What is a Piezoelectric Transducer? What is it used for?

A Piezoelectric Transducer is a device that converts mechanical energy, like pressure, into an electrical signal and can also perform the reverse, turning an electrical signal into mechanical motion.The latest mechanism is used for exemple in Ultrasonic Testing.The name comes from the Greek word “piezo”, which means… <a href="https://www.plastiform.info/en/blog/engineering/what-is-a-piezoelectric-transducer-what-is-it-used-for/" class="read-more">Read More</a>

What is Pneumatic Testing ? How Does it Work?

Pneumatic testing is a method used to check if a pressure system like a pipe, tank, can safely withstand the expected pressure.Instead of filling it with water, the system is pressurized with air or another safe gas. This helps reveal whether it is strong enough, free from leaks, and safe… <a href="https://www.plastiform.info/en/blog/quality-assurance/what-is-pneumatic-testing-how-does-it-work/" class="read-more">Read More</a>
