“…Some defects that appear when setting the highest injection temperature are flashing, bubbles, warpage, and splay. The emergence of flashing defects is caused by the low viscosity of the material due to the influence of the injection temperature used above the melting point of the specification of the material used, so that the plastic melt will easily pass through the mold gap, this statement is in accordance with research conducted [5]. Meanwhile, warpage defects also arise due to the high injection temperature setting.…”

“…Not only that, bubble defects appear when the injection temperature parameter is above the recommended burst point for plastic materials [10]. Meanwhile, if the injection temperature is at a temperature of 225 °C, it will cause flashing defects because the molten material has a low viscosity so that it easily flows through the mold gap [5].…”

“…Several studies have been conducted to see the effect of setting parameters, that as the injection temperature increases, the potential for flashing defects to appear is getting bigger [5]. Meanwhile, as the injection pressure increases, the injected material becomes denser, but the potential for defects also appears, namely flashing [6].…”

When performing the injection molding process, the influence of the set parameters such as injection time, injection pressure, and other parameters used will affect the mold result. The problem that arises when doing injection molding using multi-cavity molds is the appearance of product defects. The purpose of this study focuses on finding the parameters of the injection temperature, injection pressure, injection time and optimal interactions, and the position of the cavity orientation so that the product produced from multi-cavity molds is minimally flawed. The method used is to conduct experiments on the plastic molding process and compare the results of the different cavity positions in the vertical and horizontal positions. Experimental design chosen is DOE Factorial. The results obtained that there is an influence of injection temperature, injection pressure, injection time and cavity position on the number of defects. The recommended cavity position is to adjust the horizontal position right -left, because it produces minimal product defects. The smallest chance of defects occurs when the interaction of injection temperature is 210 C, injection pressure is 42 Bar, and injection time is 4.5 seconds.

STAIN Kudus librarian's has an important role for the success of user education activity of new students at UPT Library STAIN Kudus. The user education activity in the STAIN Kudus library as a training and education activity for library users, teaches users about how to use services and searches in libraries, as well as teach users how to be polite users, good personalities, obedient to the rules in the library, not plagiarism of scientific work, and mutual respect with the elements of library managers. Education, in this case user education in STAIN Kudus libraries plays a dual role as a form of transfer of knowledge and transfer of value from librarians / managers to library users

“…The material for motorcycle plastic bodies is called Acrylonitrile Butadiene Styrene (ABS) plastic, a type of copolymer composed of several forming monomers that are heat stable, chemical resistant, and have high strength (Wibowo et al, 2023). This research only discusses the manufacture of motorcycle plastic bodies in partial processes, meaning that there are special requests from some customers, especially customers from abroad (Mawardi, Jannifar and Lubis, 2019;Kale, Darade and Sahu, 2021). In the partial process with production requests every year for the production of plastic motorcycle bodies, there is a special demand for export production in certain quantities and types, which has an impact on part stocks becoming unbalanced (Sundararajan and Terkar, 2022).…”

Purpose: This study aims to analyse the causes of partial set-up work that is not optimal and provide solutions to the sub-optimal set-up work on family-type moulds in type A. Methodology/Approach: This study uses an 8-Step improvement approach combined with several methods, including Focus Group Discussion (FGD), Quality Cost Delivery Safety Moral (QCDSM), and Specific Measurable Achievable Relevant Timebase (SMART) method. Findings: This study found the cause of the partial set-up work being less than optimal due to problems with the Man, Method, and Machine factors. The results of this study show that the set-up time decreased from 240 minutes to 73.4 minutes or 68%. Meanwhile, the process cost for the partial set-up itself decreased from $75 to $3 or decreased by 97%. Research Limitation/implication: This research has limitations in the partial set-up process, which is less than optimal in plastic injection family-type moulds in the Motorcycle Industry. Originality/Value of paper: This research has value in optimising the production of plastic injection family-type moulds by reducing set-up time and operational costs for making spare parts in the Motorcycle Industry
