Rubber to Metal Bonding

Providing Strength and Flexibility in One Component

When it comes to creating components that require the strength of metal and the flexibility of rubber, rubber to metal bonding is the solution of choice.  These components, available in a wide range of shapes and sizes, are commonly used in applications such as valve assembly, shafts, and rollers. 

The rubber to metal bonding process is a complex one that involves mechanically bonding the rubber element to the metal insert during the moulding process.  By combining all components into one part, the end result is technically superior and more consistent than if separate components were used.  Additionally, in many cases, it is also the most cost-effective solution. 

Preparing the Surface for Optimal Bond Performance 

Before we can use any rubber to metal bonding adhesives, the surface must be prepared to ensure optimal bond performance.  The metal surface is degreased using solvent or an alkaline cleaning process to remove any oils, and any rust is thoroughly removed. 

The component is then kept in a clean, low-humidity environment to prevent further contamination.  It is handled using gloved hands to prevent natural oils from skin coming into contact with the metal. 

Using Heat-Activated Adhesive for Rubber to Metal Bonding 

A heat-activated adhesive is used to provide the rubber to metal bonding.  The adhesive is applied using a spray application, and once complete, the metal is ready for production. 

During the production phase, the metal insert is placed into the cavity of the mould, and the normal rubber moulding process begins.  The heat from the moulding process activates the adhesives on the metal, bonding the insert to the rubber around it. 

Quality Control and Testing 

Every rubber to metal bonding job we complete undergoes a rigorous quality control and testing phase to ensure that each part is produced to the very highest standards.
