Internal water lines tend to cause the mold to sweat as condensation forms on the mold platens and cavity. Rust and oxidation can begin to form almost immediately, even before the mold can be taken out of the machine and returned to the tool room.
To help prevent sweat from creating rust during cool down, simply apply Rust Preventative to the mold cavity once temperatures are reduced.
Once the mold reaches room temperature, the mold should be flushed and cleaned thoroughly with a mold cleaner. Then apply a fresh coat of rust preventative.
Preventing corrosion on mold presses, slides, lifters, moving cores, and hydraulic and mechanical systems is essential to keeping your expensive injection molding systems running well.
We carry a large selection of Rust Preventatives for every application.
