Stamtec’s 1‑Point Gap Frame Presses deliver the durability, precision, and long service life required for today’s stamping operations. Built with a low‑inertia drivetrain and premium‑grade components, these presses offer smooth, quiet operation and tight running tolerances—ideal for a wide range of metal forming applications.
PRI is proud to offer Stamtec’s complete 1‑point gap frame lineup, including the OCP Series and the GL1 Link Motion Series, both engineered for reliability and high‑speed performance.
Stamtec’s 1‑Point Gap Frame Presses are engineered for high‑speed production of small and medium‑sized stampings, offering the ideal balance of rigidity, accuracy, and long‑term reliability. These presses are built on a compact, stress‑relieved C‑frame structure that minimizes deflection, maintains slide alignment, and delivers consistent part quality—even at high single‑stroke or continuous production rates.
To meet a wide range of forming requirements, the 1‑point platform is available in two distinct series, each optimized for different applications:
A robust, versatile line designed for general stamping, blanking, and progressive die work. The OCP Series uses a traditional crank‑motion drive and a high‑performance wet clutch and brake system to deliver smooth operation, fast cycling speeds, and long service life.
A precision‑focused line featuring link‑motion drive technology that slows the slide during the working portion of the stroke. This controlled forming motion improves material flow, reduces impact and vibration, enhances part quality, and extends die life—making the GL1 Series ideal for deeper or more complex forming applications.
Together, these two series give manufacturers the flexibility to choose the forming characteristics, speed profile, and performance features that best match their production needs—all within the proven reliability of Stamtec’s 1‑point gap frame platform.
Information on each series is detailed below.
The Stamtec OCP Series is a proven family of single‑point gap frame mechanical presses designed for high‑speed production of small and medium‑sized stampings. These presses combine a rigid, stress‑relieved steel frame with a high‑performance wet clutch and brake system, long precision gibs, and a compact footprint that allows more capacity in less floor space.
With models ranging from 35 to 300 tons, the OCP Series delivers the accuracy, reliability, and uptime required in modern stamping environments—whether running blanks or coil stock, in single‑stroke or continuous modes.
The wet clutch and brake system delivers full torque at lower air pressure, reducing wear and air consumption. The enclosed oil bath dissipates heat efficiently, supporting higher single‑stroke rates and extending lining life.
A rapid‑response overload system instantly relieves excess tonnage and stops the press to protect tooling and press components. Resetting is simple, allowing operators to return to production quickly.
The one‑piece welded steel frame minimizes deflection under load, improving part accuracy and extending die life. The compact design allows more presses to fit within the same floor space compared to traditional C‑frame machines.
Extra‑long gibs guide the slide throughout the working stroke, maintaining alignment and eliminating lateral thrust—even under off‑center loading.
Standard presses include a modern touchscreen control system with full programmability for setup, diagnostics, and safety. Controls from major brands such as Allen‑Bradley, Siemens, Mitsubishi, Wintriss, and Link are available.

The Stamtec GL1 Series is a family of single‑point, C‑frame mechanical presses engineered with link‑motion drive technology to deliver superior forming performance, improved part quality, and extended die life. Designed for small to medium‑sized stampings that require deeper draws or more complex forming, the GL1 Series combines slower working‑stroke velocity with high overall production rates—making it an ideal choice for demanding applications.
With models ranging from 88 to 220 tons, the GL1 Series provides the forming control of a link‑motion press with the speed, rigidity, and reliability expected from Stamtec’s gap‑frame platform.
Link‑motion technology modifies the slide velocity profile so the slide slows down significantly—up to 40%—during the working portion of the stroke. This slower forming speed allows the material to flow more effectively, reduces shock and snap‑through, and minimizes punch penetration forces. Meanwhile, the non‑working portion of the stroke accelerates to maintain high production rates.
The result is a press that delivers the following:
The defining feature of the GL1 Series, link‑motion technology improves forming control, reduces shock loads, and enhances part consistency—especially in deeper or more complex forming operations.
A wet clutch and brake system provides strong torque at lower air pressure, reduces lining wear, and dissipates heat efficiently for long service life and stable high‑speed operation.
A fast‑acting overload system instantly relieves excess tonnage to protect the press and tooling. Resetting is simple and quick, minimizing downtime.
The one‑piece welded steel frame resists deflection and maintains slide alignment under load, ensuring consistent part accuracy and extended die life.
Long, precision‑machined gibs guide the slide throughout the stroke, maintaining alignment even under off‑center loading.
Standard presses include a touchscreen control system with programmable setup, diagnostics, and safety functions. Controls from major brands—including Wintriss, Link, Allen‑Bradley, Siemens, and Mitsubishi—are available.
