That depends on what it is made out of. Some casting materials are like stone, others like rubber. It also depends on the shape, size, and thickness of the part.

how durable would the final product be?

Yes, but it would be a challenge. Keeping the inside and outside mold walls evenly spaced so that the finished part has uniform thickness would be difficult. It would also be a costly mold. Why not fabricate it out of sheet plastic?

A simpler method might be, placing a clear plastic tube in the mold and casting around it. Then the LED's can be inserted in the tube.

That kind of mold would require a core piece of mold material down the center core of the sword mold. That would pose two problems: One, how to keep the core centered so that the wall thickness of the cast part does not vary, and two, how to remove the piece once the sword is cast. The friction would be so great, it would probably break the cast piece upon removal.

I want to make a mold so that I may pour plastic into it, but also have a hollow mold. This is for some prop swords I am making for cosplay that I am going to put LED lights inside of. How would I go about doing that?

can this method be used for make a big plastic PC case cover about 350 x 350 mmm in size and 100 mm in depth ?

Google 'low-melt metals'. There are a variety out there. Unfortunately, TAP does not carry any.

can you suggest some metals that are under 350 degrees? Can I order them online?

We dont know. Try it and let us know. Thanks.
