Opis:
The parameters of the injection moulding process have a significant influence on the properties of the moulded parts. Selection of appropriate injection conditions (e. g. the injection temperature, mould temperature, injection and holding pressure, injection speed) contributes to the productivity and energy consumption of the injection moulding process as well as to the quality of the moulded parts. The aim of this study was to evaluate the influence of injection moulding parameters on properties of poly(ethylene) mouldings. Regranulate obtained from recycled film, which is a mixture of low-density poly(ethylene) and linear low-density poly(ethylene), was used for testing. Samples in the form of standardised tensile bars of type A1 were produced by injection moulding. A Krauss-Maffei KM65-160C4 injection moulding machine was used for this purpose. Variable parameters of the this process used in the study were: injection speed, mould temperature and holding pressure. The results of tensile strength tests of the obtained samples are presented. The weight and dimensions of mouldings from four different regranulates were also investigated. The effect of injection moulding conditions on the properties of poly(ethylene) mouldings was shown in the investigations. The mass of poly(ethylene) mouldings is dependent on the holding pressure.

Opis:
The increasing needs of using aluminum epoxy composite as a replacement to solid metal rapid prototyping has opened to interests in optimizing its machining processes. This paper reported on the success of optimizing the surface roughness of aluminium epoxy composite using milling process along with a new finding on the best combination parameters. Taguchi method was used as the optimization method whereas spindle speed, feed rate, and depth of cut were set as input factors using an L9 Orthogonal Array. Analysis of Variance was used to identify the significant factors influencing the surface roughness. Experiment was conducted in dry condition using a vertical milling machine and the surface roughness after the machining was evaluated. Optimum combination of cutting parameters was identified after the finest surface roughness (response) based on the signal-to-noise ratio calculated. Cutting parameters selected after preliminary testing are cutting speeds of (2000, 3000 and 4000) rpm, feed rate (300, 400 and 500) mm/min, and cutting depth (0.15, 0.20, and 0.25) mm. The result showed that cutting speed had the largest percentage contribution to surface roughness with 69% and the second highest contribution was feed rate with 22% and depth of cut at 9%. The spindle speed was found as the most significant factor influencing the quality of surface roughness. The result is significant particularly in providing important guidelines for industries in selecting the right combination of parameters as well as to be cautious with the most significant factor affecting the milling process of metal epoxy composite.
