Heavy-Duty Advanced Series

Large Hydraulic Thread Rolling Machines for Heavy Industrial Applications

The PMC Heavy-Duty Advanced Series consists of large-capacity hydraulic thread rolling machines designed for heavy industrial thread and profile rolling applications.

These heavy duty thread rolling machines are engineered for forming threads on large-diameter bars and high-strength materials used in infrastructure, energy, and structural engineering industries.

Designed for cold thread rolling of large components, the machines provide the structural rigidity, rolling force, and process stability required for manufacturing heavy-duty parts such as foundation bolts, anchor bolts, tie rods, and structural fasteners.

Engineered for Heavy-Duty Thread & Profile Rolling

The Heavy-Duty Advanced Series is developed for large-scale thread rolling and profile rolling operations where high forming pressure and machine stability are critical.

With reinforced machine construction and optimized torque transmission, these industrial thread rolling machines maintain stable rolling pressure during production.

This stability helps manufacturers achieve consistent thread quality when processing large workpieces and high-strength materials.

Typical applications include:

• Foundation bolts for wind energy structures
• Tunnel construction anchor bolts
• Heavy tie rods and structural fasteners
• Marine and shipyard components
• Large threaded bars used in infrastructure and power plant construction

The machines utilize cold thread rolling technology, which improves material strength and surface finish compared with conventional cutting methods.

Rigid Machine Structure for Heavy Industrial Production

A key feature of the Heavy-Duty Advanced Series is PMC’s Movable Front Spindle Housing Mechanism, designed to enhance machine rigidity during high-force thread rolling operations.

This mechanism helps:

• Increase overall machine strength
• Reduce spindle deflection under heavy rolling loads
• Protect die spindles during high-pressure forming processes

By minimizing mechanical deflection, the machine maintains stable thread forming conditions when rolling large-diameter bars and high-tensile materials.

High-Capacity Thread Rolling for Large Components

The PM-250VS (160 Ton) Heavy Duty Thread Rolling Machine is designed for demanding large-scale thread rolling applications.

Typical production examples include:

• Wind energy foundation bolts
• Large structural anchor bolts
• High-strength stainless steel fasteners
• Titanium bolts for specialized engineering applications
• Heavy construction fasteners used in bridges and offshore structures

The machine can process high-tensile bars up to 9 meters in length and 200 mm in diameter, with thread lengths of up to 600 mm on each end.

To support stable rolling of long workpieces, an auxiliary synchronization motor (2 HP) assists bar rotation during the thread rolling process, helping maintain smooth and controlled forming.

Specialized Thread & Profile Rolling Capabilities

The PMC Heavy-Duty Advanced Series supports a variety of specialized thread and profile rolling applications, including:

• Trapezoidal threads (TR)
• DIN 405 knuckle threads
• Heavy spline rolling
• Ball screw profiles
• Large tie rod threads
• Infrastructure foundation bolt threads

These machines are designed for manufacturers requiring high-capacity thread rolling equipment for heavy industrial production.

Designed for Infrastructure and Energy Industry Manufacturing

As a Taiwan-based thread rolling machine manufacturer, PMC focuses on machine rigidity, stable forming pressure, and reliable industrial performance.

The Heavy-Duty Advanced Series hydraulic thread rolling machines are designed to support manufacturers involved in large-scale infrastructure, renewable energy, marine engineering, and heavy mechanical production.

These machines provide durable machine construction and stable cold thread rolling performance for demanding industrial applications.
