FAQ about high speed thread rolling machine:

How to select the suitable thread rolling die for thread rolling machine?

When selecting the mould for nail threading machine,there are 3 parameters to consider:

  1. The welding point (reserved  position for the welding wire)
  2. The diameter of the nail
  3. The shape of the texture (ring or screw shank).

Concerning the reserved  position for the welding wire: the position where the nail is not rolled or threaded.

  • For Nail Length 25-38mm,the standard is 8-19mm
  • For Nail Length 45-100mm, the standard is 19-37 mm.

Nail diameter: plus or minus 10% of the applicable range, for example, the mold of 2.1mm can also be used for 2.0 and 2.2mm.

The shape of the texture:

  1. Commonly used screw thread (also known as twist pattern) has a certain angle, usually 25 degrees.
  2. Ring pattern, ring after ring, the parameter is the distance between the two rings.

Commonly used models:

Thread 8-19 welding position, wire diameter 2.0 (make 25-38 long nails with 1.9-2.1 diameter)

Thread 19-37 welding position, wire diameter 2.3 (make 45-100 long nails with 2.1-2.5 diameter)

Thread 19-37 welding position, wire diameter 2.8 (make 45-100 long nails with 2.5-3.1 diameter)
