Chii chinonzi Extrusion Molding?
Extrusion molding, inozivikanwawo seextrusion mukugadzirwa kwepurasitiki, inoshandisa hydraulic pressure kumanikidza zvinhu kuburikidza neforoma, ichigadzira zvikamu zvinoenderera zvemaumbirwo akasiyana. Kuita uku kunosanganisira kudziyisa zvinhu sezvo zvichisundirwa kumberi nescrew kuburikidza nedhiramu, zvichikonzera kuumbwa kweanoenderera profiles kana semi-zvigadzirwa. Extrusion molding, tekinoroji yekutanga mukugadziriswa kwepolymer, yakashanduka mukati memakore zana apfuura ikava nzira inoshanda, inoenderera, ine mutengo wakaderera ine kushanda kwakafara. Ikozvino ndiyo inonyanya kushandiswa kuumba nzira muindasitiri yekugadzira polymer nekuda kwekuchinjika kwayo, mitengo yakakwira yekugadzira, uye kuita zvakasiyana.
Basic Maitiro muExtrusion Molding
1. Kudyisa
Plastic material inodyiswa muhopper uye inofamba ichipinda muscrew channels pasi pesimba regiravhiti kana nerubatsiro rwe feeder, ichienda kumusoro unofa.
2. Kutumira
Sezvo plastiki inopinda mugero yekukurisa, inoenda kumberi neimwe screw rotation. Iyo chaiyo yekufambisa mwero inoenderana nekukweshana coefficients epurasitiki pakatarisana nedhiramu uye screw. Kukweshana kwepamusoro nedhiramu kana kukweshana kwepasi nescuru kunowedzera kufamba kwepurasitiki kumberi.
3. Kutsikirira
Kudzvanya kwakakosha mukuumba extrusion. Purasitiki haina kunaka conductor yekupisa, uye chero mapeji ari pakati pezvimedu anogona kutadzisa kupisa kupisa, zvichikanganisa kunyungudika. Kudzvanya kunobatsira kudzinga magasi kubva muzvinhu, kudzivirira kukanganisa, uye inova nechokwadi chehuwandu hwechigadzirwa nekuchengetedza yakanyanya kudzvanywa system.
4. Kunyunguduka
Nekumanikidza kuri kuwedzera, iyo inofamba yakasimba yepurasitiki inobatika uye inokwesha pakatarisana neyakapisa dhiramu madziro, ichigadzira yakatetepa yakanyunguduka firimu. Iyi firimu inokweshwa nescrew painofamba, ichiungana pamberi pescrew ndege uye kugadzira dziva rekunyungudika.
5. Kusanganisa
Pasi pekudzvinyirirwa kwakanyanya, iyo yakasimba zvinhu inobatanidzwa kuita dense plug. Kusanganiswa kunoitika chete pakati pezvikamu zvakanyungudutswa, kwete mukati mepuragi yakasimba.
6. Kunetesa
Ventilation yakakosha kubvisa magasi uye mhute inogadzirwa panguva ye extrusion process. Kufefetera kwakaringana kunovimbisa kunaka kwechigadzirwa chekupedzisira nekudzivirira voids uye hurema.
Zvakanakira Extrusion Molding
Zviri Nyore Zvishandiso zvine Yakaderera Investment: Iwo muchina we extrusion molding wakatwasuka uye unodhura-unoshanda.
Kuenderera Kugadzirwa NeKubudirira Kwepamusoro: Extrusion inobvumira kuenderera mberi kugadzirwa, kuwedzera kushanda zvakanaka.
Yakakwira Dhigirii yeAutomation: otomatiki inoderedza kuwanda kwevashandi uye inowedzera kunyatsoita.
Nyore Kushanda uye Maitiro Kudzora: Iyo maitiro ari mushandisi-ane hushamwari uye anogoneka.
Uniform uye High-Quality Zvigadzirwa: Iyo extrusion process inogadzira inowirirana uye yakakora zvigadzirwa.
Wide Material Kuenderana: Mazhinji thermoplastics uye zvimwe thermosetting zvinhu zvinogona kushandiswa.
Versatile Applications: Extrusion molding inokodzera zvigadzirwa zvakasiyana, zvichiita kuti ive yakawanda inoshanda maitiro.
Compact Production Lines: Iyo nzira inoda shoma nzvimbo uye inochengetedza yakachena kugadzirwa nharaunda.
Mafungiro Akakosha muExtrusion Molding
Pre-kutanga Cheki: Ongorora dhiramu, hopper, uye zvisungo, kuve nechokwadi chekuti zvese zvikamu zvakachengeteka. Mafuta sezvinodiwa uye chenesa midziyo.
Yakaderera-Speed Kutanga: Kutanga shandisa screw pakumhanya kwakaderera, kutarisa kune chero zvisizvo mukuita kwemota kana ruzha.
Pfupi Hapana-mutoro Miedzo: Limit screw muyedzo unomhanya kusvika maminetsi makumi matatu usati wanamatira kugadzira mold, uchizora iyo mold mabhaudhi kuti abvise.
Kudya zvishoma nezvishoma: Tanga neakaderera screw kumhanya uye dyisa zvinhu zvakaenzana, uchitarisa chero kuchinja kwemota ikozvino.
Temperature Monitoring: Ramba uchitarisa kubereka tembiricha, kuve nechokwadi kuti hapana kutarisana zvakananga nezvikamu zvinofamba panguva yekushanda.
Surface Roughness Solutions: Wedzera tembiricha, gadzirisa screw speed, tsiva mafirita, uye shandisa akakodzera ekuomesa maajenti kudzivirira kuremara kwepasi.
Kudzivirira Kudzivirirwa: Deredza kushandiswa kwemafuta, kunatsiridza zvivakwa zvezvinhu, kana kuisa Teflon coatings kuderedza kuyera.
Kuchengetedza Kubuda Kwakagadzikana: Kugadzirisa kuchinjika nekugadzirisa mamiriro, uchishandisa akasiyana screw maumbirwo, uye kudzora tembiricha kusiyanisa kuti ive nechokwadi chakafanana extrusion.
Zvishandiso zveExtrusion Molding
Plastic extrusion profiles yakanakira kugadzira mapaipi, mapikicha emasuo, zvikamu zvemotokari, nezvimwe.
1. Mapaipi uye Tubing
Extrusion inowanzoshandiswa kugadzira mapaipi epurasitiki uye tubing kubva kune zvinhu zvakaita sePVC uye mamwe thermoplastics.
2. Wire Insulation
Mazhinji thermoplastics akanakisa insulators, achivaita akakodzera extruding waya uye tambo insulation uye sheathing, kusanganisira fluoropolymer sarudzo.
3. Door uye Window Profiles
PVC chinhu chakakurumbira chekuburitsa anoenderera mberi gonhi nemahwindo mafuremu, ayo ari akanakira kushandiswa kwemhuri.
4. Mapofu
Thermoplastics inogona kukwidziridzwa kuti igadzire yunifomu slats yemapofu, kazhinji ichishandisa polystyrene yekuonekwa kwehuni.
5. Weather Stripping
Rubber mamiriro ekunze ekubvisa zvigadzirwa zvinowanzowedzeredzwa, zvichipa zvinobudirira zvekuisa chisimbiso kune akasiyana maapplication.
6. Windshield Wipers uye Squeegees
Mawipers emota dzemotokari uye mabhureki squeegee blades anowanzo gadzirwa kubva kuextruded synthetic rubber materials seEPDM.
Iko kuita kwakasiyana-siyana uye kugona kwe extrusion molding inoita kuti ive ibwe repakona muindasitiri yekugadzira mapurasitiki, ine huwandu hwakawanda hwekushandisa uye mabhenefiti anotyaira kushandiswa kwayo kwakapararira.
