Proc\u00e9d\u00e9s de moulage applicables pour le poly\u00e9therimide (PEI)<\/h2>\n

La haute r\u00e9sistance thermique et la sensibilit\u00e9 au cisaillement du PEI n\u00e9cessitent des configurations de moulage sp\u00e9cialis\u00e9es et des param\u00e8tres de pr\u00e9cision :<\/p>\n\n\n\n\n\n\n\n

Moulage par injection standard<\/td>\nExcellent. Configur\u00e9 avec des cylindres r\u00e9sistants \u00e0 l'usure sp\u00e9cialis\u00e9s pour mouler des plateaux de st\u00e9rilisation m\u00e9dicaux, des conduits d'avion et des composants de micro-ondes.<\/td>\n<\/tr>\n
Moulage \u00e0 paroi mince<\/td>\nBon. Tr\u00e8s adapt\u00e9 aux bo\u00eetiers de bornes \u00e9lectriques structurels et aux connecteurs de circuits imprim\u00e9s avec des chemins complexes.<\/td>\n<\/tr>\n
Moulage par insertion<\/td>\nExcellent. Le faible retrait stable du PEI en fait le substrat parfait pour encapsuler des filetages m\u00e9talliques et des connecteurs en laiton sans fissuration autour de l'insert.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/section>\n

Guide d'outillage et de fabrication du poly\u00e9therimide (PEI\/Ultem)<\/h2>\n

Le PEI est amorphe mais poss\u00e8de une viscosit\u00e9 de fusion extr\u00eamement \u00e9lev\u00e9e et est tr\u00e8s sensible \u00e0 la d\u00e9gradation par cisaillement. Un contr\u00f4le rigoureux du processus est obligatoire :<\/p>\n

    \n
  • Pr\u00e9-s\u00e9chage :<\/strong> PEI is highly hygroscopic. Extruding wet resin will cause severe hydrolytic degradation, turning parts brittle and causing aesthetic splay. We dry raw resin in desiccant hopper dryers at 150\u00b0C (302\u00b0F) for 4 hours to keep moisture below 0.02%.<\/li>\n
  • High Melt Temperature:<\/strong> Melting requires specialized machines with high-temperature capabilities. Melting points are strictly controlled between 340\u00b0C and 400\u00b0C (644\u00b0F to 752\u00b0F).<\/li>\n
  • High Mold Temperature:<\/strong> Pressurized oil heaters are utilized to maintain mold temperatures at 140\u00b0C\u2013180\u00b0C (284\u00b0F to 356\u00b0F). Proper mold temperature is vital to minimize molded-in stress, optimize surface gloss, and prevent stress cracking.<\/li>\n
  • Gate and Runner Design:<\/strong> To prevent high shear heating and aesthetic “blush” defects, we design oversized gates and rounded runners. Tool paths are calculated precisely during our DFM stage.<\/li>\n
  • Retrait faible pr\u00e9visible :<\/strong> As an amorphous material, PEI exhibits extremely low and uniform shrinkage (0.2% to 0.7%), supporting high-precision tolerances on multi-cavity tools.<\/li>\n<\/ul>\n<\/section>\n
