The Yasui Rotating Burnout series features uniform heat transfer, due to the displacement of air created by the rotating shelves, within the flask chamber.
Accurate temperatures ensure a safe burn-out during stone-in-place casting.
The Variable Power Heating System automatically and precisely maintains set temperatures throughout the cycles, (999 Programs, with unlimited Ramps and Holds). This is essential with today’s changing materials that are no longer just injection wax. Today, there is a large range of resins that require different precise temperatures and varying temperature controls to ensure a clean burnout. If the resin is not 100% removed from your investment flask, the unburned residue will contaminate your castings and can eat away at the investment cavities.
Comfortable Work Environment & Eco-Friendly Design
Fume Neutralizing Afterburner
The Afterburner device neutralizes all fumes, odors, and pollution produced during overnight burn-out. The narrow door design creates minimal heat loss.
Minimal Heat Loss from Opening the Door
Unlike wide regular wide-doored furnaces, Yasui RBF machines have narrower doors that greatly mitigate heat loss and temperature drop.
Variable Power Heating
One burnout cycle can be programmed in 4 steps. Optimum heating power is automatically calculated and applied corresponding to each temperature zone so that precise temperature control is achieved. Low power is for the beginning steps and higher power for the ending steps. Such careful control has been developed for preventing flasks from possible overheating at each step.
Platinum and Gold Flask
The RBF 32/21 can reach temperatures up to 950° centigrade and is ideal for casters who cast both gold & platinum.
Easy-To-Access Control Panel
Various information is obtained from the control panel, such as present step no., present burnout temperature inside the furnace, etc.
The burnout cycle will perfectly proceed by the preset time. For instance, if you plan to start CASTING AT 9:00 AM next day, flasks would be ready at 9:00 AM by presetting time today. The maximum preset time is 9 days 23 hours 50 minutes.
4 kinds of different burnout cycles can be memorized on the controller.
Overheat Protection Device Safety For Stones In Flask
The value of precious stones inside the furnace is beyond comparison with the value of the furnace. RBF 21's overheat protection device on the front panel can safely prevent precious stones from overheating. Should the temperature exceed the setting value, the power is immediately shut off.
Measures For Power Failure
On power failure during burnout cycle time under automatic burnout mode, present burnout STEP is memorized. And when power is recovered, the burnout cycle can be automatically restored and started from the step number where power failure occurred.
