When using the laser head, you will encounter the problem of nozzle clogging, which makes it impossible to use the laser head normally. Now let's investigate the general reasons for the blockage of the laser head nozzle?

1. Improper nozzle selection or poor maintenance

It is easy to cause nozzle contamination or damage, or due to poor roundness of the nozzle or partial blockage caused by hot metal splashing, vortexes will be formed in the nozzle, resulting in a significant deterioration in cutting performance. Sometimes, the nozzle opening and the focused beam are off-axis, forming the edge of the beam cutting nozzle, which will also affect the cutting edge quality, increasing the cutting edge width and displacing the cutting size.

2. The temperature is too low

If the nozzle temperature is low, it may be that the nozzle is in contact with the cold mold for a long time and loses heat during the fixed feeding, or the nozzle heating ring is insufficiently heated or has poor contact resulting in low material temperature, which may block the mold's feeding channel.

3. The inner hole of the nozzle is not suitable

If the nozzle is too small, due to the small flow diameter, the specific volume of the strip will increase, which will easily be cooled, block the feed channel or consume the injection pressure; if the nozzle is too large, the flow cross-sectional area will be large, and the unit area pressure of the plastic will be low. The formation of a small shooting force.

Four, do not clean for a long time

The nozzle is a part of the end of the laser head. It will accumulate ash layer without cleaning for a long time, and the slag will be in the nozzle mouth, which will cause blockage and the laser head cannot work normally.
