“Design & Fabrication of Plastic Strip Machine”

Abstarct :- This research focuses on the design and fabrication of a plastic strip machine that converts commonly discarded plastic materials into uniform plastic strips for reuse in manufacturing and creative applications. The machine is engineered to melt and extrude plastic waste through a controlled heating and shaping mechanism, using components such as a variable-speed motor, heated barrel, screw conveyor, and precision die. Key design parameters, including barrel temperature range, extrusion speed, strip width control, and cooling system efficiency, were systematically analyzed and optimized. The project emphasizes the use of cost-effective materials and locally available components to ensure the machine's accessibility and affordability for small-scale or community-level recycling units. Detailed CAD modeling and simulations were conducted to validate mechanical performance, followed by fabrication and testing of the prototype. The machine successfully processed plastic types such as PET, HDPE, and PP, producing high-quality, consistent strips suitable for 3D printing filament, weaving plastic fabric, or use in prototyping and educational tools. This study not only contributes to the growing field of plastic recycling technologies but also promotes the concept of a circular economy by transforming waste into valuable resources. The machine offers a scalable solution for local recycling initiatives, educational institutions, and small-scale entrepreneurs seeking to reduce environmental impact through innovative material repurposing.
