Why Silicon is Preferred by Rubber Extruder Manufacturers

Silicone rubber extrusion is a continuous process utilized by Rubber Extruder Manufacturers  in which a catalyzed compound (usually continuous strips) is introduced into a feed system via a screw that transports the material to a nozzle. Pressure and temperature increase near the die to achieve the required viscosity. The screw is a key mechanism in the extruded rubber process as it feeds and pushes the material against the flow so that it enters the die correctly. Again, the screw plays a key role in exiting the rubber silicone die, ensuring the quality and regularity of the profile being produced and preventing unwanted bubbles or unevenness in the final product.

 

This is done by changing the screw geometry, speed, pressure and temperature, and other mechanical parameters. The profile then passes through an oven that hardens the part. There are different types of ovens or furnaces to carry out the healing process, mainly to suit the different catalysts used in the composition. Temperature, pressure, and speed are adjusted according to the extruded rubber material. In simple silicone rubber extrusion, one material is pushed into the nozzle as described above. Co-extrusion is an advanced process which has Impact of Rubber Extruder Manufacturers in which two or more compatible polymer materials are simultaneously extruded in multiple extruders and then fused to produce multi-layer structures such as cables, pipes, panels, sealing mechanisms, etc.

 

The biggest challenge for Rubber Extruder Manufacturers using silicone or co-extrusion technology is to choose the right quality silicone rubber raw materials that are compatible and perform best in their specific mechanical and temperature-controlled processes so that the final products meet specifications and tolerance criteria. and meet legal standards. Silicone rubber can be utilized in various rubber extrusion processes and curing systems to achieve different properties.

What are the advantages of the silicone rubber extrusion process?

In applications, silicone rubber extrusion is one of the most widely used. manufacturing processes, typically for longer parts such as hoses and wires, as well as complex profiles and cross-sections, where multilayer materials are often combined using additional elastomer or reinforcement components. Pressed parts are used to make large and heavy parts for industry, such as oven gaskets, electrical cables, wire insulation, and packages. They are also used in domestic applications such as tubes for food or medical applications such as drains and catheters. Silicone rubber moldings and parts manufactured by silicone rubber extrusion manufacturers  are also particularly valued in applications where dimensional stability and mechanical strength must be maintained under extreme conditions. weather conditions or harsh environment. 

To successfully achieve the desired results with silicone rubber extrusion, several parameters must be considered:

 

Precise and durable nozzles Suitable screw and line speed, voltage, and motor power Correct dimensions, length considerations, and proportions Carefully calibrated extrusion speed, pressure, and temperature control of the material preparation stage to the casting stage, including cooling Furnace temperature, extrusion speed, and casting pressure are key parameters to achieve the right balance between productivity and quality. Among other parameters, the quality of the final parts is achieved by achieving a perfect silicone mesh.

Careful composition  of important materials, including tensile strength, fire resistance, chemical compatibility, compatibility with food or medical products, etc. must be a consideration of custom plastic parts manufacturers. Thermal stability Silicone rubber can withstand extreme temperatures that natural rubber cannot. This factor is very important for areas such as aviation and automation. In addition, heat-resistant rubber is also needed for many other products - household appliances and kitchen utensils. Most compounds can remain completely intact and generally retain their properties at extreme temperatures. Silicone rubber can retain its flexibility even in much colder temperatures, making it an ideal multi-purpose tool for worldwide use.

Excellent hygienic ability

Silicone rubber is non-porous, which makes the accumulation of bacteria practically impossible. As a result, this material is useful for medical products, cookware, and other food applications. Not only that, but silicone rubber is waterproof, non-toxic and recyclable.

 

Extreme versatility

Silicone rubber is the best moldable material. It is easy to mold and can be customized with special properties such as heat and water resistance. Additionally, silicone rubber can be made in any shade imaginable if you need a specific color to match your brand.

 

Very weather resistant

Choosing rapid prototype manufacturer  is a great choice. This weather-resistant material can withstand prolonged exposure to sunlight, UV rays, radiation, extreme temperatures, and storms. Silicone caulking is one of the most popular ways to use silicone outdoors. Because silicone rubber compounds are made from a mixture of silicon and oxygen atoms, it provides a remarkable elasticity that most materials do not have. Silicone rubber is chemically inert and resistant to many substances such as acids and water.

Very flexible

Easily changeable and sensitive silicone rubber offers unparalleled fluidity and flexibility. Prized for its ability to withstand extreme high and low temperatures, this synthetic polymer always maintains its shape and flexibility, no matter what happens.
