One Tooling Solution for Bending and Hemming
One Tooling Solution for Bending and Hemming
Many sheet metal manufacturers face this problem: one part needs a normal V bend, but the side edge also needs to be flattened or hemmed. If standard tooling is used, the operator may need several bending steps, repeated positioning, and extra handling.
This often leads to unstable angles, poor edge alignment, surface marks, slow production, and higher labor cost. In some cases, the part looks simple on the drawing, but the actual forming process becomes difficult because the bending and hemming features are too close to each other.
A V compound die is used when sheet metal parts require both V bending and side hemming in one forming process.
A V compound die can help solve this problem by combining V bending and side hemming in one tooling structure.
What Is a V Compound Die?
A V compound die is a special type of press brake tooling designed for sheet metal parts that require both V bending and hemming. Compared with standard brake press dies, this tooling can support normal bending while also helping form or flatten the side edge.
It is especially useful when the workpiece has a closed edge, safety edge, reinforced flange, or special forming structure. With the right die design, customers can reduce extra processes and improve production consistency.
Why Standard Dies May Not Be Enough
Standard press brake tools are mainly designed for common bending work. They may not provide enough support when the part requires bending and side hemming in a compact area.
If the brake bending tool is not matched to the product structure, customers may face:
Unstable bending angles.
Side edge not fully flattened.
Poor workpiece positioning.
Scratches or marks on the surface.
Low efficiency due to multiple forming steps.
Inconsistent results during batch production.
For these cases, custom tooling press brake solutions are often needed to make the forming process more stable.
Benefits of a V Compound Die
A properly designed V compound die can help customers improve both quality and efficiency.
It can reduce repeated positioning, shorten the forming process, improve edge consistency, and make the finished part closer to the drawing requirement. It can also help reduce operator adjustment time, which is important for batch production.
For sheet metal parts with a side closed edge or hemming requirement, choosing the right press brake tooling can make a big difference in production stability.
Shengpu Tooling’s Solution
Shengpu Tooling manufactures custom press brake tools, brake press dies, brake bending tool solutions, and special tooling press brake systems for non-standard sheet metal forming.
For a V compound die with side hemming function, we can design the tooling according to your product drawing, material thickness, bending angle, hemming position, flange size, forming direction, and press brake clamping system.
If your current tooling cannot complete V bending and side hemming smoothly, Shengpu Tooling can help review your drawing and provide a suitable custom solution.
