HFMI (High-Frequency Mechanical Impact)

The HFMI (High-Frequency Mechanical Impact) ultrasonic peening technology is an advanced mechanical treatment method designed to improve the fatigue strength and durability of metal structures. It is widely used in heavy industry, construction, energy, and machinery production, where reliability and material longevity are crucial.

How Does HFMI Work?

The HFMI process involves applying high-frequency mechanical impulses to the surface of a metal component. As a result:

• Residual stresses present on the surface of welds and their vicinity are reduced.
• A hardened layer forms on the material’s surface, increasing its resistance to cracking and fatigue.
• Weld durability is enhanced, which is especially critical for structures exposed to dynamic loads.

Using HFMI technology can increase the strength of metal components by up to 50-100% compared to traditional treatment methods.

Applications of HFMI

HFMI technology is primarily utilized in:

• Steel structures, such as bridges, wind towers, and cranes, where increased weld durability is vital for safety and reliability.
• Automotive industry, for strengthening the frames of heavy vehicles and agricultural machinery.
• Energy sector, for processing turbine components, pressure vessels, and pipelines.
• Machinery construction, where material fatigue resistance and durability are essential for device reliability.

Advantages of HFMI Technology

• Safety – Enhanced fatigue strength of metal components.
• Economy – Reduced operational costs through prolonged structure lifespan.
• Compliance with industry standards – HFMI meets the strength and quality requirements for demanding applications.
• Mobility – Compact HFMI devices can be used in workshops and on-site.
