Abstract: Nanoparticle is hard to produce because the process is difficult, and the material amount is always insufficient. In conjunction, a high amount of cost will be used to produce nanoparticle. In addition, the current material to produce nanoparticle are expensive, hard to obtain and depleting. Hence, research is followed by extraction of the nanoparticle. Then, the samples were measured and characterize the Al2O3 nanoparticle. Currently, the size of Al2O3 nanoparticle obtained is 800nm. Hence, the experiment will be proceeded in order to achieve Al2O3 nanoparticle size from 1nm to 100nm. The aluminium nanoparticle should be improved in all aspects compare to the current material nanoparticle. Aluminium oxide (Al2O3) was introduced to solve the problem exist with the current nanoparticle. In this paper, research was conducted for the manufacturer to provide a large amount of fine Al2O3 nanoparticle hence cost saving. Electric Discharge Machine (EDM) was used to produce the nanoparticle. Several stages will be drafted put in this paper in order to achieve the objectives. The stages involved was developed a new chamber for Al2O3. The next stage is to use this device and synthesis of the nanoparticle. This
A seal manufacture factory located in Ipoh, Perak produces two types of seal available in the factory which are metal and plastic seals. Due to manual assembly, human operator tends to get fatigue for doing repetitive task in one long shift. When this occurs, minor error such as misplace or wrong orientation of jaw will occur. Moreover the jaw sometimes can be missing during transportation of work – in – progress to another process. The objective is to design a jig that have the ability to detect reverse and missing jaw so that the finish product which has the quality problem will be prevented from being shipped to customers. The jig must also have a flexibility to be used for other plastic seal product. For methodology, each and every stage was explained in detail. In result and discussion section, House of Quality (HOQ) was used to determine the highest criteria weightage. The important criteria which will be carried forward to Analytical Hierarchy Process (AHP) are 15.9% on flexibility and ease of maintenance, 15.4% on both ease of use and longevity of jig usage, lastly 15.2% for accuracy checking. The result obtain after AHP computation are Design 1 with 20.7%, Design 2 with 13.7%, Design 3 with 22%, Design 4 with 27.1% and Design 5 with 16.5%. Design 4 is selected due to the highest weightage after computation. Final selected design was justified according to characteristic needed in objective.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
