Rubber Mouldings and Fabrications

Rubber moldings and fabrications refer to custom-made rubber components that are manufactured through molding and fabrication processes. These rubber parts are used in various industries for a wide range of applications, including sealing, cushioning, vibration isolation, and impact protection. Here are some key features and considerations of rubber moldings and fabrications:

  1. Materials: Rubber moldings and fabrications are typically made from synthetic rubber compounds such as EPDM, neoprene, silicone, Nitrile (NBR), or natural rubber. Each material offers unique properties such as flexibility, durability, resistance to temperature, chemicals, and UV radiation, making it suitable for specific applications.

  2. Manufacturing Processes:

    • Compression Molding: Compression molding is a common method used to manufacture rubber moldings. It involves placing rubber compound material into a heated mold cavity and compressing it under pressure until it takes the shape of the mold.
    • Injection Molding: Injection molding is another method used to produce rubber parts, especially for complex shapes and high-volume production. It involves injecting molten rubber material into a mold cavity under high pressure, where it cools and solidifies into the desired shape.
    • Extrusion: Extrusion is used to create continuous lengths of rubber profiles, such as seals, gaskets, and tubing. The rubber compound is forced through a die of the desired shape, where it is cured and cut to the required length.
    • Fabrication: Fabrication processes such as cutting, bonding, and machining may be used to further process rubber moldings and create custom shapes, sizes, and configurations to meet specific requirements.
  3. Customization: Rubber moldings and fabrications can be customized to meet the precise specifications and requirements of each application. This includes custom shapes, sizes, tolerances, hardness levels (durometer), colors, and surface finishes.

  4. Applications: Rubber moldings and fabrications are used in a wide range of industries and applications, including automotive, aerospace, electronics, construction, HVAC, marine, medical devices, and industrial machinery. Common applications include seals, gaskets, O-rings, bushings, bumpers, pads, mounts, and vibration isolators.

  5. Performance Properties: Rubber moldings and fabrications can be engineered to provide specific performance properties such as chemical resistance, oil resistance, weather resistance, flame resistance, electrical insulation, and antimicrobial properties, depending on the application requirements.

  6. Quality Control: Quality control measures are essential to ensure the consistency, reliability, and performance of rubber moldings and fabrications. This includes rigorous testing and inspection of raw materials, in-process manufacturing, and finished products to meet industry standards and customer specifications.

  7. Environmental Considerations: Environmental factors such as temperature, humidity, exposure to sunlight, and chemical exposure may affect the performance and durability of rubber moldings. Special formulations and treatments may be required to enhance resistance to environmental factors and prolong the service life of rubber components.

Overall, rubber moldings and fabrications offer versatile solutions for a wide range of industrial applications, providing reliable sealing, cushioning, and protection properties in demanding environments. Customization options, performance properties, and quality control measures ensure that rubber moldings meet the specific needs and requirements of each application.
