Applications


The CTR8N is widely used in:

  • Automotive manufacturing (for bolts, studs, and suspension components)

  • Heavy machinery production (shafts, connectors)

  • Construction hardware (threaded rods, anchors)

  • Fastener manufacturing plants for high-volume output

Its robust design and cold-forming capability make it especially suitable for applications requiring:

  • High tensile strength

  • Excellent thread geometry

  • Minimal material loss and energy consumption



Key Features

✅ Moving Die Configuration

In this machine, the moving die setup means that one of the two thread rolling dies is in motion while the other remains fixed. This dynamic configuration:

  • Enables precise control over thread forming

  • Allows for better adaptation to different diameters and thread profiles

  • Ensures consistent pressure application across the workpiece

✅ Thread Length Capacity – 50 mm

The machine is engineered to roll external threads with a maximum length of 50 mm, making it ideal for:

  • Bolts and screws

  • Shafts with threaded ends

  • Custom fasteners requiring accurate and durable threading

This length ensures compatibility with a wide range of standard and custom parts used in automotive, machinery, and construction industries.
