Cold Forging Basics

Back  Blog Home

Riveting is one of the oldest forms of fastening.

Solid rivets have been found dating back to the Bronze Age (ended 800BC)

You will have seen rivets hidden in plain site on bridges, ships, Aircraft and Trucks to name a few common applications.

They are also common throughout your home, if you have double glazing then you will probably have our rivets in the hinges.

Rivets are formed by a process called Cold Forging, this process produces no waste as the head of the rivet is formed by upsetting the shank of the rivet. This ensures the grain flow of the material remains in-tact thus strengthening the fastener.

The rivets are inserted in the material to be fixed together and “set” by deforming the end of the shank of the rivet to product a permanent fix

 

The more popular, semi-tubular rivet is set in a similar way but require a lot less setting load and provides a “Clinch” fix which pre-stresses the material

Many engineers are unaware of the advantages or even the function of rivets, tending instead to fall back on threaded fasteners which are more widely available.

The most recent development in Riveting is the self-piercing rivet, where you do not need a hole in order to rivet two materials together. This process is now commonplace in state-of-the-art automotive manufacturing plants. JLR being pre-eminent in this regard.

 

The process used to produce these fasteners has been developed in order to use the same manufacturing technique, Cold Forging, but to enable finished components to be forged outright, with the same benefits, no waste and a very strong structural integrity.

We are happy to help customers or prospective customers with any queries that may have regarding riveting or cold forging. We have recently helped a number of companies by producing and riveting prototype designs for them.

We have been in this business since 1939, over that time we have provided innovative, low cost solutions to many fastening and cost reduction requirements, thrown at us by our customers.

Brexit: No Deal

October 2018

 

Impact of Clevedon Fasteners Ltd and Clevtec in the event of a no-deal outcome to the EU withdrawal negotiations

We are beginning to get letters from customers asking what our position will be in the event of a no deal Brexit

The following seeks to give the reader a flavour of our view on the subject

Clevedon Fasteners Ltd use sub-contractors for Heat Treatment and Plating processes who are predominantly local to us and all are in the UK. These entities are relatively immune to the effects of a no deal scenario as their main drivers are Gas (heat treatment) chemicals and Electricity (plating plant). We have our own tool room but occasionally sub contract tooling. Again these companies are not expecting a problem as they have well established workforces and there their material stocks are high

The only product we purchase from outside the UK is wire which we use to manufacture our parts.

There has been no suggestion in the literature available that either the UK or any of the EU27 are expecting to cease work when we leave the EU. The main focus has been around potential tariffs, added paperwork and delays at the border.

We sell all over the world and so we are used to paperwork

We hold relatively high (3 months) stock of fast moving raw material

We source our wire from the UK, the EU and non UK companies

In the UK, British Steel have just upgraded their rolling mill with a £50m investment and we can switch EU product to non EU suppliers relatively easily if we need to

The other big unknown is the exchange rate and in the event of a no deal the GBP will fall significantly in value in the short term, but so will the Euro, therefore it will be pretty much the same, but lower. The fundamentals of the UK economy are sound and any hit will be short lived as it was when the UK voted to leave the EU

We are in the relativity enviable position of not having to purchase anything from outside the UK for approximately 10/12 weeks, during which time the effect of a no-deal scenario will be well on the way to being resolved.

Not wishing to stray into the political arena, but no matter how much of a hash the politicians of all complexions make (and are making), in the end it all boils down to trade and pounds, shillings and Euros.

As things stand I believe we are well placed to cope with the short term disruption and will be able to continue to provide the excellent service our customers have come to expect

As more information comes into the public domain that significantly changes our view I will update this notice

Yours sincerely
