This paper presents the original development of an experimental approach in studying the multiple tensile characterizations as key quality characteristics for several different plastic gear materials related to various parameters in injection moulding process. In this study, emphases are given on a new low-cost mechanism for the testing of the injection moulded plastic spur gear specimens with various teeth module. The testing fixture are developed and validated to provide uniform state of tension with series of plastic gear specimens produced in accordance with the systematically designed of experiment. The effects of changes in the process parameters including melt temperature, packing pressure, packing time and cooling time at three different levels on the elongation at break and ultimate strength of plastic gear is evaluated and studied through the proposed experimental approach.

The high-performance plastics usage is increasing in the automobile field because of its advantages over other metals and alloys. Corrosion resistance, light weight, low cost, flexibility in design are the major advantages of plastics above the conventional metallic materials. In this paper a metal version component converted into plastic version in order to increase efficiency, reduce the overall cost of a two-wheeler and to improve the production rate of component. Different types of material such as PP + 15% TALC, PP + 30% GF, PP + 30% TALC, Nylon 6 + 15% GF, Nylon 66 UF, Nylon 6 UF, Nylon 66 + 30% GF, ASA LI941 and ASA LI913 tested for 10,000km road test, vibration test and fitment test. An injection moulding used to produce the component and ‘Mouldx3D’ software was used for mould flow analysis and other simulation. The different parts of injection moulding tool made up of C45, P20 and D2 materials. Among different materials, ASA LI913 was selected since it has better weather resistance than others and the impact strength matched to metal version component. Finally, it was found that the cost of the component made of Plastic considerably less than same component made of metal.

This paper deals with fabrication and characterization of unique polyphenylene ether/polystyrene/nylon-6/glass composites. Compounding of ternary blends with glass fibres was performed using twin screw co-rotating extruder. Test specimens were fabricated by compression moulding and injection moulding. Effect of maleic anhydride, fibre type (chopped and long), fibre content (30 wt. % and 40 wt. %) and fabrication method (compression moulding and injection moulding) on mechanical and thermal properties was studied. Maleic anhydride negatively influenced mechanical and thermal properties. Composites with 40 wt. % chopped fibres showed superior mechanical strength and those with 30 wt. % long fibres showed superior thermal properties, tensile and flexural moduli. Injection moulded specimens exhibited superior mechanical and thermal properties. The composites were studied for moisture content, density, melt flow index, glass transition temperature, thermal degradation temperature and mechanical properties. Interfacial strength was examined using scanning electron microscopy.

Injection moulding process is one of the common processes to produce plastic parts from simple to complicated parts. This paper focuses on the injection process analysis of a 25 tooth spur gear. Three runner system are proposed for the gear and each system will be analysed using Autodesk Simulation Moldflow Advisor. The most suitable design will then be chosen based on the results obtained from the simulation. The design undergoes cooling quality, sink mark, fill + pack, and warp analysis. Based on these analyses, Design 1 gave the better results compared to Design 2 and 3. From there, Design 1 runner system is chosen for the injection moulding mould which will be fabricated later in the research.

Staining techniques can be used for either the identification of different polymers or for the differentiation of specific morphological domains within a given polymer. To reveal morphological features in nylon 6, we choose a technique based upon diffusion of the staining agent into accessible regions of the polymer.When a crystallizable polymer - such as nylon 6 - is cooled from the melt, lamellae form by chainfolding of the crystallizing long chain macromolecules. The regions between adjacent lamellae represent the less ordered amorphous domains into which stain can diffuse. In this process the lamellae will be “outlined” by the dense stain, giving rise to contrast comparable to that obtained by “negative” staining techniques.If the cooling of the polymer melt proceeds relatively slowly - as in molding operations - the lamellae are usually arranged in a radial manner. This morphology is referred to as spherulitic.

ABSTRACTPhysical properties and structural parameters have been measured for ropes of nylon 6 as a function of the number of use operations. The fractional content of the α crystal form, sound velocity, birefringence, tensile strength and length all increase systematically and significantly with increasing the number of use operations. The fractional content of the γ crystal form and fiber diameter decrease with use. These trends indicate that the measurement of such properties and structural parameters, especially the length, provide a possible basis for establishing a reliable, rapid, and convenient nondestructive characterization method to predict the remaining service life of nylon 6 ropes.
