Kuita kwezvinhu
Corrosion resistance, magetsi ekudzivirira (kunyanya high frequency insulation) yakanakisa, inogona kuve chlorinated, irradiation yakagadziridzwa, inowanikwa girazi fiber yakasimbiswa.Low pressure polyethylene ine high melting point, rigidity, kuoma uye kusimba, kunyura kwemvura kuderera, kunaka kwemagetsi zvivakwa uye neradiation resistance;high pressure polyethylene ine yakanaka kuchinjika, kureba, simba rekuita uye permeability;Ultra-yakakwirira molecular uremu polyethylene ine yakakwirira simba simba, kuneta kuramba uye kupfeka kuramba.
Low pressure polyethylene inokodzera kugadzira corrosion resistant parts and insulating parts;high pressure polyethylene yakakodzera kugadzira mafirimu, nezvimwewo;UHMWPE yakakodzera kugadzira kuvhunduka, kupfeka kusagadzika uye kutapurirana zvikamu.
Molding performance
1, Crystalline zvinhu, kunyura kudiki kunyura, hazvidi kuoma zvakakwana, zvakanakisa fluidity, fluidity inonzwa kumanikidzwa.High-pressure jekiseni inokodzera kuumba, yunifomu tembiricha yezvinhu, kukurumidza kuzadza kukurumidza uye yakakwana yekumanikidza-inobata.Hazvina kukodzera kushandisa gating yakananga kudzivirira kusaenzana shrinkage uye kuwedzera kwekunetseka kwemukati.Nyatsoteerera kusarudzwa kwegedhi nzvimbo kudzivirira shrinkage uye deformation.
2, Shrinkage renji uye shrinkage kukosha kwakakura, gwara riri pachena, nyore deformation uye warpage.Iko kumhanya kwekutonhora kunofanirwa kunonoka, uye mold inofanira kunge iine mavhu anotonhora uye inotonhorera system.
3, Nguva yekupisa haifanire kunge yakareba, zvikasadaro kuora kuchaitika nekupisa.
4, Kana zvikamu zvepurasitiki zvakapfava zviine mativi asina kudzika, mold inogona kumanikidzwa kubva.
5, Kuputika kwekunyunguduka kunogona kuitika uye hakufanirwe kunge kwakabatana neorganic solvents kudzivirira kutsemuka.

2, Yakanaka fusion ine 372 organic girazi, yakagadzirwa maviri-mavara epurasitiki zvikamu, uye pamusoro anogona kuve chrome-plated, pfapfaidzo pendi kurapwa.
3, kune yakakwira kukanganisa, kupisa kwakanyanya kuramba, kudzoreredza murazvo, kukwidziridzwa, kujeka uye mamwe mazinga.
4, fluidity yakashata zvishoma pane HIPS, iri nani pane PMMA, PC, nezvimwewo, yakanaka kuchinjika.
Inokodzera kugadzira zvakajairika mamechani zvikamu, zvipfeko zvinodzivirira kupfeka, zvikamu zvekutumira uye zvikamu zvekufonera.
Molding performance
1, amorphous zvinhu, yepakati fluidity, kunyorova kwemwando, kunofanirwa kuomeswa zvizere, izvo zvinodikanwa zvepasi pezvikamu zvepurasitiki zvinopenya zvinofanirwa kunge zviri nguva yakareba preheat kuomesa 80-90 madhigirii, maawa matatu.
2, Zvinokurudzirwa kutora tembiricha yemhando yepamusoro uye tembiricha yakakwira mold, asi tembiricha yezvinhu yakakwira zvakanyanya uye iri nyore kuora.Kune yakakwirira chaiyo yezvikamu zvepurasitiki, tembiricha yekuumbwa inofanirwa kunge iri 50-60 madhigirii, uye kune yakakwira gloss isingadziviriri epurasitiki zvikamu, tembiricha yekuumbwa inofanira kunge iri 60-80 madhigirii.
3, Kana iwe uchida kugadzirisa dambudziko remvura clamping, unofanirwa kuvandudza fluidity yezvinhu, tora tembiricha yepamusoro, tembiricha yepamusoro yekuumbwa, kana kushandura mwero wemvura uye dzimwe nzira.
4, senge kugadzira giredhi isingadziviriri kana moto-inodzoreredza giredhi zvinhu, iyo mold mushure memazuva 3-7 ekugadzirwa icharamba yakaora epurasitiki, zvichikonzera kuti mold inopenya, mold inoda kucheneswa nenguva. nepo mold surface inoda kuwedzera nzvimbo yekupedza.

Material properties
Diki density, simba, kuomarara, kuomarara uye kupisa kupisa zviri nani pane yakaderera pressure polyethylene, inogona kushandiswa paanenge 100 madhigirii.Yakanaka magetsi emagetsi uye yakakwirira-frequency insulation haina kukanganiswa nehunyoro, asi inova brittle pakudziya kwakadzika uye haina kupikisa mold uye nyore kuchembera.
Yakakodzera kugadzira general mechanical parts, corrosion resistant parts uye insulating parts.
Molding performance
1, crystalline zvinhu, kunwisa hunyoro kudiki, nyore kunyungudutsa kuputika kwemuviri, kugarisana kwenguva refu nesimbi inopisa nyore kuora.
2, yakanaka fluidity, asi shrinkage siyana uye shrinkage kukosha yakakura, nyore kuitika shrinkage, kubono, deformation.
3, Fast kutonhora kumhanya, kudira sisitimu uye kutonhora sisitimu inofanira kunonoka kudzima kupisa, uye teerera kudzora tembiricha yekuumba.Kutungamira kwekushisa kwezvinhu zvakaderera kuri pachena, kunyanya pakupisa kwakadzika uye kudzvinyirira kwakanyanya.Kana tembiricha yeforoma yakadzikira kupfuura madhigirii makumi mashanu, zvikamu zvepurasitiki hazvina kutsvedzerera, zviri nyore kugadzira kusanganisa kwakashata, kusiya mamakisi, uye pamusoro pe90 madhigirii, nyore kuchinjika uye deformation.
4, iyo yepurasitiki madziro ukobvu hunofanirwa kunge hwakafanana, kudzivirira kushaikwa kweglue, makona akapinza, kudzivirira kushushikana.

Kuita kwezvinhu
Kuiswa kwemagetsi (kunyanya yakakwira frequency insulation) yakanakisa, isina ruvara uye yakajeka, mwenje wekutapurirana mwero ndeyechipiri kune organic girazi, mavara, kuramba mvura, kugadzikana kwemakemikari kwakanaka.General simba, asi brittle, nyore kugadzira kushushikana brittle crack, isingamirire benzene, peturu uye zvimwe organic zvinonyungudutsa.
Inokodzera kugadzira insulating uye yakajeka zvikamu, zvekushongedza zvikamu uye zvikamu zvemakemikari zviridzwa uye optical zviridzwa.
Kugadzira kuita
1, amorphous material, kunyura kuduku, haifaniri kuoma zvakakwana, kwete nyore kuora, asi iyo coefficient yekuwedzera kwekushisa yakakura, iri nyore kuburitsa kushushikana kwemukati.Kuyerera kwakanaka, kunowanikwa screw kana plunger jekiseni muchina kuumba.
2, Tembiricha yepamusoro, tembiricha yakakwira mold uye yakaderera jekiseni kudzvanywa kwakakodzera.Kuwedzera nguva yejekiseni kunobatsira kuderedza kushushikana kwemukati uye kudzivirira shrinkage uye deformation.
3, inowanikwa mumhando dzakasiyana dzegedhi, gedhi uye epurasitiki arc yekubatanidza, kuitira kudzivirira kukuvadzwa kwezvikamu zvepurasitiki paunenge uchienda kugedhi.Iyo yakatsetseka yedemoulding yakakura, iyo ejection yakaenzana, madziro emadziro echikamu chepurasitiki chakaenzana, zviri nani kuti usava nekuisa, kana paine kuiswa, ivo vanofanirwa kuve preheated.
