Standard silicone rubber tool manufacturing prac- tices typically require two days for the construction of a flexible tool. A master which is an exact replica of the part to be produced by the tooling is supplied to the tool builder. The tool is then constructed 'around' the master, one mold halfper day, such that it can be assured that the parting line of the two halves of the mold meets exactly. The master is setup in a specially constructed box to form the tool halves. The silicone rubber material is poured around the master to form the first half of the tool. The tool builder adds other devices to the tool half for the purpose of mold alignment, gating and venting. This first half of the tool then requires one full day to cure before the second half of the tool can be poured. Aher the second half of the tool is poured, another full day is required for curing before the tool can be used.
