Nkhani Za Kampani

1. Chifukwa chiyani mankhwala opangidwa ndi jekeseni amakhala ndi ngodya yojambula?

Nthawi zambiri, zinthu zopangidwa ndi jekeseni ziyenera kukonzedwa kudzera mu nkhungu zofananira. Mankhwala opangidwa ndi jekeseni akapangidwa ndi kuchiritsidwa, amachotsedwa mu nkhungu kapena pachimake, chomwe chimadziwika kuti kugwetsa. Chifukwa cha shrinkage ndi zifukwa zina, mbali za pulasitiki nthawi zambiri zimakutidwa pakatikati kapena kutsekeredwa mu nkhungu. Pambuyo potsegula nkhungu, nkhunguyo siingathe kutulutsidwa, zomwe zimathandizirajekeseni akamaumba mankhwala kusiya nkhungu ndi kuteteza padziko jekeseni kuumbidwa mankhwala kuti zikande pa demolding. Popanga jekeseni wa jekeseni, malo amkati ndi akunja a jekeseni ovomereza

duct iyenera kukhala ndi ngodya yolowera motsatira njira yodutsira.

2.Zinthu kulimbikitsa kukula kwa demolding mbali ya mankhwala jekeseni kuumbidwa

1) Kukula kwa ngodya yowongoka kumadalira momwe jekeseni amapangidwira ndi geometry ya chinthucho, mwachitsanzo, kutalika kapena kuya kwa chinthucho, makulidwe a khoma ndi mawonekedwe apamwamba, monga roughness pamwamba, mizere yopangira, ndi zina zotero.

2) Pulasitiki yolimba imakhala ndi ngodya yayikulu kuposa pulasitiki yofewa;

3) Maonekedwe a mankhwala kuti apangidwe ndi jekeseni ndi ovuta kwambiri, kapena gawo la pulasitiki lokhala ndi mabowo ochulukirapo limafunikira ngodya yokulirapo;

4) Ngati kutalika kwa jekeseni wopangidwa ndi jekeseni ndi wamkulu ndipo dzenje ndi lakuya, ang'onoang'ono ang'onoang'ono amatengedwa;

5) Makulidwe a khoma la mankhwala opangidwa ndi jekeseni akuchulukirachulukira, mphamvu ya dzenje lamkati kuti imangirire pachimake ndi yayikulu, ndipo ngodya yolembera iyenera kukhala yayikulu.
