Abstract

One of the processes commonly used in making plastic goods is the injection molding process. Every process in injection molding has a very important role. A less-than-perfect process will result in defects or failure in the product. To reduce product defects, one of the processes that must be researched is the barrel purging process. The purging volume on the mini injection machine using the V-line method is inconsistent, as evidenced by the fact that if the purging waste, or what is usually called an avalanche is weighed, it will produce a non-uniform mass. This research uses a mini injection machine with the V-line method which has 2 main steps to carry out the plastic injection process; dosing and injecting. Unlike injection engines in general, this engine does not have a check-ring to withstand back pressure. This machine uses a shut-off system as a replacement for the check-ring role. This machine has never been subjected to a purging volume consistency testing process. The consistency of the purging volume greatly influences the product uniformity results. The research method used in this final assignment is direct. Data collection and test specimen collection will be taken directly on the mini injection machine using the V-line method. The steps taken in this research are planning, taking data, taking test specimens, processing test specimen data, and comparing test specimen data to obtain analysis results. The research results show that the mini V-line injection machine cannot support mass production, because increasing the screw rotation speed will affect the consistency of the volume of plastic that will be produced in the barrel, causing production to not run quickly and precisely.

Abstract

Plastic material testing is conducted to determine the mechanical properties and strength characteristics of plastic materials. The selection of appropriate plastic material is a critical aspect in product design to ensure optimal strength and quality. At PT XYZ, a discrepancy was identified between the elastic modulus values stated in the material datasheet and those observed in the actual product material. Such differences can affect the fracture limit, resulting in products that do not meet design specifications. In response to this issue, a product bending test machine was proposed and designed. The VDI 2222 methodology was utilized in the design process, and testing was performed using PMMA specimens in accordance with ASTM D790 standards. Verification was conducted using the Zwick Roell Z020 Universal Testing Machine, accompanied by analytical calculations to determine the accuracy of the newly designed machine. The study resulted in alternative design options for the bending test machine based on the requirements list and calculated accuracy levels. The accuracy results showed a force accuracy of 98.63%, displacement accuracy of 58.67%, and stress accuracy of 97.34%. The significant deviation in displacement is suspected to be due to system incompatibility and additional jig components that were not perfectly perpendicular to the pressing plane, leading to measurement errors. The current prototype of the product bending test machine is considered not yet suitable for industrial applications. Further review is required, particularly in calibrating the displacement between the mechanical components and the electronic control system.
