FOAM Industry Information |Kekutanga muChina!FAW Audi yakachena yemagetsi emukati zvikamu zvinoshandisa micro-foaming maitiro kuderedza uremu uye kugara kwenguva refu

Sezvo kufarirwa kwemusika mutsva wemotokari yemagetsi kuri kuramba kuchikwira, rwendo rwekufamba rwakagamuchirawo kutariswa kwakanyanya kubva kune indasitiri ketani.Nekuenderera mberi kwekuvandudza tekinoroji yebhatiri, dhizaini yakareruka iyo inogona kudzikamisa iyi kudzvanywa padanho rekugadzira zvishoma nezvishoma yave yakakosha label yemota nyowani.Sosaiti yeMotokari Engineers yeChina yakataura mu "Technical Roadmap 2.0 yeMagetsi Ekuchengetedza uye New Energy Vehicles" kuti zvinotarisirwa kuti panosvika 2035, iyo yakareruka coefficient yemagetsi akachena emotokari dzinotakura vanhu ichaderedzwa ne35%.

Parizvino, matekinoroji anotevera akabuda mundima yakareruka yemotokari isiri-simbi zvinhu: micro-foaming uremu hwekudzikisa tekinoroji, mutete-walled kudzikisa uremu tekinoroji, yakaderera-density kudzikisa uremu hwezvinhu tekinoroji, kabhoni fiber yakasimbisa zvinhu tekinoroji, biodegradable zvinhu tekinoroji. , nezvimwewo.

Ngatitarisei kuti mapurasitiki anogona sei kuderedza huremu hwemotokari maererano neiyo micro-foam jekiseni rekugadzira tekinoroji?

Chii chinonzi Microfoam Injection Molding?

Micro-foaming jekiseni kuumba inotsiva kudzvanywa kwejekiseni rekugadzira muchina kuburikidza nekuwedzera masero, haidi yakawandisa yekuzadza kumanikidza, uye inogona kuita yekumanikidza kugovera yunifomu kuburikidza nesero chimiro cheyepakati layer kuderedza density yechigadzirwa uye kuwana controllable foaming rate Kuti uderedze uremu hwechigadzirwa, iyo cavity pressure inoderedzwa ne30% -80%, uye kushushikana kwemukati kunoderera zvakanyanya.

Maitiro eiyo micro-foaming jekiseni molding process iri nyore.Chekutanga, zvinodikanwa kunyungudutsa iyo supercritical fluid musol yepurasitiki main material, uye wobva wapfapfaidza iyo yakasanganiswa sol zvinhu muforoma kuburikidza ne-high-pressure jekiseni mudziyo kugadzira micro-foaming.Zvino, sezvo kudzvanywa uye tembiricha mu mold inodzikama, ma microbubbles ari mu mold ari mune yakagadzikana mamiriro.Nenzira iyi, iyo jekiseni molding process inopedzwa.
