PA12 Warpage Deformation Control
Sorun Belirtisi
【Problem phenomenon】PA12 flat plates and frame parts warped, with poor assembly fit
Neden Analizi
Uneven product cooling, uneven wall thickness, over-filling, and excessively fast injection speed are the four major inducements of warpage; uneven internal stress distribution is released and deforms after demolding; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
Adjust mold temperature control to make cooling uniform; homogenize wall thickness in product design; reduce injection and holding pressure to prevent over-filling; reduce injection speed; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
For warpage, first check cooling and wall thickness uniformity, then reduce pressure and speed to reduce internal stress; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
