Wax Casting Burnout Cycles. The next step of the burnout is 1350 degrees F. This is where the investment is cured. Most investments do not need to exceed 1350 degrees and should never reach 1500 degrees F. At 1500 degrees, the gypsum binder begins to break down and discolor the metal.
This is just based on what I've read so far, but you concievably can use your foundry as a burnout oven. However, it can be tricky; as foundries have a bit less temperature control than a proper kiln.
If the oven is full of flasks, there will be less effective airflow per flask. Attach an oxygen generator to the oven to increase the airflow. Maximize the airflow and ventilation during burnout. Adjust the burnout schedule for temperature fluctuations as a result of increasing airflow.
Bio-Materials and Prototyping Applications in Medicine The completed wax pattern is then encased in a heat-resis- tant investment mold with the wax pattern burned out in an oven. This process, also called the ' lost -wax technique' is very labor intensive.

Put a fillet of wax where the sprue is attached to the model. Secure the sprued model to the tree. Keep the sprue for the model as short as possible. The sprued model can be attached with "sticky wax" or by using the hot needle again. Put a fillet of wax where the model sprue and the tree meet.
Fiber Burnout Furnaces Energy efficient furnaces for jewelry and ceramic. The firing chamber is a one piece ceramic fiber shell with embedded elements. For greater thermal efficiency the space between the steel case and the fiber shell is packed with extra fiber insulation. More Info ›.

The 5 hour burnout is perfect for doing just a few smaller flasks. My ramping schedule looks like: Hour 1: 300 degrees, Hour 2: 700 degrees, Hour 3 and 4: 1350 degrees, Hour 5: 1000 degrees - and hold. Hold temperature may vary depending on the metal. For larger flasks, larger waxes, natural materials or a really full kiln, up to a 12 hour burnout.
However, it can be tricky; as foundries have a bit less temperature control than a proper kiln. To minimize the possibility of shattering your investment, you need to start by heating it slowly and then ramping up the temperature until your wax has fully pyrolyzed. The instructions you linked for building a kiln are pretty basic.
The burnout oven is then used to melt out the wax figure from the investment mold, while bronze ingots are placed in a crucible and melted in the pot furnace.

Mar 17, 2010 · I recommend letting enough days pass to fully dry out your mold material (mfg will have curing info) before wax burnout or, using an oven etc., at less than 200 degrees F to cure the mold without burning out the wax. Make sure you leave oven door open a crack. You do not want a weak mold when you pour your hot metal which is usually above 1500 F. So, any moisture left in the mold material when you do your wax burnout will be harmful to the integrity of the mold, regardless of whether you can
Once the flask is ready - it goes in the kiln and starts the burnout process. Burnout times are anywhere from 5 - 12 hours. The 5 hour burnout is perfect for just doing a couple of small flasks.
Lindberg's investment casting mold preheat and burn out box furnace is designed for maximum efficiency and ensures cleaner shells with less smoke because of its unique automatic air injection system. This horizontal furnace operates at maximum heat-up rates and minimum fuel costs.
With a stainless steel, sloping floor leading to a drain, this oven is designed to allow molten wax to be collected and later re-used. Burn-out oven Designed to allow a good flow of air through the chamber in order to facilitate the combustion of any residue after de-waxing, the heated exhaust is provided to ensure that all waste gas is combusted efficiently.
