What is the industry standard for a life of a molding machine?
There is no reason though, that a world-class machine cannot perform "forever" though. With the proper PM, repairs, checks and calibration, keep the press as long as it is world-class. This means periodic diagnostics as well. Proper data collection on the process also is important to judge how your press performs.
One important aspect of PM is oil analysis (of hydraulic presses of course). Have your oil tested every 6 months. If there are abnormalities, then follow through with more frequent samplings after corrective action.
Shamefully, some companies get judged by the age of their presses, rather than the documented condition.
Keep on molding!
Brent also makes one other point, molding companies get judged by the age of their presses, but this can be offset with machine capabilities, upgrades, appearance and process control documentation.
Some were done in Ohio, but not at Randall's company, I don't think he was there at the time. The results were gratifying, in one case we got a press capable of running 3.3 second cycles. This was by no means a press designed for high speeds.
What Randall writes about is a great alternative to press replacement, especially if you have older American presses and you want to stay American. Just don't neglect PM AFTER the rebuild.
I suppose that for bigger size machines this age could be increased up to 15-20 y.
aged control could be replaced (reasonable for big machines) if injection molding machine itself is in good condition (machines are not human just change a brain if necessary)
But You have to consider that service MUST be proper, and technological process balanced with machine technical capabilities.
With extreme setup without service You can turn machine to scrap very fast (3-5 years).
So... 7-10 up to 12, for standard, well serviced, medium sized machines.
