Catheter manufacturing in perfection

By the endless piston principle, on which all dispensers at Viscotec are based, a continuously volumetric dosing is possible. Thus the process is gentle and with low shear force on any media independently of viscosity. The direction of flow can be reversed, this leads to a clean cut-off string and dripping of the medium is prevented.

preeflow® dosing pumps operate in the micrometer range with an absolute accuracy of +/- 1. This means that the smallest amounts of adhesive can be applied to the tubes, always with constant volume. This quantity can be adjusted so that after attaching the balloons, sleeves, connectors, etc. enough material is available to firmly adhere the pieces together, but so little that no excess material is squeezed out. A better dosing in an environment that demands absolute cleanliness and sterility is not possible. A further benefit is the easy integration of preeflow® products. The dosing pumps are designed in such way that they can be used in any production process - from simple manual workstations to fully automated production line. The required hardware is assembled as required. The user must only connect to the existing equipment, calibrate once and already the dosing pump is ready for use. It is possible to start signals for dosing directly via the associated controller, via a foot switch or via a master control unit to. Unlike piston pressure sprayer, the use of this equipment means that the hands of the workers are free for bonding the catheter. So the job is done faster and cleaner, and more catheters can be manufactured in the same time. After these unique advantages over conventional piston pressure spraying, it is important to pay attention to the cleaning of the dosing pump regarding to the preeflow® dispensers. This is very simple and fast. Thus equipped, there`s nothing stopping an automation in the production catheter. In this way with the same manpower a bigger number of catheters can be manufactured to keep covering the increasing demand. At the same time, the material consumption is optimized and reworking are eliminated, which contributes significantly to the cost reduction. Repeatability and process safety can be guaranteed with preeflow® dosing.
