What Is a Double-Acting Ultra-Precision Press?
A double-acting ultra-precision press is a fully automatic, high-precision press system in which the pressing force can be applied in a controlled manner from both the top and the bottom (or from two different axes). Thanks to this structure, stresses generated on the part during pressing are balanced, material flow becomes more controlled, and dimensional accuracy reaches the highest level.

The main features of these press systems include:

• Bidirectional force application capability

• Micron-level positioning accuracy

• Closed-loop force and stroke control

• High repeatability

• Fully automatic and traceable production

DMR Tekno combines these features with advanced engineering solutions in its double-acting ultra-precision press systems.

DMR Tekno’s Double-Acting Press Approach

DMR Tekno adopts a process-oriented, custom-engineered approach in double-acting ultra-precision press projects. Each pressing application differs in force distribution, speed profile, die geometry, and production capacity. Therefore, instead of standard press solutions, systems are fully engineered according to the customer’s specific production process.

Core principles of DMR Tekno’s approach:

• Maximum force and position accuracy

• Stable, vibration-free mechanical structure

• Advanced sensor and control infrastructure

• Long-lasting and reliable design

• Easy integration and operation

This approach ensures safe and efficient use of double-acting ultra-precision presses across various industries.

Working Principle of a Double-Acting Press

In double-acting ultra-precision press systems, the pressing operation is performed through synchronized motion of two pressing actions. This principle offers major advantages, especially in the production of parts with complex geometries.

Basic operation steps:

1. Part Loading: The part or powder material is placed into the die manually or via automatic feeding systems.

2. Lower Pressing Motion: The lower table or piston moves according to predefined force and speed profiles.

3. Upper Pressing Motion: The upper press head engages synchronously with the lower movement.

4. Balanced Force Distribution: Bidirectional force ensures uniform material compaction.

5. Feedback and Control: Data from load cells and position sensors is evaluated in real time.

6. Unloading and Continuation: The pressed part is automatically discharged and the next cycle begins.

Compared to conventional single-acting presses, this structure delivers significantly more controlled and higher-quality results.

Ultra-Precision and Control Mechanisms

In double-acting ultra-precision presses, “ultra-precision” does not simply mean high force—it means precise control over when, where, and how much force is applied.

DMR Tekno’s ultra-precision concept includes:

• Real-time force measurement via load cells

• Micron-level position control using linear encoders

• Closed-loop control algorithms

• Digital filtering and data validation systems

This infrastructure ensures that every pressing cycle meets identical quality standards.

Mechanical Design and Structural Rigidity

Mechanical structure forms the foundation of pressing accuracy. Even minimal deflection or vibration can negatively affect tolerances.
