What Is SHF (Simple & High Performance Former) and How Does It Work in Metal Forging Processes
🌟 Key Takeaways
• SHF is a horizontal metal forging machine designed for high speed and stable mass production
• The horizontal structure enables output of up to approximately 3,000 parts per hour
• Ideal for high-strength, high-precision components in the automotive industry
• Supports one-piece forming, reducing secondary processes and total production cost
ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
Metal component manufacturing for automotive and machinery industries—such as gears, clutch hubs, or sleeves—requires both structural strength and dimensional accuracy. For this reason, metal forging processes are widely used instead of machining from solid bars, especially for applications that demand continuous high-volume production.
🔷 What Is SHF
SHF, or Simple & High Performance Former, is a horizontal hot forging machine (Horizontal Hot Forging). Unlike vertical forging machines, the hammering mechanism of SHF operates in a horizontal direction.
The core concept of SHF is to reduce resistance caused by the weight of workpieces and dies, allowing higher speed and improved process stability.
🔷 Operating Principle of SHF
The SHF process begins by feeding heated steel billets into the die set. The machine then performs continuous horizontal forging throughout the production cycle.
Key characteristics of the SHF mechanism include:
• Horizontal hammering eliminates the need to counteract gravity
• Uniform die lubrication reduces wear and extends die life
• Workpiece movement aligns with the forging force, improving forming stability
With this structure, SHF machines can operate at speeds of up to approximately 50 SPM, equivalent to about 3,000 parts per hour, while supporting a maximum forging force of up to 1,300 tons.
🔷 Differences Between SHF and Conventional Forging Machines
Compared with vertical forging machines, SHF offers clear advantages, particularly for mass production applications:
• Higher production speed due to reduced gravitational resistance
• Consistent motion control, resulting in stable product quality
• Efficient support for one-piece forming
These advantages help eliminate secondary operations such as finishing, leading to shorter lead times and lower overall manufacturing costs.
🔷 Suitable Products for SHF
SHF is suitable for components with diameters of approximately Φ60–Φ120 mm that require high strength, such as:
• Gears
• Clutch hubs
• Sleeves or hollow components
• Single-piece parts with steps or grooves
📘 Summary
SHF is a horizontal metal forging machine designed to deliver high speed, consistent quality, and stable production performance. It is particularly well suited for large-volume manufacturing of metal components in the automotive and machinery industries.
