A few years ago, one of the world's largest auto parts manufacturers, with a strong presence in Brazil, imported a machine from Germany to perform shot peening on stabilizer bars.
The stabilizer bar, found in the front suspension of most vehicles and in the rear of some models, plays a crucial role in vehicle stability. This component connects the two sides of the suspension, limiting the vehicle's movement along its longitudinal axis. As the name suggests, the stabilizer bar is essential for maintaining balance and control, ensuring even weight distribution between the wheels. This is why the finishing on this material must be extremely precise.
The customer reached out to CMV® with a specific requirement: they needed to achieve a minimum Almen intensity of 0.45 A. Unfortunately, the eight-blast wheel machine they had imported was unable to meet this requirement, even when new.
Faced with this challenge, we undertook a comprehensive modernization of the shot peening equipment. One of the most significant upgrades was the installation of our blast wheels with curved blades.
These advanced blast wheels offer superior performance compared to conventional models. With a launch speed approximately 30% faster than most competitors, they deliver an impact force that is 70% greater. This upgrade alone made a substantial difference, but we didn’t stop there. We also overhauled the entire electrical and electronic control systems, including the installation of precise electromagnetic abrasive flow valves.
The results were outstanding. With our blast wheels operating at a maximum of 60Hz, we exceeded the customer’s expectations, achieving an Almen intensity of 0.6 A.
At CMV®, we bring extensive experience and cutting-edge technology to the field of shot peening, whether using compressed air or blast wheels. Contact our team of experts and rely on the solutions from a company with over 45 years of blasting experience.
