    摘要: A substrate assembly is stuffed into a converter outer shell to form a catalytic converter having a desired gap bolt density (GBD) value. The substrate assembly is formed by wrapping and taping a mat around a catalytic substrate. A predetermined pressure is applied to the substrate assembly and an outer diameter of the substrate assembly is measured at this predetermined pressure. A GBD value is predicted based on this measurement and if the GBD value is acceptable the substrate assembly is stuffed into the converter outer shell.
