Zomwe zimayambitsa ndi njira zothetsera ming'alu ya pulasitiki

1. Kupanikizika kotsalira ndikokwera kwambiri

Pankhani ya ntchito ya ndondomeko, ndiyo njira yosavuta yochepetsera kupsinjika kotsalira pochepetsa kupanikizika kwa jekeseni, chifukwa kupanikizika kwa jekeseni kumafanana ndi kupsinjika kotsalira.Pankhani ya mapangidwe a nkhungu ndi kupanga, chipata chachindunji chokhala ndi kuchepa kwapang'onopang'ono komanso kuthamanga kwambiri kwa jekeseni kungagwiritsidwe ntchito.Chipata chakutsogolo chikhoza kusinthidwa kukhala zipata zingapo za singano kapena zipata zam'mbali, ndipo m'mimba mwake wa zipata zitha kuchepetsedwa.Popanga chipata cham'mbali, chipata cha convex chingagwiritsidwe ntchito chomwe chimatha kuchotsa gawo losweka mutatha kuumba.

2. Yotsalira kupsinjika maganizo ndende chifukwa cha kunja mphamvu

Pamaso demoulding mbali pulasitiki, ngati gawo mtanda gawo la demoulding ejection limagwirira ndi laling'ono kwambiri kapena chiwerengero cha ndodo ejector sikokwanira, malo a ejector ndodo n'zosaloleka kapena unsembe anafuna, bwino ndi osauka, ndi demoulding. kutsetsereka kwa nkhungu sikukwanira, ndipo kukana kwa ejection ndikokulirapo, kupsinjika maganizo kumayambitsidwa ndi mphamvu yakunja, zomwe zimapangitsa ming'alu ndi ming'alu pamwamba pa zigawo za pulasitiki.Pakakhala zolakwika zotere, chipangizo cha ejection chiyenera kuyang'aniridwa mosamala ndi kusinthidwa.

3. Ming'alu zomwe zimayambitsidwa ndi kuyika zitsulo

Kuchuluka kwa kutentha kwa thermoplastic ndi 9-11 kuwirikiza kawiri kuposa chitsulo ndi 6 kuwirikiza kuposa aluminium.Chifukwa chake, kuyika kwachitsulo mu gawo la pulasitiki kumalepheretsa kuchepa kwa gawo lonse la pulasitiki, ndipo kupsinjika kwamphamvu komwe kumabwera kumakhala kwakukulu.Kuchuluka kwa kupsinjika kotsalira kudzaunjikana mozungulira ndikuyika ming'alu pamtunda wa gawo la pulasitiki.Mwa njira iyi, zoyikapo zitsulo ziyenera kutenthedwa, makamaka pamene ming'alu yomwe ili pamwamba pa zigawo za pulasitiki ikuchitika kumayambiriro kwa makina, ambiri a iwo amayamba chifukwa cha kutentha kochepa kwa zoyikapo.

4. Kusankhidwa kosayenera kapena zonyansa zopangira

Zopangira zosiyanasiyana zimakhala ndi chidwi chosiyana ndi kupsinjika kotsalira.Nthawi zambiri, utomoni wopanda crystalline umakhala wovuta kupsinjika kotsalira komanso kusweka kuposa utomoni wa crystalline;Utoto womwe uli ndi zinthu zambiri zobwezerezedwanso umakhala ndi zonyansa zambiri, zimakhala zosasunthika kwambiri, kutsika kwamphamvu kwazinthuzo, ndipo sachedwa kusweka mtima.

5. Mapangidwe olakwika a zigawo zapulasitiki

Ngodya zakuthwa ndi notch mu gawo la pulasitiki ndizomwe zimapangitsa kuti pakhale kupsinjika, zomwe zimapangitsa ming'alu ndi ming'alu pamtunda wa gawo la pulasitiki.Choncho, ngodya zakunja ndi zamkati za gawo la pulasitiki ziyenera kupangidwa kukhala ma arcs okhala ndi utali wochuluka momwe angathere.

6. Ming'alu pa nkhungu

Popanga jekeseni, chifukwa cha kubwereza mobwerezabwereza kwa jekeseni pa nkhungu, ming'alu ya kutopa idzachitika m'mphepete mwake ndi ngodya zapakatikati, makamaka pafupi ndi mabowo ozizira.Ngati ming'alu yotereyi yang'ambika, nthawi yomweyo fufuzani ngati pamwamba pa ng'anjo yofanana ndi ming'aluyo ili ndi mng'alu womwewo.Ngati ming'aluyo imayambitsidwa ndi kusinkhasinkha, nkhunguyo iyenera kukonzedwa ndi makina.

Mankhwala wamba pulasitiki m'moyo, mongaophika mpungamakina a sandwich,zotengera zakudya, mabokosi a pulasitiki nkhomaliro, zitini zosungira,zopangira mapaipi apulasitiki, etc., angathe kupewa ming'alu pamwamba.
