What processes are required for manufacturing woven silicone hoses? The first step in the manufacturing process of woven silicone tubing is to extrude the inner tube. Usually, when extruding the inner tube, we request the customer to try to achieve a wall thickness between 1-2mm. If the inner tube wall thickness is too thin, it will cause a lack of support, and the soft fibers will easily fall off during weaving, resulting in unsuccessful weaving. We can also customize inner tubes, which can be made of high temperature resistant, colored, flame-retardant, etc., for use in special fields. For example, the inner tube is black and the outer tube is transparent, and the inner tube is made of high temperature resistant adhesive while the outer tube is made of ordinary high transparency adhesive. The consumer process of weaving silicone tubing inner tubes can meet various industry applications.

After extruding the inner tube, it is necessary to weave fiber thread. Conventional woven silicone hoses can withstand pressures of 12-38 kilograms or more, but some customized customers do not require compression resistance. They usually require resistance to negative pressure or ultra-high pressure, and fiber thread cannot meet customer requirements. We usually use high-strength woven fabrics such as nylon fishing lines. After changing the woven fabric, the product can withstand pressure or negative pressure to enhance its strength. It should be noted that steel wire silicone hoses cannot be stopped from weaving. The inner tube is pulled by a weaving machine through a weaving net composed of several weaving machine heads. At this time, the weaving net will wrap around the inner tube (the weaving machine head will be programmed to weave according to a fixed road, so the silicone threads seen will stop weaving regularly instead of randomly). All conventional woven silicone tubes must be stopped with the weaving machine, so this step is the most important step in all processes. And the selected woven fabric needs to be resistant to high temperatures. As the silicone vulcanization process stops at high temperatures, it is also necessary to install the weaving machine head properly. Since there are many heads, not just one, any problem with any one of them can lead to the occurrence of product weaving disorder.

The final step in the manufacturing of the inner tube and braided wire is to stop extruding the outer tube. This process may seem simple, but it is also very difficult to practice. It is important to note that when the inner tube is wrapped with fiber thread and passes through the extruder, there will be an internal space that carries a small amount of air. At this time, if the silicone outer tube is extruded, bubbles will appear, causing unevenness in the outer tube.

Solution: It is possible to make the outer wall thickness slightly thicker. When extruding the silicone outer tube, the material weight of the outer tube will shrink more tightly, forcing the internal air to the outside can alleviate such problems. Another reason is that increasing the wall thickness of the outer tube will stop burying the originally uneven outer wall, which can deal with the uneven appearance of the braided silicone tube. Extrusion of the outer tube is also the last step in all manufacturing processes of braided silicone tubes and marks the end.
