1. Structural manufacturability of fine blanking parts (sharp corners, thin walls, suspended walls, dimensional tolerances, etc.).

2. Materials of fine blanking parts (material quality, material thickness, hardness, plasticity, surface quality).

3. Structure of fine blanking die (strength, stiffness, die guide, small punch guide, exhaust and lubrication).

4. Mold material (material, carbide size and uniformity, hardness, toughness).

5. Mold manufacturing (mold blank forging, processing technology, heat treatment, wire cutting, grinding, assembly).

6. Production operation (mold height, pressure, speed, feeding accuracy, blank cleaning, lubrication).

7. Mold maintenance (reasonable storage, reasonable grinding, cleaning, stress tempering, rust prevention).
