Extrusion and weaving process of woven silicone tubing

Time:2023-03-17Page views:2308

One step in the production process of woven silicone tubing is to extrude the inner tube, which requires the wall thickness to be between 1 and 2 millimeters as much as possible during extrusion. If the inner tube wall thickness is too thin, it can cause the soft fabric to easily fall off when weaving fiber threads without support, leading to weaving failure. For those with special requirements, customized inner tubes can be made into high-temperature resistant, colored, flame-retardant, etc., suitable for special fields. For example, the inner tube is black, the outer tube is transparent, the inner tube is high-temperature resistant adhesive, and the outer tube is ordinary. Both high transparency adhesives are available, indicating that the production process of inner tubes can meet the needs of various industries.

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. They usually need to withstand negative pressure or ultra-high pressure. At this time, fiber thread cannot meet customer requirements and high-strength woven fabrics such as nylon fishing lines are usually used. After replacing the woven fabric, the product's compression or negative pressure resistance ability is strengthened. It should be noted that steel wire silicone hoses cannot be woven. Pull the inner tube through a weaving machine and weave it through a mesh composed of several weaving heads. At this point, the woven mesh will wrap around the inner tube (the weaving head will be programmed to weave according to a fixed route, so the woven silicone threads seen are regular rather than random). Conventional woven silicone tubes require a weaving machine, so this is an important step. Due to the fact that the vulcanization process of silicone rubber is carried out at high temperatures, it is necessary to adjust the machine head properly. Any problem with one of the heads can cause confusion in product weaving.

After the production of the inner tube and braided wire is completed, the extrusion of the outer tube is carried out. This process may seem simple but actually very complicated. It is important to note that the fiber thread wrapped around the inner tube may cause internal space and carry a small amount of air when passing through the extruder. At this time, if the silicone outer tube is extruded, bubbles will appear, causing the outer tube to be uneven. The solution is to make the outer tube wall thickness slightly thicker. When the material of the silicone outer tube is heavy during extrusion, the silicone will shrink more tightly and forcefully extrude the internal air to the outside, which can alleviate such problems. Another reason is that increasing the outer tube wall thickness will bury the originally uneven outer wall, which can solve the problem of surface unevenness. Squeezing the outer tube The production process of woven silicone tubing also marks the completion.
