Stamtec’s 2‑Point Crank Shaft Straight Side Presses represent one of the most comprehensive and versatile lineups in the global metal stamping industry. Built on ultra‑rigid straight‑side frames and engineered for precision, stability, and long‑term durability, these presses deliver exceptional performance across a wide range of applications—from high‑speed lamination stamping to large‑format progressive dies, deep forming, and heavy‑tonnage transfer work.
Across six distinct series, Stamtec offers solutions tailored to every production requirement:
Each series is engineered with Stamtec’s signature focus on rigidity, accuracy, and long die life, supported by advanced controls, robust drivetrain systems, and industry‑leading hydraulic overload protection.
Two crankshafts distribute force evenly across the slide, making these presses ideal for:
Most series feature six‑ or eight‑point gibs, ensuring:
All models use heavy, stress‑relieved steel frames designed to minimize deflection and maintain accuracy at full tonnage.
Every series supports modern automation controls, including:
Fast‑response HOLP protects the press and tooling by relieving overload pressure in milliseconds.
The SC2 Series is designed for stamping long, narrow parts or running progressive dies that require extended bed lengths. It offers a large die area at an economical price and is ideal for applications where a straight‑side press is needed but a heavier‑duty frame is not required.
Note: All specs for the SC2 Series are based on typical ranges for Stamtec’s economical long‑bed 2‑point straight‑side presses. Specs to be confirmed with Stamtec prior to ordering
