Kodi Rubber Molding ndi chiyani?

Kuumba mphira ndi njira yopangira yomwe imagwiritsidwa ntchito popanga zinthu za rabara zowumbidwa popanga zida za rabara kuti zikhale mtundu womwe mukufuna.Kuchita zimenezi kumaphatikizapo kugwiritsa ntchito nkhungu kapena chibowo kuti apereke mawonekedwe ndi mawonekedwe ake ku rabala, zomwe zimapangitsa kuti mphira ukhale ndi chinthu chomaliza chomwe chimafunidwa.Kuumba mphira ndi njira yosunthika yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana popanga zida za mphira zomwe zimagwiritsidwa ntchito mosiyanasiyana.

Pali mitundu ingapo ya njira zopangira mphira, iliyonse ndiyoyenera kugwiritsa ntchito mosiyanasiyana komanso zofunikira pazogulitsa.Mitundu ina yodziwika bwino yopangira mphira ndi:

Kuumba jekeseni:

Poumba jekeseni, mphira yaiwisi imatenthedwa mpaka itasungunuka ndipo kenako imabayidwa mu nkhungu mopanikizika kwambiri.Mphirawo umalimba mu nkhungu, kutenga mawonekedwe ake.Njirayi ndi yothandiza kwambiri popanga zida za mphira zovuta komanso zolondola.

Compression Molding:

Kumangirira kuphatikizirapo kuyika zinthu za rabara zomwe zidayezedwa kale pabowo lotseguka.Kenako nkhunguyo imatsekedwa, ndipo kukakamiza kumagwiritsidwa ntchito kukakamiza mphira, kupangitsa kuti itenge mawonekedwe a nkhungu.Kuponderezana kumapangidwira ndi koyenera kupanga mitundu yosiyanasiyana ya mphira yokhala ndi zovuta zosiyanasiyana.

Transfer Molding:

Transfer akamaumba amaphatikiza zinthu za jekeseni akamaumba ndi compression akamaumba.Zida za mphira zimatenthedwa kale ndikulowetsedwa m'chipinda, kenako plunger imakakamiza zinthuzo kulowa mu nkhungu.Njirayi imasankhidwa pazinthu zomwe zimafuna kulondola komanso kumveka bwino.

Kumangirira Kwamadzimadzi (LIM):

Kumangirira kwamadzimadzi kumaphatikizapo kubaya mphira wa silikoni wamadzimadzi m'bowo la nkhungu.Izi ndizofunikira makamaka popanga zida za rabara zosinthika komanso zovuta, zomwe nthawi zambiri zimagwiritsidwa ntchito pazida zamankhwala ndi zina zomwe ndizofunikira kwambiri.

Pakuumba:

Kumangira pamwamba kumaphatikizapo kuyika mphira wosanjikiza pagawo lomwe lilipo kapena chigawo chimodzi.Izi nthawi zambiri zimagwiritsidwa ntchito kuwonjezera chinthu chofewa kapena chowoneka bwino ku chinthu cholimba, kupangitsa kuti chigwire, chikhale cholimba, kapena chokongola.

Kusankhidwa kwa njira yopangira mphira kumadalira zinthu monga zovuta za gawolo, voliyumu yofunidwa, katundu wakuthupi, ndi kulingalira mtengo.Kumangira mphira kumagwiritsidwa ntchito kwambiri m'mafakitale amagalimoto, zakuthambo, zamagetsi, zamankhwala, ndi katundu wogula kuti apange zinthu zosiyanasiyana, kuphatikiza zisindikizo, ma gaskets, mphete za O, matayala, ndi zida zina zamphira.
