Why Choose Us
With 20+ years of expertise, Uranus has developed over 20 models and delivered hundreds of servo oscillation systems worldwide—trusted for innovation, reliability, and performance.

The mold oscillating servo cylinder enables the mold in the slab continuous casting production line to perform arc motion along the radius of the continuous casting machine. This motion is governed by specific amplitude, frequency, and waveform deflection characteristics, facilitating the mold’s up-and-down oscillation. The controlled sequential vibration ensures lubrication and prevents adhesion between the casting steel and the mold wall.

The Uranus mold oscillating cylinder utilizes electro-hydraulic direct drive technology, enabling both sinusoidal and non-sinusoidal vibration functions. This system offers several advantages, including intelligent operation, high frequency, high precision, low maintenance, a long service life, and high reliability. Its design is simple and cost- effective, with easy installation and low maintenance. The system enhances casting speed, increases the output of the casting machine, and reduces energy consumption as well as operating costs while improving both production efficiency and product quality.

For over 20 years, we have produced hundreds of mold oscillating cylinders in more than 20 different types. Below are several examples of our mold oscillating cylinders:
