以色列阿门金属制品公司在20年前就成功地使用勒斯特150吨压铸机进行了黄铜和铝的压铸。今天其压铸机的吨位提高到了近600吨。黄铜压铸模具的寿命一般为1万模,好的也不过2万次,而该公司的模具寿命可达32万次,其具体做法是,一是在压了20万次后,对模具空腔再进行处理,二是,模具的钢材料好,设计合理。模具钢材为波否氏热性模具钢,其标准组成为:碳-0.3％、铬-2.8％,钼-2.8％,钒-0.5％,钴-2.8％。它同普通模具钢H13的重要区别在于,铬量低,而钼量高,另外又增加了钴。
Israel Amen Metal Products made the brass and aluminum die-casting 20 years ago successfully using the Lest 150-ton machine. Today, the tonnage of its die casting machine has risen to nearly 600 tons. Brass die-casting mold life is generally 10,000 die, but also good, but 20000 times, and the company’s die life up to 320,000 times, the specific approach is, first, after pressing 200,000 times, the mold empty Cavity and then processed, the second is that the mold steel material is good, well-designed. Mold steel is wave-free hot die steel, the standard composition: carbon -0.3%, chromium -2.8%, molybdenum -2.8%, vanadium -0.5%, cobalt -2.8%. It is an important difference with the ordinary mold steel H13 is that the amount of chromium is low, while the high molybdenum, in addition to an increase of cobalt.
