Ukubunjwa kweqokobheInkqubo ikwabizwa ngokuba yinkqubo yokugalela yentlabathi eqatywe ngaphambili, ukubunjwa kweqokobhe elishushu okanye inkqubo yokugalela engundoqo. Izinto eziphambili zokubumba yintlabathi ye-phenolic resin efakwe ngaphambili, ebiza kakhulu kunesanti eluhlaza kunye ne-furan resin sand. Ngaphezu koko, le santi ayinakuphinda isetyenziswe.
I-Furan resin self-ukuqina kwesanti inkqubo yokugalela (inkqubo ye-nobake) isebenzisa i-furan resin egqunywe isanti ukwenza i-mold yokuphosa. Emva kokuxuba isanti yoqobo (okanye isanti ebuyisiweyo), intlaka ye-furan elulwelo kunye ne-catalyst engamanzi ngokulinganayo, kwaye uyigcwalise kwibhokisi engundoqo (okanye kwibhokisi yesanti), kwaye emva koko uyiqinise ukuze iqine ibe ngumbumba okanye i-mold kwibhokisi engundoqo (okanye isanti. ibhokisi) kwiqondo lokushisa. Emva koko i-mold casting okanye i-casting core yaqulunqwa, ebizwa ngokuba yi-self-hardening ebandayo-ibhokisi yokubumba (i-core), okanye indlela yokuziqinisa (core).
Ngenxa yokuba umngundo wenziwe kwiqondo lobushushu begumbi kwaye akukho mfuneko yokufudumeza, ukuziqinisa kwesanti kukwabizwa ngokuba yinkqubo yokuphosa yokubhaka. Indlela yokuziqinisa inokwahlulwa ibe yi-acid-catalyzed furan resin kunye ne-phenolic resin sand self-harding method, i-urethane resin sand self-harding method kunye ne-phenolic monoester self-harding method.
Njengesanti ebopha ibhokisi ebandayo ezenza lukhuni, isanti ye-furan resin yeyona ntlabathi yokuqala kwaye ngoku isetyenziswa kakhulu kwisiseko saseTshayina. Isixa se-resin esongeziweyo kwisanti yokubumba ngokuqhelekileyo yi-0.7% ukuya kwi-1.0%, kwaye isixa se-resin eyongezelelweyo kwisanti engundoqo ngokubanzi yi-0.9% ukuya kwi-1.1%. Umxholo we-aldehyde yasimahla kwi-furan resin ungaphantsi kwe-0.3%, kwaye ezinye iifektri ziye zehla ukuya ngaphantsi kwe-0.1%. Kwiziseko zase-China, isanti ye-furan ye-resin yokuziqinisa ifikelele kwinqanaba lamazwe ngamazwe kungakhathaliseki ukuba yinkqubo yokuvelisa kunye nomgangatho womphezulu we-castings.

Izinto eziluncedo zeFuran Resin Coated Sanding Self-harding Molding Casting:
I-1) Ukuphucula ukuchaneka kwe-dimensional of castings kunye noburhabaxa bomphezulu.
I-2) Ukuqina kwe-mold (core) isanti ayifuni ukomisa, enokugcina amandla, kunye neenkuni ezingabizi kakhulu okanye iibhokisi zeplastiki eziphambili kunye neetemplates nazo zingasetyenziswa.
I-3) Isanti yokubumba i-self-hardnening kulula ukuyidibanisa kunye nokudilika, kulula ukuyicoca ii-castings, kunye nesanti esidala sinokuphinda sisetyenziswe kwaye sisetyenziswe kwakhona, esinciphisa kakhulu ubuninzi bomsebenzi wokwenza i-core, imodeli, ukuwa kwesanti, ukucoca kunye nezinye izixhumanisi, kunye kulula ukuqonda umatshini okanye i-automation.
I-4) Ubuninzi beqhekeza le-resin esantini kuphela i-0.8% ~ 2.0%, kwaye ixabiso elibanzi lezinto eziluhlaza liphantsi.
Ngenxa yokuba indlela yokuzenza lukhuni ineenzuzo ezininzi ezichazwe ngasentla, indlela yokuziqinisa ayisetyenziselwanga kuphela ukwenza i-core, kodwa isetyenziselwa ukubumba ukubunjwa. Ilungele ngokukodwa isiqwenga esisodwa kunye nokuveliswa kwebhetshi encinci, kwaye inokuvelisa isinyithi esityhidiweyo, isinyithi esityhidiweyo kunye ne-non-ferrous alloy castings. Amanye amaziko aseTshayina atshintshe ngokupheleleyo abumba isanti eyomileyo yodongwe, imibumbo yesanti yesamente, kunye nenxalenye yokubumba yesanti yeglasi yamanzi.
