HI, Am unable to get a part for my LG dishwasher. Figured i could repair th
e same if i could find a way to split open an ABS body impeller that has a
worn out seal......the hitch is that the 2 parts have been fused together b
y a heating method possibly without using any glues (cant find any traces o
f glue). The fused parts are about 5 mm wide and about 1.5mm thick individu
ally. its a spherical part about 6 inches in diameter and only the outer 5
mm seems to be fused as its hollow inside to house the impeller and related
Need a clean split of the fused parts as i would have to rejoin the same po
Any suggestions would be gladly accepted......

If they were heat-welded like that intentionally during manufacturing, they
would for all intents and purposes become 1 part. So, your chances of cleanly
splitting them are slim to none. Are you hoping for a bad weld?

Might as well cut them anywhere with a saw and then try to glue
it back together. Doesn't sound like something I'd do on a dishwasher
pump. Is it that a new pump is unavailable or just too expensive?
Try Ebay for a replacement pump?
The components of the part are fused together using ultrasonic
welding. This is one of the strongest and most reliable ways of
joining plastic pieces.
You could try using a jewelers saw or a razor saw and then bond it
back together with epoxy, however if the impeller spins at high RPM,
balance might be an issue as well as the bonding product used.
