For applications involving airtight chambers Temponik would normally produce the prototypes using the TempoCast method, which is very well suited to such applications. In this case, however, fast delivery was more crucial.
Bosch Rexroth Fluidtech SAS in Bonneville, France requested a number of functional prototypes of an aluminium part, which among other features should comprise a pneumatic chamber.

The core requirements were the following: The chamber should be airtight, the part should fit accurately into a mechanical fixture, and the exterior of the part should be flawless (without grooves).

These requirements were quite challenging as Temponik had very little time to prepare the prototypes due to tight schedules at Bosch Rexroth Fluidtech SAS.

Mission completed in record time on a fully working prototype

When applying the TempoForm method, Temponik hardly ever guarantees to deliver prototypes with completely airtight chambers. This message was, of course, immediately brought to the attention of Bosch Rexroth Fluidtech SAS. Nonetheless, they quickly found their way around the problem. Small amounts of glue were added to the critical areas, and after some polishing the prototypes were ready for testing. The end customer experienced a fully working prototype. It was airtight, and it had exactly the characteristics he had hoped for. The prototypes thus passed the harsh tests, proving that TempoForm is also suited to more challenging applications.

Impressed by the short reaction time

Seen from Project Manager Simon Garrigues point of view the project was very successful. “We were quite impressed by the reaction time of Temponik and the efforts they made in order to meet our requirements. I know they had very little time to prepare our prototypes, and – with this in mind – we were very satisfied with the results. We would not hesitate to order other prototypes from Temponik, if we should receive new enquiries for fully functional prototypes similar to the pneumatic chamber,” says Simon Garrigues.

The prototypes were produced using the TempoForm methode.
