Industrial Tests on "Formowax" Pattern Wax Under Investment Foundry Conditions

Kurdziel P., Dydak A., Robak I., Kubosz G.

Archives of Foundry Engineering

2012

Vol. 12, iss. 2s

41--44

Soft pattern waxes used in investment castings are a mixture of paraffin, stearin and minor amounts of ceresin, polyethylene wax and other natural and synthetic waxes. Nowadays foundries conduct the process of pattern wax formulating on their own. However, instability of the ingredients parameters can have a negative impact on the technological characteristics of the obtained waxes. The paper presents the results of tests on applying a ready-made "FORMOWAX" pattern wax developed by Polwax Sp. z o.o. Application of the reference wax was tested for standard patterns made in Specodlew investment foundry.
