EASY Casting - Pear-Shaped Casting Sprues with Reservoir
Plastic-free wax auxiliaries for sprueing, casting and pressing of crowns and bridges made of precious metal to palladium base (Ø 5,6,7 mm) and from palladium base to non-precious metal (Ø 7,8,9 mm) alloys based on cobalt-chrome (CoCr). The casting pins are CAD designed and have new optimized shapes. The inlet channel is square, because during the casting process the liquid melt (in motion) takes on a drop shape, so air (gas) can escape from the muffle via the free corners. This prevents turbulence, the melt can flow in faster, results in more homogeneous casts, smoother surfaces and a better fit. The lost heads of the casting pears have a nozzle shape, serve as a melt reservoir and are suitable for safe re-suction until the final solidification of the melt.
Due to the tapered shape towards the object (funnel or nozzle shape), the melt is accelerated many times over during the casting process (law of continuity). The casting pins are pinned on the front waxing point by dental technicians with a special connecting wax by washing the tip around the object. The EASY connecting and blocking wax is sticky in the liquid state and facilitates the application of the sticks in the dental laboratory without constantly falling off. After solidification at room temperature, this wax is hard, dimensionally stable and prevents distortion of the wax model when it is removed.
If necessary, you can cut off the square inlet, use the "lost heads" as melting reservoir and pressure compensation reservoir. EASY Casting is suitable for all casting techniques, sprueing techniques as well as for centrifugal casting & vacuum pressure casting for casting. The organic composition burns ash-free without leaving any residue and is suitable for printed 3D dental objects, metal casting, as well as for veneers made of pressed ceramics.
Advantages:
* Suitable for all dental alloys
* Excellent scraping and modelling properties
* Homogeneous castings, void-free and smooth surfaces
* Flow-technically ideal nozzle shape, prevents turbulence
* Organic composition burns without residue - ceramic pressing technique suitable
