Our moulding services cover many types of moulding technology however almost all moulds created in the modern era are RTV – liquid silicone rubber moulds. 

Mould designs are created dependent upon many factors, but always with the intention of maximising quality for a given model and simplifying finishing. With this approach you can have the most saleable and easily finished models, with the lowest possible finishing cost at a reasonable casting fee – this combination almost always keeps our clients very competitive.

Black Arts can mould objects from organic pieces to metal components. Waxes and certain rapid prototyping resins are often recommended to be  moulded before casting to offer an ‘insurance policy’ when casting a master, urgent job or anything that has a high prototyping cost.

Our castings are guaranteed for satisfaction within the constraints of what is possible with regards to your model and the standard price point services offered. If you’re not satisfied with a casting a free replacement casting service is always available. Please be aware that singly the most significant driver for a quality casting outcome is a model that has been designed for casting.


Finishes available



Bright finished (standard service) either chemically stripped or magnetic pin polished alloy dependent.

Plating finishes available – hard gold plating 2 microns/Vermeil as standard, greater depths on request
