As a consequence of the state-of-art machining equipment and advanced hardening technologies utilized by Emhart Glass, the operating life of many components can now far exceed that in the past. Furthermore, intelligent control systems can protect mechanisms from damage. However this does not mean that maintenance can be neglected. Even if the machine continues to run into its old age, inevitably tolerances will be exceeded and production rates, downtime and pack rates will suffer. Taken together, these production losses will exceed the cost of maintaining equipment before it fails. Worn pneumatic parts cause substantial leakage, resulting in increased energy costs. Properly maintained equipment can significantly reduce this wastage, making an additional contribution to the positive return on investing in maintenance and repairs. To preserve the optimum cost-per-container standards, it is essential that equipment be maintained on a regular basis.
