Tungsten alloy pin gauge for testing is mainly used to measure the hole size, hole distance, hole depth. It can be used as check gauge, hole standardization monitoring tools. Its performance is stable, so the use of the process can achieve the characteristics of deformation resistance to maintain accuracy. It is widely used in electronic boards, circuit boards, molds, precision machinery manufacturing and other high-tech fields. Chinatungsten Online has more than 20 years of tungsten alloy production experience, which has…
