I-Dongguan Enuo mold Co., Ltd iyinkampani engaphansi kwe-Hong Kong BHD Group, ibhizinisi eliyinhloko ukukhiqizwa kwesikhunta somjovo kanye nokubumba umjovo. Ngaphezu kwalokho, isikhunta se-Enuo siyifektri ye-OEM ebandakanyeka ekuhlolweni kwemishini/ukuhlolwa kwe-Gauge, ukuphonswa kwe-die, ukushintshwa kwe-CNC, ukuhlaziywa kwemikhiqizo ye-Prototype kanye nokuthuthukiswa, ukufuthwa kwezingxenye kanye nokuhlanganiswa.
Isikhunta sakhiwe yizingxenye ezimbili eziyinhloko, isikhunta somjovo (ipuleti A) kanye nesikhunta se-ejector (ipuleti B). Lezi zingxenye zibizwa nangokuthi i-moulder kanye ne-moulder maker. I-resin yepulasitiki ingena esikhunta nge-sprue noma isango esikhunta somjovo; i-sprue bushing iwukuvala ngokuqinile embhobho wombhobho womjovo womshini wokubumba nokuvumela ipulasitiki encibilikisiwe ukuthi igeleze isuka emgqonyeni iye esikhunta, eyaziwa nangokuthi i-cavity. I-sprue bushing iqondisa ipulasitiki encibilikisiwe esikhunta ngeziteshi ezifakwe ebusweni bamapuleti A kanye no-B. Lezi ziteshi zivumela ipulasitiki ukuthi ihambe ngazo, ngakho-ke zibizwa ngokuthi ama-runner. Ipulasitiki encibilikisiwe igeleza esikhunta bese ingena esangweni elilodwa noma ngaphezulu elikhethekile futhi iye ku-geometry yesikhala ukuze yakhe ingxenye oyifunayo.
Nakuba ukulinganisa inani labantu bokuqala bomdabu baseNyakatho Melika ngesikhathi sokuxhumana kwaseYurophu kunzima, umzamo wenziwa engxenyeni yokuqala yekhulu lama-20 nguJames Mooney esebenzisa amarekhodi omlando ukulinganisa inani labantu bomdabu enyakatho yeMexico ngo-1600. Eminyakeni yamuva nje, uDouglas H. Ubelaker weSmithsonian Institution ubuyekeze lezi zibalo. Ngenkathi u-Ubelaker elinganisela ukuthi kwakukhona inani labantu abangu-92,916 emazweni aseningizimu ye-Atlantic kanye nenani labantu abangu-473,616 emazweni aseGulf, iningi lezazi libheka leli nani njengeliphansi kakhulu.
