约在10到15年前,一系列灯丝制造的新工艺问世,,其发展趋势是生产出长的,均匀、无裂痕、易卷绕的灯丝。这无疑对拉丝工艺的改善及金刚石拉丝模的进一步研究起了推动作用。位于匈牙利布达佩斯城的国际灯具制造厂之一的Tungsram公司,为了确保技术的不断发展,在八年前实施了一项计划,即完全实现从工艺流程、机器装置、拉丝模设备及拉丝的 About 10 to 15 years ago, a series of filament-making new processes were introduced. The trend is to produce long, uniform, crack-free, easy-to-wrap filaments. This undoubtedly played a catalytic role in the improvement of the drawing process and the further study of the diamond drawing die. Tungsram, one of the international luminaires manufacturers in Budapest, Hungary, has implemented a plan eight years ago to ensure the continuous development of the technology from process, machine, drawing machine and drawing
