Compound Die

Compound Die Manufacturer - Shreeji Gears

Precision Compound Dies

Shreeji Gears excels as a compound die manufacturer, designing and building high-precision tooling for demanding sheet metal stamping. Compound dies uniquely perform multiple cutting operations (e.g. blanking and piercing) within a single press stroke.

This design ensures exceptional accuracy in the relationship between features cut simultaneously, making them ideal for parts requiring high concentricity. We use premium tool steels and meticulous manufacturing for maximum die life.

Choose Shreeji Gears for advanced tool and die solutions.

Understanding Compound Dies

A compound die performs two or more cutting operations (like blanking an outer shape and piercing inner holes) at a single station during one press cycle. The cutting elements for these operations are integrated within the upper and lower die sections, acting simultaneously.

Key Advantages:

  • High Accuracy: Delivers excellent precision between features cut in the same stroke (e.g., concentricity of a hole within a blank) because the material doesn't move between cuts.
  • Suitable for Flat Parts: Primarily used for producing flat components where feature relationships and flatness are critical.
  • Single Station Efficiency: Completes multiple cuts without needing the long setup of a progressive die.

Considerations:

  • Complexity: More complex design and construction than simple dies, requiring higher precision in manufacturing.
  • Slower Production Rate: Typically slower than progressive dies due to the part ejection process required after each stroke.
  • Limited Forming: Primarily used for cutting operations; complex forming is not feasible.
