I need some confirmation

[Suzuki4evr]

I am not sure yet how I am going to bill this apart from material price,so I am not sure if the profit will be enough so that buying a bender will be justified.

Great thread Suzuki, good information gathered.

I would cut a piece exactly 40mm long and put a bend in the center and measure each side to determine what is changing. At work we use a top die with a 094" radius. This will generally add one material thickness to each side of the corner.

Why 40mm?

We need a bit more info to make any recommendations.

two more dimensions: sheet thickness, and length of bend.
material type will affect the strength of machine required

Brino in my first post I think I mentioned thickness at 0.9mm stainless steel sheet and the internal length is 110mm with sides of 19mm from internal base to the top of the side.

I do have a pneumatic hydraulic 10ton press.

Draw it up in OnShape using the sheet metal feature, it'll tell you exactly where you need to be heading given your desired bend radius and K factor for the material.

Pardon me,but is this a computer program?

Sorry Michael it's my fault; I entirely missed the thickness and material you stated.
I need to slow down and read better.

But we're still missing the length (or is it width?) of the bend right?
(ie. do you need a 200mm brake or a 1000mm brake to do this.)

My apologies,

You are apologizing too much my friend. No worries here.

I will put it like this if I am a bit unclear. The bended side is 19mm long basically and the strip is 19mm wide and the internal length is 110mm. My client uses it as a mold of some sorts to make fire lighters from some specil cement and the end product is 110mm×19mm×19mm. Hope this helps for clarification.

Don't worry we are still friends

As to the original question about dimensions, here is a SolidWorks drawing reflecting the final dimensions and the flat sheet dimensions. I made some assumptions as to bend radius and width. but you get the idea.

Edit: I used .8mm instead of .9mm for the thickness on the drawing. The second drawing reflects a .9mm thickness and I also changed the inside bend radius to .25mm.

Thank you very nuch RJ for this, I realy appreciate it. O the width is also 19mm. Once again thank you.
