Our team accepts a task from an native marine equipment factory, helping them to develop a mold to produce a detector which need to work in sea water for years, so it must be water proofing.

The first problem is how to keep the black epoxy resin part not bending when injecting, it will cause white resin thickness not even.

The second problem is how to decrease the injection pressure, if the pressure is big, the magnet ring will break, that is not allowed.

After 3 months hard working, our team provide a perfect solution, It’s good that we make another progress in over mold application for electronic device water proofing.
