Coffee machines are popular around the world to bring people rich, refreshing and refreshing drinks, which can greatly save the time of making coffee. This fully automatic process is carried out under high temperature and high pressure, and silica gel as a high temperature resistant material can not only It can also resist pressure when it meets food grade requirements. At present, the general pressure resistance requirements of coffee machines are 30-40KG, and food grade silicone braided tubing have stronger pressure resistance than ordinary Silicone tubing. It can circulate the pressure in the three links of silica gel, braid, and outer silica gel to make each surface bear the pressure evenly, but there is also an upper limit. The burst pressure of the silicone braided tubing of the coffee machine cannot exceed 45 kg. In addition, the upper limit of burst pressure can be increased a little bit by adding vulcanization twice.

 

The size of the silicone braided tube will directly affect the pressure. For example, the smaller the size of the silicone braided tube for coffee machines, the higher the compressive performance. The mainstream sizes are 3*8, 4*8, 4*9, and 5*11. The wall thicknesses are 2.5mm, 2mm, 2.5mm, 3mm, and the compressive capacity of thicker walls will naturally be higher than that of thinner walls. After all, the pressure-bearing volume will increase more stably. Secondly, it is because of the circulation of coffee. The tube diameter should not be too large to meet the daily use specifications, but the more it is, the higher its pressure resistance. In summary, the factors that can affect the burst pressure of the silicone braided tube of the coffee machine are: braid, product size, secondary vulcanization, and wall thickness. These four aspects can reach ≥38 if there is no problem. The pressure above kilograms is very high in most of the silicone braided tubing.
