RUBBER-KU’s Rubber bonded to metal is a manufacturing process that chemically joins elastomer (rubber) to a metal surface during vulcanization, creating a single, high-strength, and durable part. It combines the flexibility and damping properties of rubber with the rigidity of metal, ideal for automotive, industrial, and heavy-machinery components such as mounts, bushings, and seals. 

Key Aspects of Rubber-to-Metal Bonding

• The Process: It generally involves preparing the metal surface (cleaning and applying specialized adhesive agents) and then molding the rubber directly onto the metal (overmolding or insert molding).
• Vulcanization: The bond is perfected during the curing (vulcanization) process, where heat and pressure create a strong, often permanent chemical link, frequently stronger than the rubber itself.
• Structural Benefits: These parts handle harsh environments, resisting shock, chemicals, and vibration. 

Typical Applications

• Vibration Damping: Engine mounts, industrial isolators, and machinery stabilizers.
• Sealing: Bonded seals, gaskets, and hydraulic parts.
• Suspension: Bushings for vehicles and railcars. 

Common Materials and Types

• Metals: Steel, stainless steel, aluminum, brass, and copper.
• Rubber Types: Natural rubber (NR), Neoprene (CR), Nitrile (NBR), Silicone (VMQ), and EPDM. 

This technique, which evolved from complex "black art" processes, is now a highly reliable and precise engineering solution.
