Muffler has external cylinder and internal honeycomb components, two parts because of high temperature, vibration and other special environment is the mechanical buckle technology combined. We know that the quality of this process depends on the precision of the design, if the combination of the car in the use of high temperature, vibration and other factors caused loose or fall off. But let us rest assured that the relevant quality of the first sector has put forward a very stringent technical requirements.
For the actual detection methods in the industry, testing tools are using universal material testing machine, with the pressure plate clamp, muffler two components are subjected to upper and lower related shear force. The repeated error of the measured results should be less than 5%.
