Rubber Molding Injection Molding yeRubber Zvigadzirwa
Custom Injection Yakaumbwa Zvigadzirwa
Compression Molding
Mukumanikidza kuumbwa, musanganiswa werabha unopinzwa mugomba reforoma, uye kudzvanywa kunoiswa kudzvanya zvinhu muchimiro chaunoda. Kupisa kunobva kwashandiswa kurapa rabha. Iyi nzira inowanzo shandiswa kugadzira zvigadzirwa senge gaskets, zvisimbiso, uye zvinhu zvemotokari.
Jekiseni Molding
Jekiseni rekugadzira rinosanganisira kubaya jekiseni rabha yakanyungudutswa muforoma pasi pekumanikidzwa kukuru. Maitiro aya akanakira kugadzira zvakaomarara uye chaizvo zvikamu, zvinosanganisira zvinhu zvemotokari uye zvinhu zvevatengi. Overmolding uye kuisa molding mutsauko wekuita uku, zvinosanganisira kubatanidzwa kwezvikamu zvesimbi zvakapedzwa mugomba rekuumbwa usati wabaya jekiseni rabha.
Transfer Molding
Kubatanidza zvinhu zvekumanikidza uye jekiseni kuumba, kutamisa kuumbwa kunoshandisa yakayerwa huwandu hwerabha mukamuri inopisa. Plunger inomanikidza zvinhu kuita mugomba, zvichiita kuti ive yakakodzera kugadzira magetsi ekubatanidza, grommets, uye zvikamu zvidiki chaizvo.
Extrusion
Extrusion inoshandiswa kugadzira inoenderera kureba yerabha ine chaiwo-muchinjika-chikamu maumbirwo, senge hose, tubing, uye profiles. Iyo rabha inomanikidzwa kuburikidza nefa kuti iwane inodiwa kugadzirisa.
Kurapa (Vulcanization)
Kurapa, kana vulcanization, kunosanganisira kuyambuka-kubatanidza macheni erabha epolymer kuwedzera simba, elasticity, uye kudzivirira kupisa. Izvi zvinowanikwa kuburikidza nekushandiswa kwekupisa uye kudzvanywa kune yakaumbwa rabha chigadzirwa, ine nzira dzakajairwa dzinosanganisira chiutsi, mhepo inopisa, uye microwave kurapwa.
Rubber kune Metal Bonding
A specialized process, rabha kusvika kusimbi bonding inogadzira zvigadzirwa zvinobatanidza kuchinjika kwerabha nekusimba kwesimbi. Chikamu cherabha chakafanoumbwa kana kuumbwa, chinomisikidzwa pamusoro pesimbi nenamira, uye chobva chaiswa mukupisa uye kumanikidzwa kwevulcanization kana kurapa. Iyi maitiro emakemikari anosunga rabha kusimbi, ichigadzira yakasimba uye yakasimba yekubatanidza yakakosha kune maapplication anoda zvese kudonhedza kunyorova uye kutsigirwa kwechimiro.
Compounding
Kusanganisa kunosanganisira kusanganisa mbishi zvinhu zverabha nezvimwe zvakasiyana-siyana kuti ugadzire musanganiswa werabha une zvinhu chaizvo. Zvinowedzera zvinogona kusanganisira kurapa vamiririri, accelerators, antioxidants, fillers, plasticizers, uye colorants. Kusanganiswa uku kunowanzoitwa muchigayo-maviri kana musanganisi wemukati kuti ive nechokwadi chekugoverwa kweyunifomu yezvinowedzera.
Kugaya
Kutevera kusanganiswa, musanganiswa werabha unopinda mukugaya kana kusanganisa maitiro kuti uwedzere homogenize uye kugadzira zvinhu. Iyi nhanho inobvisa mabhuru emhepo uye inovimbisa kufanana mukomboni.
Post-Processing
Mushure mekurapa, chigadzirwa cherabha chinogona kuita mamwe maitiro, anosanganisira kudimburisa, kudzima (kubvisa zvinhu zvakawandisa), uye kurapwa kwepamusoro (sekuposhera kana kupukuta) kuzadzisa zvinodiwa.
Kushandiswa kweRubber Molding chikamu
Rubber Molding Materials
Mhando yega yega yerabha ine seti yakasiyana yezvivakwa, zvichiita kuti ive yakakodzera kune chaiwo maapplication. Kusarudzwa kwezvinhu zverabha kunotsamira pazvinhu zvakaita sezvinodiwa kushandiswa, mamiriro ekunze, tembiricha, kuratidzwa kwemakemikari, uye hunhu hunodiwa hwemuviri.
Heano mamwe marudzi ekutanga erabha:
Natural Rubber (NR):
Yakatorwa kubva kune latex sap yemuti werabha (Hevea brasiliensis), rabha yechisikigo inozivikanwa nekudzika kwayo uye kusimba. Inowanzo shandiswa mukushandisa senge matai, shangu, uye zvigadzirwa zvevatengi, ine kushomeka kwekupokana nekupisa nemakemikari.
Synthetic Rubber:
Yakagadzirwa nemaitiro kuburikidza nemakemikari maitiro, synthetic rubbers inopa huwandu hwakawanda hwezvivakwa. Mamwe marudzi akajairika anosanganisira:
Styrene-Butadiene Rubber (SBR)
Inoshandiswa zvakanyanya kune yakanakisa abrasion kuramba uye kusimba, kazhinji inowanikwa mumatayi emotokari uye mabhandi ekutakura.
Polybutadiene Rubber (BR):
Inokosheswa kusimba kwepamusoro uye kudzika-kudzikama kuchinjika, kunowanzo shandiswa mukugadzira matayi uye sechinhu chinogadziridza mumapurasitiki.
Nitrile Rubber (NBR):
Inoratidza kupikisa kwakasarudzika kuoiri, mafuta, uye makemikari, zvichiita kuti ive yakakodzera zvisimbiso, gaskets, uye O-mhete muzvikamu zvemotokari nemaindasitiri.
Butyl Rubber (IIR):
Inozivikanwa nekusapinda mumagasi, yakanakira matayi emukati machubhu, machira emukati ematangi ekuchengetera makemikari, uye zvimiso zvemishonga.
Neoprene (CR):
Inopa kupikisa kwakanyanya kumamiriro ekunze, ozone, uye oiri, sarudzo yakakurumbira yewetsuits, hoses, uye magasi emotokari.
Ethylene Propylene Diene Monomer (EPDM):
Inokosheswa kurwisa kupisa, mamiriro ekunze, uye UV mwaranzi, inowanzoshandiswa mumatenga ematenga, zvisimbiso zvemotokari, uye kunze kwemagetsi ekudzivirira.
Silicone Rubber (VMQ):
Inozivikanwa nekunaka kwekudzivirira kupisa uye magetsi ekudzivirira zvivakwa, anowanzo shandiswa mumidziyo yekurapa, cookware, mota dzekushandisa, uye sealant.
Fluoroelastomers (FKM):
Inopikisa zvakanyanya kumakemikari, tembiricha yakakwira, uye oiri, anowanzo shandiswa mumashandisirwo anoda kusarudzika makemikari kuramba, sezvisimbiso uye gaskets mumaindasitiri emakemikari uye aerospace.
Chloroprene Rubber (CR):
Iyo inozivikanwawo seNeoprene, inopa kuramba kwakanaka kumamiriro ekunze uye ozone. Inowanzo shandiswa mumashandisirwo anoda kuenzana kwezvinhu zvemuviri, senge wetsuits uye bhandi remaindasitiri.
Polyurethane (PU):
Kubatanidza zvimiro zverabha nepurasitiki, polyurethane rabha inokosheswa nekuda kweabrasion kuramba uye kutakura mutoro. Inowanzoshandiswa mumavhiri, bushings, uye maindasitiri emuchina zvikamu.
