Kuti zinthuzo zikhale zogwirizana ndi zosowa za anthu ambiri, zinthu zambiri zomangira zomwe zimapangidwa ziyenera kupakidwa utoto pamwamba. Pali njira zosiyanasiyana zochizira pamwamba pa zinthu zomangira mankhwala tsiku ndi tsiku. Pano tikuyambitsa njira zingapo zodziwika bwino mumakampani opanga zodzikongoletsera, monga vacuum covering, spraying, electroplating, anodizing, injection molding ndi kusintha mtundu.
1. Kufotokozera kwa ndondomeko ya Vacuum ❖ kuyanika
Chophimba cha vacuum chimatanthauza mtundu wa chinthu chomwe chimayenera kuphimbidwa ndi vacuum yapamwamba. Chophimba cha filimu chomwe chiyenera kuphimbidwa chimayikidwa mu evaporator ya vacuum, ndipo pampu ya vacuum imagwiritsidwa ntchito kutulutsa vacuum mu chophimbacho kufika pa 1.3 × 10-2 ~ 1.3 × 10-3Pa. Chophimbacho chimatenthedwa kuti chisungunuke ndikusanduka waya wa aluminiyamu woyeretsedwa kwambiri (woyera 99.99%) pa kutentha kwa 1200℃ ~ 1400℃ kupita ku aluminiyamu woyeretsedwa. Tinthu ta aluminiyamu woyeretsedwa timayikidwa pamwamba pa chogwirira cha filimu chosuntha, ndipo pambuyo poziziritsa ndi kuchepetsa, gawo losalekeza komanso lowala la aluminiyamu lachitsulo limapangidwa.
2.Makhalidwe a ndondomeko ya kupaka utoto wa Vacuum
Mtengo wa ndondomeko: mtengo wa nkhungu (palibe), mtengo wa unit (wapakati)
Zotulutsa zoyenera: chidutswa chimodzi mpaka gulu lalikulu
Ubwino: wapamwamba kwambiri, kuwala kwakukulu komanso mawonekedwe oteteza pamwamba pa chinthu
Liwiro: liwiro lapakati lopanga, maola 6 pa nthawi (kuphatikizapo kujambula)
3. Kapangidwe ka dongosolo la ndondomeko ya kupaka vacuum
1. Zipangizo zamagetsi
Kuphimba ndi vacuum plating ndiye njira yodziwika bwino yochizira pamwamba pa chitsulo. Popeza palibe nkhungu yomwe imafunika, mtengo wa njirayi ndi wotsika kwambiri, ndipo mitundu yofanana ndi yamoyo ingagwiritsidwenso ntchito pophimba ndi vacuum plating, kotero kuti pamwamba pa chinthucho pakhoza kukhala ndi zotsatira za aluminiyamu wodzozedwa, chrome yowala, golide, siliva, mkuwa ndi chitsulo cha mfuti (chopangidwa ndi mkuwa ndi tin). Kuphimba ndi vacuum plating kumatha kupangitsa pamwamba pa zinthu zotsika mtengo (monga ABS) kukhala ndi zotsatira za pamwamba pa chitsulo pamtengo wotsika. Pamwamba pa workpiece yophimbidwa ndi vacuum plated payenera kukhala kouma komanso kosalala, apo ayi izi zidzakhudza kwambiri zotsatira za pamwamba.
2. Zipangizo zogwiritsidwa ntchito
Zipangizo zachitsulo zitha kukhala golide, siliva, mkuwa, zinki, chromium, aluminiyamu, ndi zina zotero, zomwe aluminiyamu imagwiritsidwa ntchito kwambiri. Zipangizo zapulasitiki zimagwiritsidwanso ntchito, monga ABS, ndi zina zotero.
4. Chiyerekezo cha kayendedwe ka njira
Tiyeni titenge chitsanzo cha gawo la pulasitiki: thirani kaye gawo la primer pa workpiece, kenako perekani electroplating. Popeza workpiece ndi gawo la pulasitiki, thovu la mpweya ndi mpweya wachilengedwe zidzatsala panthawi yopangira jakisoni, ndipo chinyezi mumlengalenga chidzayamwa chikayikidwa. Kuphatikiza apo, popeza pamwamba pa pulasitiki sipali pokwanira, pamwamba pa workpiece yomwe imayikidwa ndi electroplating sipali posalala, kuwala kwake kuli kochepa, chitsulo sichikumva bwino, ndipo padzakhala thovu, ma blister ndi zinthu zina zosafunikira. Mukapopera gawo la primer, pamwamba pake padzapangidwa losalala komanso lathyathyathya, ndipo thovu ndi ma blister omwe alipo mu pulasitiki yokha adzachotsedwa, kuti mphamvu ya electroplating iwonetsedwe.
5.Kugwiritsa ntchito mumakampani opanga zodzikongoletsera
Chophimba cha vacuum chimagwiritsidwa ntchito m'makampani opanga zodzikongoletsera, monga zida zakunja za chubu cha milomo, zida zakunja za mutu wa pampu, mabotolo agalasi, zida zakunja za chivundikiro cha botolo, ndi zina zotero.
