The theSMC Manyorero Kuumbwa Maitirondiyo inonyanya kushanda mune girazi fiber yakasimbiswa epurasitiki / midziyo yekuumbwa kuumbwa. Iyo SMC Molding maitiro ane zvakawanda zvakanakira, zvakadai seyakagadzirwa nechigadzirwa, kutaridzika kwechigadzirwa chechigadzirwa, kuita kwakashata kuchaonekwa mune yeSMC kuumbwa maitiro, iyo inonyanya kuratidzwa mune zvinotevera zvikonzero:
(I)Kushaikwa kwezvinhu.
(a) kushoma kwezvinhu zvinobuda
(b) Smc zvinyorwa zvine tsvina isina kunaka
(C) isina kukwana midziyo kumanikidzwa
(d) kurapa nekukurumidza
Chizvarwa cheChiera uye Zvematanho:
①ASTER iyo SMC zvinyorwa zvinoshandiswa nekupisa, iyo yekunyungudika viscossity yakakura. Pamberi pekubatanidza uye kusimbisa kuita kwapera, hapana nguva yakakwana, kudzvinyirira, uye vhoriyamu kuzadza iyo mold cavity ine chinyungudike.
②) Nguva yekuchengetedza yeiyo SMC yekuumba zvinhu zvakanyanyisa, uye iyo styrene inowedzera zvakawandisa, zvichikonzera kuderera kwakakura muzvinhu zvinoyerera zveSMC kuumbwa zvinhu.
③Toin pasita haina kunyudzwa mu fiber. Iyo resin paste haigoni kutyaira fiber kuti ifambe panguva yekuumbwa, zvichikonzera kuperevedza kwezvinhu. Kune kuperevedza kwezvinhu zvakakonzerwa nezvikonzero zviri pamusoro, mhinduro yakanyanya kutaurwa ndeyekubvisa izvi zvakaumbwa kana kucheka zvinhu.
④inguffication yekudya mari inokonzera kushomeka kwezvinhu. Mhinduro yacho ndeyekuwedzera mari yekudyisa nenzira kwayo.
⑤The mhepo yakawandisa uye yakawanda yechokwadi nyaya muzvinhu zvinoumbwa. Mhinduro ndeyekuwedzera zvakaringana huwandu hwekupfeka; Nenzira yakakodzera inowedzera nzvimbo yekudyisa uye burp kwenguva yakati yenguva yekuchenesa chiumbwa; zvakakodzera kuwedzera kudzvinyirira kudzvinyirira.
Dzvinyiriro yakanonoka, uye zvinhu zvakaumbwa zvakapedza kuyambuka-kuporesa uye kuporesa usati wazadza chando. ⑦Kana tembiricha yakakwirira yakanyanya, kuunganidza uye kuporesa maitiro anoenderera mberi, saka tembiricha inofanira kudzikiswa nenzira kwayo.
(2)Stoma.Iko kune nguva dzose kana zvisingaiti zvidiki maburi pamusoro pechigadzirwa, kazhinji zvacho zvinogadzirwa kumusoro uye epakati matete emadziro echigadzirwa.
Chizvarwa cheChiera uye Zvematanho:
①THE STMCal Kuumbwa Kwemhepo ine mhepo yakakura uye zvirimo zvakashata zvakakura, uye kuneta hakusi zvakanaka; Iko kukonzeresa mhedzisiro yeiyo smc zvinyorwa haina kunaka, uye gasi harigone kudzingwa. Izvo zviri pamusoro zvinokonzeresa zvinokonzerwa nekukanganiswa nekubatanidzwa kwekuwedzera huwandu hwemasendi uye kuchenesa mold.
②Te yekudyisa nzvimbo yakakura kwazvo, nenzira yakakodzera kuderedza nzvimbo yekudyisa inogona kudzorwa. Mukuita chaiko kwekuvhiya, zvinhu zvevanhu zvinogona kukonzerawo trachoma. Semuenzaniso, kana templeurization ichitomboitika, zvingave zvakaoma kuti gasi rakaputirwa mukuumbwa kwekuumbwa kuti riwedzerwe, zvichikonzera kuremara kwakadai kwemapures pamusoro pechigadzirwa.
(3)Warpage uye deformation. Chikonzero chikuru ndechekusarava kwekunyora kwekuumbwa uye kuderera kwechigadzirwa mushure mekudengenyeka.
Chizvarwa cheChiera uye Zvematanho:
Munguva yekuporesa maitiro eiyo resin, iyo makemikari zvigadzirwa shanduko, zvichikonzera vhoriyamu shrúgege. Kufanana kwekurapa kunoita kuti chigadzirwa chiwedzere kurwirira kune yekutanga kurapwa. Kechipiri, iyo yekuwedzera yekuwedzera inoenderana nechigadzirwa yakakura kupfuura iyo yeiyo simbi yekuumbwa. Kana chigadzirwa chacho chikatonhorera, iyo imwe-nzira inodzvinyirira chiyero yakakura kupfuura iyo nzira yekupisa-kupisa inoderera yeiyo mold. Kuti izvi zviitike, nzira dzinotevera dzinogamuchirwa kugadzirisa dambudziko:
①Rerece mutsauko wekupisa uripo pakati peiyo yepamusoro uye yakadzika molds, uye ita tembiricha yekugovera sezvinobvira;
②use kutonhora kudzikisira kudzikamisa kushomeka;
Iintly Wedzera kumanikidzwa kwekuumba, wedzera kuomarara kwechigadzirwa, uye kuderedza iyo shrinkage mwero wechigadzirwa;
④ Inomira nguva yekuchengetedza yekuchengetedza nenzira kwayo kukodzera kubvisa kushushikana kwemukati.
⑤ADINT iyo kurapa kuderera kwehuremu hwe smc zvinyorwa.
(4)Kupunzika.Iyo semicircular bulge pamusoro pechinhu chakarapwa chigadzirwa.
Chizvarwa cheChiera uye Zvematanho:
Zvingave kuti zvinyorwa zvinokombeswa, tembiricha yemuno yakanyanya, kana zvirimo zvakashata mune zvakakura, uye zvisungo zvemhepo zviri pakati pemashiti, izvo zvinoita simicircular bulge pamusoro pechigadzirwa.
(①Kunowedzera kumanikidzwa kwekuumba
(②xboxt nguva yekudzivirira yekuchengetedza
(③) Deredza tembiricha yemukati.
④Denda nzvimbo isingazivikanwe
(5)Ruvara rwemusoro rwechigadzirwa haruna kuenzana
Chizvarwa cheChiera uye Zvematanho:
①Tembiricha yakadzika haina kufanana, uye chikamu chakanyanya kwazvo. Iyo mold tembiricha inofanira kudzorwa zvakanaka;
②Poor Fluidity yezvinyorwa zvekuumba, zvichikonzera kugovera zvisina kufanira fiber kugovera, kazhinji kunogona kuwedzera kumanikidza kuumbwa kuti uwedzere kutsauswa kweiyo nyungudika;
③pigment uye resin haigone kusanganiswa zvakanaka mune iyo nzira yevara reruvara paste kusanganisa.
