Two‑Point, Straight‑Side Servo Press for High‑Precision, High‑Flexibility Forming

The Stamtec iS2 Series is a two‑point, straight‑side, direct‑drive servo press designed for applications requiring exceptional forming flexibility, programmable motion control, and high‑precision performance. By replacing the traditional flywheel, clutch, and brake with a high‑torque, low‑RPM servo motor, the iS2 Series delivers full working energy even at slow speeds and dwell positions, enabling superior control over material flow and forming characteristics.

With its advanced servo controls, the iS2 Series supports a virtually unlimited number of stroke profiles and slide movement patterns, making it ideal for complex forming operations, high‑strength materials, and in‑die secondary processes.

Key Features & Benefits

Direct‑Drive Servo Motor System

  • High‑torque, low‑RPM servo motor
  • Full working energy available at low speeds
  • Reduced impact, vibration, and snap‑through
  • Improved part quality and extended die life

Programmable Motion Profiles

  • Up to 20 customizable motion segments
  • Adjustable slide positions, speeds, and dwell times
  • Supports advanced forming modes including:
    • Crank mode
    • Link mode
    • Coining mode
    • Fine blanking mode
    • Pulse forming
    • Swing forging
    • Pendulum mode
    • Mold heating mode
    • Feeder mode
  • Custom motion curves available upon request

Enhanced Forming Capability

  • Improved material flow due to lower slide velocity in forming zones
  • High‑speed movement through non‑forming zones for increased productivity
  • Ability to perform secondary in‑die operations such as drilling, tapping, staking, welding, and assembly

Energy Efficiency

  • No flywheel or constant‑running motor
  • Lower idle energy consumption
  • Regenerative energy system returns power to capacitor banks during upstroke

Automation‑Ready

  • Easily integrates with coil feedlines, transfer systems, robotics, and work cells
  • Supports in‑die sensing and quick die change systems
  • Ethernet connectivity and task assignment software
