铝压铸件的检测标准介绍

 

 铝压铸件不可避免的存在气孔和夹渣,所以对铝压铸件的检测标准就显的很重要当然不同功用的铸件要求也会有所不同,不知道各大厂商是如何加强对产品的检测我公司检测标准:
  1)铸件的表面不允许有裂纹、欠铸、气泡、擦伤、凹陷、缺肉、网状毛刺等三角型缺陷,同时不允许有拉模现象.
  2)铸件的浇口、飞边、溢流口、隔皮、顶杆痕迹等要清理干净,但允许留有痕迹.铸件分型面的错型量不大于0.3mm,上下两面的平面度不大于0.3mm.
  3)压铸件的顶杆痕迹凹凸量为正负0.2mm.压铸未通孔厚度不大于0.3mm.
  4)加工面不允许有夹杂、冷隔、疏孔等缺陷.对于机加工后可以允许表面气孔直径不大于0.3mm,在3cm×3cm的单位面积上气孔总数不多于3个,孔边距不小于1cm.
