This study was carried out to aim development of new system to recycling waste cans of aluminum. This process is the essentially solid phase technique, frictional heat and pressure caused by relative motion allows a plasticized layer to form without the need for an external heat source such as furnace heat. The principle is characterized that rotating plunge is applied axial load onto the scraped aluminum which is filled in a cartridge with extruding nozzle. The plasticized layer limited thickness and forms in close contact to the r**ating plunger. With continued generation of the plasticized layer formed, scrap canned material is extruded into wire form through the cartridge.Preliminary experiments was performed using fine MIG welding wire or solid block of aluminum as scrap materials which was packed in the cartridge using several parameter combinations. The results shows rotation speed of plunger and frictional pressure give a significant effect of processing time and martial temperature reaches 750K in processing. It is considered that lower processing temperature resulted in reduction of pollution gases such as dioxin and reducing of processing time comparing with conventional fusion process.This project was successfully carried out to proof the principal of novel approach for waste materials processing, however the result itself was limited. The main reason is the reduction of project budge. The process will be expand into continuously processing from batch system which was developed in this project.
