A blow moulding machine preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the blow moulding machine fails. This page gives the schedule used in the PlantOps360 task library for blow moulding machine (extrusion blow, stretch blow, pet), which follows common industry practice for general-purpose equipment. It is also searched for as blow moulding, blow molding, ISBM, PET bottle blowing.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.
