Manufacturing Process of Silicone Hoses

Silicone hoses are utilized in a host of applications starting from automotive, food processing, medical, industrial etc. The versatility of silicone rubber makes it suitable to be used in numerous places. Hoses are commonly used in intake systems, air coolers, etc. They’re available in a number of diameters from giant to small and might be ordered in many cuts and bents.

An order of silicone hoses does not take too lengthy to fabricate because the manufacturing process has been personalized by their manufacturers. The manufacturing process requires the correct skills, instruments, materials and the proper time. Here is a detailed look at the manufacturing process of silicone hoses:

Stage 1: Making a Mandrel Software

A mandrel software is a shaping instrument that’s made of metal and is hollow. It’s used to bend silicone rubber in the form and diameter of the desired silicone hose. It is commonly utilized in many other applications like blowing glass.

The first stage is to make mandrel software(s) within the shape of the silicone hose(s). This is done by manipulating steel within the desired form of the hose. These tools are often stored by manufacturers in thousands of shapes and sizes. The scale are available on their website or product catalogue.

Stage 2: Choosing the Raw Materials

The raw materials are chosen specifically for making silicone hoses. These embrace silicone rubber, colour pigments and reinforcement fabrics. Hoses are multi-layered and reinforcement materials are used to offer them strength.

Stage 3: Milling & Calendering

The silicone rubber compound and the colour pigments are combined collectively in a mill. This process is called ‘milling’. It takes round half an hour within the mill to produce a shade pigmented silicone rubber compound.

The colored silicone rubber compound is placed right into a calendaring machine. The machine presses the compound between rollers to make it into thin sheets. The calendaring machine then presses the flattened compound on to the reinforcement fabric. Now the fabric is ready at hand build the hoses.

Stage four: Cutting & Rolling

The thin sheets are reduce and piled to roll. The builders roll the thin sheets in tubes. It is needed to take care of the correct thickness of the tubes. A completed tube must have the correct number of reinforcement plies. Now these tubes are ready to be used for building hoses.

The silicone tubes are carefully pushed on the mandrel instruments to provide the desired shape. Any air bubbles or joints are smoothed out. Silicone hoses that have additional joints or bends want extra care to push the tubes into shape.

Stage 5: Oven Curing, Cooling & Stripping

The silicone hoses are then cured within the oven and then cooled down. This offers them the desired shape. To remove them, they’re stripped from the mold in one swift motion and put in the wash hose for cleaning. The hoses are then sent for trimming and inspection.

Stage 6: Trimming & Inspection

Earlier than trimming the hose is marked the place the sting has to be cut. The sides are then minimize using a machine for fine edges. After trimming the silicone hoses are sent for quality inspection. As soon as they’re approved they are ready for shipping to the client.
