Mukumanikidza kuumbwa, maviri anoenderana mold halves anoisirwa muchina (kazhinji hydraulic), uye kufamba kwavo kunogumira kune axis perpendicular kune ndege yemuumbi.Musanganiswa we resin, filler, inosimbisa zvinhu, kurapa mumiriri, nezvimwewo inotsikirirwa uye inoporeswa mune iyo mamiriro iyo inozadza mhango yese yekuumbwa kufa.Iyi nzira inowanzobatanidzwa nezvinhu zvakawanda, kusanganisira:
Epoxy resin prepreg inoenderera fiber
Sheet molding compound (SMC)
Dumpling modhi zvinhu (DMC)
Bulk Molding Compound (BMC)
Girazi mat thermoplastic (GMT)
Compression kuumba matanho
1. Kugadzirira kwekugadzira zvinhu
Kazhinji, zviumbwa zvehupfu kana granular zvinoiswa mugomba, asi kana huwandu hwekugadzira hwakakura, pretreatment inowanzobatsira.
2. Preheating yekugadzira zvinhu
Nekupisa zvinhu zvekuumba pamberi, chigadzirwa chakaumbwa chinogona kurapwa zvakafanana, uye kutenderera kutenderera kunogona kupfupikiswa.Mukuwedzera, sezvo kuumbwa kwekumanikidza kunogona kuderedzwa, kunewo mhedzisiro yekudzivirira kukuvadzwa kwekuisa uye mold.Kupisa kwemhepo kutenderera kudzvinyirirwa kunoshandiswawo preheating, asi yakakwirira frequency preheaters inoshandiswa zvakanyanya.
3. Kuumba kushanda
Mushure mokunge zvinhu zvekuumba zviiswa muhutu, zvinhu zvinotanga kunyoroveswa uye zvinoyerera zvakakwana pasi pekumanikidzwa kwakaderera.Mushure mekuneta, mold inovharwa uye inomanikidzwa zvakare kuti irape kwenguva yakatarwa.
Unsaturated polyester uye epoxy resins isingaburitse gasi haidi kupera.
Kana degassing ichidikanwa, nguva yekuronga inofanira kudzorwa.Kana nguva yacho isati yasvika, huwandu hwegasi hwakaburitswa hudiki, uye huwandu hukuru hwegasi huchavharwa muchigadzirwa, izvo zvinogona kuburitsa mabhubhu pamhepo yekuumba.Kana nguva yanonoka, gasi rakavharirwa mune chikamu chakaporeswa chigadzirwa, zvakaoma kutiza, uye zvinogona kukonzera kuputika muchigadzirwa chakaumbwa.
Kune zvigadzirwa zvakakora-madziro, nguva yekurapa ichave yakareba kwazvo, asi kana kurapwa kusati kwapera, mabhubhu anogona kugadzirwa panzvimbo yekuumba, uye zvigadzirwa zvakakanganisika zvinogona kugadzirwa nekuda kwedeformation kana post-shrinkage.
