Inyeksion kalıplama turli xil polimer materiallarni qayta ishlashning keng tarqalgan usuli bo'lib, plastik zargarlik buyumlari, o'yinchoqlar, avtoulov qismlari, shishalar, konteynerlar va uyali telefon g'iloflarigacha. Ushbu qayta ishlash usuli hayotning barcha jabhalarida qo'llaniladi. Keng miqyosli hujayra madaniyatida ishlatiladigan hujayra fabrikasi, shuningdek, quyish jarayoni tomonidan ishlab chiqariladi.
Inyeksion kalıplama jarayoni plastmassani isitish, plastiklashtirish va eritish uchun qarshi kalıplama mashinasidan foydalanish va keyin uni qoliplash uchun qolipning bo'shlig'iga AOK qiling. Sovutgandan so'ng, eritma qotib qoladi va keyin qolipdan chiqariladi. Ushbu qayta ishlash usuli quyidagi afzalliklarga ega:
1. Bu murakkab nozik mahsulotlarni ishlab chiqarish uchun javob beradi. Inyeksion kalıplama jarayoni murakkab plastik nozik qismlar va agregatlarni osongina loyihalashi mumkin. Boshqa texnikalar bilan taqqoslaganda, inyeksion kalıplama juda kichik toleranslarga ega xususiyatlarni topadi.
2. Chiqindilarni kamaytiring: in'ektsiya yo'li bilan qilingan barcha parizonlarni puflash qolipiga puflash mumkin va ishlov berish jarayonida hech qanday chiqindilar hosil bo'lmaydi, bu esa qoliplash materiallarining chiqindilarini kamaytiradi.
3. Tayyor mahsulot sifati yaxshi: silliq yuzasiga ega bo'lgan hujayra zavodi tirnalgan holda olinishi mumkin.
4. Yuqori darajadagi avtomatlashtirish: Ko'pgina inyeksion kalıplama jarayonlari mashinalar va robotlar yordamida amalga oshiriladi. Avtomatlashtirish ishlab chiqarish xarajatlarini kamaytirganidek, qo'shimcha xarajatlar ham kamayadi. Ko'p rejimli ishlab chiqarish, yuqori ishlab chiqarish samaradorligi.
Yuqoridagilar hujayra zavodining inyeksion kalıplama jarayonining to'rtta asosiy afzalliklaridir. Ko'p qatlamli tuzilish tufayli, har bir qatlam ishlab chiqarilgandan so'ng, mahsulotning to'liq to'plamini yaratish uchun qatlamlarni birlashtirish uchun maxsus payvandlash yoki yopishtirish jarayonidan o'tishi kerak.
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.
