Bhodhoro Blow molding screw barrel dhizaini inomira parutivi kubva mukuumbwa kwejekiseni nekuda kwehurefu hwayo uye yakakwirira compression ratio. Izvi zvinobatsira kugadzira yunifomu parisons, iyo inovandudza kujeka kwebhodhoro uye kusimba. Sezvo musika wepasi rose wakaumbwa wepurasitiki uchikura, iwoKufuridza Screw BarreluyeFirimu Inoputika Chikukuruunza kunyungudika kwakanaka, kusanganisa, uye kuchengetedza simba pamusoro peSingle Plastic Screw Barrel.
Screw Barrel Basa muMolding Maitiro
Kunyunguduka Kwezvinhu uye Basa Rokupa
Iyo screw barrel inoita semoyo wezvose zviri zviviri bhodhoro kuumba nekuumba jekiseni muchina. Basa rayo guru nderekunyungudutsa mapepa epurasitiki uye kufambisa zvinhu zvakanyungudutswa mberi. Mukuumba jekiseni, screw inotenderera mukati membiya inopisa, ichimanikidza uye ichinyungudutsa plastiki. Kana purasitiki yanyunguduka, screw inoisundira muforoma pakumanikidzwa kukuru. Iyi nzira inoumba plastiki kuita zvikamu zvakasimba.
Mukuumba bhodhoro, screw barrel inonyungudutsa iyo polymer. Zvisinei, mafambisirwo azvinoitwa zvinhu anogona kuchinja. Semuenzaniso, mu extrusion blow molding, screw inogona kutendeuka ichienderera kana mumatanho. Inosaidzira purasitiki yakanyungudutswa kunze sechubhu, inonzi parison. Mhepo inobva yavhuvhuta ichipinda muprison kuita bhodhoro. Mukuumba jekiseni, screw inopinza purasitiki yakanyungudutswa muforoma kugadzira preform, inozova bhodhoro. Iyo screw barrel inogadzirisa basa rayo zvichienderana nemaitiro ekuumba, asi inogara yakatarisana nekunyunguduka uye kufambisa purasitiki zvakanaka.
Zano:Iyo yakagadzirwa zvakanaka screw barrel inovimbisa kuti plastiki inonyunguduka zvakaenzana uye inoyerera zvakanaka, iyo inobatsira kudzivirira kukanganisa mune yekupedzisira chigadzirwa.
Kusanganiswa uye Homogeneity Migumisiro
Kusanganisa uye homogeneity kunoita basa rakakura mumhando yechigadzirwa. Iyo screw barrel inofanirwa kusanganisa purasitiki uye chero zvekuwedzera kuitira kuti chikamu chekupedzisira chitarise uye chiite sezvanga zvichitarisirwa. Yakasiyana screw dhizaini inogona kushandura masanganiswa epurasitiki. Semuyenzaniso, screws ane akakosha chiteshi kana kusanganisa zvikamu zvinobatsira kugovera colorants uye zvinowedzera zvakaenzana. Izvi zvinotungamirira kune mavara ari nani uye mashoma asina simba mavara.
Vagadziri vanowanzo edza kuti screw inosanganiswa sei nekutarisa tembiricha uye ruvara rwepurasitiki yakanyungudutswa. Vanotarisa kunyange tembiricha uye musanganiswa wemavara akatsetseka. A lowermureza kutsaukamuzviedzo izvi zvinoreva kusanganisa kuri nani. Mamwe masiruuru epamberi, senge zvipingamupinyi kana madhizaini akawanda, anoratidza kusanganiswa kwakagadziridzwa uye mamwe mayunifomu anonyungudika. Aya maficha anobatsira kugadzira mabhodhoro uye zvikamu zvakasimba, zvakajeka, uye zvisina mitsetse kana mabhubhu.

Misiyano Yakakosha muScrew Barrel Dhizaini
Geometry uye Dimensions
Screw barrel geometry maumbirwo mafambisirwo epurasitiki uye kunyungudika mukati memuchina. Mukuumba bhodhoro, screw barrel inowanzova nehurefu-kusvika-diameter (L / D) reshiyo kana ichienzaniswa nekuumbwa kwejekiseni. Uhu hurefu hwakawedzerwa hunopa plastiki nguva yakawanda yekunyunguduka uye kusanganisa, izvo zvakakosha pakugadzira mabhodhoro akasimba, akajeka. Iyo Bhodhoro Blow molding screw barrel inowanzo ratidza zvishoma nezvishoma taper uye yakadzika mafidhi nzira. Idzi sarudzo dzekugadzira dzinobatsira screw kubata kuyerera kwakadzikama kwepurasitiki uye kugadzira yunifomu parison.
Injection molding screw barrels, kune rumwe rutivi, inowanzove ipfupi. Vanotarisa nekukurumidza kunyunguduka uye kupinza plastiki muforoma. Hurefu hupfupi hunobatsira kukurumidza kutenderera nguva uye inokodzera kukurumidza-paced chimiro chekuumba jekiseni. Iyo geometry yega yega screw barrel inoenderana nezvinodiwa zvemaitiro ayo, kuenzanisa kunyungudika, kusanganisa, uye kudzvanywa.
Ongorora: Iyo chaiyo geometry inogona kunatsiridza kunyunguduka uye kuderedza kushandiswa kwesimba nekudzora kuwanda kwekugera uye kupisa zviitiko zvepurasitiki.
Compression Ratio uye Functional Zones
Iyo compression ratio chikamu chakakosha che screw barrel dhizaini. Iyo inoyera kuti yakawanda sei screw inodzvanya purasitiki painofamba kubva kunzvimbo yekudyisa ichienda kunzvimbo yemamita. Mukuumba bhodhoro, Bhodhoro Blow kuumba screw barrel inowanzoshandisa yakakwira compression ratio. Izvi zvinobatsira kuvaka dzvinyiriro inodiwa kuti iite parini yakatsetseka, isina bubble. Iyo yepamusoro reshiyo zvakare inovandudza kusanganisa uye kunyungudika homogeneity, izvo zvinotungamira kune nani kujeka kwebhodhoro uye kusimba.
Injection molding screw barrels inogona kushandisa yakaderera kana ine mwero compression reshiyo, zvichienderana nezvinhu. Semuenzaniso, yakaderera compression reshiyo inogona kukonzera kuremara senge splay mu polystyrene, nepo reshiyo yepamusoro inovandudza compaction uye inoderedza kutenderera nguva. Nekudaro, kana reshiyo yakawandisa kune zvimwe zvinhu zvakaita seABS, inogona kukonzera kusagadzikana kwemaitiro uye kunyungudika kusina kukwana. Dhizaini yenzvimbo dzinoshanda-yekudya, shanduko, uye metering-inotambawo basa guru. Kugadzirisa kudzika uye kureba kwenzvimbo idzi kunoshandura kuti mapurasitiki anonyungudika nekuyerera sei, zvichikanganisa kudzvanywa uye kuita screw.
- Compression ratio inofanirwa kuenderana nerudzi rwepolymer uye maitiro ezvinodiwa.
- Dhizaini yakakodzera yenzvimbo dzinoshanda inovimbisa kunyungudika kwakadzikama uye inodzivirira kukanganisa.
- Kunyatsogadzirisa zvinhu izvi zvinogona kuvandudza kunaka kwekunyunguduka uye kuwedzera simba rechirimwa.
Material Kubata uye Plasticizing Zvinodiwa
Akasiyana ekuumba maitiro ane akasiyana eplasticizing zvinodiwa. Iyo Bottle Blow molding screw barrel inofanirwa kubata zvakasiyana-siyana zvezvinhu, kubva pakakwirira-density polyethylene (HDPE) kusvika ku polypropylene (PP). Inoda kunyunguduka nekusanganisa zvinhu izvi zvakaenzana kugadzira parini ine ukobvu hunoenderana. Izvi zvakakosha nekuti kunyungudika kusina kuenzana kunogona kutungamirira kunzvimbo dzisina simba kana mabhodhoro ane makore.
Injection molding screw barrels inotarisa kukurumidza kunyungudutsa purasitiki uye kuipinza muforoma. Ivo vanowanzo shanda nezvinhu zvinoda kunyatso kudzora tembiricha uye nekukurumidza plasticizing. Zvimwe zvinhu, sengehigh-viscosity resins, inogona kuve yakaoma kugadzirisa mukuumba jekiseni kuvhuvhuta. Iyo screw barrel dhizaini inofanirwa kuverengera misiyano iyi kuti ive nechokwadi chekushanda kwakanaka.
| Aspect | Extrusion Blow Molding (EBM) | Jekiseni Blow Molding (IBM) |

Zano: Kufananidzascrew barrel designkuzvinhu uye maitiro anobatsira kuderedza zvimedu, kunatsiridza kujeka, uye kugadzira mabhodhoro akasimba.
Pfeka Resistance uye Material Kuenderana
Kupfeka kuramba ndiko kunetseka kukuru kune ese ari maviri kuvhuvhuta bhodhoro nekuumba jekiseni. Iyo screw uye mbiya inotarisana inogara ichikweshana uye kumanikidza kubva mupurasitiki inofamba. Mafirita uye ekuwedzera mupurasitiki anogona kuita kuti kupfeka kuve kwakanyanya. The Bottle Blow moldingscrew barrelkazhinji inoshandisa yemhando yepamusoro nitrided simbi, bimetallic alloys, kana akakosha machira senge tungsten carbide kurwisa kupfeka uye ngura. Zvinhu izvi zvinobatsira screw kugara kwenguva refu, kunyangwe kana ichigadzira abrasive kana corrosive polymers.
Majekiseni ekuumba madhiramu anogona kushandisa zvinhu zvakaita seNitralloy nitride, D2 chishandiso simbi, CPM 10V, kana kunyange carbide kumabasa akaomarara. Chinhu chega chega chinopa mazinga akasiyana ekudzivirira kubva pakupfeka uye ngura. Semuyenzaniso, CPM 10V inoshanda zvakanaka nemapurasitiki akazadzwa negirazi kana anodzoreredza moto, ukuwo madhiramu ecarbide ari akanakisa pazvinhu zvinokurisa. Kufananidza screw uye dhiramu zvinhu zvakakosha kudzivirira matambudziko nekuwedzera kwekupisa uye kusunga.
- Nyaya dzekupfeka dzakajairika dzinosanganisira kuroora, kupfeka abrasive, uye kusarongeka kupfeka.
- Kushandisa zvinhu zvakakodzera uye machira kunowedzera hupenyu hwe screw barrel.
- Kugara uchiongorora maitiro ekupfeka kunogona kubatsira kuona matambudziko ekutanga uye kutungamira dhizaini yekuvandudza.
Rangarira: Iyo yakanyatsosarudzwa screw barrel material inochengeta muchina uchishanda zvakanaka uye inoderedza nguva yekudzikira pakugadzirisa.
Bhodhoro Blow Molding Screw Barrel Features
Dhizaini Magadzirirwo eParison Hunhu
Vagadziri vanogadzira Bhodhoro Blow molding screw barrel ine akati wandei maficha ekuvandudza eparison mhando. Izvi zvinogadziriswa zvinobatsira kugadzira mabhodhoro ane kunyange madziro uye nzvimbo dzakatsetseka. Heano mamwe ezvakanyanya kukosha dhizaini sarudzo:
