Pre-series using silicone moulds

Using the vacuum casting technique, it is possible to obtain, by means of silicone moulds, small series of items which have mechanical, aesthetic and dimensional precision characteristics which are very similar to those of the finished product.  The procedure is based on the creation of a silicone rubber mould, starting from an item carried out in fast prototyping.
In the shape obtained in the mould, polyurethane bicomponent resins, which have  multiple characteristics, are vacuum cast.  The use of this system is a great advantage when different pieces have to be carried out, both from an economic point of view as well as for product quality, and where you want to carry out items in transparent material.
The resins which can be used range from rubbers with a hardness from 30 to 90 Shore A, to resins which simulate the most common thermoplastics, such as PP, ABS, polycarbonate, nylon, Vo and doped resins and resins which resist at temperatures up to 180°.  Co-moulding of different materials is also possible.  Prototypes carried out using silicone moulds can be used for tests on the working process, resistance and functionality and allow modifications and improvements to be carried out before going into product manufacturing, as well as being used for marketing purposes ahead of the finished product being ready.  We have different machines at our disposal for vacuum casting, of different sizes, with automatic controls to guarantee constant repeatability and quality. Our experience has led us also to being able to deal with the assembly of the complete unit and to find components which can be bought on the market or which can be made using our machine tools.
