Rubber to Metal Bondings

Valley Rubber makes a wide variety of rubber to metal bondings some of which are relatively straightforward but many of which are technical and require careful control of the compound to control the part's torsional and stiffness characteristics.

Valley Rubber makes a size range of these rubber to metal bonded units using from about half a kilo of rubber up to a part of nearly 450mm in length which uses 5kg of rubber. The metal is all prepared in house by carefully trained staff and then bonded up in appropriate presses from our range of equipment. The compound is carefully designed and tested to very close technical limits for both hardness and stiffness. Once made the parts are tested in house for bond strength and stiffness on specially designed rigs and then sent on to the customer for final testing. The very tight stiffness requirements make these challenging parts to make and each part of the rubber to metal bonding and curing process has been carefully tested for it’s appropriateness and contribution to the reliability of the manufacture and service levels of the part.

Mini Suspension Cone Springs

 

These mini suspension cones have been redeveloped at Valley Rubber over the last 6-8 months.

If you are interested in buying these or selling them into the UK market then please contact us on 01443 865010 or at info@valleyrubber.co.uk

The mini suspension cone springs are manufactured in the remade versions of the original 1958 tools and tested using both modern and the original Moulton designed test rigs.

We have been able to source the original rubber compound which is virtually unchanged since 1958.

In order to get a final approval for these mini suspension cones with Moulton Developments, who we have worked with extensively, we have tested the parts on a modern electronic compression stress strain tester and for comparison on the original test rigs which are dead weight time testing machines.

The mini suspension cones have also been tested for stiffness and creep under load at Moulton and conform to the original design brief and test specifications.

In addition to the stiffness testing we have also carried out corrosion testing under high saline and UV conditions to confirm the level of rust creep under the bond and the likely longivity of the part.

The part meets all the original design criteria and can be considered as original parts and not copies.

They are made under our TS16949 quality system and each stage of the manufacture is documented and controlled as we would for any modern part for modern vehicles.
