Performance characteristics and properties

Rubber-metal composite parts unite the advantages of hard and soft components in a single component. Rubber provides flexibility and damping, while metal offers stability and load capacity. The permanent, inseparable bond creates highly functional components with extended service life.

At a glance:

  • Superior mechanical stability through metal carrier parts
  • Elastic properties for damping, sealing, and vibration isolation
  • High load capacity and long service life
  • Permanent, inseparable rubber-to-metal bond
  • Reduced number of components and reduced assembly effort
  • Optimized load distribution through engineered component geometry

Do you have questions?
We have answers!
Metal composite parts combine stability and elasticity in a single component, yielding durable and robust solutions with reduced assembly effort.

We process steel, stainless steel, aluminum, brass, etc. Specialized alloys can be utilized as required. Selection is based on load parameters, weight constraints, and corrosion requirements.

A permanent bond is formed through specialized chemical bonding systems and vulcanization processes.
Yes. We develop application-specific combinations of rubber and metals tailored to your technical specifications.
With our in-house toolmaking, metal parts manufacturing, and Express Service, we deliver prototypes in 2 weeks and start series production in 4 weeks.
Vulcanization creates a permanent, inseparable bond between rubber and metal through controlled temperature and pressure. This bond demonstrates significantly higher durability, robustness, temperature resistance, and dynamic load capacity compared to an adhesive bond. In failure analysis scenarios, cohesive failure within the elastomer material is more commonly observed rather than adhesive interface separation.
