Block for LiB Punching Dies

Tungsten carbide blocks are crucial for Lithium Battery (LiB) punching dies due to their extreme hardness, wear resistance, and toughness, enabling precise cutting of battery components like anode/cathode foils and separator films. CYC carbide grade delivered outstanding performance for high edge retention, anti-galling properties, and resistance to adhesive wear in demanding conditions

Advantages & Benefits:

• High Wear Resistance: Resists abrasion from continuous punching, extending tool life.

• Toughness & Strength: Balances hardness with fracture toughness to withstand shock loads without chipping.

• Precision: Allows for extremely tight tolerances, critical for consistent battery performance.

Applications in LiB Manufacturing:

• Punching electrode materials (anode/cathode).

• Cutting separator films.

• Creating battery case components (e.g., 18650, 21700, 46800 formats).
