High-Accuracy Sheet Metal Punching Services at Sumiparts SAS
Sheet Metal Punching with CNC (Computer Numerical Control) technology is one of the key precision manufacturing processes we perform at Sumiparts SAS, leaders in industrial metal fabrication and processing. This advanced method allows us to achieve highly accurate, repeatable, and efficient results, making it ideal for complex industrial, architectural, and automotive applications.
Thanks to the computerized control system, every detail of the punching process is precisely programmed, ensuring a minimal margin of error through careful machine calibration and specialized punching software. This results in consistent dimensions, clean cuts, and superior quality finishes across all production runs.
At Sumiparts SAS, our CNC Sheet Metal Punching service can be applied to a wide range of materials, including stainless steel, carbon steel, aluminum, and galvanized sheet metal. The process supports multiple operations such as lattice punching, cutting, trimming, and die-cutting, always maintaining the highest standards of precision and surface finish quality.
To optimize performance and cost efficiency, we utilize an extensive library of punch tool references, allowing us to adapt each project to its specific geometry and material thickness. This strategic tool selection not only guarantees dimensional accuracy but also helps reduce material waste and production time, resulting in greater efficiency and cost savings for our clients.
Whether for industrial equipment, architectural components, or automotive parts, our Sheet Metal Punching service combines cutting-edge technology, experienced operators, and strict quality control to deliver products that meet the most demanding technical requirements.
How is the Sheet Metal Punching process done?
This is a work that is carried out through the sheet and plate cutting , using a punch and a die. The application of punch forces on the material to be introduced creates an initial deformation, followed by a breakage of the material due to the rapid propagation of cracks between the cutting edges of the punch. The procedure results in a fairly obvious change.
Three stages are taken into account in the sheet metal punching process:
- Sheet Metal Punching Deformation: Produced by the punch on the metal sheet during the process, which originates in an elastic deformation around the edges of the punch and the die. This initial phase is critical in understanding the mechanism.
- Sheet Metal Punching Inclusion: It occurs when the cutting edges of the punch and the matrix manage to insert themselves into the material during the sheet metal punching operation, producing cracks in it along the cutting edges. This stage represents a fundamental step in the sheet metal punching sequence where material failure begins.
- The Sheet Metal Punching Fracture: After the cracks in the sheet originate from the sheet metal punching forces, the punch continues to descend to expel the cut material. This action completes the sheet metal punching cycle, resulting in the impregnation of the slug in the matrix and the successful expulsion of the cut material, finalizing the operation that creates precise openings in the metal sheet.
Any of the advantages of the punching of sheet metal are:
- They avoid scratches on the sheet and unnecessary movements since the material circulates in only one direction.
- Variety of up to 60 punches and dies In the machines used for punching, which can rotate and be placed in position achieving better speed.
- Speed in the processes, since being an automated process it can be done for parts and mass products, or also if special developments are desired tailored to customer needs.
