Ventury burner : easy made alumina complex part thanks to Zetamix

Sintering material providers often customize their equipment in order to meet specific clients’ needs.. Before owning a Zetamix system, our client had to supply himself from external resellers. However, obtaining the different parts this way required extensive planning but was also expensive. Because our client knew that additive manufacturing cuts down production time by five and significantly reduces its cost, they rapidly invested in ceramic additive manufacturing and bought a Zetamix kit.


Ventury burner : a common but complex object


Venturi burner is the perfect example of a part that both needs extreme temperature resistance and customizability. Indeed, the shape of the venturi burner will determine the performance of the oven:
The cone angle of the venturi burner conditions the size of the flame and thus the temperature and the oven atmosphere. A broad cone triggers an oxidizing flame, whereas a narrow cone produces a reducing flame. For portable heating equipment, venturi burner is the most common heating system. Because our client produces customized equipment, they need to be able to change the flame characteristics at will. Thus, Zetamix is an ideal choice because it allows industrials to produce customized parts and to choose a material among a selection of technical materials including H13 steel but also Alumina.

Getting a customized part in Alumina : a double constraint


Being more complicated to produce by regular processes than steel, alumina is not often used for this application even though it is the most suitable material. Indeed, this ceramic can withstand temperatures up to 1500 °C. Moreover, its wear and corrosion resistance is higher than that of metal, prolonging the useful life of the part. However, because venturi burners are equipped with internal channels, they are quite complex to produce using conventional ceramics manufacturing processes. Thus, making a customed venturi burner in ceramic is not an option.

Getting out this deadlock thanks to Zetamix

Thanks to Zetamix, alumina-made parts are not more complicated than other material to produce. 3D printing makes it possible to print internal channels, hollowed out parts as well as overhangs. Moreover, by internalizing the process, producing a part require less than a week including printing out the part, chemically debinding and sintering it.



Finally, Zetamix brings a number of solutions that must be considered: it makes the process of fabrication easier while avoiding industrials to order from an external company, cutting down delay and reducing costs of production.
