Also known as a press, it is an essential auxiliary processing device in cold roll forming lines. It applies high pressure to make metal sheets undergo plastic deformation or separation in dies, enabling processes such as punching, shearing, trimming, bending, flanging, and stretching on the strip or semi-formed profiles. This customizes holes, notches, or partial shapes for the product, matching the design requirements of the cold-formed profiles.
The Punching Machine provides critical deformation and shaping functions between the material feeding and roll forming stages. Utilizing matched die sets and high-speed servo control, it applies vertical force to punch or shear the metal sheet accurately before it enters the next process.
This machine supports a wide array of operations:Hole punching (round, oval, custom),Side or corner notching,Pre-form trimming or cutting,Flanging, coining, and shallow drawing
It ensures that every profile or product leaving the line meets precise hole placement and cut-out dimensions, reducing secondary processing and improving yield.
Industries relying on this solution include:Electrical cabinet production,Fire safety enclosures,PV frames and support structures,Warehouse & logistics shelving,Automotive body parts & floors
