To realize the maintenance management system in the near future, this paper presents a development of on-line computer maintenance system to manage and record the maintenance information in the database for the plastic injection machines by utilizing the computer networks via the wireless system. The on-line computer maintenance management system is friendly use and easy to check the equipment problems, the production wastes and the production efficiency via the mobile phones and also the computer networks. Whenever a malfunction happens, the alert message will be sent to the operator and the maintenance manager to respond it immediately. In addition, the developed energy management function by selecting the heater insulator and reducing the mold clamping pressure can help to calculate the energy consumption, the breakeven point and the payback period which have not been done in the computer maintenance management system. The developed program can automatically generate the next schedule of the preventive maintenance, which leads to the higher efficiency. The developed system is examined and implemented in the plastic injection machines, which have never been used the on-line computer maintenance management system. It has been proved that the proposed and developed system increases the overall equipment effectiveness about 6.42% and the mean time between failure of 37.17% while the mean time to repair decreases approximately 16.26%.
