PT.X is a manufacturing company that makes plastic containers of plastic bottles as a packaging (packaging). The resulting product was based on requests from customers with a product specification is very clear and complete. PT.X required to produce the appropriate level of quality standards set by the consumer.Problems faced by PT. X is still reject the presence of the products produced. Having explored reject that occur in production due to malfunction of components. Based on data from downtime is known that machines that have the greatest there is downtime on the machine SB-03 stretch blow XLPMMP (XY4-2). It required a maintenance schedule to address the
problems that occurred in PT.X. The next step after knowing the critical engine is to determine the critical components that affect the quality of the product by using the fault diagnosis. Critical components on the machine is
UHS seals, stretc h blow stick, neck seal sealing, mold clamping bolts, light heater, cylinder tube stretch, DHS seal,, oring, push button switches, as tie bars, As mold clamping cylinder, hose blow, stretch blow seals, valve stretch blow norgen. The next step is to conduct FMECA analysis to determine the cause of failures, failure effects and determine the level of criticality of the component.Determination of the critical components of the assignment to be done by using a diagram RCM II. Schedule discard the task done for blow hose components, sealing neck seal, as tie bars, mold clamping bolts, heater lamps, sticks stretch blow, stretch blow seals, as mold clamping, the DHS seal, UHS seals, oring, and push button. Schedule the task done for component restoration cylinder tube stretch blow and stretch blow valve. Based on calculations obtained maintenance scheduling replacement intervals for components of the heater lamp after 1657 hours of operation, component hose blow after 873 hours of operation, sealing the neck seal is 1554 hours of operation, seal stretch blow operasiv 1854 hours,1892 hours of stretch blow valve operation, the mold clamping bolts 1750 hours of operation, as the tie bar 2476 hours of operation, as 1977 hours of operation clamping mold, stretch blow stick 951 hours of operation, stretch blow cylinder tube 1690 hours of operation, oring 3450 hours, push button 211 hours of operation, 1835 hours opersi UHS seals, sealDHS 2837 operating hours Through the calculation of availability, the highest total value is in stretch blow valve component that is equal to 99.913% and the lowest availability in the DHS seal components of 99.691%. |
