On July 16, 2025, ATCP Physical Engineering proudly celebrates 25 years of dedication to the development and manufacture of instrumentation for power ultrasound and material characterization. Founded in 2000 as a spin-off from the Federal University of São Carlos (UFSCar) in Brazil, the company was initially established to manufacture piezoelectric ceramics. It quickly shifted its focus to the development of specialized instrumentation, where it has since built a strong reputation across both industrial and scientific sectors. Today, ATCP’s reach spans the globe through an established network of distributors and commercial partners.
Over the years, ATCP has developed testing instruments that have become benchmarks in industrial, academic, and medical applications. The TRZ Analyzer and SonicSniffer are now essential tools for maintaining and ensuring the quality of power ultrasonic equipment, such as ultrasonic welding machines and medical transducers. The Sonelastic system, developed in collaboration with UFSCar, has advanced the non-destructive testing of elastic moduli in materials such as concrete, composites, and wood.
Another standout innovation is PiezoClamping, a groundbreaking technology that enables real-time measurement of the prestress applied during the assembly of ultrasonic transducers. This innovation enhances both the performance and longevity of the equipment.
ATCP is also recognized for its contributions to technical standardization, actively participating in the development and revision of international and national standards. Notably, the company played a key role in ASTM E1876 and ABNT NBR 8522-2, both of which relate to the characterization of elastic properties in materials and concrete.
During the COVID-19 pandemic, ATCP made a particularly meaningful contribution by supplying instruments and technical training for the production of ultrasonic welding machines used in the manufacture of disposable face masks, a moment that highlighted how its technology could directly support global public health efforts.
Backed by a highly skilled and dedicated team, ATCP continues to pursue its mission of designing, producing, and delivering test and measurement solutions that address critical challenges faced by its customers. Looking to the future, the company reaffirms its commitment to creativity, quality, and integrity, values that have guided its journey from the very beginning. ATCP’s vision for the coming years is clear: to strengthen its position as a global reference in power ultrasonics and materials characterization.
