je običajno uporabljen potrošni material v obsežni celični kulturi. Njegova struktura je sestavljena iz ene ali več plasti, zgornja plast pa je opremljena z dvema perfuzijskima priključkoma. Kateri postopek se uporablja za izdelavo tako zapletene strukture?Proces brizganja, ki ga je sprejela tovarna celic, v glavnem vključuje naslednje korake:cell factory
①Postopek pred ulivanjem:
Postopek predlivanja je ta, da se plastični material segreva, prevaža, stisne, striže, meša in homogenizira v sodu, da se material preoblikuje iz steklenega stanja v stanje viskozne tekočine, da se izpolnijo zahteve za brizganje.
②Postopek polnjenja z brizganjem:
V fazi polnjenja z brizganjem vijak vbrizga talino v skladiščni komori v votlino skozi šobo, vodilo kalupa in vrata pod potiskom injekcijskega cilindra.
③ Postopek stiskanja in stiskanja:
Nadaljujte z brizganjem, da zapolnite prostornino, ki jo del izprazni zaradi krčenja.
④Postopek hlajenja in strjevanja:
Po končanem zadrževalnem tlaku se vrata zamrznejo. Izdelek je podvržen obdobju hlajenja in strjevanja.
⑤ Postopek izmetanja in dviganja:
Po tem, ko je izdelek nekaj časa ohlajen, ima določeno togost in trdnost. Del se izvrže iz brizgalnega kalupa z izmetnim zatičem kalupa.
Polnilni priključek in glavni del zgornjega sloja tovarne celic sta integralno brizgana. Ta postopek lahko zagotovi, da ima izdelek boljšo tesnenje in dobro trdnost. Zgoraj je proizvodni proces tovarne celic. Poleg tega je postopek brizganja primeren tudi za predelavo poliolefina, poliamida, polioksimetilena, polikarbonata in drugih materialov.
The filling port and the main body of the top layer of the cell factory are integrally injection-molded. This process can ensure that the product has better sealing performance and good strength. The above is the production process of the cell factory. In addition, the injection molding process is also suitable for the processing of polyolefin, polyamide, polyoxymethylene, polycarbonate and other materials.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
