RD Rubber Technology provides its customers with precision solutions for rubber to metal bonding. RD Rubber uses both chemical and mechanical bonding techniques to mold rubber to a variety of substrates including steel, stainless steel, brass, and aluminum.
Chemical bonding – chemical bonding agents assist rubber in bonding to stainless steel, brass, and aluminum. This is often with materials such as butyl, Viton™, chlorobutyl and silicone. Our chemical bonding meets ASTM D429.
Mechanical bonding – molds the rubber to the substrate typically through holes or channels in the substrate to bond it to the part. Any rubber material can be used with this method. This is often used in industrial applications and in many hydraulic products.
Rubber to metal bonding provides the following benefits:
- Ensures that seals are tight.
- Reduces the number components in an assembly.
- Very strong bonds to the substrate often stronger than the physical properties of the elastomer itself.
- Specialized design possibilities.
- Keeps seals in the proper place with proper alignment – avoids human error.
- Perfect for seals or rollers and parts that encounter force and movement.
After molding of bonded metal to rubber parts, our experienced staff has the capability of grinding the bonded rubber to +/- 0.001” to meet your finished part requirements that may go beyond the capability of a molded part.
We also offer the service to anodize your parts after molding.
