The predecessor of Diametal started around 1930 and made tools for the diamond cutting industry, what explains the name Diametal.
Herentals and surroundings would become a center for cheap diamond cutting and grinding with hundreds of companies and home workers.
Around the 1970 ties these home workers became too expensive and the diamond sector moved on. As aresult Diametal started renovating and making spareparts for the production industry in general. In 1984 Diametal became a limited company: conventional milling , turning, threading, keyseating,… in short machining became the core activity.
In 1998 Diametal bought the first CNC machine and more employees were hired to a total of 5 employees. From that year on CNC machining became the first choice.
A year later, in 1999, a 900 m² production facility at the Noordervaart 33 in Herentals was build. Next to metal also technical plastics became more and more important. Diametal was sold in 2005 to the current owner.
