Punching and Stamping Services

Punching is a process that uses a CNC machine to shear, notch, and punch angles and flat bars. Porous Metal Filters utilizes state-of-the-art equipment to plasma cut, punch, drill, and tap metal components to produce items in a cost effective manner.

Punching holes with a punch press is one of the most mature technologies in metal fabrication, and yet it’s still one of the most misunderstood. Modern machines and tooling have turned the punch press into the Swiss army knife of the fab shop. It punches holes, just a few here and there or in a dense perforation. It cuts large panels. It forms louvers, embosses, and other complex shapes, and in some cases bends flanges several inches high.

Still, because the punch press can do so much, processing variables abound, and if they’re not accounted for, part quality and throughput can suffer. Understanding a few punching fundamentals can go a long way in ensuring that the multitude of processing variables remain well under control.

Our sheet and plate machines have computer numerical controls (CNC) that allow for production repeatability and are programmed from CAD software to reduce errors. Typical material thicknesses for punching is ½” thick and below.

Porous Metal Filters offers CNC metal forming and bending services to produce components and fabricated parts for subassemblies. From simple 90° bends to complex sequences with multiple bends, our press brakes can form small and large parts.

Technology, skill, and process controls allow formability and repeatability to meet customer demand. PMF can handle a wide range of material grades, thickness, and sizes.
