The art of making... Cufflinks


This week we took a trip North of London to visit our cufflink manufacturer and put into work our new designs for the up and coming season. This is always a very exciting process, particularly because we love to try and challenge the manufacturers when it comes to creating our new and innovative ideas.
We were ever so kindly given a tour of the factory to see how our initial ideas and sketches become finished items through a series of complicated and time-consuming procedures.
Depending on the complexity of the design and manufacturing method, a wax model may first be made in order to understand the technicalities of the construction and to finalise shape and size. These will then be used to create a mould for the cast styles.  Another method of production is stamping; these styles begin their lives here…


Each design with all its intricate detail is carved out onto a piece of lightweight metal, before being transferred to a ‘die’. Each cufflink style will have its own die; a heavy metal block that is used to stamp the design into sheets of metal.

This requires enormous force so the die is clamped into place using a massive vice and the sheets of metal are stamped to produce small individual pieces of metal each containing a perfect replica of the design.

    


The metal stampings are then taken through to a workshop where a team hand trim away the excess metal.  This is called “clipping” and they may also, depending on the design, even add etching detail by hand!




   We then took a peak into the enamelling room. Enamelling is done by fusing powdered glass at an extremely high temperature, usually between 750 and 850°C to metal. The powder melts and fills the hollows in a design that has been stamped out of metal.  When it is cooled it hardens into a smooth and durable glass like layer.

Enamel is applied liberally, often overfilling the detailed metal work and even covering the design. After the enamelling stage the cufflinks are taken to be linished.  This process strips back the excess enamel leaving the metal design showing though.  At the same time the metal is polished and the enamelled cufflink is left looking beautifully clean, smooth and shiny.
