Abstract

The increasing volume of plastic waste demands sustainable management efforts, one of which is recycling it into useful products. A small-scale vertical injection molding machine can be a solution because it can melt plastic waste and mold it into simple products. This study aims to design a vertical injection molding machine that processes plastic waste into useful recycled products. The design used the VDI 2222 method, which covers establishing the requirements list, functional analysis, generating alternative functions, forming concept variants, and evaluating the variants based on technical and economic aspects. The machine was designed with an injection capacity of 210 cc, a maximum temperature of 350°C, and for PP, LDPE, and HDPE plastics. Of the two concept variants developed, variant 2 was selected, with technical and economic scores of 75% each, while variant 1 scored 50% and 58%. The selected variant consists of a lower control panel, a hollow-steel frame, a hollow-steel and plate mount, a conical hopper, a hot runner heater, and a pneumatic press. These results provide a basis for the detailed design and fabrication stages of the machine.
