Automotive dreams perfectly dosed!

preeflow dispenser as part of Porsche’s Spyder 918 production and guarantor of perfect bonding applications.

The Porsche 918 Spyder combines hybrid technology and innovative design with driving fun of a racing car, but with eco-friendly consumption. Revolutionary components, high recuperation performance as well as a fancy racing design: This combination makes a futuristic supercar.

But what has the eco-PEN to do with the eco-car of Porsche? Precision, accuracy and the high-end-technology made in Germany – these are, for example, characteristics both share. And the dispensers by preeflow especially show their strength in dosing adhesives. Also in the Spider production: Inside the electric motors, magnets must be stuck to the rotor encasement. The magnets are glued in with a special resin. The resin is applied precisely by the eco-PEN. The accurate application is very important: To ensure weight is evenly distributed. Essential for this application was the easy adaption of all process parameters to each other, like fluid flow and speed. Not having much space inside the rotor and the application ot the material onto a vertical surface, were no challenge for the dispenser by ViscoTec.

The eco-PEN dispenser offers many advantages for the production line:

  • High accuracy and repeatability, to reach an evenweight distribution in the motor system.
  • Constantly high quality applications.
  • Simple, as well as linear adjustment of speed and volume rate.
  • Easy integration to a limited space.
  • Application to a vertical surface.

Out of a futuristic concept, Porsche created the eco-green 918 Spyder. A hybrid car with low thirst for fuel and a high voltage electrical system with the driving dynamics of a performance racing car. With its 887 PS, this car speeds up from 0 to 100 km/h in 2,6 s having a CO2 emission of only 70 g/km – even under the range of a small car. Porsche breaks the boundaries for style, performance and technology regarding hybrid drives. After a limited edition of 918 pieces Porsche 918 Spyders Porsche decided to continue the hybrid concept for future sports cars with the 919 Spyder.

The 918 Spyder is still a pioneer in the business of e-mobility, to show that an economic drive does not exclude the driving fun of a racing car.

For ViscoTec and especially for the trade mark preeflow it is a pleasure to be part of the production of the high-end hybrid cars by the German automobile manufacturer Porsche. The preeflow products can be found in many future oriented projects. In the fields of e-mobility, battery manufacturing or in the classical electronic industry, the dispensers are in continuous use.
