Nargesa NF70 End Hot Wrought Iron Machine

The Nargesa NF70 End Hot Wrought Iron Machine is a versatile hot-forging machine designed to shape the ends and central sections of heated steel bar into a wide range of decorative profiles. Using interchangeable forming rollers, the NF70 can produce flat ends, pyramidal ends, striated and fishtail ends, decorative baluster centers and other custom ornamental profiles in round bar, square bar and flat bar.

Designed for ornamental ironwork, architectural metal fabrication and repetitive decorative production, the NF70 is well suited to manufacturers producing gates, fences, railings, balustrades, windows, doors, bed headboards, metal furniture and other wrought iron components.

The NF70 can process mild-steel round bar up to 20 mm (3/4"), square bar up to 20 × 20 mm (3/4 × 3/4"), and flat bar up to 40 × 10 mm (1-1/2 × 3/8"). Its 20 RPM working speed, digital display, programmable turns and adjustable back gauge give the operator control over the forming process while helping maintain consistency across repetitive production runs.

Unlike the Nargesa PC16, which is primarily designed to roll heated material into snail-shaped decorative ends, the NF70 uses different forming rollers to create a broader selection of ornamental shapes. Optional roller sets further expand the machine's capabilities, while Nargesa can manufacture custom rollers on request for specialized architectural designs and proprietary profiles.

Manufactured in Spain, the Nargesa NF70 is built for professional ornamental metalworking and complies with CE industrial machinery manufacturing standards.

Applications

The Nargesa NF70 is designed for ornamental and architectural metalworking where heated steel must be formed into consistent decorative ends, patterns or central details.

Typical applications include:

• Gates and entrance gates
• Fences
• Railings and balustrades
• Windows and doors
• Ornamental balusters
• Bed headboards
• Metal furniture
• Decorative panels
• Architectural ironwork
• Wrought iron components
• Ornamental forged ends
• Custom decorative steel profiles

Depending on the roller set installed, the NF70 can produce:

• Flat ends
• Pyramidal ends
• Striated ends
• Fishtail ends
• Decorative baluster centers
• Embossed ornamental patterns
• Custom profiles using specially manufactured rollers

The NF70 is particularly useful for fabricators that need to produce large quantities of matching ornamental components. Once the appropriate tooling, back-gauge position and machine settings have been established, the same operation can be repeated consistently across a production run.

For optimum results, the material must be heated to the appropriate forging temperature before being processed. Nargesa recommends its H1, H2 and H3 forging furnaces for heating material before forming.

Why Choose the Nargesa NF70?

The primary advantage of the NF70 is its versatility. By changing the forming rollers, one machine can produce multiple decorative profiles, reducing the need for separate machines dedicated to individual ornamental designs.

This makes the NF70 particularly valuable for ornamental metalworking businesses that produce a variety of gates, railings, balusters and architectural components. Standard tooling handles several common decorative ends, while optional and custom rollers allow the machine to be adapted to additional designs and specialized customer requirements.

The NF70 also provides a practical way to mechanize repetitive hot-forging work. Features such as the digital display, programmable turns and adjustable back gauge help operators establish repeatable settings, improving consistency between parts and reducing reliance on manual hand forging for high-volume production.

For shops producing ornamental steel components in quantity, the NF70 can produce thousands of parts during a working day under suitable production conditions. This helps increase output while maintaining consistent decorative profiles across larger production runs.
