After many years of development, the first mass finishing vibrator was launched in 1956. This was a little technical sensation, which resulted in an enormous boost for Trowal by means of the extremely enlarged range of applications. The coming of the vibrator, with a performance more than ten times higher than conventional barrels, was also the beginning of the end of the hexagonal barrel de-burring and polishing technique. Then, in quick succession, many trail-blazing inventions, which have determined the shape and future of surface finishing, were launched by the Walther Trowal organisation. Examples of these are outlined below:
In the course of increasing environmental awareness, a special waste water system for surface finishing was developed. With the introduction of re-cycling technology and the use of ultra-modern, centrifugal filtering machines, "mass finishing without waste water" became a reality. Up to this point it was considered to be an impossibility.
The latest development by Trowal is the M-TMD drag finishing machine, which is used for high-quality and delicate work pieces consisting of extremely hard, difficult to machine materials.
