We used to receive many RFQ (Request Of Quotation) from our customers asking for price offer. If you study the prints carefully, you may see some sheet metal components were designed in the bed way bend. The bend radii are stated as sharp or only a small radius is allowed. When we spotted this...

A good way bend and a bad way bend – Sheet metal forming
Spring back in metal bending (II)
Some readers wrote to me after reading my previous post on “Metal forming spring back”. The technique I mentioned in the post was used on a progressive tool it is not suitable in the single forming tool. Some of the factors for successful bending are the size of interior bend radius and the metal...

Calculation of flat blank length in press tool design
In any press tool design, the first thing to consider is how to determine the flat blank length of the folded component. I won’t go into the boring theory of how the material behaves during bending and how the individual material property affects the length and spring back. To be frank, I hate all these theories! During the bending...
