Matambudziko angangoitika muSMC molding process ndeaya: blistering uye kuputika kwemukati pamusoro pechigadzirwa;warpage uye deformation yechigadzirwa;anotsemuka muchigadzirwa mushure menguva yenguva, uye chikamu chefiber kuratidzwa kwechigadzirwa.Zvikonzero zvezviitiko zvine hukama uye matanho ekurasa ndeaya anotevera:
1. Kupupa pamusoro kana kuputira mukati mechigadzirwa
Chikonzero chechiitiko ichi chinogona kunge chiri chekuti zvinyorwa zvehunyoro uye zvinhu zvinoputika muzvinhu zvakanyanyisa;iyo mold tembiricha yakanyanya kana kuderera;kudzvinyirira hakuna kukwana uye nguva yekubata ipfupi;kupisa kwezvinhu hazvina kuenzana Kuenzana.Mhinduro ndeyekunyatso kudzora iyo inovhuvhuta yemukati mune izvo zvinhu, zvakakodzera kugadzirisa tembiricha ye mold, uye zvine musoro kudzora kuumbwa kwekumanikidza uye kubata nguva.Kuvandudza mudziyo wekudziya kuitira kuti zvinhu zvidziye zvakaenzana.
2. Chigadzirwa deformation uye warpage
Ichi chiitiko chinogona kukonzerwa nekurapa kusina kukwana kweFRP / SMC, kuderera kwekushisa kwekuumbwa uye nguva isina kukwana yekubata;kusaenzana ukobvu hwechigadzirwa, zvichikonzera kusaenzana shrinkage.
Mhinduro ndeyekunyatso kudzora tembiricha yekurapa uye kubata nguva;sarudza chinhu chakaumbwa nediki shrinkage rate;pasi pechikonzero chekusangana nezvinodiwa zvechigadzirwa, chimiro chechigadzirwa chinoshandurwa nenzira kwayo kuita kuti ukobvu hwechigadzirwa huve yunifomu sezvinobvira kana shanduko yakatsetseka.
3. Mitswe
Ichi chiitiko chinowanzoitika muzvigadzirwa zvine zvinoiswa.Chikonzero chingava.Chimiro chekuisa muchigadzirwa hachina musoro;nhamba yekuisa yakawandisa;iyo nzira yedemoulding haina musoro, uye ukobvu hwechikamu chimwe nechimwe chechigadzirwa chakasiyana zvakanyanya.Mhinduro ndeyekushandura chimiro chechigadzirwa pasi pemamiriro akabvumirwa, uye kuiswa kunofanira kusangana nezvinodiwa zvekuumba;gadzira zvine musoro nzira yekudzikisa kuti ive nechokwadi cheavhareji ejection simba.
4. Chigadzirwa chacho chiri pasi pekumanikidzwa, kushayikwa kwenzvimbo yeglue
Chikonzero chechiitiko ichi chingave chisina kukwana kudzvinyirira;yakawandisa fluidity yezvinhu uye kusakwana kwekudya kwehuwandu;yakanyanya tembiricha, zvekuti chikamu chechinhu chakaumbwa chinosimba nguva isati yakwana.
Mhinduro ndeyekunyatso kudzora tembiricha yekuumbwa, kudzvanywa uye kudzvanya nguva;chengetedza zvinhu zvakakwana uye hapana kushaikwa kwezvinhu.
5. Product sticking mold
Dzimwe nguva chigadzirwa chinonamatira kune mold uye hazvisi nyore kusunungura, izvo zvinokuvadza zvakanyanya kuonekwa kwechigadzirwa.Chikonzero chinogona kunge chiri chekuti iyo yemukati yekuburitsa mumiriri inoshaikwa mune izvo zvinhu;iyo mold haina kucheneswa uye mumiriri wekusunungura anokanganwa;pamusoro pe mold yakakuvadzwa.Mhinduro ndeyekunyatso kudzora kunaka kwezvinhu, kunyatsoshanda, uye kugadzirisa kukuvadzwa kwe mold munguva yekuzadzisa inodiwa mold kupera.
6. Mupendero wemarara wechigadzirwa wakanyanyisa
Chikonzero chechiitiko ichi chingave chisina musoro kugadzira mold;yakawandisa zvinhu zvakawedzerwa, nezvimwe. Mhinduro ndeyekuita inonzwisisika mold dhizaini;nyatso kudzora huwandu hwekudya.
7. Saizi yechigadzirwa haina kukodzera
Chikonzero chechiitiko ichi chinogona kunge chiri chekuti mhando yezvinhu haina kuzadzisa zvinodiwa;kudyisa hakusi kwakasimba;mold yakasakara;iyo mold design size haina kururama, etc. Mhinduro ndeyekunyatso kudzora kunaka kwezvinhu uye kunyatsodyisa zvinhu.Ukuru hwekugadzira mold hunofanira kunge hwakarurama.Zviumbwa zvakakuvadzwa hazvifanirwe kushandiswa.
Matambudziko ezvigadzirwa panguva yekuumba maitiro haangogumiri pane zviri pamusoro.Mukuita kwekugadzira, pfupikisa ruzivo, kuenderera mberi kwekuvandudza, uye kunatsiridza mhando.
