Blow isikhunta design kanye umjovo isikhunta ukufana kanye umehluko, kufanele sinake ini?

1. Inqubo yokuklama isikhunta se-Blow ihlukile, umklamo wokubumba wokubumba umjovo + ushaya;Ukubumba umjovo umjovo + ukucindezela;Ukubunjwa kwe-roll kuyi-extrusion + ingcindezi;Ukubumba ukuvuthela kufanele kube nekhanda elishiywe yipayipi lokumunca, ukubumba komjovo kufanele kube nengxenye yesango, ukusika kwepulasitiki okugoqekayo kufanele kube ne-burr

Idizayini yokubumba yokubumba yokushaya

2. Ngokuvamile, ukubumba umjovo kuwumgogodla oqinile, ukubumba igalelo nokubumba umqulu kuwumgogodla ongenalutho.Izingxenye zomjovo ezingaphezulu ziyagqama, i-blow and roll plastic surface ayilingani.Ukubumba i-Blow kanye ne-roll molding ukuqhathanisa okungenani i-blow molding inomlomo ophephethayo.Lesi isiqhathaniso esijwayelekile.Kazi niyazwisisa!!

3. Ukuncipha kwamapulasitiki kanye nezici zawo ezinomthelela

I-Thermoplastics inendawo yokukhula lapho ishiselwa, inkontileka lapho ipholile, futhi vele iyancipha lapho icindezelwa.Enkambweni yokubunjwa komjovo, ipulasitiki encibilikisiwe iqala ukujova emgodini wesikhunta, ngemva kokugcwalisa, ukuncibilika kupholile futhi kuqiniswe, futhi ukuncipha kwenzeka lapho izingxenye zepulasitiki zikhishwa esikhunjini, okubizwa ngokuthi ukwakha i-shrinkage.Izingxenye zepulasitiki kusukela ekubunjweni kuya ekuzinzeni kwalesi sikhathi sesikhathi, kusazoba noshintsho oluncane ngosayizi, ushintsho luwukuqhubeka nokuncipha, lokhu kuncipha kubizwa ngokuthi i-post-shrinkage.Okunye okuhlukile wukwandiswa kwamapulasitiki athile ane-hygroscopic ngenxa yokumuncwa komswakama.Isibonelo, uma okuqukethwe kwamanzi enayiloni 610 kungu-3%, ukukhuphuka kosayizi ngu-2%;Lapho inani lamanzi le-glass fibre inayiloni engu-66 eqinisiwe ingu-40%, ukwanda kosayizi ngu-0.3%.Kodwa ukwakha ukuncipha kudlala indima enkulu.
