Izinto ezisetyenziswa ekwenziweniiidayi zokunyathelaziquka intsimbi, i-carbide eqinisiweyo ngentsimbi, i-carbide, ii-alloys ezisekelwe kwi-zinc, izinto ze-polymer, i-aluminium bronze, ii-alloys eziphezulu nezisezantsi zokunyibilika njalo njalo. Uninzi lwezixhobo ezisetyenziswa ekwenzeni ii-dies zokunyathela ikakhulu ziintsimbi. Iindidi eziqhelekileyo zezinto ezisetyenziselwa iindawo zokusebenza zee-dies zezi: intsimbi yesixhobo sekhabhoni, intsimbi yesixhobo se-alloy ephantsi, intsimbi yesixhobo se-chromium ephezulu okanye ephakathi, intsimbi ye-alloy yekhabhoni ephakathi, intsimbi yesantya esiphezulu, intsimbi ye-matrix kunye ne-carbide, i-carbide eqinisiweyo ngentsimbi, njl.

1. Intsimbi yesixhobo esingenamthungo ophantsi

Intsimbi yesixhobo esine-alloy ephantsi isekelwe kwintsimbi yesixhobo sekhabhoni ngokongezwa kwenani elifanelekileyo lezinto ezidibanisayo. Xa kuthelekiswa nentsimbi yesixhobo sekhabhoni, kunciphisa ukuqhekeka nokuguquka kokuguquguquka, kuphucula ukuqina kwentsimbi, ukumelana nokuguguleka nako kungcono. Intsimbi ene-alloy ephantsi esetyenziswa ekwenzeni ii-molds yi-CrWMn, 9Mn2V, 7CrSiMnMoV (ikhowudi CH-1), 6CrNiSiMnMoV (ikhowudi GD) njalo njalo.

2. Isixhobo sekhabhoni sentsimbi

Ukusetyenziswa okungakumbi kwi-mold ye-carbon tool steel ye-T8A, T10A, njl., iingenelo zokusebenza kakuhle kokucubungula, zingabizi. Kodwa ukuqina kunye nobunzima obubomvu abulunganga, ukuguqulwa konyango lobushushu, amandla aphantsi okuthwala umthwalo.

3. Intsimbi ekhawulezayo

Intsimbi ekhawulezayo inobunzima obuphezulu, ukumelana nokuguguleka kunye namandla okucinezela entsimbi yokubumba, amandla aphezulu okuthwala umthwalo. Ezisetyenziswa kakhulu kwiinkuni yi-W18Cr4V (ikhowudi 8-4-1) kunye ne-tungsten encinci ye-W6Mo5Cr4V2 (ikhowudi 6-5-4-2, uphawu lwe-United States M2) kunye nokuphucula ukuqina kophuhliso lwentsimbi ye-vanadium enekhabhoni encitshisiweyo ye-6W6Mo5Cr4V (ikhowudi 6W6 okanye i-M2 enekhabhoni ephantsi). Iintsimbi ezikhawulezayo nazo zifuna ukuphinda zifakwe ukuze kuphuculwe ukusasazwa kwazo kwekhabhoyidi.

4. Iintsimbi zezixhobo ze-chromium eziphakathi ezinekhabhoni ephezulu

Iintsimbi zezixhobo ze-chromium eziphakathi ezinekhabhoni ephezulu ezisetyenziselwa ukubumba yi-Cr4W2MoV, i-Cr6WV, i-Cr5MoV, njl., umxholo wazo we-chromium uphantsi, i-carbide encinci ye-eutectic, ukusasazwa kwe-carbide, ukuguqulwa konyango lobushushu kuncinci, kunye nokuqina okuhle kunye nozinzo olulinganayo. Xa kuthelekiswa nokwahlulwa kwe-carbide, intsimbi ye-chromium ephezulu enekhabhoni ephezulu iphucukile.

5. Intsimbi yesixhobo esinekhabhoni ephezulu ene-chromium ephezulu

Isixhobo sentsimbi esine-carbon ephezulu esisetyenziswa rhoqo yi-Cr12 kunye ne-Cr12MoV, i-Cr12Mo1V1 (ikhowudi D2), sinokuqina okuhle, ukuqina kunyeukumelana nokuguguleka, ukuguqulwa konyango lobushushu kuncinci kakhulu, kwisinyithi sokubumba esinokumelana nokuguguleka okuphezulu, umthamo wokuthwala ulandela owentsimbi ekhawulezayo. Kodwa ukwahlulwahlulwa kwe-carbide kukhulu, kufuneka kuphazamiseke ngokuphindaphindiweyo (ukuphazamisa i-axial, umzobo we-radial) ukutshintsha i-forging, ukuze kuncitshiswe ukungalingani kwe-carbide, kuphuculwe ukusetyenziswa kwayo.

6. I-carbide eqinisiweyo kunye ne-carbide eqinisiweyo yentsimbi

Ubunzima kunye nokumelana nokuguguleka kwe-carbide eqinisiweyo kuphezulu kunokwalo naluphi na olunye uhlobo lwentsimbi yokubumba, kodwa amandla okugoba kunye nokuqina akukuhle. I-carbide eqinisiweyo esetyenziselwa ukubumba yi-tungsten kunye ne-cobalt, kwaye kwiibumba ezinempembelelo encinci kunye neemfuno zokuguguleka okuphezulu, i-carbide eqinisiweyo ephantsi komxholo we-cobalt ingasetyenziswa. Kwiibumba ezinempembelelo ephezulu, i-carbide enomxholo we-cobalt ophezulu ingasetyenziswa.
