Easy method of removing ferrite core

[isa_olcer]

An easy method to remove the ferrite core. Contact or even move to the core of the lamp series, and wait 1 minute. Use a minimum of 65W lamp. Remove the ferrite core heated Be careful when!

I really like the Idea.

This way I will be able to dissemble any core, today will make a test

..in my place we use Acetone (nail polish remover) just soak the core for about 20-30mins or longer.

..nice info isa_olcer..

Almost same technique. I use lacquer thinner instead of acetone.

I used hot air gun to heat the core & remove it after that.

Does the core suffer any deterioration due to the heat?

Does any Member that knows the answer want to tell me?

I am not sure if I understand your question properly, but I had no problems with big cores, small cores may crash is you over heat.

Hope that helps

.........I had no problems with big cores, small cores may crash is you over heat.

looks like you are confirming that some types of core, or sizes of core, can be affected by heat.

Can you or anyone else give us some guidance on maximum acceptable temperatures to avoid killing our cores?

I simply put it in heating water, eventually boiling if it is a cheap chinese Xformer. Otherwise I use the oven, heating it to aboutish 125 C and then the binding resins soften.
