Lance-N-Loc® Clinching Joint Cross Section
Lance-N-Loc™ is good for joining harder materials, multiple layers, and is ideal for use where electrical conductivity is required.
Lance-N-Loc® is a sheet metal clinching system which creates a strong mechanical joint without the use of external fasteners or welding. The metals are lanced and squeezed to form an interlock below the bottom layer of the sheet metal.
Lance-N-Loc® is good for joining harder materials, multiple layers, and is ideal for use where electrical conductivity is required.
The final result is a joint with a greater width than the drawn section of the metals. This accounts for the high strength of Lance-N-Loc® joints. The entire sequence takes place in a single press stroke.
- Clamps: The first step in the process involves the clamping of the material with a punch side stripper.
- Draws: Next, the punch draws the material into the die.
- Locks: As the material flows into the die, the die blades expand, allowing the metal to flow into a strong interlock below the bottom sheet.
