Types of Manual Press

At A-Tech Instruments Ltd., we offer two primary types of manual presses: toggle presses and rack and pinion presses. Each type is designed to meet specific operational needs, ensuring that all aspects of your pressing requirements are covered with precision and efficiency.

Toggle Presses

Toggle presses are known for their ability to deliver high force at the end of the stroke, making them ideal for applications that require a significant final force to secure components. This feature is particularly useful for tasks such as riveting, crimping, and joining operations where the peak force is critical at the stroke’s completion. The mechanical advantage of a toggle press increases as it reaches the end of its cycle, providing maximum force with minimal effort from the operator


Rack and Pinion Presses

Rack and pinion presses offer a consistent force throughout the stroke, which is perfect for applications requiring uniform pressure for assembly operations. This type of press operates with a straightforward mechanism where the rotation of a pinion moves a rack to apply force directly and evenly. Ideal for pressing, bending, and forming operations, rack and pinion presses provide excellent control and repeatability, ensuring that each operation can be conducted with consistent pressure from start to finish.

Streamlined Data Acquisition

Our Press Monitoring Solutions feature built-in signal conditioning, also known as amplification, essential for accurately processing data from a range of sensors. These systems are compatible with Strain Gauges, Piezoelectric Force Sensors, Potentiometers, Voltage Output Sensors, SSI Serial, and Encoders, offering the adaptability required for various manufacturing applications.

Equipped with a 16-bit resolution and capable of high accuracy, our monitoring systems can perform scans at speeds up to 20 kHz. This level of detail is particularly crucial in high-demand settings like stamping presses, where precise and timely data collection is key to maintaining quality and efficiency.

Active measurements are triggered by changes in displacement or load levels, leading to synchronized X&Y pair measurements. This process not only captures comprehensive data about each press operation but also enables real-time monitoring and adjustments. Switch Points, which are critical real-time signals within the system, alert the Programmable Logic Controller (PLC) if measurements exceed or fall below-established thresholds. This immediate feedback allows for swift corrections, ensuring each press operation is executed with optimal accuracy and consistency.

Advanced Evaluation Techniques

After data acquisition, our press monitoring systems move to the crucial evaluation phase. This step is vital for ensuring each press operation meets quality standards. The system analyzes measurement curves, categorizing parts as GOOD (OK) or BAD (NOK) based on predefined criteria. Results are immediately sent to the Programmable Logic Controller (PLC) for real-time feedback, allowing for prompt corrective actions when needed.

Because no two press operations are exactly alike, our systems are designed to adapt to slight variations while still meeting quality specifications. This flexibility helps maintain high standards without unnecessarily rejecting good parts, optimizing both efficiency and accuracy.

In addition to the traditional evaluation windows or boxes with defined entry and exit sides, DIGIFORCE® controllers also offer thresholds, trapezoidal windows with both X or Y alignment and tolerance envelopes. These elements include calculated values for local maximums and minimums, area under the curve, bending points, etc., which can then be combined with mathematical operations for greater analysis flexibility.

Traditional Windows

This feature ensures that the measurement curve enters and exits through specific predefined sides of a rectangular window. Operators can set these windows to allow one or multiple entries and exits. If the curve deviates from the rules, the system instantly updates the PLC, providing immediate feedback to maintain continuous quality control.

Trapezoidal Windows

These windows set evaluation criteria along sloped portions of the measurement curve. This capability is particularly useful for applications where force dynamics change progressively, such as forming or bending operations. They facilitate easy criteria generation for sloped segments, providing greater flexibility in assessing complex operations.

Dynamic Thresholds

These serve as essential checkpoints in the evaluation process, establishing minimum and maximum bounds that the measurement curve must pass through. This ensures that every press operation meets precise force requirements, preventing both under-pressing and over-pressing. Dynamic thresholds are crucial for maintaining the quality and durability of the assembled parts.

Tolerance Envelopes

This feature allows operators to set custom tolerance ranges on the DIGIFORCE® controllers. By sampling a distribution of press force curves, operators can define a tolerance envelope that specifies allowable deviations from the sample curve. This is particularly important for applications requiring high precision, as it accommodates both tight and loose fits, ensuring that parts are produced consistently within quality specifications.

Automated Data Collection

Our press monitoring solutions include advanced software that not only configures sensor calibration and triggering but also excels in data collection. This comprehensive software provides a full-featured display of measurement curves and is compatible with any Windows-based PC. It can store information from multiple presses, complete with part tracking and timestamps, facilitating easy access and management of collected data. The software also supports program backup and data retrieval, ensuring that all evaluation results and statistics are readily available for analysis and review.

Simple Report Generation

The data review wizard in our software simplifies the process of searching through historical data. Users can filter data by station, part number, serial number, date, time, and OK/NOK results, making it easy to locate specific information. This feature allows for efficient data review and report generation, with output options available in both Excel and PDF formats. This capability ensures that you can generate detailed reports quickly, aiding in quality control and process optimization. These features enhance the usability and effectiveness of our press monitoring systems, providing you with the tools needed to maintain high-quality production standards and improve operational efficiency.

Ensures accurate positioning of the tool in rack and pinion presses. It allows the press stroke length to be adjusted to an accuracy of 0.01 mm, making it perfect for high-precision assembly work.

Table Bore (TB)

Enables quick and accurate tool changes. By mounting the bottom part of the tool in the centric table bore and securing it with a transverse screw, setup times are reduced significantly. The alignment accuracy between the ram bore and table bore is less than 0.05 mm, ensuring consistent precision.

Stroke Counter (Z)

A five-digit stroke counter provides a rapid overview of the number of items produced. This counter can be reset, allowing operators to track production counts easily and ensure accurate output records.

Return Travel Lock (HS)

Prevents incomplete operations by blocking the return stroke during the downward motion. This ensures that forming, assembly, and joining operations are fully completed before the lever can return. The Quick-Release mechanism allows for easy removal of jammed parts at any position and resets automatically.

Two-Hand Safeguard for Manual Toggle Presses (H2H)

Enhances safety, especially in mass production or when used by disabled employees. The two-hand safeguard prevents reaching into the ram movement, requiring both hands to be out of the danger zone to operate the press. If activated during the stroke, the press blocks downward movement and can be reset to its starting position.

ERGO-Hand Lever

Improves ergonomics with a horizontal and rotatable hand lever, allowing for easier operation of the press without fully grasping it. This feature increases user comfort and ease of use.


Provides a stable foundation for the press, preventing tilting. Rubber stoppers prevent slipping, and movable threaded inserts adjust to fit the distance between the fixing holes of the press.
