Component Specifications

Definition
The Upper Die is a precision-engineered component that mounts to the press ram in a die set, working in conjunction with the lower die to perform cutting, bending, or forming operations on metal workpieces through controlled mechanical force.
Working Principle
The Upper Die operates by descending under press force to engage with the lower die, applying compressive stress to deform or cut the workpiece material according to the die cavity geometry, then retracting to allow part ejection.
Materials
Tool steel (D2, A2, or M2 grades), carbide inserts for wear surfaces, heat-treated to 58-62 HRC for durability.
Technical Parameters
  • Surface Finish Ra 0.4-0.8 μm
  • Weight Capacity Up to 5000 kg
  • Operating Pressure 100-2000 tons
  • Guide Post Diameter 40-100 mm
  • Dimensional Tolerance ±0.02 mm
Standards
ISO 9001, DIN 9835

Frequently Asked Questions

What is the difference between Upper Die and Lower Die?

The Upper Die attaches to the press ram and moves downward, while the Lower Die remains stationary on the press bed; together they form the complete die set for metalworking operations.

How often should Upper Dies be maintained?

Regular inspection every 50,000 cycles, with preventive maintenance including lubrication and wear checking; complete refurbishment recommended after 500,000 cycles depending on material and operation severity.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
