 2. The plastic should not be put into the melt cylinder before it reaches the dry level, because it is easy to be stuck in the rod groove of the feeding section with strong water, forming a difficult phenomenon of feeding.
3. Pri oblikovanju se zlahka ohladi na injekcijski šobi. Če se tlak vbrizgavanja med hlajenjem poveča, je mogoče zlahka zlomiti povratni ventil, zato mora biti nadzor temperature na vbrizgalni šobi ustrezen. Da bi preprečili prelivanje plastike v kalup, je priporočljivo uporabiti nadzorovano šobo.
4. When changing to other plastics for injection, it should be noted that the original nylon heating temperature is 270 degree or more, while the general material heating temperature is only about 200 degree for operation, so the melting barrel must be heated to the nylon heating temperature before operation, otherwise it is easy to break the screw's check valve and dispensing head.

PE
1. PE material visoke gostote ima očitno temperaturo kristalizacije, zato je bolje povečati hitrost vbrizgavanja. 2. 2. Pri debelih mesnih izdelkih je še posebej pomembno povečati hitrost vbrizgavanja: lahko izboljša površinski sijaj izdelkov, prepreči deformacijo, zmanjša krčenje pri oblikovanju itd. 3. 3. Zasnova vijakov in ne{{ 5}}oprema za vzvratno vožnjo mora biti natančna, če pride do izgube ali poškodbe, se material dodaja počasi. (Zaradi povratnega toka plastike se količina vbrizgavanja v kalup zmanjša, staljeni material pa se podpre v dozirnem delu, tako da se nov material v dovodnem delu zadrži, kar povzroči odpoved presnove in tako nastane oblikovani izdelki z nesolidno kakovostjo, močnim krčenjem in visoko stopnjo napak.) 4. Oblika kalupa (vrata, tekač) ima hitro hitrost dokončanja materiala. 5. Sprejmite način hlajenja z enakomerno hitrostjo hlajenja. 6. 6. Uporaba vijačnega stroja za oblikovanje je boljša, dobra pretočnost; ni potrebe po visokotlačnem tlaku vbrizgavanja, zadrževalni tlak mora biti daljši 3060 odstotkov. 7. Stopnja krčenja je 2,5 odstotka in 2,0 odstotka v pravi kotni smeri. 8. Oblikovani izdelki morajo biti zasnovani tako, da preprečujejo upogibanje in deformacije. 9. Nizka
