Technology/Capabilities

PreciCast Process is same as Lost Wax (Investment casting) process.

First a foam pattern is moulded using Expandable Polystyrene (EPS) or co-polymer which is an exact replica of the desired casting. Runners and risers are attached by glue to the foam pattern and a cluster is made of one or more number of foam patterns. The cluster is then coated multiple times with permeable refractory slurry in a homogenous bath by dipping.

Then the dry coated cluster is put in to a furnace where it is baked at very high temperature. Because of baking the foam gets vaporized and shell becomes stronger. Now the hollow shell is invested in a flask with sand, then vibrated to compact the sand around the cluster in the flask. Molten metal is poured through the pouring cup. On solidification of the metal, the sand is drained off the flask and the tree is removed. The castings are knocked out from the metal cluster, fettled and finished before they are shipped out.
