffer defects such as air bubbles, plastic burns, cracks, plastic peeling and weld lines. This kind of defects may lead to loss of structural integrity or can spoil the part aesthetics [4].…”

“…However, the sets of factorial experiments 2 4 in which the nozzle and the die are ultrasonic activated designate U.S. as a third factor of influence after the contribution that it has to increase the flow path.…”
