1. Adjust extruder parameters: Adjust extruder parameters such as temperature, pressure and speed according to the causes of particle generation to ensure the fluidity and stability of materials.

2. Improve mold design: improve mold design and manufacturing quality, reduce friction and wear, and reduce the generation of particles.

3. Post-treatment method: spray lubrication, vacuum and other methods can be used to remove the generated particles, and finally a product with good quality can be formed.
