Quick casting

Interesting new manufacturing technology that i found... quick casting for limited series. This method enables metal prototypes to be made in a matter of hours. The 'limit' on the moulding is actually not that limiting 1,000 to be exact, so unless you wanted to produce your little zinc part en mass then there wouldn't be a problem. The limitations are that the metals used need to be of a lower melting point such as zinc, pewter and lead.

This is how it works....

"The technique's secret lies in using a silicone mass in the form of sheets that soften when heated and harden when cooled. Two sheets are placed on individual, rigid steel supports that prevent the edges of the silicone from deforming. After the silicone is warmed to between 100-180 degrees Celsius, the model is placed between the silicone sheets and the steel supports pressed together. An impression of the model is left in these silicone sheets. After cooling and hardening, this mould is split and inflow channels, as well as cavities for reducing pressure during the casting process, are prepared. The mould is then ready to be used for die-casting new models or jewellery and industrial components that will be copied and replicated. "

So this means that only one form needs to be made in a hard material, then it can be casted again and again.

Interesting process, but not sure if it is beneficial to my project.
