KeyKeg

The disposable beer keg

The customer’s requirement

Punch Powertrain approached us with a complex problem: an airtight and liquid-tight electronics housing to hold the entire control of the automatic transmission. The original part was made fully of metal, and the aim was to transform it into a plastic version. Another supplier was unable to make the product 100% water-tight and failed on this point.

Our challenge

  • Functionality
  • Weight saving
  • Sustainability
  • Fast delivery times

KeyKeg

Our solution

We took on increasingly more of the product development and thought constructively together with the client about the functionality and efficiency of their product. The secret of our concept lies in the beer valve; we reduced the original 14 parts down to only 4. All the parts are made to enable easy separation. New KeyKegs are already being made from recycled KeyKegs.

The KeyKeg requires a unique tap head which provides the supply of compressed air and discharge of the bag’s contents. We have already developed and produced a new beer keg for a different tap head. Currently we are working on a third cask for another widely used tap head.

Our cooperation

In cooperation with our client, we developed the combined beer/air valve and the structural parts on the bottom and top of the keg. Optimum cooperation has resulted in a combination of functionality, weight saving and sustainability.

‘Alligator Plastics was initially a great producer, especially of the concept I had developed myself,’ tells Bert Hanssen. At the time we were one of the few plastic injection molding companies that offered the 2K injection molding technique. ‘They quickly became more of an engineering firm and I could leave large parts of the development of the injection molding work to them. They know the product pretty much as well as I do, and they have a high level of engineering. For product improvements and new product developments I only need to put a few key words down on paper. The engineers then take it over from me, quickly and efficiently, and come up with smart and innovative translations of my ideas. They regularly also come with good and innovative ideas themselves. That saves me engineering costs in my own company.’ The result of this cooperation is a complete family of KeyKeg products with high added value.
