What are Rubber-Plastic Bonded Parts?

Rubber-plastic bonded parts are components formed by bonding rubber to plastic substrates, combining the flexibility and sealing performance of rubber with the lightweight, rigid characteristics of plastic. These parts are engineered for use in dynamic environments requiring vibration damping, insulation, and dimensional stability. The rubber layer absorbs mechanical shock and isolates vibrations, while the plastic base provides structural integrity and design flexibility. A strong and uniform bond between the materials is essential to prevent delamination, stress failure, or leakage during operation, ensuring long-lasting functionality and performance.

DST Rubber manufactures high-quality rubber-plastic bonded parts tailored to specific application needs across sectors. Our bonding process ensures optimal adhesion, temperature resistance, and reliability even under high mechanical or environmental stress.

FAQ

Metal-rubber bonded parts are used in a variety of industries for applications such as vibration isolation in automotive engines, shock absorption in machinery, sealing in fluid systems, and noise reduction in industrial equipment. They are ideal for environments that require strength, flexibility, and durability, such as automotive, aerospace, industrial machinery, and construction.

Metal-rubber bonded parts offer several key benefits:

  • High durability and resistance to wear
  • Excellent vibration and noise reduction
  • Enhanced sealing capabilities in demanding environments
  • Resistance to chemicals, oils, and extreme temperatures
  • Customizable designs to fit specific applications

Common materials include:

Rubber: Nitrile (NBR), EPDM, Neoprene, Silicone, and Fluorocarbon (FKM/Viton®), selected based on environmental and chemical resistance needs

Metal: Steel, Aluminum, Brass, and Stainless Steel, chosen for strength, corrosion resistance, and load-bearing capacity

These parts are made through a specialized vulcanization process, where rubber is chemically bonded to metal using adhesives and heat. This process ensures a strong, permanent bond that can withstand extreme conditions and mechanical stress.

When choosing a metal-rubber bonded component, consider:

  • Load-bearing requirements and expected stress levels
  • Environmental conditions (temperature, moisture, chemicals)
  • Rubber and metal material compatibility
  • Design specifications (shape, size, flexibility needs)
  • Industry standards and certifications for specialized applications
