Abstract

Injection molding is one method that is widely used because of the lower cost required. The resulting plastic product is inseparable from the problem of product defects. This research uses quantitative methods and data collection or field on the subject of research, after that analyzing each parameter. The results of this study the occurrence of several defects in the product, namely short molding product defects have the most defects, namely 3, while over mold, sink mark and weldmark or flow product defects are 2 and the least is the hole product defect, namely 1. The setting at temperature determines the quality, especially in terms of appearance, at a temperature of 190 0C gives a much better product quality compared to temperatures of 180 and 200 0C. Analyze the optimal screw speed of 8 Rpm so that the resulting product can become a desired bottle product. Analysis of product defects that occur are Sink Mark, Weldmark or flow mark, Shrinkage and Over Mold which occurs at temperatures of 180 - 200 0C. The defects that most often arise because the mold has uneven lines so that defects occur in bottle products.

Abstract

This research aims to test and validate the performance of the IMBP Machine that has been created, ensuring that the machine can operate effectively and perform its components' functions as expected. Additionally, the objectives of this study include achieving the desired processing results of 50 grams per hour of plastic seeds and systematically developing the process of manufacturing the IMBP Machine, starting from the construction of the iron frame, gear housing, end plate, barrel, hopper, cover, packing, knife shaft, blades, binding shaft, and finishing process. The research methodology employed encompasses field observation, literature review, testing and measurement methods, as well as analytical methods. Field observation is utilized to observe and gather data from machines operating in the field. Literature review is conducted to obtain information related to the theory and practices of the IMBP Machine. Testing and measurement methods are employed to evaluate machine performance and collect data regarding the achieved processing outcomes. Furthermore, the analytical method is used to compare the obtained data with the desired specifications, thus validating whether the machine has achieved the intended targets. The research findings demonstrate that this machine successfully produces the IMBP Machine according to the desired specifications. It is proven to function effectively in processing plastic and carbon materials. With the results of this research, it is expected that this machine can contribute positively to plastic waste processing and carbon waste reduction processes.

Abstract

At present, the need to use plastics and the advancement of manufacturing technology for the material itself drive people's demand for plastics, and the development of technology has further increased competition in all fields of industry. Therefore, the plastics industry needs to increase production in terms of quality and quantity. In this way, plastic can slowly replace iron and steel due to its good moldability and light weight. In this research, as a research method, we use quantitative methods by conducting surveys, data collection and field research related to the research theme. After the data is collected, the next step is the fabrication of the test equipment. From the mold fabrication results, the mold is in the shape of a 30 ml bottle with dimensions of 105 mm x 40 mm, inlet ø 6 mm, outlet 3 mm, and the mold is made of aluminum. This mold is called the 3 plate system and the mold consists of 3 main parts which are divided into 3 parts. Good and ideal molding results were obtained with HDPE (High Density Polyethylene) material with injection speed parameters of 8 rpm and temperature of 190°C.
