Priyorite ajisteman vitès: Tanperati a gen yon inèrsye tèmik. Pandan pwodiksyon ki estab, tanperati a ta dwe ranje, epi vitès liy lan ta dwe sèvi kòm pi repons 'a tan'.
II.Defini Anviwònman Tan Sintering Efektif ak Zòn Tanperati
Sèvi ak 350°Castheeffectifintering limit: PTFEfonn nan anviwon 327°C,mennivelmandistriyèl mande370–395°C.Se poutèt sa,zòn ki pi wo a 350°Ci defini kòm efektif nan zòn entèr.
Distribisyon tanperati milti-zòn: Zòn prechofaj (100-250 ° C) - retire èd pwosesis yo epi anpeche anpoul ; Zòn Sintering ( 360 - 395 ° C ) - reyalize nivo fizyon ; Zòn anviwònman tanperati wo ( 380 - 390 ° C ) - soulaje estrès entèn ;

III.Specifikasyon Pwodui Detèmine Tan Sib ak Ajisteman
Referans Enteringtimes (nan 380-390 ° C): Kalite ki lejè (0.08–0.13mm)–30–60segonn;Kit estanda (0.18–0.25mm)–1.5–3minit;Kay ki lou (0.35mm anlè)–3–5 minit oswa pi long, ki nesesè pou anpeche 'kwit deyò, bò lari'.
Idantifikasyon ak ajisteman: Ensifizansintering (lowstrength, powdershedding, micro-cracks) → reducespeedtoextendtime; Over-sintering (jòn, brittleness, irritatingwhitefumes) → ogmante vitès pou diminye rezidans nan tanperati ki wo.
Tanperati-tanperasyon ekivalans: Entèrasyon wo-tanperati rapid (395-405 °C, plizyè douzèn segonn, gwo risk) oswa tanperati ki ba-enterasyon ki ba (360-375 °C, 5-8 minit, bon jan kalite ki pi estab) yo tou de posib.
