Proto Precision has provided a sheet metal punching service for 40 years. Rapid processing speeds and lower operating costs can make CNC punching a cheaper profiling solution than laser cutting, depending on part complexity and batch size.
Our CNC punching machines are capable of punching materials in thicknesses from 11ga stainless/steel to .188 aluminum, and blank sizes up to 60”x120”. Proto Precision typically punches materials such as, stainless steel, aluminum, cold rolled steel, brass and copper as well as some more exotic types of sheet metal. Using computer-assisted part nesting allows maximum material utilization.
