How an Inert Gas Flash Dewaxing System Improves Casting Quality
Also, when you have a very accurate investment casting furnace operation, every single variable will affect the integrity of your final part - but one that will have a more immediate impact on that integrity and therefore, could change your results is dewaxing. This is why Laxminarayan Technologies has carefully developed this important stage of the process over almost 40 years. The Inert Gas Flash Dewaxing System was not developed in a laboratory, it was designed directly from experience on the foundry floor with the casting companies who value well-defined consistencies, pure wax reclamation, and a minimum of shell failures.
Dewaxing Done Right: The Laxminarayan Approach
Conventional steam autoclaves are effective methods of de-waxing but have drawbacks to consider; thermal shock to the patterns, moisture infused wax, and large amounts of energy required for the cycles. We have developed an inert gas flash de-waxing system that replaces this complex process with a single sealed chamber. We rapidly heat the patterns with nitrogen or argon to provide a progressively though oxygen free (inert atmosphere) while maintaining the integrity of the wax chemistry and ceramic shell. In one integrated process you have the following performed; de-waxed, recovered wax, and pre-burned out.
Why This Matters for Your Casting Quality
A broken shell means more than just needing to do the work again; it can lead to delays in delivery of materials wasted and ultimately an unhappy customer. But here's how our system provides direct support for producing higher quality castings:
- Using low controlled temperature heating, there are no spikes in steam pressure causing stress on the shell creating microfractures.
-When the wax does condense, it is done in a dry, inert environment without any moisture present thereby allowing the wax to be ready for immediate use without any drying time.
- Complete evacuation of the pattern allows for all parts to drain completely, which will reduce the risk of metal penetration through the buildup of material inside the pattern.
- A prototype-friendly process works with SLA, SLS, FDM and LOM patterns, in addition to more traditional wax based methods of rapid prototyping.
The foundries that use our system are typically able to recover at least 80% to 90% of the high purity wax used, while consuming up to 40% less energy than when using traditional methods. That is more than being efficient, that means compounded Quality Assurance.
Real Results from Real Foundries
Our long-time partner is a supplier to the aerospace industry and they adopted our inert gas flash dewaxing system to resolve the issue of returning to their operation due to thin-wall component shell cracks. In just three production batches, we have seen: o An overall reduction of 22% in defects related to shells o A reduction by almost 50% in preparation time to reuse wax o An obvious decrease in the cost per batch for energy use
These are not just theoretical gains. These are results of creating equipment with consideration of both the science of metallurgy and the day-to-day realities of running your business.
