Mould Making for Jewelry Manufacture
Gold and Imitation Jewelry
Fortisil RTVs are particularly used for and suited to the mass production of gold and imitation jewelry.
The complex requirements of the industry are covered by our addition cure RTVs which:
Reproduce details up to 2 microns
Give more flexibility for the designer as they see their luxurious, complex designs turn into reality. Especially suited for ‘micro pave’.
Experience no shrinkage
It is very important not to have any dimensional variation to avoid wastage, especially when it comes to gold.
Are low viscosity
Makes the RTV easy to mix, pour and vacuum, thus reducing mould rejection.
Have Fast setting times
Reduce delivery times and increase production.
Have High tear strength
Moulds last longer, giving more castings per mould, thus making it more cost effective for larger volumes.
Showcase Ideal hardness
Hardnesses between 20-40 ShA are ideal to demould complicated wax pieces without damaging them.
To see whether the casting material has spread sufficiently as well as for ease in cutting the mould.
Our RTVs have been perfected following inputs and advice from world renowned master goldsmiths.
