History

In April 1982, four entrepreneurs founded MARCO Systemanalyse und Entwicklung GmbH.

A new chapter began in 1992 with the integration of TRIDELTA's piezo ceramic development department in Hermsdorf. Hermsdorf had been a center for technical porcelain and ceramics since the 19th century, and later also for piezo ceramics - an ideal environment for this further development.

In August 1992, marco integrated the piezo material development and application technology department. This step was technologically decisive: it marked the beginning of the development of marco Piezotechnologie, which turned the pure purchase of piezo disks into an in-house piezo ceramic and product development and production department.

Piezo stacks show problems with durability, so the Torque Block® is developed. With its further development and the granting of a patent in 1998 (DE 196 46 511), marco lays the foundation for the success of its dispensing valves. Based on this invention, a complete dispensing system was developed over the years that covers the entire process - from the dispensing valvewith a suitable insert, material preparation and storage, feeding, precise application and integration into the production line with the marco Gantry Systems series.

After decades of development work, the breakthrough came in 2012: marco successfully established itself as a specialist for piezo in sensors, actuators and components. This turned the long years of development into a sustainable success story.

Today, marco impresses with an impressive variety of piezoceramic solutions. The portfolio of marco piezo technology ranges from applications in medical technology to solar panels for satellites and impressively demonstrates the versatility of the technology:

• Torque Block® is the drive of the marco high-precision dosing valve
• The marco bubble sensor detects air bubbles in liquids with a flow diameter of less than 100 µm
• Ultrasonic parking sensor for a premium German car brand
• Sensors for detecting aquaplaning under the name SHAKE
• Structure-borne sound sensors for detecting material fatigue, e.g. in wind generators

• FPM 110 is a hard piezoelectric material with a narrow hysteresis and very high mechanical quality. Particularly noteworthy is the exceptionally high piezoelectric charge constant for hard materials. It is designed for the power ultrasonic range, but is also used in sensors in multilayer technology.
• FPM 231 is a soft material with very high deformation (S₃ = 0.19 % at 2 kV/mm), low mechanical properties and a high relative dielectric constant. Its outstanding piezoelectric charge constant makes it the ideal material for actuators, especially for Torque Block® applications, bending actuators and multilayer stacks.
• FPM 202 is a piezoelectrically soft material with high electromechanical coupling factors and a low relative dielectric constant. It has a high charge and pressure constant and can also be used in the extended temperature range thanks to its high Curie temperature. Typical applications are Air ultrasonic transducers, modular transducers as well as force and acceleration sensors.
• Despite its high Curie temperature and low dielectric constant, FPM 203 has a very high deformation (S₃ = 0.18 % at 2 kV/mm). It can therefore be used for actuators that operate in the higher temperature range. This material is ideal for Torque Block® applications, but - similar to FPM 202 - it can also be used in ultrasonic applications.
• FPM 240 is a material that was specifically developed for bending actuators. Due to a higher planar coupling factor and a lower x-y linkage of the stiffness tensors, greater deflections and forces can be achieved than with the similar material FPM 231.

marco is a medium-sized family business in which several families are involved. Successfully active on the world market, development and production are exclusively in Germany. Thanks to our interdisciplinary team and innovative solutions, we set standards worldwide. Piezo ceramics from marco prove their strength particularly in the field of complete dispensing systems - whether for dispensing solder pastes, applying silicone lensesor solar cells for space.

Precision and reliability result from the interaction of system analysis, development and marco piezo technology.
