An improved dental casting investment
European Journal of Oral Sciences, 1980Abstract –In the present investigation a gypsum‐bonded investment is presented with negligible setting expansion and a thermal expansion of 1. 7%. This investment can and should be used without a steel casting ring. In combination with an earlier described die‐spacing technique the new investment facilitates the production of gold inlays and crowns ...

The permeability of dental casting investments
Journal of Dentistry, 1974Gas permeation through investment materials is important in obtaining sound castings by centrifugal or gas-pressure techniques. The equations governing permeation are presented, followed by measurements of the permeability to air of casting investments, comparing different types of material, powder : liquid ratios, and bake-out temperatures.

A modified phosphate‐bonded casting investment
European Journal of Oral Sciences, 1982Abstract – An experimental phosphate‐bonded casting investment with negligible setting‘expansion and a thermal expansion of 1.6%, sufficient to compensate for the solid thermal shrinkage of conventional dental gold alloys and high‐precious alloys for die porcelain fused to metal technique, is described.

Analysis of Casting Defects in Investment Casting by Simulation
2019The present study shows the benefit of using casting simulation software in investment casting to analyze different defects like shrinkage porosity, cold shut, blowholes, and hard zones. In this context, three industrial case studies are discussed. For the first case, 100NB flange is taken as component and simulation is done by considering different ...
