Summary: The The study focused on the efficiency, functionality, and operational parameters of a portable plastic extrusion machine intended for creating souvenirs. The prototype was built to provide an efficient, functional, and compact solution for small-scale plastic manufacturing. Its performance was evaluated through trials conducted at varying temperatures and rotational speeds (RPM), with a focus on extrusion output, preheating efficiency, and mold performance. During testing, the machine's barrel was preheated to 240°C for an average of 26 minutes, with the shortest duration spent in an air-conditioned setting. The extrusion process was tested at 163.5, 174, and 195 RPM. The 174 RPM speed produced the most consistent and reliable results, with extrusion times of 17, 35, and 45 seconds. The other settings showed variability and occasional failures in extrusion quality, indicating the need for further process improvements. Mold preheating to 220°C took about 5 minutes, but despite the appropriate heating times, no successful souvenir manufacture was possible due to poor mold design and runner dimensions. Despite these limits, the machine achieved promising results in terms of heating efficiency and extrusion control. To address manufacturing concerns, the report recommends rebuilding the mold to optimize internal shape and runner flow paths. Furthermore, thirty (30) Mechanical Technology students assessed the prototype for utility, ease of use, and performance. The machine received a positive feedback validates the machine's promise for educational, prototype, and small-scale manufacturing applications, with further improvements.
