Kodi pali kusiyana kotani pakati pa jekeseni wa pulasitiki ndi kuponyera kufa?
Zinthu zopangidwa ndi jekeseni ndi zigawo zopangidwa ndi mapulasitiki pogwiritsa ntchito makina opangira jekeseni ndi nkhungu kuti zikhale zoumbidwa, pomwe zinthu zopangidwa ndi kufa ndi zida zopangidwa ndi zitsulo kudzera pamakina ojambulira ndi nkhungu zoponyera kufa, ndizofanana kwambiri pazida, makina opangira ndi njira zopangira.Lero tiyeni tione kusiyana kwa jekeseni akamaumba ndi kufa kuponyera mu m'munsimu mfundo 10.
1. Zida: Kumangira jekeseni wa pulasitikinthawi zambiri amagwiritsa ntchito zinthu zotsika kutentha monga thermoplastics, pomwe kuponyera kufa nthawi zambiri kumafuna zinthu zotentha kwambiri monga zitsulo.

2. Mtengo: Kufa kuponyanthawi zambiri imakhala yokwera mtengo kuposa kuumba jekeseni wa pulasitiki chifukwa pamafunika kutentha kwambiri komanso zida zapadera.
Mitengo yokhudzana ndi kufa kwa gawo limodzi imaphatikizapo:
• Mtengo wa zipangizo zomwe zimagwiritsidwa ntchito popanga, monga ma aloyi ndi mafuta.
• Mtengo wamakina omwe amagwiritsidwa ntchito poponya kufa (makina opangira jakisoni, makina a CNC, Kubowola, kugogoda, ndi zina zotero).
• Mtengo uliwonse wokhudzana ndi kukonza ndi kukonza makina ndi zida.
• Ndalama zogwirira ntchito monga zokhudzana ndi kukhazikitsa, kuyendetsa ndi kuyang'ana ndondomekoyi komanso kuopsa kwa ngozi chifukwa chitsulo chikanakhala kutentha kwambiri.
• Opaleshoni yachiwiri monga positi processing kapena kumaliza chithandizo chomwe chingakhale chofunikira pazigawo zina.Poyerekeza ndi mbali pulasitiki, padzakhala zambiri yachiwiri Machining mtengo ndi pamwamba mtengo monga anodizing, plating ndi ❖ kuyanika, etc,.
• Ndalama zotumizira kutumiza magawo omalizidwa kumene akupita.(Zigawozi zidzakhala zolemera kwambiri kuposa zigawo za pulasitiki, kotero kuti mtengo wotumizira udzakhala wokwera kwambiri. Kutumiza panyanja kungakhale chisankho chabwino, koma kumangofunika kukonzekera kale chifukwa sitima zapamadzi zimafuna nthawi yochuluka.)
Mtengo wokhudzana ndi kuumba jekeseni wa pulasitiki gawo limaphatikizapo:
• Mtengo wa zipangizo zomwe zimagwiritsidwa ntchito pokonzekera, kuphatikizapo utomoni ndi zowonjezera.
• Mtengo wa makina opangira jakisoni wapulasitiki.(Nthawi zambiri, mbali zapulasitiki zimatha kukhala ndi mawonekedwe abwino athunthu pambuyo pakuwumba, chifukwa chake padzakhala mtengo wocheperako pakukonza kwachiwiri.)
• Mtengo uliwonse wokhudzana ndi kukonza ndi kukonza makina ndi zida.
• Ndalama zogwirira ntchito monga zokhudzana ndi kukhazikitsa, kuyendetsa ndi kuyang'anira ndondomekoyi.
• Opaleshoni yachiwiri monga positi processing kapena kumaliza chithandizo chomwe chingakhale chofunikira pazigawo zina.(kubisa, zokutira kapena silika-screen)
• Ndalama zotumizira kutumiza magawo omalizidwa kumene akupita.(Pulasitiki siwolemerera ngati wamalingaliro, nthawi zina pakufunika mwachangu, amatha kutumizidwa ndi ndege ndipo mtengo wake udzakhala wotsika kuposa magawo achitsulo.)
3. Nthawi Yosinthira:Kumangira jekeseni wa pulasitiki nthawi zambiri kumakhala ndi nthawi yosinthira mwachangu kuposa kuponyera kufa chifukwa cha njira yake yosavuta.Nthawi zambiri, mankhwala opangidwa ndi jekeseni safuna makina achiwiri pomwe mbali zambiri zoponyera zimayenera kuchita makina a CNC, kubowola, ndikugogoda musanatsirize.
4. Kulondola:Chifukwa cha kutentha kwakukulu komwe kumafunikira poponya kufa, mbali zake sizikhala zolondola kwambiri kuposa zomwe zimapangidwa ndi jekeseni wa pulasitiki chifukwa cha kuchepa ndi kuphulika ndi zina.
5. Mphamvu:Ma die castings ndi amphamvu komanso olimba kuposa omwe amapangidwa pogwiritsa ntchito njira zopangira jakisoni wapulasitiki.
6. Kuvuta kwa Mapangidwe:Kumangira jakisoni wapulasitiki ndikoyenera pazigawo zokhala ndi mawonekedwe ovuta, pomwe kufa kwakufa kuli bwino kuti apange magawo ofananira kapena okhala ndi zocheperako.
7. Kumaliza & Kupaka utoto:Magawo opangidwa ndi jekeseni amatha kukhala ndi mitundu yambiri yamalire ndi mitundu poyerekeza ndi ma castings akufa.Kusiyana kwakukulu pakati pa kutsirizitsa mankhwala a jekeseni kuumbidwa mbali ndi kufa castings mbali ndi zinthu ntchito.Ma die castings amapangidwa ndi zitsulo zomwe zimafunikira makina owonjezera kapena kupukuta kuti akwaniritse zomwe akufuna.Mbali ina yopangidwa ndi jekeseni wa pulasitiki, nthawi zambiri imatsirizidwa pogwiritsa ntchito mankhwala otenthetsera komanso zokutira mankhwala, zomwe nthawi zambiri zimabweretsa malo osalala kuposa omwe amapezedwa ndi makina kapena kupukuta.
8. Kukula kwa Gulu & Kuchuluka Kwapangidwa:Njira zosiyanasiyana zimapanga magawo osiyanasiyana amitundu yosiyanasiyana;jekeseni wa pulasitiki amatha kupanga mamiliyoni a zidutswa zofanana nthawi imodzi, pamene ma die cast amatha kupanga zidutswa zofanana zikwizikwi nthawi imodzi kutengera zovuta / mawonekedwe awo ndi / kapena nthawi zokhazikitsira zida zomwe zimakhudzidwa pakati pa magulu (ie, nthawi zosintha) .
9. Zida Zozungulira Moyo:Zida zakufa zimafunikira kuyeretsa ndi kukonza zambiri chifukwa zimafunikira kupirira kutentha kwakukulu;Kumbali ina, nkhungu za jekeseni wa pulasitiki zimakhala ndi moyo wautali chifukwa cha kutentha kwake kochepa panthawi yopangira zomwe zingathandize kuthetsa ndalama zomwe zimagwirizanitsidwa ndi tooling/setup time/etc.
10 .Zokhudza Zachilengedwe:Chifukwa cha kutentha kwawo kozizira, zinthu zopangidwa ndi jekeseni wa pulasitiki nthawi zambiri zimakhala ndi vuto lochepa la chilengedwe poyerekeza ndi zida zakufa monga zinc alloy parts zomwe zimafuna kutentha kwapamwamba kwambiri kuti apange magawo.
