Rubber extrusions are continuous lengths of rubber shaped into various cross-sections through an extrusion process. This versatile manufacturing method allows for the creation of a wide range of rubber products with precise dimensions and consistent quality.
The Extrusion Process:
- Compounding: Raw rubber is mixed with additives like fillers, pigments, and vulcanizing agents to achieve desired properties.
- Extrusion: The compounded rubber is fed into an extruder, where it is heated, melted, and forced through a shaped die, creating a continuous profile.
- Curing: The extruded rubber is then cured (vulcanized) to harden and stabilize its properties.
Common Shapes and Applications:
- O-rings: Circular cross-sections used for sealing applications.
- Gaskets: Various shapes and sizes for sealing joints and flanges.
- Seals: Customized profiles for sealing doors, windows, and other openings.
- Hoses: Tubular shapes for conveying fluids and gases.
- Weatherstripping: Used to seal gaps around doors and windows to prevent air and water infiltration.
- Automotive parts: Bumpers, seals, and other components.
- Industrial components: Vibration mounts, conveyor belts, and more.
Advantages of Rubber Extrusions:
- Versatility: Wide range of shapes and sizes can be produced.
- Cost-effectiveness: Efficient production process for large quantities.
- Consistency: Uniform properties and dimensions throughout the length.
- Customization: Rubber compounds can be tailored to specific requirements.
