In this article, we made an injection molding machine maintenance pdf checklist for operators to maintain their injection molding machines. According to this checklist, you will know where to check and maintain it.
Lubrication System
√Lubricating oil pipe → Check in good condition
√Lubrication oil pump → Check pressure normal
√Linear guides → Check lubricating grease enough
√Lubricating pump filter and oil pipe filter → Clean
√Clamp mechanism → Check lubricating grease enough, cleaning off the old grease.
√Oil pump filter → Clean
√Mold adjusting mechanism → Check the lubricating oil enough
√Pre-molding motor → Check the lubricating oil enough
Hydraulic system
√High-pressure oil pipe → Check in good condition
√The oil cylinder seal and piston rod → Check in good condition
√Return oil pressure → Check the pressure ≤4.5 bar
√Oil temperature → Between room temperature~50℃
√All valves → Check in good condition
√Hydraulic motor and mold adjusting motor → Check motors are in good condition
√Oil pump → Check the pressure and speed are normal
√Oil pump motor oil filter → Check in good condition
