Tsarin shimfiɗa hannu shine hanya mafi gargajiya don ƙirƙirar flanges na filastik mai ƙarfafa fiberglass (FRP). Wannan dabarar ta ƙunshi sanya resin da aka dasa da hannu.zane na fiberglassko kuma a sanya tabarmi a cikin wani tsari sannan a bar su su warke. Tsarin da aka tsara shi ne kamar haka: Da farko, ana ƙirƙirar wani layi mai cike da resin ta amfani da resin da fiberglass zane. Bayan layin layin ya warke, ana cire shi daga cikin tsari, sannan a gina layin tsari. Sannan a goge resin a saman mold da kuma layin ciki. Ana shimfida yadudduka na zane na fiberglass da aka riga aka yanke bisa ga tsarin da aka riga aka tsara, tare da matse kowane layi ta amfani da abin nadi don tabbatar da cewa an cika shi sosai. Da zarar an cimma kauri da ake so, ana tattara kayan kuma a rushe su.

Resin matrix don yin ƙera hannu yawanci yana amfani da epoxy ko polyester mara cika, yayin da kayan ƙarfafawa matsakaici ne ko alkaline.zane mai fiberglass mara alkali.

Fa'idodi: Ƙananan buƙatun kayan aiki, ikon samar da flanges marasa daidaito, kuma babu ƙuntatawa akan tsarin flange.

Rashin Amfani: Kumfa na iska da aka samu yayin da resin ke narkewa na iya haifar da porosity, rage ƙarfin injina; ƙarancin ingancin samarwa; da kuma rashin daidaituwa, rashin kyawun kammala saman.

2. Tsarin Matsi

Tsarin matsewa ya ƙunshi sanya adadin kayan gyaran da aka auna a cikin tsarin flange da kuma warkar da shi a ƙarƙashin matsin lamba ta amfani da matsewa. Kayan gyaran sun bambanta kuma suna iya haɗawa da haɗin zare mai gajere da aka riga aka haɗa ko aka riga aka haɗa, tarkacen zane na fiberglass da aka sake yin amfani da su, zoben zane/tsari na fiberglass mai layuka da yawa da aka haɗa da resin, zanen SMC (takardar gyaran takarda) da aka tara, ko kuma kayan gyaran zane na fiberglass da aka riga aka saka. A cikin wannan hanyar, ana ƙera faifan flange da wuya a lokaci guda, suna ƙara ƙarfin haɗin gwiwa da kuma daidaiton tsarin gabaɗaya.

Ribobi: Daidaito mai girma, maimaituwa, dacewa da samar da taro ta atomatik, ikon samar da flanges masu rikitarwa a mataki ɗaya, da kuma saman da ke da santsi wanda ba ya buƙatar gyara bayan an gama aiki.

Rashin Amfani: Kuɗin mold mai yawa da ƙuntatawa akan girman flange saboda ƙuntatawa na gadon latsawa.

3. Canja wurin Guduro (RTM)  

RTM ya ƙunshi sanya ƙarfin fiberglass a cikin wani abu da aka rufe, allurar resin don sanya zare a cikin ciki, da kuma warkarwa. Tsarin ya haɗa da:

• Sanya wani tsari na fiberglass wanda ya dace da yanayin flange a cikin ramin mold.
• A yi allurar resin mai ƙarancin ɗanko a ƙarƙashin yanayin zafi da matsin lamba da aka sarrafa don cika yanayin da aka riga aka tsara da kuma fitar da iska.
• Dumamawa don warkewa da kuma rushe flange ɗin da aka gama.

Resins yawanci polyester ne mara cikawa ko epoxy, yayin da ƙarfafawa sun haɗa databarmar fiberglass mai ci gabako masaku masu saƙa. Ana iya ƙara abubuwan cikawa kamar calcium carbonate, mica, ko aluminum hydroxide don haɓaka halaye ko rage farashi.

Fa'idodi: Sufuri masu santsi, yawan aiki, aiki mai rufewa (rage hayaki da haɗarin lafiya), daidaita zare a hanya don ingantaccen ƙarfi, ƙarancin jarin jari, da rage amfani da kayan aiki/makamashi.

4. Gyaran Canja wurin Resin Mai Taimakawa a Injin Vacuum (VARTM)

VARTM tana gyara RTM ta hanyar saka resin a ƙarƙashin injin tsabtace iska. Tsarin ya ƙunshi rufe murfin fiberglass a kan injin tsabtace iska na namiji da jakar injin tsabtace iska, da kuma fitar da iska daga ramin injin tsabtace iska, da kuma jawo resin cikin injin tsabtace iska ta hanyar matsi.

Idan aka kwatanta da RTM, VARTM tana samar da flanges masu ƙarancin porosity, yawan zare, da kuma ƙarfin injina mai kyau.

5. Gyaran juyi mai taimakawa wajen canza jakar iska

Ginawa ta hanyar amfani da jakar iska (RTM) wani nau'in fasahar ƙera kaya ne da aka haɓaka bisa ga RTM. Tsarin shirya flanges ta wannan hanyar ƙera kaya shine kamar haka: ana sanya preform na gilashi mai siffar flange a saman jakar iska, wanda aka cika da iska sannan ya faɗaɗa waje kuma an iyakance shi zuwa sararin cathode mold, kuma preform na flange tsakanin cathode mold da jakar iska an matse shi kuma an warke.

Ribobi: faɗaɗa jakar iska zai iya sa resin ya kwarara zuwa ɓangaren preform ɗin da ba a yi masa dashen ba, yana tabbatar da cewa resin ya yi dashen preform ɗin sosai; ana iya daidaita abun da ke cikin resin ta hanyar matsin jakar iska; matsin da jakar iska ke yi ana shafa shi a saman ciki na flange ɗin, kuma flange ɗin bayan an gama shafawa yana da ƙarancin porosity da kyawawan halayen injiniya. Gabaɗaya, bayan an shirya,Jam'iyyar FRPflange tare da hanyar ƙera da ke sama, ya kamata a sarrafa saman waje na flange ɗin bisa ga buƙatun amfani da juyawa da haƙa ramuka a kewayen flange ɗin.
