Abstract

The frequent occurrence of unplanned maintenance of curing machine on PT XYZ car tire production line is an indication of ineffectiveness implementation of the preventive maintenance. Unplanned downtime caused increasing of lost production time and failure products during setup, and also high cost maintenance. The company must improve the effectiveness and efficiency of the maintenance system performance through updating the maintenance schedule for obtaining high availability of the machine. The purpose of this study is to identify the components which cause the failure of the curing machine and give the recommendation of the appropriate maintenance interval. Weibull distribution method is used to get the index value of fit time to failure of machine components, analyze the component failure rate, calculate the mean time between failure (MTBF) as the expected lifetime of the component. The obtained result showed that there were two critical components with an indication of the increasing failure rate, as during wear-out (β value> 1), which are namely cylinder press and EPV with an MTBF value of 89 days for cylinder presses and 231 days for EPV. The results of this study propose for updating the curing machine PM schedule. the adding pressure valve and EPV on PM activities and using the its expected lifetime as its PM interval should be considering. it will minimize unplanned downtime

Abstract

A shot blasting machine is a cleaning machine for casting products with a steel ball shooting mechanism from the impeller/blast wheel rotation's centrifugal force. As the main machine in the final process of casting production activities, the decrease in machine reliability has a negative impact on the production system. Currently, the production equipment maintenance strategy at PT ABC is still implementing corrective maintenance, which is unplanned and reactive when a machine malfunction occurs. It resulted in high production loss and increased maintenance costs. Therefore, the shot blasting machine's maintenance strategy should be changed to a type of preventive maintenance. This study aims to plan preventive maintenance (PM) system for the shot blasting machines of PT. ABC, such as creating PM schedule, calculating machine downtime, and technician needs for each PM activity. PM system planning is achieved using the ISMO (Inspection, Small repair, Medium repair, and Overhaul) method. Its method was conducted in several stages, which start with identifying machine objects, making PM work specifications, determining the value of mark complexity and maintenance cycle, calculating machine downtime and technician needs. Then making schedules annual and monthly, and several other maintenance documents. The mechanism for determining the complexity value is determined based on the similarity of the HP Garg methodology's machine specifications. Finally, The planning of the shot blasting machine PM system has been successfully done, some of the PM information obtained are (i) the machine maintenance cycle is C - I1 - I2 - S1 - I3 - I4 - M1 - I5 - I6 - S2 - I7 - I8 - M2 - I9 - I10 - S3 - I11 - I12 - C, (ii) the time interval between maintenance activities is one month, (iii) machine downtime for each shot blasting machine, (iV) the number and level of maintenance technicians required in every ISMO activity for drum shot, batch shot and hanger shot machines. The calculating verification of the shot blasting machine's availability value on the proposed PM schedule shows that machine availability increased to more than 80%.
