Spinneret microhole processing, super precision ultrasonic handle to deal with 4 major pain points

Molten spray cloth is known as the "heart" of the mask!



So why is a spinneret called the heart of the heart?



Because the production of melting and spraying cloth is formed by jet from the spinneret with the help of high-speed hot gas flow: the viscous flow of polymer melts is transformed into a fine flow with a specific section through the microholes and solidified by the solidifying medium.

Therefore, the spinneret is the core of the production line of melting and spraying cloth, the quality of melting and spraying cloth is closely related to the uniformity and stability of the spinneret, and has a high requirement for its microporous processing!

However on the stainless steel material, processing only 2-3 pores of the human hair thickness, and it is more (0.1 0.3 mm, aperture Φ spacing of less than 1 mm), difficulty cans be imagined!
