Everything you need to know about the Rubber Extrusion process.
Rubber extrusion is the process of turning rubber materials into a specifically shaped product. To provide this shape, manufacturers use a rubber extruder machine.
The rubber extruder has two main parts: a heated shearing screw conveyor and a die.
Rubber extruded products are commonly applied for industrial applications that require sealing. Some examples are:
Also known as extruded top and side seals, these profiles are designed to fill the gaps between doors and door frames to prevent wind and water from entering a vehicle or building.
They are used in cars and trucks, as well as in many commercial and industrial facilities. Door seals such as hatch seals can also be found in fuel tanks, rooftop HVAC systems and in electronic enclosures.
Edge trim profiles are used to cover rough edges made from plastics and steels. These types of rubber extruded profiles are made from flexible materials and have gripping tongues that allow them to provide a much stronger hold. Edge trim profiles are usually found in automotive and marine industries, and are used for applications such as decorative trims for boats, cars and buildings.
Rubber bumpers and fenders protect the hull and berthing infrastructure from damage when vessels berth alongside. The fender functions as a shock absorber by absorbing the energy of a vessel on the berthing facility. There are many service factors which must be taken into consideration when making a decision on which type and size of fender is best suited for a given application. D-shaped bumpers are also used on the rear of trucks and trailers to protect the vehicle from damage when reversing into loading docks.
Whether by extrusion or any other rubber processing methods, there is no denying that rubber is an excellent material for many everyday applications.
At Derby Rubber, we work with our clients to precisely determine the product that will best meet their needs.
In addition to the general-purpose rubbers, [e.g. Natural Rubber, EPDM, SBR, NBR, CR (Neoprene™) etc.], Derby Rubber is also able to extrude specialty rubbers such as fluoro elastomers [e.g. Viton™, Dyneon™ etc.] with a high degree of accuracy.
Our team will help you define the exact operating environment the product will be used in, including the temperature range, and the material and radiant exposures. Rest assured that we don’t just rely on our past achievements for continued success. Rather, we constantly look for challenges and opportunities provided by you to help us continually grow and improve our processes and techniques.
