Aiming at the honeycomb sandwich structure in satellite, the new post-insert and its automatic post-insert technology are studied. Compared with the traditional post-insert technology in satellite field in China, the influence of two different insert technologies on the bearing capacity and bearing coefficient of inserts is investigated. The results show that the load-bearing modes of the two inserts are basically the same, and the distribution form of adhensive has an important influence on the load-bearing performance. At present, the bearing capacity of the new post-insert system has reached 158.2% of the post-insert system. The new post-insert technology is more suitable for automation mode to ensure process stability, consistency and reliablity.
