Die Stamping - Cloisonne - Hard Enameling
The production method for manufacturing coloured cloisonne or hard enamel lapel pin badges is die stamping. The techiniques used for custom logo cufflinks is very similar, in the fact both products would be die struck with your logos profile including all raised / recessed surface detail. The only difference for enamel pins is we would add an outline to your logo to form an outer edge for the enamel to be encased. All enamel badges and cufflinks would then be baked then left to set hard, ground down, buffed ready to polish then gold or silver plated to suit.
Laser Cutting - Engraving
The production techniques used to manufacturer some logo designs are Laser cutting, (also known as laser profiling) and Laser Engraving. These production processes are incredibly flexible. We can cut and engrave virtually any logo design in a variety of flat metal, wood and acrylic sheet materials. High powered Industrial Lasers are used to cut different materials, and specialist lasers for the engraving. Digital tooling enables low cost, rapid turnaround of prototypes and mass production. Design modifications are accommodated quickly and inexpensively. Tool set up fees range from £150 for laser cut metal designs, (if your order is more than £150 the set up fee is discounted.) Our customers CAD / design data is imported to allow cut simulation and sheet layout optimisation, ensuring we have a quick response to enquiries.
A hole cut with a laser has an entry diameter minimally larger than the exit diameter, creating a slightly tapered hole. The minimum internal radius for slot corners is 0.2mm. Unlike stamping, the normal design rules regarding minimum wall thickness, minimum hole size (as a percentage of material thickness) does not apply.
The minimum hole sizes can be as low as 20% of material thickness, with a minimum of 0.25mm for up to 1.9mm material. Burrs are virtually eliminated and are insignificant when compared to those produced by shearing or blanking.
Etching is used for bulk quantity orders where your design requires intricate surface details. If your logo is more than 1.5mm thick your surface etched design will need to be laser cut after the etching process. If your logo is made from 1.5mm thick metal and below we can surface etch details and etch all the way through the parts of the metal you don't want to keep. The maximum depth of surface etch we can achieve is 0.3mm, this is why etching is not suitable for hard enamel pin badges or cufflinks as the enamel needs to have a deeper recess that you can do with die stamping. Etching is best suited to stainless steel and quicker manufacturing lead times, resulting in more cost effective unit costs.
Precious, Non Precious Metal Lost Wax Casting
We commonly use traditional jewellery casting techniques to produce more complex logos from silver and gold. In most cases we will hand make a master proto type of your logo then make a rubber mould for reproduction, if you had an object than you would want us to replicate then we could use a cold rubber mould to eliminate any potencial damge to your item. Your logo is then lost wax cast into your desired metal alloy. A one off mould charge of £25 applies.
CAD Modelling Design - Rapid Prototyping
Another popular more modern solution we offer our customers is Computer Aided Design (CAD) which has revolutionised the way we can design and manufacture jewellery.
By using CAD software we are able to create 3D models of your logo which will be in turn rapid prototyped into your desired metal alloy. Once your logo has been prototyped Thomas Nayler skilfully hand finishes every piece to perfection with any stone setting needed. With over 10 years in the jewellery industry and being Hatton Garden trained you are guaranteed a quality product to show off and market your branded products.
From your idea or sketch we can produce a Bespoke CAD model to your exact specifications. A photo realistic rendered image will then be emailed for your approval. Once the design has been finalised we will rapid prototype the CAD model and cast in your required alloy.
Finished Components from One Source
Combining Laser Cutting/Etching/Casting/Rapid Prototyping with other in-house traditional jewellery manufacturing processes and finishing techniques means we can provide our customers with finished high end logos that are quality checked at every stage enabling you to reduce your supplier base and save valuable time, money on marketing. All of our high end logo jewellery is made in the UK, large orders of cheaper products may be outsourced to our reliable trade contacts that we have build up trust with over the years to offer you peace of mind.
