Gravlund Industrigummi offers bonding of rubber to rubber or rubber to metal, which can be a fast and cost-effective alternative to traditional vulcanisation.
Bonding does not require high temperatures or pressure during the process, making it a gentler method for the customer’s component, which retains its shape and dimensions throughout.
In some cases, special fixtures may be required, but there is no need for investment in moulds. However, only one item is produced at a time. Handling and curing time is relatively long, which makes bonding particularly suitable for small series or prototypes.
Today, there are effective adhesives available that are suitable for a wide range of rubber compounds. Their adhesive strength is in many cases comparable to what is achieved with traditional mould-based vulcanisation.
Modern adhesives have high bonding strength and are effective on many types of rubber compounds. In many cases, the adhesion achieved is comparable to that of traditional vulcanisation.
| Property | Bonding | Vulcanisation |
|---|---|---|
| Strength | Often lower | High and consistent |
| Heat resistance | Limited | Very high |
| Durability | May degrade over time | Very stable over time |
| Design flexibility | High | Limited by mould and tooling |
| Equipment requirements | Low (no mould or pressure needed) | High (mould, heat, pressure) |
| Production time | Long (due to curing) | Fast in mass production |
If you need assistance in determining whether bonding is the right solution for your project, our technical team is ready to advise you.
