The finished veneering ceramic is inserted with a filling nozzle into the plastic vial. Exactly 50 grams pass through a funnel into each container. A balanced scale controls the filling quantity. The full vial is now automatically sealed with a plastic lid until it is manually reopened for use in the dental laboratory. In the end, each technician on site must know what kind of veneering ceramics he or she is dealing with and in which shade. This means that the journey of the ceramic vial is far from over: Now it awaits the corona treatment, which involves an unexpected turn on the conveyor belt. Directly above the plastic lid, two electrodes generate a spark, which creates a controlled plasma flame. The flame is blown onto the lid surface. This opens the plastic pores, which can absorb color and thus the lettering via pad printing. "If we did not do that, the color would not hold. Everything runs completely automatically." After half an hour, the pores close again. Then the lettering is securely integrated in the plastic. The fully automated journey of the vial continues on. Pneumatic cylinders now fix it securely to allow the appropriate imprint on the body of the vial as well. Article name, shade and part of the article number are added permanently on both the lid and body of the vial. As a result, the veneering material can be properly classified in the laboratory without any chance of them being mixed up. Using the article number, each production batch can be clearly traced. This process requires a lot of effort, but it pays off. The small lettering provides a big benefit.
