Shell Building

Over the years, however, a number of misconceptions about shelling QuickCast patterns have emerged. For the most part the same shelling method can be used for QuickCast patterns as is used for normal wax pattern assemblies.  In general, existing shell building practices can be used successfully to shell QuickCast patterns. Most foundries use the same shelling method for QuickCast patterns as they do for their normal wax pattern assemblies. However, added shell thickness is a good idea to strengthen the shell for the added forces typical when burning out QuickCast patterns.  Also, for very large Quickcast patterns, where buoyancy may be a problem in dipping in the slurry tank, it may be preferable to flow-coat the slurry over the pattern assembly.
