In Kuwedzera Blow Kugadzira (EBM), ipurasitiki inonyungudutswa uye inopamhidzirwa mukati mehomba tube (parison). Iyi parison inozobatwa nekuivhara mukati mekuumbwa kwesimbi yakaumbwa. Mhepo inobva yaridzirwa muparoni, ichichiisa muchimiro chehako bhodyera, mudziyo, kana chikamu. Mushure mekunge mapurasitiki apera kunyatsokwana, kuumbwa kunovhurwa uye chikamu chacho chobva chakandwa. Kuenderera uye Intermittent ndiwo maviri akasiyana eExprusion Blow Kuumba. Mukuenderera mberi Kuwedzeredza Kuridza Kurovera parison kunozopfuurira mberi uye zvikamu zvega zvinogurwa nebanga rakakodzera. MuIntermittent blowing kuumba kune maviri maitiro: yakananga kupindirana yakafanana nekukuvara jekiseni iyo iyo banga inoshanduka, ndokumira uye kusundira yakanyungudika kunze. Nayo nzira yekuunganidza mari Muchiitiko ichi chikwangwani chinogona kutenderera chichienderera kana chisingapindiki. nekuenderera mberi nekuwedzeredza uremu weparoni inodhonza parison uye kuita kuti calibrating kumadziro kukora kuve kwakaoma. Iyo yekudzivirira musoro kana kudzorera nzira yekushandisa inoshandisa hydraulic masisitimu kusundira parison nekukurumidza ichideredza mhedzisiro yeuremu uye kubvumira chaiyo kutonga pamusoro pamadziro nekugadzika kufa kwegeji ine parison programming kifaa.
EBM maitiro inogona kunge ichienderera (ingogara ichionekwa parison) kana nepakati. Mhando dzemidziyo yeEBM inogona kuverengerwa zvinotevera:
Kuenderera mberi extrusion michina
- rotary vhiri kufuridza kuumba masisitimu
- shuttle machina
Intermittent extrusion michina
- kudzoreredza screw michina
- accumulator musoro michina
Mienzaniso yezvikamu zvakagadzirwa nemaitiro eEBM inosanganisira yakawanda polyethylene hollow zvigadzirwa, mukaka mabhodhoro, shampoo mabhodhoro, mota ducting, kudiridza matangi uye hollow maindasitiri zvikamu zvakadai sedhiramu.
Zvakanakira zvekuvhuvhuta zvinosanganisira: yakaderera mudziyo uye kufa kwemutengo; kukurumidza kugadzirwa mitengo; kugona kwekuumbwa kwakaoma chikamu; Handles inogona kuverengerwa mune dhizaini.
Dambudziko rekupusha kuumbwa rinosanganisira: mashoma kune hollow zvikamu, yakaderera simba, kuwedzera zvipingamupinyi zvinhu multilayer parisons yezvakasiyana zvinhu zvinoshandiswa saka hazvigadzirisike. Kugadzira hupamhi hwemitsipa mitsipa inotenderera kuyerera kunokosha
Spin kucheka
Midziyo yakadai semaroja inowanzove neakawandisa ezvinhu nekuda kwekuumbwa kwekuumbwa. Izvi zvinogadziriswa nekupuruzira banga pakareva mudziyo unocheka zvinhu zvacho. Iyi purasitiki yakawandisa inogadziridzwa zvakare kuti igadzire kuumbwa kutsva. Spin Trimmers anoshandiswa pane dzinoverengeka zvigadzirwa, sePVC, HDPE uye PE + LDPE. Mhando dzakasiyana dzezvishandiso zvacho zvine zvadzo zvehunhu zvinokanganisa kukonzeresa. Semuenzaniso, kuumbwa kunogadzirwa kubva kuamorphous zvinhu kwakanyanya kuoma kuoma kupfuura zvigadzirwa zvemakristalline. Titanium yakavharwa mabhii inowanzo shandiswa kwete yakajairwa simbi yekuwedzera hupenyu nechinhu chinosvika makumi matatu.
