zvigadzirwa

HDPE Injection molding yekrete,
HDPE YeCrate, HDPE jekiseni kuumba,

Plastic crate inogadzirwa nehigh density polyethylene (HDPE) jekiseni rekutanga fusion.
Crate inoumbwa neyakakosha HDPE zvinhu kuti iwane kusimba kwakanyanya.Iko kunyunguduka kwezvinhu zvakakosha ndeye 3.6-4.5 g / 10 maminetsi, tension iri pamusoro pe25 Pa, simba rekugadzirisa rinopfuura 60% uye simba rekugadzirisa rinopfuura 40 Pa. Kazhinji HDPE zvinhu hazvina branching, asi chinhu chitsva chinokosha. inoshandiswa kumakrete inopa simba rakasimba remaintermolecular uye kusimba kwesimba kupfuura LDPE.Kumusoro kwayo kwakaoma uye kwakajeka, uye inokwanisa kumira tembiricha yepamusoro (120 C/248 F kwenguva pfupi, 110 C / 230 F nguva dzose), kuitira kuti isvike pazvinodiwa zvekusimba.Izvo zvinofanirwa kucherechedzwa kuti HDPE, kusiyana ne polypropylene, haigone kumirisana neiyo general high pressure.

Jekiseni Molding
Jekiseni molding ipurasitiki yekugadzira maitiro anosanganisira kubaya mapurasitiki akanyunguduka mbishi mukamuri yakavharwa kana mold.Iyi nzira ine maitiro makuru matatu:

Kukuya uye kupisa epurasitiki kusvikira ichiyerera pasi pekumanikidzwa.
Kupinza purasitiki mukati me mold uye kuibvumira kuti itonhore.
Kuvhura mold kuti ubvise chigadziko chepurasitiki.
A reciprocating screw type extruder inoshandiswa kunyanya muindasitiri yekugadzira mapurasitiki ekusanganiswa;kune kudzokororwa kusanganisa uye kukandwa kweiyo screw type extruder.Kana iyo plastiki (raw materials) yakagadzirira kujowa, sezvo screw inofamba, inosundira plastiki kunze kweextruder uye muforoma.

Kugadzira chimiro chinodiwa nemutengi, pane mold yakagadzirwa nechaiyo ine chimwe chimiro.Kazhinji ine zvikamu zviviri kana mahafu ane maitiro akafanana.Imwe inokwanisa kufamba kana kuti inoramba yakamira apo imwe chikamu che mold ichigona kufamba.Mushure mekuumbwa, imwe hafu inogona kufamba nekudaro kusunungura chigadzirwa kubva mukuumbwa mune undemented fomu.Iyo mold ine akati wandei kana akawanda mazaruro kana chiteshi.Aya anoshandiswa kupinza purasitiki muforoma, mhepo yekuvhuvhuta, uye kubvumira imwe plastiki kuti ibude kubva muforoma.

Jekiseni molding yakadzora kugadzirwa kana zvasvika pakugadzirwa kweimwe mativi midziyo kana makrete.Mabhabhu, mapairi, makapu, midziyo yezvokudya, uye mbiya mienzaniso.Nechega, jekiseni rekugadzira harina kukodzera kugadzira zvakavharika, maburi zvigadzirwa semabhodhoro epurasitiki ndosaka akakodzera kugadzirwa kwemakrete akavhurika.Kugadzira zvigadzirwa izvi, gasi inert inoshandiswa.Izvi zvinoshandiswa nekuti zvinobvisa maitiro anogona kupinda muforoma kana maitiro achifamba.Izvi zvinounzwa muforoma yakazadzwa zvishoma nepurasitiki yakanyungudutswa.Izvi zvinosaidzira purasitiki pamusoro pechiumbwa ichibudisa chikamu chisina mhango.Izvi zvinodaidzwa kuti gas-assisted injection molding.

Application

HDPE jekiseni-kuumbwa giredhi rinoshandiswa kugadzira midziyo inogona kushandiswazve, senge makesi edoro, makesi ezvinwiwa, makesi echikafu, makesi emuriwo nemakesi emazai uye anogona zvakare kushandiswa kugadzira matireyi epurasitiki, midziyo yemidziyo, midziyo yemumba, kushandiswa kwezvinhu zvemazuva ese uye zvitete- midziyo yezvokudya zvemadziro.Inogona zvakare kushandiswa mukugadzirwa kweindasitiri-yekushandisa madhiramu, mabhini emarara uye matoyi.Kuburikidza neextrusion uye compression molding process uye jekiseni kuumba, inogona kushandiswa kugadzira caps yemvura yakacheneswa, mineral water, tea chinwiwa uye juice mabhodhoro echinwiwa.
