Major Consideration

The wall thickness of plastic bottle is a major consideration for engineers in designing products with strength. For injection blow molding, the thickness depends on the preform size, and shape of the required product. The polyethylene terephthalate (PET) is injected in a mold with the shape of the preform. A stretch injection blow molding machine is used for processing the preform to the shape of the bottle. This research applied finite-element analysis for the process simulation; started from applying the air pressure inside the heated perform – until the PET expanded to the required bottle shape. While most studies were interested in axis-symmetry shape, this paper concentrated on a bottle with uniform flat wall thickness on four sides of a squared section bottle. Several finite-element models were studied and compared the simulation efficiency. Under the investigated area of ±15 mm x 90 mm, the thickness deviation found to be within 3.573%.

Previous Experimental Study

Abstract This study was carried out in two stages. In the first step, a numerical study was performed to verify the previous experimental study. In accordance with the previous experimental study data, single lap joints models were created using the ANSYS finite element analysis program. Then, nonlinear stress and failure analyses were performed by applying the failure loads obtained in the experimental study. The maximum stress theory was used to find finite element failure loads of the single lap joints models. As a result of the finite element analysis, an approximate 80 % agreement was found between experimental and numerical results. In the second step of the study, in order to increase the bond strength, different overlap end geometry models were produced and peel and shear stresses in the adhesive layer were compared according to the reference model. As a result of the analyses, significant strength increases were calculated according to the reference model. The strength increase in model 3 and model 5 was found to be 80 % and 67 %, respectively, relative to the reference model.
