By means of the very latest technique on so-called carousel-type machines we are manufacturing carpules with the highest quality standard. For hygienic reasons the glass tubes to be handled will be kept in a closed loading system. A robot guarantees the exact feeding.

For the manufacturing of one carpule there will 12 stations be needed. After the cutting of the lower, melted tube end, the roll edge, neck and the shoulder will be formed by means of a forming roll, after having been heated by a flame. Then it will be cut to the preset length and the stopper mouth will be melted. The exact cutting of the inserted glass tubes will be done by scoring the glass surface and by a cold/heat shock treatment. Thus, a clean, exact cutting edge will be reached.

By using the latest measuring techniques, the carpules will be detected by a camera which determines the total geometry, such as glass diameter, roll edge diameter, roll edge height, neck diameter, neck height, shoulder bevel, total length and slanting bottoms. The faulty parts will be rejected. All performance data will be memorized and give most precise information about the further production process. These printouts are also of course available to our customers.

After this production step the carpules will be printed according to the customer’s specification and relieved in the oven at more than 600 ° Celsius, and the colour will be burned in. At the end of the production belt the carpules will be made ready for despatch and palletised in a nearly dust-free packaging room.
