ISBM production defects are not random. Every defect has a defined set of root causes \u2014 and adjusting parameters without identifying the correct cause first wastes time, material and machine capacity while the actual problem continues. This guide takes a root-cause-first approach to the ten most common defects encountered on one-step injection stretch blow molding machines. For each defect, we identify the physical mechanism behind it, the process variables that cause it, and the corrective actions ranked from fastest to implement to most involved. The emphasis throughout is on ISBM-specific failure modes \u2014 many of which differ significantly from those encountered on two-step reheat blow or injection blow molding lines.<\/p>\n
