Dimensional Accuracy of the Molds Built on Rapid Prototyping under the Influence of the Investment Casting Heat Processes

摘要

It is well known that the Investment Casting processes automatically involves wax and molds as a first step. During the wax injection there are heat transfer between the wax pattern and mold. The mold is getting heat and due to this, the dimensional accuracy suffers in the not desirable way. Injection molding has been the most popular method for making wax products due to high efficiency and manufacturability.
