为了了解硬质合金模具的复杂性,必须弄清原材料钨和钴的来龙去脉及直到成品为止的必要工艺过程。各大陆都有钨矿石开采。中国钨矿石的储藏量为世界之首。其他主要的储藏国为澳大利亚、奥地利、玻利维亚、巴西、加拿大、南北朝鲜、葡萄牙、泰国、美国和苏联。目前美国开采中的主要矿山是California州Bishop联合碳化物公司拥有的Pinc Creek矿,Coloado州Leadville AMAX公司拥有的Climax矿,Nevada Tempiut联合碳化物公 In order to understand the complexity of the carbide mold, must understand the origin of tungsten and cobalt and the ins and outs until the finished product necessary process. All continents have tungsten ore mining. China’s tungsten ore reserves in the world. Other major storage countries are Australia, Austria, Bolivia, Brazil, Canada, North and South Korea, Portugal, Thailand, the United States and the Soviet Union. The major mines currently being mined in the United States are the Pinc Creek mine owned by Bishop Union Carbide Corporation of California, the Climax mine owned by Leadville AMAX Corporation of Coloado, the Nevada Tempiut Union Carbide
