Abstract

Several kinds of defects that occur in bottle industry will reduce efficiency of bottle production. The defective bottle products are caused by several factors, such as human error, compositions, faults in temperature and machinery setting. From such those errors, faults in temperature and machinery setting often occur during bottle fabrication. This research aims to simulate bottle fabrication by using Computational Fluid Dynamic (CFD) and being used to predict loading mark bottle defect. The results indicate that the temperature range in counter blow process should be 600-800°C and in order to reduce the inhomogeneous parison temperature distribution the proper air velocity should be 0.1 m/s. The inhomogeneous parison temperature distribution at the contact area between parison and blank mold may lead to the presence of loading mark. Based on the simulation results, the loading mark is likely to take place at the shoulder and neckring of the bottle.
