Extrude and mold are 2 common methods for silicone hose. While both of them produce high performance silicone hoses. But there are some differences in terms of production process, cost and usage. Next, let me show you the 2 methods.
Extruded Silicone Hose
Extruded silicone hose is to force the silicone through a die, which gives them a consistent diameter and wall thickness. The process is continuous, while it means that the process can be quickly and efficiently. Extruded hoses are typically for simple and straight-line uses such as coolant hose or vacuum hose.
Extruded silicone hose costs not that much to produce than molded silicone hose. Thus it’s an attractive option for cost sensitive apps.
Extruded silicone hoses works as well as the new one after few years. Thus it can ensure the flow rate and prevents leaks.
Molded Silicone Hose
Molded silicone hose is made by injecting liquid silicone into a mold. Then cures to produce the final shape of the hose. The process is more complex than extrusion. Thus molded hose is more expensive than extruded hose. It is ideal for complex and curved apps such as turbo hose or intake hose.
More Complex Shape
Molded silicone hose can be in more complex shape. Thus it’s ideal for DIY usage. For example, the race car and refitted car.
Molded silicone hose has a higher burst pressure than extruded hose. So it’s more suitable for high pressure app.
Greater Temperature Range
Molded silicone hoses can work at a wider temp range. So it’s ideal for the apps where is high or low in temp.
Whether it is Extruded Silicone Hose or Molded Silicone Hose. Our company can produce high performance silicone hoses.
