Abstract

The research aims to analyze the effect of metering stroke on product quality. Metering strokes relate to product weight and mold capacity. The material used is Polyamide (Nylon) 66, using an ENGEL 50ton capacity Injection Molding machine.  The research method used is an experimental method before mass pre-production with stroke metering variation as a production parameter. A normality test was used to investigate the experimental data. Shapiro-Wilk's formula on Minitab® software was used to process the data. Product defects caused by an improper metering stroke often in the injection process are short mold and flashing prints. The results show that short mold production defects occur when the metering stroke is 60 mm due to the material does not fill the full cavity. Furthermore, flashing occurs when the metering stroke is 70 mm due to out of cavity capacity. Therefore, the appropriate parameter is a 65 mm metering stroke with good quality part results.

Abstract

This study aims to determine the direction of development in the world of Mold & Dies design in the world. Data searches were carried out through science direct databases using the design of molds and dies as keywords with a limitation of open access journals between 2015 - 2020. The results were comprehensively analyzed based on year, publisher's name, institution, and the country as well as research subjects. Files from Mendeley software are saved in Reference Manager Format (.RIS) format which is processed into VOSviewer software to find out the bibliometric map. The results revealed that the highest number of publications is in a procedia manufacturing journal. The most contributing country in the European continent indexed in Scopus is Germany. Within the output in the form of network visualization, it is found that several novelty potentials are in line with the direction of the development of the study with the parameters of the number of population and the year of the research output. Publications on the most similarity and chance of novelty on research topics are in Cluster 1, which consists of Energy Efficiency, Decision Process, Plastic Materials, and Sustainability.Keywords: Novelty, Injection Mold Design, Bibliometric Maping, VOSviewer
