The client came to us already in the process of designing a lightweight and durable violin case with the intention of having us produce the top and bottom interior liners of the case, which were to be vacuum formed out of a thin plastic material.  Recognizing that the existing design was not suitable for thermoforming, we began to modify the design of the plastic liners, and also worked to educate the client on why the changes were needed.  With a good relationship established, we were able to work with the client to account for the design requirements and the changes during development, and to ensure that the plastic liners would meet the part to part requirements of the the various interal OEM components and the external carbon fiber shell.

Once the design modifications were completed, we produced the molds required to thermoform the plastic liners, as well as the 5-Axis CNC trim fixtures used to trim those parts to their final shape.  The trim patterns in particular required a lot of time and attention due to the numerous tight tolerance slots and holes for the many interal components.  Once produced, the liners were sent to be flocked (or sprayed with felt), giving the parts a soft texture suitable for contact with something as valuable as a Stradivarius violin.  The parts were then incorporated into the case assembly.

The result is the Petrus Violin Case – a light weight durable carbon fiber exterior case with an aircell padded interior, equipped with a hygrometer, multiple storage pockets, and of course storage for a violin and bows.
