Autoclave dewaxing, pressure ramp, wax residue, carbon burn-out and shell firing schedules.
A friend asked me why a particular sprue, regardless of the product assembled, showed no cracks after dewaxing but consistently cracked after firing.
Figure 1: Rough surface on casting due to carbon contamination.Why is this defined as a defect caused by poor dewaxing and inadequate firing? First,
A colleague sent me a photo asking if the casting defect was caused by wax ash. Below are the two images he shared—Figure 1 and Figure 2.
What is the impact on castings if the shell looks like this after burnout? The user sent me two photos, shown as Figure 1 and Figure 2.
A Complex Process The corrosion of silicon carbide kiln furniture in gas-fired sintering furnaces is a complex process influenced by multiple factors,
