Dimple Forming

Dimple forming is a specialized metal fabrication process used to create recessed or raised features in sheet metal. These dimples improve structural strength, provide fastener clearance, and enhance alignment or fit during assembly, all while maintaining a clean, uniform appearance.

How It Works

The dimple forming process begins with a prepared hole or marked location in the sheet metal. Using matched punch and die tooling or press equipment, controlled force reshapes the material into a consistent dimple profile without removing metal. The tooling draws material inward or outward to form the desired depth and diameter. Proper setup, tooling alignment, and material control ensure that dimples are formed evenly and repeatably across parts and production runs.

Quality & Accuracy

Dimple forming delivers uniform depth, diameter, and alignment, maintaining tight tolerances and consistent appearance. Because material is displaced rather than removed, the process preserves material thickness around the feature while reducing stress concentrations. Careful process control ensures minimal distortion and maintains overall part flatness and dimensional integrity.

Benefits

This process enhances part strength and durability while improving fastener seating and assembly quality. Dimple forming reduces the need for secondary operations and provides a clean, professional finish. It is suitable for steel, stainless steel, aluminum, and other sheet metals and supports both prototype and production fabrication. Dimple forming is ideal for applications requiring reliable fastening, improved load distribution, and consistent feature geometry.
