优质轻型发动机用的压铸件,由于壁厚变薄,且用铝合金材料和塑料代替了钢而使其易产生渗漏,因此,对它们进行100％的渗漏检测是完全必要的。气体检测技术精确度和灵敏度很高,是一种较实用的渗漏检测方法。
Die-castings for high-quality light-duty engines are susceptible to leakage due to thinner wall thickness and replacement of steel with aluminum alloy and plastic, so 100% leak detection of them is absolutely necessary. Gas detection technology has high accuracy and sensitivity and is a more practical leak detection method.
