Pay attention to water leaks and rust, proper grease selection, vent buildup, and checks for wear.
Proper O-ring maintenance is important to prevent rust. O-rings degrade over time, so they should be replaced each time the tool undergoes preventive maintenance.
In this column, I will discuss best practices for cleaning and maintaining the mold in the press to reduce downtime from part scrap and tooling issues. Last month I covered design of water lines and moving components to reduce maintenance issues. Water also deserves considerable attention in terms of maintenance procedures.
Water from leaks or condensation can cause a lot of damage to a mold and cavities. I myself have dealt with hundreds of rust problems from water leaks and condensation. Some were very severe and cost thousands of dollars to repair and a lot of personal stress in dealing with downtime and trying to make quality parts. If the issue is caught soon enough, a light surface rust is not a major issue. But if the water or condensation is allowed to sit long enough it can cause major damage.
