Abstract

A preliminary investigation on plastics joining process by laser on waste plastics (HDPE) with average thickness 1.5mm is carried out. Stack joining is performed on the plastic in order to obtain maximum joining surface area. The plastic is re-used in order to minimize rate of solid waste also to maintain the material’s properties since re-processing will just decrease it. Furthermore, indirect contact between laser beam and material has resulting little to no reaction forces imparted upon the material in the same time eliminate tool wear, material damage and machine vibration. Process parameters that have been chosen in this study is based on OFAT experiment which are laser power, travel speed and gas pressure. Full factorial method of parameter design is used as design of experiment (D.O.E) technique to obtain optimal process parameters. The experimental is performed by simultaneous process of joining and cutting. The machine used was Helius Hybrid 2513 Laser Cutting Machine. Results show that Laser Cutting machine has successfully joined the plastic. Quality and performance analysis of the join are performed by visual inspection and flexural test. From analysis, it shows that higher level has produced optimum responses.
