Combined with different ViscoTec dispensers as a material feeder, the vipro-SPIN rotorspray reportedly enables non-contact, volume-dispensed application of adhesives or viscous greases in bore holes or internal threads. The company reports that the desired amount of material to be dispensed is applied in precisely defined quantities and with repeatable accuracy. The internal contours are wetted evenly and over a wide area. Due to the conical inner geometry of the spinner head, it is possible to use the rotorspray in both vertical and horizontal orientations.

The vipro-SPIN is suitable for low- and high-viscosity lubricants, greases, and anaerobic or other adhesives. A total of four different spin heads is available for a flexible coating of interior cylindrical surfaces with a diameter of approximately 16-50 mm. A plug-in cable, available in different lengths, allows the rotorspray to be easily integrated into various control unit systems.

The vipro-SPIN is required when adhesives or other viscous materials are introduced into bore holes, internal threads, or ball bearings. Another possible application is to make a shaft-hub connection. This is of particular interest in applications such as automotive engineering, engine construction, or general industries such as vacuum cleaner manufacturing.

Volume-dispensed application is possible with the rotorspray, enabling the volume to be precisely defined via the dispenser for continuously uniform material layer thickness. Over- or under-dispensing is avoided by using a volumetric dispensing system instead of time-pressure systems. This is an advantage because the dispensing quantity cannot be precisely defined when using other methods, such as simple outlet valves and pressure vessels.

In addition to single-component materials, the rotorspray can be used to spray two-component materials if required. The adhesive system or other two-component materials are fed mixed to the vipro-SPIN and applied by it to the component. Simple and fast disassembly of the spinner head or the dispenser itself allows uncomplicated cleaning of the components.

“The vipro-SPIN is an excellent addition to ViscoTec’s product portfolio,” said Martin Höpfinger, product manager. “It offers an extra solution and enables dispensing and material coating for internal geometries. In combination with a ViscoTec dispenser, this results in another customer-friendly dispensing system from a single source.”
