If the bending machine is not properly selected during purchase, production costs will rise, and the expected cost recovery of the bending machine may not be achieved. Therefore, several factors must be weighed when making a decision.
Workpiece: The first important consideration is the part you want to produce. The key point is to purchase a machine that can complete the machining task with the shortest workbench and the smallest tonnage. Carefully consider the material grade, as well as the machining thickness and length.

Deflection: You also need to consider the potential deflection of this machine. Under the same load, the deflection of the 10-foot machine's workbench and slide is four times that of the 5-foot machine. This means that shorter machines require fewer shims for adjustment to produce qualified parts. Reducing shimming adjustments also shortens preparation time.
Bending radius of parts: Next, focus on the bending radius of the parts. When using free bending, the bending radius is 0.156 times the opening distance of the die. During the free bending process, the opening distance of the die should be 8 times the thickness of the metal material.
Degree: The requirement for bending accuracy is a factor that requires careful consideration. It is precisely this factor that determines whether you need to consider a CNC bending machine or a manually controlled bending machine.
Molds: Even if you have a shelf full of molds, don't assume they are suitable for your newly purchased machine. It is necessary to inspect the wear of each mold by measuring the length from the front end of the male mold to the shoulder and the length between the shoulders of the female mold.

Bending piece side length: A factor often overlooked is the side length of the material before it is bent in a bending machine.
