Consulting for lens cleaning systems by ultrasonics

Consulting and ultrasonic cleaning

The ATCP has provided consulting for a multinational industry located at the Manaus Free Trade Zone with the objective of increasing the service lifespan and reducing maintenance costs of ultrasonic cleaning systems. In that case, the ultrasonic cleaning systems are used in manufacturing spectacle lenses, one of the major elements of the production line.

The consulting service consisted in discussing the critical points of ultrasonic cleaning, and training maintenance personnel in predictive, preventive and corrective maintenance procedures. The results were very positive and are already saving time and resources for the client.

TRZ® in the mattresses industry

TRZ<sup>®</sup> Mattresses Industry

ATCP has provided a TRZ® Analyzer for a major manufacturer of mattresses and pocket springs. In that case, TRZ® Analyzer will be used in predictive, corrective and preventive maintenance of ultrasonic welding systems employed in machines that manufacture and package the springs.

Sometimes during the manufacturing process, the spring escapes out of the "pocket" and is pressed by the ultrasonic system at the time of welding, which kneads and damages the face of the sonotrode. This damage alters the operating frequency of the equipment and must be corrected.

The TRZ® Analyzer will be also used to recover transducers and to manufacture new sonotrodes, as well as to perform preventive maintenance.

Pocket springs manufacturers face serious problems with the reproducibility and reliability of ultrasonic welding systems of the machines to manufacture and pack the springs. In this context, TRZ® Analyzer is valuable piece of equipment because it provides greater control and understanding about the state of ultrasonic welding systems.

Piezoelectric damping of vibrations for cars

Sonelastic piezoelectric damping

ATCP has provided specialized services for the automotive industry with a view to damping vibrations in cars using tuned piezoelectric elements. The services consisted in dimensioning and fixing piezoelectric elements, besides calculating and developing synthetic inductors for high inductances (> 1 Henry). Obs.: synthetic inductors are electric circuits.

The position for fixing the piezoelectric elements was determined by the customer as a function of vibration modes they wanted to mitigate and through simulation by the finite element (FEM). The simulations were refined with the characterization of the modules of elasticity (Young's modulus, shear and Poisson's ratio) of the materials involved by using the Sonelastic® Solutions.

The damping provided by the piezoelectric elements was characterized by modal analysis and was superior to that obtained with only passive elements.
