He lālā ʻo Dongguan Enuo mold Co., Ltd o Hong Kong BHD Group, ʻo ka ʻoihana nui ka hana ʻana i ka ʻōpala injection a me ka hoʻoheheʻe ʻana i ka injection. Eia kekahi, he hale hana OEM nō hoʻi ʻo Enuo mold e hana ana i ka R&D o nā mea nānā/Gauge, Die casting, CNC machining, Prototype products R&D, Parts spraying a me ka ʻākoakoa ʻana.
ʻO ka hoʻolei make he hana hoʻolei metala i hōʻailona ʻia e ke kaomi ʻana i ka metala i hoʻoheheʻe ʻia ma lalo o ke kaomi kiʻekiʻe i loko o kahi lua mold. Hana ʻia ka lua mold me ka hoʻohana ʻana i ʻelua mau make kila paʻakikī i hana ʻia i loko o ke ʻano a hana like me kahi mold injection i ka wā o ke kaʻina hana. Hana ʻia ka hapa nui o nā hoʻolei make mai nā metala non-ferrous, ʻo ia hoʻi ka zinc, ke keleawe, ka alumini, ka magnesium, ke kēpau, ka pewter, a me nā mea hoʻohuihui tin. Ma muli o ke ʻano o ka metala e hoʻolei ʻia ana, hoʻohana ʻia kahi mīkini lumi wela a anu paha.
ʻO nā lako hana hoʻolei a me nā make metala e hōʻike ana i nā kumukūʻai kapikala nui a ʻo kēia ke kumu e kaupalena ai i ke kaʻina hana i ka hana nui. ʻO ka hana ʻana i nā ʻāpana me ka hoʻohana ʻana i ka make casting he mea maʻalahi ia, e pili ana i ʻehā mau ʻanuʻu nui, e mālama ana i ke kumukūʻai hoʻonui no kēlā me kēia mea.
Ua ʻae nui ʻia ua neʻe aku nā kamaʻāina mua o ʻAmelika ʻĀkau mai Siberia ma ke alahaka ʻāina ʻo Bering a hōʻea i ka liʻiliʻi he 12,000 mau makahiki i hala; akā naʻe, ke hōʻike nei nā hōʻike e piʻi aʻe ana i kahi hōʻea mua. Ma hope o ke hele ʻana ma ke alahaka ʻāina, ua neʻe aku nā ʻAmelika mua i ka hema ma ke kahakai Pākīpika a ma o kahi alaloa hau ʻole ma waena o nā papa hau Cordilleran a me Laurentide. Ua puka mai ka moʻomeheu Clovis ma kahi o 11,000 BC, a ua manaʻo ʻia ʻo ia ke kupuna o ka hapa nui o nā moʻomeheu ʻōiwi hope o ʻAmelika.
