J Tolonen Services cc



J Tolonen Services cc was established 1999 to serve companies, which have a requirement for high level engineering support but do not have possibility to have their own specialists full time employed. We are located in sunny South Africa with good communication links to all parts of the world. Our customer base is located on about every continent excluding Antarctica.

Our engineering software was initially developed for our work to be highly productive and to be able to provide high level service to our customers. As the software was growing we identified that there are companies who have use for them and after some upgrading they were released for sale. Currently we are the leading independent supplier of bellows' design software in the world.

We have collected some images of our work and software. Please be free to have a look.
