Abstract :Polyethylene terephthalate insert ignore into journalissuearticles values(PET); bottles which are thermoplastic materials are used very commonly for the storage and transport of carbonated beverages. The most used production method for PET bottles is the Injection Stretch Blow Molding insert ignore into journalissuearticles values(ISBM); process. There is a variety of parameters affecting the produced PET bottles’ performances. Amongst these parameters, stretch rod movement, blowing pressure and preform surface temperature are the most important ones. Assignation of the optimal design parameters in PET bottles is taken into account. The effects of the parameters such as Preform Temperature insert ignore into journalissuearticles values(°C);, Stretch Rod Position insert ignore into journalissuearticles values(mm); and Final Pressure insert ignore into journalissuearticles values(Bar); were analysed with the Taguchi method insert ignore into journalissuearticles values(TM);, Grey relational analysis insert ignore into journalissuearticles values(GRA); and ECHIP. Body-weight insert ignore into journalissuearticles values(gr); insert ignore into journalissuearticles values(R1);, Top Load insert ignore into journalissuearticles values(Pa); insert ignore into journalissuearticles values(R2);, Burst Pressure insert ignore into journalissuearticles values(Bar); insert ignore into journalissuearticles values(R3);, Stress Crack Resistance insert ignore into journalissuearticles values(Min.); insert ignore into journalissuearticles values(R4); and Tg insert ignore into journalissuearticles values(oC); insert ignore into journalissuearticles values(R5); were consiedered as performance parameters. The experimental design proposed by Taguchi involves using orthogonal arrays. An L9 orthogonal array was chosen for the procedure. Primarily, the performance parameters were optimized with the ECHIP Design of the Experiment insert ignore into journalissuearticles values(DOE);. Thereafter, all of the factors were optimized together with TM, GRA and ECHIP.
