PA6 Powder Sintering
ظاهرة المشكلة
PA6 powder laser sintered parts have lower strength than injection molded parts and a rough surface
تحليل الأسباب
SLS sintering is a particle fusion process with lower density than '2079851475616104452; powder particle size distribution and preheating temperature affect fusion quality, and semi-molten particles remain on the surface; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
الحل
Optimize the preheating temperature close to the melting point, laser energy density, and layer thickness; mix new and used powder in proportion; post-process by sandblasting or vibratory finishing to improve the surface; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
الخلاصة الأساسية
SLS part performance relies on process parameter and powder management optimization, and post-processing improves appearance; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
