When Only the Very Best Will Do

For over 40 years we have been supplying the jewellery and silverware trades in the UK and abroad with the finest castings in precious metals. In recent years we have embraced the huge potential presented by rapid prototyping and have invested in the best software and hardware to ensure that our customers have access to the most up to date technology.

FAQ

We can work with STL, 3DM and SLC files. We find that we get the best results with binary STL files that are exported at a resolution (triangle tolerance) of 0.001
A higher resolution will use more triangles to create the file and give a smoother surface. The downside is that at high resolutions some models will produce very large files. The high resolution model shown here on the right is 1.75 megabytes. If you have problems sending large files a good solution is to upload the file to a site like Hightail.

Please email your CAD file to cad@nf-castings.co.uk.  Files larger that 10 megabytes should be compressed in a ZIP file. If you cannot send large files please consider using a website like Hightail.  We will check the integrity of your model on receipt and notify you of any possible problems before proceeding.

We can cast directly from models produced by rapid prototyping.  The best results are achieved with wax models that have either been milled on CNC machines or printed on Solidscape machines.  Results with resin models can be variable.  If in doubt we can make a cold cure silicone rubber mould of a resin model.  We are experimenting with a new Very Low Temperature (VLT) vulcanising rubber that will allow us to make production vulcanised moulds directly from resin models.

We are very happy to work with customers' own waxes. We can cast directly into the metal of choice or in the case of a hand carved wax that has taken many hours to create we would strongly recommend that a silicone rubber mould is made of the wax before casting. If you want to make a master model we can cast the wax into silver and return it for finishing (or you may wish to make use of our in-house model making facilities).

We have posted a 'Quick Guide to Spruing' in pdf format. You can download it here. We are happy to advise customers on sprue size and position. If you would prefer we can sprue your model for you for a modest charge.

Please use the weight conversion table here to calculate an approximate cast weight from various materials.
