Manufacturing method of drum-type membrane vibration isolator

The invention discloses a manufacturing method of a drum-shaped membrane type vibration isolator. The manufacturing method comprises the steps that firstly, a preformed membrane I and a preformed membrane II are obtained; 2, manufacturing an upper component; thirdly, the first preformed film I and an upper assembly of the drum-shaped film type vibration isolator are connected, and a film connection upper assembly I is obtained; fourthly, the preformed film II and the film connecting upper assembly I are connected, and a film connecting upper assembly II is obtained; step 5, connecting a second pre-formed film I to obtain a film connection upper assembly III; step 6, manufacturing a lower component; seventhly, the lower assembly and the membrane are connected with the upper assembly III, and the drum-type membrane type vibration isolator assembly is obtained; and 8, the phase change material is led out, and the drum-type membrane vibration isolator is obtained. The drum-type membrane vibration isolator obtaine
