What is the application of the piezoelectric stack actuator?

  • Cavity tuning
  • Hardness testing
  • Micro EDM
  • Cell penetration
  • Shock absorption and vibration reduction

What is the exactly piezoelectric actuator?

The piezoelectric actuator is a kind of device. Which converts electrical energy into a mechanical displacement or stress based on a piezoelectric effect.

The piezo stack (PZT stack) will be installed in the actuator.Piezo stack also called multilayer piezoelectric ceramic actuator, piezo actuator, piezoelectric stack actuator.

It’s a kind of industry ceramic with a very complex process. In He-Shuai Ltd, we used tape casting technology to produce the piezoelectric ceramic.

“Multilayer”  it means lots of piezoelectric ceramic disc. We can do some of the shapes for you. Like: disc, ring, cylinder, square with hole, and so on.

You can check our product list for standard models before you buy piezoelectric stacks. Or you can send us your requests for OEM orders.

How to install the piezo actuators?

The material of the product is ceramic material and has brittleness. So, the installation method should be surface contact. Do not use point contact or line contact. When using this product, the output direction and the axial direction of the device must be consistent. Click here for the installation pictures.

What’s the feature of the piezo stack?

  • Small size, Sub-nanometer resolution
  • Low voltage drive
  • Large displacements
  • Discrete stack
  • High dynamic drives
  • High output up to 50000N
  • Resistance magnetic
  • Can work in the vacuum environment

How to buy the piezo stack from China?

Here we have normal standards for your reference.If you haven’t find the size what you need, please contact us directly, we will reply to you very soon.

Note: The pre-tightening force of the installation generally does not exceed 20% of the output.

[1] The ceramic size does not include the size of the resin. The gray resin has a thickness of 50 μm on one side, the green side has a thickness of 0.5 mm on one side, and the size of the outlet is +1 mm on one side with a tolerance of ±0.2 mm.
The height tolerance is +/-0.05mm.
[2] PT150V series nominal displacement is the displacement stroke at 0~150V driving voltage, the maximum displacement is the displacement stroke at -20V~150V driving voltage, for reliable long-term
Use, it is recommended that the driving voltage be 0~120V. The maximum displacement of the PT200V series is the displacement stroke at 0~200V drive voltage.

What is the tape casting process for the piezoelectric stack?

The tape casting process of polycrystalline materials is very widely. It used for the production of single or multilayered piezoelectric materials. These materials are ideal for micro-actuator applications.

He-Shuai company offers this production capability in addition to press processing to meet the diverse needs of our customers.
