Muffler with outer cylinder and the internal honeycomb structure, two parts due to high temperature, vibration and other special environment is by mechanical package buckle process together. We know that the quality of this process depends on the design of the precision, if the combination is not strong in the car will be due to high temperature, vibration and other factors caused by loose or fall off. But let us be assured that the quality of the first sector has been on the technical aspects of the very stringent requirements.

For the actual detection method industry testing tools are using universal testing machine, with a pressure plate fixture, so that the two components of the muffler from the upper and lower shear force. The measured results should be less than 5%.
