The appearance and shape of the silicone hose of the sealing machine are different but similar, but the actual effect is the same, nothing more than the requirements of shock absorption, heat resistance, and aging resistance. The reason why the structure design of the silicone hose of the sealing machine is mostly in the middle Hollow out, this is because firstly the middle part is hollowed out to effectively reduce the cost of the silicone hose of the sealing machine, because the price of silicone is quoted according to the weight. To put it bluntly, if the middle part is not hollowed out, the cost will increase for no reason. No one is willing to accept it. Yes, the second is that the middle hollow can increase the cushioning process. The gas can be discharged through the hollow, so that the characteristics and rebound effect can be effectively increased. If it is solid, the rebound in the silicone hose of the sealing machine often does not have this kind of central hollow. The silicone hose of the sealing machine has good elasticity. In this case of choice, there is no doubt that this hollowing out treatment method will be chosen. In addition, the compatibility of silicone is also good. As long as the design is reasonable, the silicone hose of the sealing machine is almost universal. It can be produced, which must conform to the science of silicone extrusion and actual production conditions.
