The length of the head of the head with cast iron sheep varies from 300 mm, 600 mm, 1.2 meters, 1.6 meters, or even more than 3 meters. 300 to a few.
The current Spinnerets drilling process is essentially the treatment of drilling and laser. has a very low lifespan. Therefore, these small holes must be polite before the use of the spinneret.
So what method can be used to polish these micropores? Of course, manual polishing is not realistic. A worker cannot launch a spinnerret per day. For porous polishing such as spinnerrets, the polishing method is generally used to grind the grinding of the abrasive grain flow.

Porous pores of polishing of the abrasive fluid: use mild abrasives (the abrasive particles are extremely fine and the abrasives are semi-frowned), and after extrusion, they enter the interior holes directly and then flow. This circulates several times and plays a role in polishing. The inner hole of the polished spinneret can obtain a mirror effect. Even if he is porous, he is polished at once.
Because there are a lot of small holes on the cast iron spinneret and the opening is small. Consequently, the polishing of spray plates blown by fusion requires the use of abrasive equipment with special fluid micropor and mild diamond abrasives with a smaller particle size.
Let’s take a look at the fluid polishing process diagram of the abrasive particles of the spinneret.
Currently, there are already many factories in China which can make heads of cast iron mussels, which is also the reason why ordinary masks can be easily purchased.
However, there are very few N95 masks on the market. Indeed, there are very few companies that can make heads of cast iron molds with a diameter of pores of 0.1-0.15 mm. The diameters of micropores of other heads of Mask Mussels are generally 0.2 to 0.3 mm, which seems to be a small difference, but the difficulty of treatment and the difficulty of polishing are enormous!
