Special geometry can only be produced with ceramic 3D Printing
For a highly automated bonding procedure metal dosing needles have been used so far, these are components for the exact dosing of an highly viscose adhesive. Here, particularly durable and wear-resistant components are needed. Because downtime of production lines causes enormous costs, the service life of the installed parts is of great importance.
CERIX developed in close cooperation with the manufacturer STIWA an alternative dosing needle made of Technical Ceramics with the 3D Printing.

The dosing needle has a unique internal geometry: an internal cone that is curved and tapers down from a few millimeters to 0.8 mm. It would not be feasible using conventional production methods, however, 3D-Printing can produce the component in all of its complexity. The highly accurate CERIX production method guarantees the diameter at the nozzle outlet with its required roundness without subsequent prcessing.

Exact surfaces for the correct flow behavior
To convey the adhesive accurately and continuously, it must flow through the bore with little friction. Since it is an internal cone, no subsequent processing of the surface can take place: The manufacturing process must already have the required accuracy. Again, this requirement is not a problem for the 3D-Printing process of CERIX.

`…Only with the ceramic 3D Printing from CERIX we could realize the special geometry paired with the high demands on tolerances and surface of the dosing needle. Therefore CERIX provides the best and most economical solution for us…´
