The first mating section is machined as a slope with a cutting depth gradually increasing from the side near the outer wall to the side near the inner wall, and a blind hole is correspondingly machined. An insert with a coefficient of linear expansion greater than that of the insulation material is inserted into the blind hole for mating.

Driven by this force, the insulation material around the hole wall is forced to undergo local extrusion deformation, protruding into the gap to actively absorb high-temperature thermal stress, mitigate the risk of cracking, and force the gap to close, establishing a tight thermal barrier.
