Semugadziri wekugadzira mold muChina, Kuenzanisa neyemukati mold, kutengesa mold mitengo yakakwira zvakanyanya mumakore apfuura, gap rinokonzerwa nediffriend standard. IAmerican Society of Plastic Industry (SPIAN-102-78) inoparadzanisa mold muzvikamu zvishanu. Aya marudzi mashanu emamold ane zvakasiyana zvinodiwa, uye chiyero chechikamu chinongoshanda chete kuenzanisa muchina wejekiseni uyo unosunga simba usingasviki mazana mana ematani.
Hupenyu kutenderera nguva kusvika miriyoni imwe nguva, yakakosha kune yakakwira kugadzirwa kwechigadzirwa. Kusarudza yakanakisa mold simbi yekugadzira, inoenderana iyi giredhi mold inoda mutengo wepamusoro. Zvinodiwa zvinoratidzwa sezvinotevera:
(1) Inoda kuve neruzivo rwakadzama rwekugadzira mold.
(2) Mold base kuoma zvinodiwa kanenge BHN280 (HRC30).
(3) Mold surface (kusanganisira mhango uye core molds) zvirinani muBHN450 (48HRC) kuomarara renji, zvimwe zvese zvishongedzo zvakaita sema slider, lifters, straight lifters, etc. zvinofanirwa kuoma.
(4) Iyo ejection system ichave neinotungamira system.
(5) Musevedzeri wepadivi unofanirwa kuiswa nendiro yekupfeka.
(6) Cavity mold, core mold, slider uye zvimwe zvikamu mu mold zvinofanira kuiswa pamwe nekushisa-kunzwa.
(7) Nezve hupenyu hwehuvhu, mhando yechigadzirwa ichadzikiswa kana kuumba kutenderera-nguva yakawedzerwa nekuda kwekutonhora kwepombi yemvura yakasvibiswa zuva nezuva, saka iyo yekuisa kana mold ndiro yakarairwa kuita anti-corrosion kurapwa.

GRADE 2
Hupenyu kutenderera nguva kusvika 500,000 kusvika 1, 000,000 nguva. Kugadzira zvigadzirwa zvakakura, simbi yemhando yepamusoro ichashandiswa kugadzira, mutengo unodhura. Zvinodiwa ndezvizvi:
(1) inoda kuve neruzivo rwakadzama rwekugadzira mold.
(2) Mold base kuoma zvinodiwa kanenge BHN280 (HRC30).
(3) Cavity uye core surface hardness ichave muhuwandu hweBHN540 (HRC 48), zvimwe zvese zvinoshanda zvinofanirwa kupiswa.
(4) Isa tembiricha-inonzwa pane mhango mold, core mold, masiraidhi uye imwe nzvimbo inogoneka.
(5) Zviumbwa zvese zverudzi urwu zvichange zvakashongedzerwa ne mold clamping mechanism pakati penzvimbo yekuparadzanisa mutsara.
(6) Izvo zviri pazasi zvinhu zvinokwanisika zvinodikanwa kana kwete, zvichienderana nehuwandu hwekupedzisira hwekugadzira. Zvinokurudzirwa kuti zvinhu izvi zvakare zviite quotation yakasimbiswa.
Ejector inotungamira sisitimu, Slider kupfeka ndiro, anti-kuvhuvhuta Colling manifold, Electroplating pamhango mold (anti-corrosion).
GRADE 3
Kutenderera nguva kusvika ku500,000 nguva. Inoshandiswa seyepakati yehuwandu hwekugadzirwa kwezvinhu, mutengo unonzwisisika. Zvinodiwa ndezvizvi:
(1) inoda kuve neruzivo rwakadzama rwekugadzira mold.
(2) Mold base kuoma zvinodiwa zvishoma neBHN165 (HRC17).
(3) mhango uye core molds zvinofanirwa kunge zvine BHN280 (HRC30) kuoma kana kupfuura.
(4) zvimwe zvese zvinongedzo zvakasununguka kusarudza nevatengesi.
GRADE 4
Hupenyu kutenderera nguva kusvika ku100,000 nguva. Kune yakaderera kugadzirwa kwezvigadzirwa, mold material kupfeka kuramba haina kukwirira, mutengo wakaderera pane yakajairika level. Zvinodiwa ndezvizvi:
(1) Ratidza kupa ruzivo rwekugadzira mold.
(2) Iyo mold base inogona kunge iri simbi yakapfava kana simbi yealuminium.
(3) Iyo mhango mold inogona kunge iri simbi yealuminium, simbi yakapfava kana zvimwe zvinhu zvinogona kuzivikanwa.
(4) Zvese zvishongedzo zvakasununguka kusarudza nevatengesi.
GRADE 5
Kutenderera nguva hakuna kupfuura 500 nguva. Inoshandiswa kugadzira nhamba shoma yemuenzaniso wekutanga, mutengo wakachipa zvakanyanya. Zvinodiwa ndezvizvi:
Iyo mold chimiro inogona kunge iri die-cast material, epoxy resin, kana zvimwe zvinhu zvinopa simba rakakwana kuburitsa yakaderera nhamba yezvikamu.
