Example: Production of table knife blades



  1. Cutting blade (Eccentric press 600 kN)
  2. Upsetting (Upsetting machine WES-105)
  3. Forging / calibrating bolster (Friction press 2500 kN)
  4. Trimming blade (Eccentric press 500 kN)

Financial advantages of electro-hydraulic upsetting procedure



  • Reduced investment expenses
  • Lower tool costs due to reduced wear
  • Savings in material, energy and operating expenses
  • Reduction of production tolerances
  • Savings in personnel / investments
  • Optimal expandability of production up to full-automation
  • Improvement of environmental conditions

Qualitative advantages of electric upsetting



  • Accumulation of sinter is being reduced, since heating of workpiece starts from the center of material.
  • This way a longer lifetime of forging tools is ensured.
  • During the upsetting process material fibres form without fracture according to shape required.
  • The core structure and size remain unchanged due to the characteristics of resistance heating.
