Stamping molds aren't all built the same. A die that runs beautifully in one shop can tear strip or snap punches in another. Why? Press condition, material variance, feed alignment - small variables, big consequences. We build stamping molds that account for these realities. Our approach is simple: specify the right tool steel for the actual job, hold clearances that survive real-world press deflection, and polish wear surfaces so material flows instead of galls. If you're punching, blanking, bending, or drawing sheet metal in any serious volume, the mold you put in the press matters more than the press itself.
Stamping Mold Types We Manufacture
| Mold Type | Best For | Typical Cycle Time | Our Standard Features |
|---|---|---|---|
| Progressive Die | High-volume complex parts (500,000+ pcs/year) | 20–60 strokes/min | In-die tapping capability, mis-feed detection, modular inserts |
| Compound Die | Flat blanks with holes; high concentricity needs | 30–80 strokes/min | Single-station blank/pierce, integrated stripper plates |
| Deep Drawing Die | Cylindrical or box-shaped parts with depth | 15–40 strokes/min | Variable blank holder pressure, staged draw reduction |
| Transfer Die | Large panels or parts requiring multiple draws | 10–25 strokes/min | Mechanical finger transfer, independent station adjustment |
| Bending / Forming Die | Brackets, clips, chassis components | 30–60 strokes/min |

What Goes Into a Dongfang Stamping Mold
Design Verification: We simulate strip layout and forming stress before cutting steel. Catches thinning and springback in the virtual stage.
Vacuum Heat Treatment: No surface oxidation. Hardness is uniform, not just on the outside.
Deep Cryogenic Treatment (Optional) : For precision parts that can't afford to drift after 50,000 hits.
Wire EDM for Complex Cavities: *±0.005mm contour accuracy for tight-tolerance features.*
Full Assembly & Tryout: We run sample parts on a press similar to yours before shipping.

Quick Answers
Q: Progressive die or compound die - which one do I need?
A: High volume + complex shape = progressive. Lower volume + simple flat part = compound. Send us the drawing and we'll tell you within a day.
Q: Can you repair or modify an existing mold?
A: Yes. We replace worn inserts, regrind cutting edges, and update tooling for design changes.
Q: How do you ensure the mold fits my press?
A: We ask for your press specifications upfront and build to your shut height and mounting pattern.
