Stamtec iS1 Series Direct‑Drive Servo Press

High‑Precision, Programmable Servo Technology for Versatile Forming Applications

The Stamtec iS1 Series is a single‑point, straight‑side, direct‑drive servo press designed for manufacturers who require 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 iS1 Series delivers full working energy even at low speeds and dwell positions, enabling superior control over material flow and forming characteristics.

With a wide range of programmable motion curves and forming modes, the iS1 Series is ideal for applications requiring precision, repeatability, and the ability to perform multiple forming operations within a single press.

Key Features & Benefits

Direct‑Drive Servo Motor System

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

Programmable Motion Profiles

The iS1 Series supports a wide variety of forming modes, including:

• Crank mode
• Link mode
• Coining mode
• Drawing mode
• Fine blanking mode
• Pulse 1 & Pulse 2 modes
• Swing forging mode
• In‑die heating mode
• Feeder mode
• Pendulum mode

Custom motion curves can also be created, with up to 20 programmable segments defined by position, speed, and dwell duration.

Enhanced Forming Capability

• Lower slide velocity in forming zones improves material flow
• High‑speed movement through non‑forming zones increases productivity
• Supports secondary in‑die operations such as drilling, tapping, staking, welding, and assembly
• Reduced die impact for quieter operation and longer tool life

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
