|corrosion rates of steel inserts in plastic overmolds
Posting by mike on May 22, 2008 at 18:22:19.
I have a possible overmold application where i want to insert mold/ overmold a Silicon steel stator lamination in a pump application... the concern is the service life time of the stator as water is absorbed/ diffused/ permeates thru into plastic and thru to the this stator. The added complication is 110 C water temperatures/ Ph 1.5 to 11/ and 175 psi service pressures. is there any applications like this and what are the expected lives of the insert? any technical work done on the corrosion of metal inserts encapsulated in plastic, and the related lifetime prediction or expectation?
