Ƙirƙira ita ce hanya mafi sauƙi a cikin samar da kayan aiki mai wuyar gaske, kuma shine maɓalli mai mahimmanci don tabbatar da daidaitattun daidaito da kuma bayyanar da ingancin abubuwan da ba a iya gani ba. Yana da tsari na ƙaddamar da foda a cikin komai tare da siffar da ake so. Abubuwan buƙatun sa shine samun takamaiman ƙarfi da ƙayyadaddun girman.
1. Daidaitaccen gyare-gyare
Matsa madaidaicin ya kamata ba kawai yana da kayan aiki masu kyau ba, har ma da software mai kyau. Musamman, ya zama dole don samun: babban madaidaicin latsa (TPA press), babban madaidaicin mutu, babban cakudewar aiki, ingantattun sigogin tsari da sauran mahimman yanayi.
Matsakaicin matsi ya haɗa da: sake zagayowar latsawa, injin matsi na ma'auni da ma'auni na ƙididdigewa, zaɓin cakuda, zaɓin mutuwa, zaɓin jiragen ruwa, da ingancin latsawa, da dawo da sarrafa kayan aiki, da sauransu.

2. Extrusion forming
Extrusion gyare-gyare yana sanya cakuda a cikin silinda extrusion bayan yin filastik, sa'an nan kuma shigar da mutu a daya gefen silinda extrusion tare da ramukan da ake so a saman wadanda suka mutu. Ana shigar da wani extruder a daya karshen silinda extruder. An wuce matsa lamba na extruder ta hanyar extruder zuwa cakuda, wanda ya ratsa ta cikin rami mai mutu kuma ya zama samfurin siffa.
Amfaninsa shine: tsayin samfurin ba'a iyakance shi gaba ɗaya ba, kuma tsayin tsayin tsayin ya fi daidai. A halin yanzu, yawanci yana da ƙarfin ci gaba da samarwa, ingantaccen aiki tare da kayan aiki mai sauƙi da aiki mai dacewa.
3. Cold isostatic latsawa
Cold isostatic matsa lamba dogara ne a kan ka'idar PASCAL; foda da aka danna an rufe shi a cikin wani nau'i na roba tare da wani nau'i da girman girmansa, sa'an nan kuma sanya shi a cikin rufaffiyar babban matsi. Ana shigar da matsakaicin ruwa a cikin akwati ta hanyar famfo mai matsa lamba, kuma matsakaici yana yin matsin lamba a ko'ina a kan kowane farfajiya na ƙirar roba. Foda a cikin mold kuma yana fuskantar matsi daidai a kowane bangare kuma an rage siffarsa daidai lokacin da aka shigar da shi, ta yadda za a haɗa foda a cikin wani ƙaramin sarari tare da wani nau'i, girma da isasshen ƙarfi.

Sintering shine babban tsari na ƙarshe a cikin samar da siminti carbide. Dalilin sintering shine don canza ƙaramin foda mai ƙyalli a cikin gami tare da wasu tsari da kaddarorin. A sintering na wuya gami ne mafi hadaddun saboda jiki canje-canje da sinadaran halayen, amma yafi saboda jiki tsari, kamar sintering jiki densification, carbide hatsi girma, da canji na bonding lokaci abun da ke ciki da kuma samuwar gami tsarin.
Za'a iya kasu gaba dayan tsarin sintirin zuwa matakai hudu:
Matakin fara ƙonewa (
