Punch Types by Shape:Round punches、Square punches、Pentagon punches、Hexagon punches、Octagon punches、Dodecagon (12-sided) punches、Plum blossom (multi-lobe) punches、Step punches (mother-child type)、Star-shaped punches、Other special-shaped punches

Ejector Pins (Knockout Pins):
Primarily used in die production to eject finished parts from molds. Common materials include tool steel, carbide, and ceramic.

Guide Pins (Leader Pins):
Serve positioning, ejection, and guiding functions, typically manufactured from high-quality alloy steel.

Applications:
Widely used in automotive, appliance, machinery manufacturing, and other industries – essential tools for production lines.

Key Features:

• Material versatility for diverse operational demands

• Precision-engineered geometries for complex fastener forming

• Critical role in automated high-volume production

• Industry-proven reliability across manufacturing sectors
