Rubber Extrusion
The quality of the rubber sealing strip made by the rubber extrusion process is better. okin is a professional rubber strip manufacturer. Rubber extrusion seal strips have a wide range of applications. Changing the extrusion to ensure that extruded rubber seals with various cross-sectional shapes. And most importantly, there is no length limit for the rubber extrusion seal. Today, rubber extrusion is very popular in the market.
Rubber Co-Extrusion
The extruded rubber seal strip is durable and easy to install. Because the rubber co-extruded profile is mainly composed of EPDM rubber foam, it is dense and contains unique metal clamps and tongue-shaped buckles. okin is an excellent rubber extrusion supplier. When looking for extruded rubber seal service, you must find a professional.
Sponge Extrusion
The raw material of the sponge extruded sealing strip is EPDM rubber, which is a synthetic rubber. The primary ingredient is ethylene. Its main feature is that it has a low density and high filling and is resistant to aging, corrosion, water vapor, and superheated water. Nowadays, sponge seals have advantages that cannot be ignored. It has good toughness and softness. It is very light and will not add any weight to the transportation of sponge seals.
Plastic Extrusion
A plastic seal strip is a straightforward product that is used daily. For example, some door and window sealing strips, decorative sealing strips on cabinets, etc., are all PVC strips. During production, a plastic extruder produces the plastic sealing strip. The plastic sealing strip is resistant to corrosion, aging, and high and low temperatures. This environmentally friendly product has good anti-seepage, anti-leakage, and water-proof effects. okin rubber strips supplier provides you with great products.

Wide Applications of Rubber Sealing Strip
Window Seal & Door Seal Strip
A sealing strip is necessary for sound insulation, wind protection, or dust and insect protection. Whether it is door seal strips or window sealing, they are made of durable rubber or PVC. It can help our customers solve problems quickly.
Car Window Seal & Car Door Seal

Seal Strip For Rail Vehicle
A marine weather strip with good aging resistance is critical. Seals are rarely replaced frequently. Good oxidation resistance helps to improve the service life of the sealing strip. Even after long-term use, it can ensure a good use effect.
Rubber Extrusion Manufacturing Process
- Material Preparation: Choose the appropriate rubber material. It is usually a polymer with good elasticity and abrasion resistance, such as styrene-butadiene rubber (NBR), ethylene-propylene rubber (EPDM), etc.
- Extruder Settings: Adjust parameters such as the extruder’s temperature, pressure, and speed. This ensures that the material receives proper heat and pressure during extrusion.
- Pressing and Preheating: The rubber material is placed in the hopper of the extruder. Feed through the screw while heating and melting the material in the preheating zone.
- Die Design And Installation: Design and manufacture the appropriate extrusion die according to the required sealing strip size and shape. Install the die on the extruder, ensuring it is properly adjusted and centered.
- Extrusion Process: Push the preheated rubber material from the outlet of the extruder into the mold and apply proper pressure. The rubber is passed through a mold to form the desired weatherstrip shape. During extrusion, the rubber passes through a cooling zone to solidify.
- Cutting And Handling: The extruded weatherstrip is cut to the appropriate length. Subsequent processing steps, such as edge deburring, surface treatment, or processing unique shapes, may be required as needed.
- Inspection And Quality Control: Extruded weatherstrips are inspected to ensure they meet size, appearance, and performance specifications. The necessary quality control measures are carried out to ensure stable product quality.
- Packaging And Shipping: Extrude the finished rubber into sealing strips for packaging. Label and sort according to customer needs, ready to ship to customers.
