Hemming Punch And Die

Hemming punch and die sets are specialized tools used in press brakes to create hemmed edges in sheet metal. This process involves folding the edge of the material back onto itself, providing increased strength, a finished appearance, and often improved safety by eliminating sharp edges.

Key Features
Design
The punch typically has a flat or slightly curved tip that matches the hem die, allowing for a precise fold.
The die is designed to accommodate the thickness of the material and the specific hem profile.
Material
Made from high-quality tool steel or carbide to withstand the stresses of bending and ensure longevity.
Surface treatments (like nitriding) may be applied to enhance wear resistance.
Compatibility
Must be compatible with the specific press brake model and the material being processed.
Available for various material thicknesses and widths.
Types of Hemming Punch and Die Sets
Standard Hemming Sets
Pre-configured tools designed for common hemming applications.
Custom Hemming Sets
Tailored to specific project requirements, allowing for unique designs and profiles.
Adjustable Hemming Dies
Features that allow for adjustments in the hem angle or depth for greater versatility.
Benefits
Enhanced Strength: Hemming increases the structural integrity of edges, making parts more durable.
Improved Aesthetics: Provides a clean, finished look to the edges of fabricated parts.
Safety: Eliminates sharp edges, reducing the risk of injury during handling.
Maintenance Tips
Regular Inspection: Check for wear, chips, or deformation to maintain accuracy.
Cleaning: Keep tools clean and free from debris to prevent contamination.
Proper Storage: Store tools in a dry, protected environment to avoid rust and damage.
