Firstly , we must prepare all the tools we need, then fix the model, establish the pour hole, the pour hole is where the casting material will eventually be poured into the finished mould.Pile up the clay on one side of the mold, this is especially for making the parting line. Dig hole to make latch, it can avoid the dislocation of the moulds.
Secondly,Prepare some liquid silicone rubber, add the curing agent at the ratio of 100:2 or 100:3,mix them evenly. Next, vacuum pump to -0.1mpa,the time should be less than 3-5mins,otherwise,the silicone will cross-link during vacuuming.
