Extrusion molding

What is Extrusion molding?

Various industries use rubber products manufactured with extrusion molding method. Extruded rubber items significantly differ from other items manufactured with molding technologies. Extruded products are forced through a die forming a pipe-shaped product which’ size can be adjusted. The final shape of the extruded rubber profile depends on the shape of the die. Unlike the injection molding method, extrusion-molding process results long, continuous shapes which are commonly applied by a range of industries.

Expertise

There are two ways how rubber manufacturers like SIC produce extruded rubber. Horizontal rubber extrusion allows the making of extra-long rubber profiles while vertical rubber extrusion machines provide long rubber profiles with perfectly precise shape and sizes. Extruded rubber parts are also linkable, creating precise joints. Our vertical and horizontal extrusion machines are capable of continuous, automatized production – serving different industries demanding long rubber parts.

Technological advantages

Applications

Long, extruded rubber products are highly sought-after by glass industry, automotive and motorsport industry. From L-sections used in doors and windows to seals and pipes used in cars or motors we produce a wide range of extruded rubber parts that meets businesses’ requirements.

Challenge

Rubber – metal part seems perfect on room temperature after production, but during operating conditions it contacts oil and the angular seals are loosing the sharp edges, so the seal is imperfect.

Solution

With the method of reverse engineering we have developed a compound, which reaches its final form when it is in contact with oil, so the perfect seal is granted during operation.
