lom vijka stroja za injekcijsko prešanje

The vijak temperatura loma također je povezana, ali je rijetko, gotovo sav sam vijak je slabe žilavosti, ili je vijak korišten dulje vrijeme, obnoviti vijak!

The brizganje materijala su grubi. Na primjer, dodavanje GF [staklena vlakna] od materijala za injekcijsko prešanje je najskuplji vijak i stroj! Ovaj materijal za injekcijsko prešanje ima slabu fluidnost i zahtijeva veliku brzinu paljenja! Ako ne svladate dobro, upaljač ima raketnu glavu i prekid inverznog prstena, a teški razbija vijak u čvorove! Lom vijka se može spriječiti. Pri korištenju sirovina dodati GF, ako je stroj zaustavljen dulje od 3 minutama, potrebno je očistiti sirovine u bačvi kada je stroj uključen. Najbolje je koristiti PP s većom viskoznošću za čišćenje vijka kako bi se spriječilo raspadanje sirovina za injekcijsko prešanje za omotavanje vijka i glave rakete. .

Prilikom čišćenja, brzina vrtnje se smanjuje, tako da se materijali za injekcijsko prešanje potpuno rastale kada se zagrijavaju i okreću. The cleaning screw is the best for pin-point molds to prevent the glue channel from sticking to the static template. Use hot materials to start production!

When the work order is full, Stop ubrizgavanje mašina and complete the work, and the mass-produced product is enough. Stop the machine and clean the screw immediately, so that all the residual injection materials of the screw are discharged, and then use PP or clean the injection material of the screw.

Process problems, back pressure and screw breakage are also related! If the back pressure is too large, when feeding, the post-screw work force increases, which can also cause the screw to break! Do

The end point of the plastic injection cannot be zero, especially with a high-speed injection machine [accumulated gas] shooting can easily damage the rocket head! The projected residual volume should be controlled well. Remember, the most important thing is that the holding pressure time must be adjusted to zero after manual injection to prevent the end point of the injection from being zero!

The molding temperature must be controlled well. When starting up, pay attention to loosening and retreating before shooting, because when there is no loosening, there is a raw material package at the rocket head. If the material is washed or shot directly, it can directly cause the rocket head to break and the reverse ring to break. Remember to loosen it and then Shoot to separate the injection material of the rocket head from the rocket head! !

Remember that no matter what injection material is used, if the machine stops and does not produce, sav preostali materijal za injektiranje mora se ispustiti kako bi se pripremio za sljedeću proizvodnju!
