Nthawi Yofunika Yopangira Silicone Mold

Nthawi Yofunika Yopangira Silicone Mold
Kuumba silicone ndi njira yosinthasintha komanso yothandiza yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana popanga zinthu zapamwamba kwambiri zokhala ndi tsatanetsatane wovuta. Nthawi yomwe imafunika popanga silicone mold ingakhudzidwe ndi zinthu zingapo, kuphatikizapo mtundu wa silicone yomwe imagwiritsidwa ntchito, zovuta za kapangidwe kake, ndi njira yeniyeni youmba yomwe imagwiritsidwa ntchito. Mu positi iyi ya blog, tifufuza njira zosiyanasiyana zoumba silicone ndi nthawi yomwe aliyense ayenera kuganizira.

Kuumba Silikoni Yotentha Kwambiri (HTV)
Kutulutsa mpweya wotentha kwambiri (HTV) ndi njira yomwe imagwiritsidwa ntchito popanga ma rabara a silicone amphamvu kwambiri oyenera kugwiritsidwa ntchito m'mafakitale. Njirayi imachitika pogwiritsa ntchito makina otenthetsera ndipo nthawi zambiri imatenga mphindi zingapo kuti itsirize kutulutsa mpweya wotentha. Nthawi yofulumira yoyeretsa mpweya wa HTV imapangitsa kuti ikhale chisankho chabwino kwambiri pakupanga zinthu mwachangu.

Kutentha kwa Chipinda Vulcanization (RTV) Silicone Molding
Kutulutsa mpweya wotentha m'chipinda (RTV) ndi njira yocheperako poyerekeza ndi HTV, pogwiritsa ntchito chothandizira cha platinum chomwe chimatenga maola pafupifupi 24 kuti chiume ndikupanga zinthu zofewa komanso zofewa za silicone. Njirayi ndi yoyenera kugwiritsidwa ntchito pamene pakufunika kusinthasintha ndi kufewa.

Njira Yopangira Silicone Transfer
Kuumba silicone ndi njira yolondola kwambiri yomwe imapereka nthawi yozungulira mwachangu poyerekeza ndi njira zina zopangira. Imamaliza kuzungulira pafupifupi masekondi 30-45, komwe kumakhala kofulumira kwambiri kuposa kupanga compression, komwe kumatenga pafupifupi mphindi 2-3 pa kuzungulira. Kuchita bwino kwa silicone transfer molding kumachokera ku kapangidwe kake kapadera kosindikizira ndi pre-form, komwe kumachepetsa kwambiri nthawi yozungulira.

Kuyerekeza ndi Njira Zina Zopangira Ubweya
Kupangira jakisoni: Kuumba kwa silicone kumagwira ntchito pamavuto otsika (1,500-2,500 PSI) poyerekeza ndi kupanga jakisoni (10,000-30,000 PSI), zomwe zimapangitsa kuti zida zisawonongeke kwambiri ndipo zimakhala bwino pazinthu zomwe zimakhudzidwa ndi kuthamanga kwambiri.

Kuumba Nkhonya: Kuumba silicone kusamutsa kumasiyana ndi kupanga blowing pogwiritsa ntchito makina a chipinda kusamutsa silicone yotenthedwa kale mu nkhungu, zomwe zimapangitsa kuti ikhale yoyenera pazinthu zatsatanetsatane komanso zolondola kwambiri.

Kuumba Kozungulira: Ngakhale kuti kuumba kozungulira kumazungulira nkhungu kuti igawire zinthu mofanana, kuumba kwa silicone kumagwiritsa ntchito mphamvu kuti ikankhire zinthu zomwe zatenthedwa kale mu nkhungu, zomwe zimapangitsa kuti zikhale zolondola kwambiri komanso nthawi yozungulira ipite mwachangu.

Kukonza kutentha: Kuumba kwa silicone ndikoyenera magawo a 3D okhala ndi tsatanetsatane wovuta, mosiyana ndi thermoforming, yomwe imatenthetsa pepala la pulasitiki ndikulipanga pamwamba pa nkhungu.

Kutulutsa Zinthu Zofunika: Kuumba kwa silicone kumapanga zigawo za 3D, pomwe kupanga kwa extrusion kumapanga mawonekedwe aatali komanso opitilira a 2D

Kuumba Kakang'ono: Kuumba kwa silicone kusamutsa kumagwirira ntchito zigawo zazikulu ndipo kumathamanga, zomwe zimapangitsa kuti zikhale zabwino kwambiri popanga zinthu zambiri, mosiyana ndi kupanga zinthu zazing'ono, zomwe zimagwira ntchito m'zigawo zazing'ono.

Kukonza Jakisoni (RIM): Mosiyana ndi RIM, yomwe imadalira momwe mankhwala amagwirira ntchito popanga ziwalo, silicone transfer molding imatenthetsa silicone yooneka ngati mawonekedwe ndikuyikankhira mu nkhungu, zomwe zimapangitsa kuti mphamvu, tsatanetsatane, ndi liwiro la kupanga zisinthe.

Mapeto
Nthawi yofunikira popanga chikombole cha silicone imadalira njira ndi kagwiritsidwe ntchito kake. Kukonza chikombole cha silicone, makamaka, kumapereka njira yachangu komanso yothandiza yopangira zida za silicone zolondola kwambiri. Kumvetsetsa kusiyana pakati pa njira zopangira chikombole cha silicone ndi nthawi yomwe zimafunikira kungathandize opanga kukonza njira zawo zopangira kuti zikhale zogwira mtima komanso zabwino.
