Molded Rubber Seals & Gaskets

Molded rubber seals & gaskets, also known as custom-molded seals or compression-molded gaskets, are precision-engineered components manufactured through compression, transfer, or injection molding processes. These parts are designed to create reliable sealing under pressure, heat, and chemical exposure. Molded rubber seals are essential in applications where dimensional accuracy, sealing integrity, and long-term durability are critical.

Okin rubber’s molded rubber seals and gaskets are made from high-performance rubber materials such as silicone and Viton. They are widely used in automotive, aerospace, electronics, medical, and industrial applications for fluid sealing, vibration damping, or environmental protection.

Whether you need complex-shaped molded seals or high-volume gasket production, our molded solutions offer excellent resilience, resistance to deformation, and leak prevention for:

  • Hydraulic systems
  • Engine compartments
  • Valves and pumps
  • HVAC systems
  • Electric enclosures
  • Industrial machinery

Manufacturing Process of Molded Rubber Shock & Vibration Parts

Our shock and vibration components are manufactured through compression or transfer molding processes. These methods allow precise control of material flow and cavity filling, ensuring consistent mechanical properties, dimensional accuracy, and long-term fatigue resistance.

 

Importance of Rubber Shock & Vibration Control

Vibration and shock can lead to mechanical failure, increased wear, noise, and loss of accuracy in sensitive equipment. Molded rubber parts isolate movement, dampen impact energy, and stabilize assemblies. They protect both equipment and personnel by reducing transmitted forces, especially in high-speed or high-load applications.

 

Features of Molded Rubber Vibration Parts

  • Excellent vibration isolation and noise reduction
  • High resilience and damping performance
  • Resistance to compression set and fatigue
  • Withstand oils, solvents, heat, and UV
  • Custom sizes, shapes, and durometers available

 

Types of Molded Rubber Shock & Vibration Parts

Silicone Vibration Isolators Silicone rubber offers excellent flexibility and damping over a broad temperature range. It is inert, UV-stable, and suitable for electronic, medical, and high-temperature applications.
Viton Rubber Mounts Made from premium fluoroelastomer, Viton rubber parts resist aggressive chemicals, fuels, and high heat. They are ideal for automotive, aerospace, and chemical machinery applications.
Custom Molded Dampers We can manufacture fully customized vibration isolators in any geometry—cone mounts, bushings, bumpers, feet, washers, and more—based on your 3D drawings or usage requirements.
