What should I do if the melt blown machine mold (spinneret) is blocked? How to remove plastic?

The melt blown machine mold (spinneret) is not disposable. After use, it can be disassembled and reused through the following steps:

1. By vacuum calcination, the plastic debris inside the mold holes is preliminarily cleaned off;

2. Check if the meltblown fabric mold is broken, as some molds are made of poor materials and may break after calcination, leading to their disposal;

3. If the mold does not break after vacuum calcination, check if there are any other blockages in the small holes of the mold. If there are, first pass them through;
4. Use ultrasonic cleaning;
5. Use abrasive flow process for polishing;

6. After polishing, clean again and check the small holes in the mold;
7. If there are no other issues, this mold can be used again!

Cleaning method for removing plastic from meltblown fabric spinneret

Firstly, clean the ultrasonic stainless steel tank thoroughly, and thenvacuum calcinationPut the good spinneret into the slot and add clean water. The water level should be no more than two centimeters above the spinneret. Then add about 20 grams of rust remover and cleaning agent, and turn on ultrasonic waves to start vibration wave cleaning.
After cleaning for 30 minutes, adjust the position of each spinneret and the front and back of the spinneret.
3. Ultrasonic cleaning usually takes 60-90 minutes to clean thoroughly. The cleanliness of the water in the tank and the position of the spinneret cleaned by ultrasonic vibration waves are the main reasons for the cleaning. Therefore, maintaining the cleanliness of the water and frequently changing the position of the spinneret are the key factors.
4. After ultrasonic cleaning, the spinneret should be promptly removed from the water to blow dry the moisture on the surface and in the micropores.
5. After cleaning the spinneret, it should be promptly assembled and placed in a clean and dry place or in the spinning body to prevent moisture and external dust
