Customizing bending tools to meet specific job requirements can be challenging. Consulting a design engineer with experience in this area can be a cost-effective solution. By specifying the required angle, radius and tolerance, the engineer can customize the tool to meet the specific needs of the job at hand.

Selecting the appropriate bending tool radius is critical to ensure optimal bending performance. Typically, the punch tip radius should be at least 60% of the material thickness. For air bending of sheet metal, the minimum achievable inside radius is 0.60 times the material thickness.

Efficient bending of Z-shaped parts on a plate bending machine can be achieved using a standard punch and die if the part size is relatively large. However, if a one-time solution is required, the offset tool may be required. GUNNARPRESS offers a wide range of standard offset sizes, including four standard angles of 90, 140, 150 and 160 degrees, as well as straightening inserts to suit a variety of bending requirements.
