Having said that, on account of variants in the fabric thickness for bending, the identical punch and die can not be utilized for a person-time bend forming.
(mm) that is needed for this kind of specifications. Every operation wants a certain tonnage per meter. This is often also revealed during the desk. You may see that thicker elements and more compact inside radii demand much more drive or tonnage. The highlighted options are proposed technical specs for metal bending.
Even so, for people who worth quality and direct time, RapidDirect could be your golden fleece. With our engineering aid, you could flip your types into reality and shoot on your own in excess of your competition in no time.
