Abstract

In the case of a method and an apparatus for producing parts with high quality surfaces using a mold and curing resin, such as epoxy resin, the first step is to place a workpiece blank so that there is minimum gap between it and the mold. Then resin is introduced into the gap in a non-separating flow utilizing capillary forces in the gap. The epoxy resin then cures and the workpiece coated with such epoxy resin is separated from the mold.
