Development of extrusion machine design for recycling plastic waste.

Indonesia as the second biggest country with plastic waste encounter serious problems in treating plastic waste. Lack of effective system in treating and recycling plastic waste make this problem more severe. Many efforts have been conducted to solve this problem. One of the solutions is to recycle the plastic waste. This paper discusses the development of an extrusion plastic machine design along with its material selections and cost, and static analysis. The proposed design is established in which the machine frame meets the ergonomics requirements and space optimization. It is also considered that all components and materials to build the machine are available in the market and can be adjusted with the existing conditions. The safety factor for the frame is obtained to be 84, implies that the proposed design has adequate strength. Moreover, by comparing to the extrusion machine available in the marketplace, the proposed extrusion machine can obtain the cost of about IDR 8,703,545. [ABSTRACT FROM AUTHOR]
