The predecessor of Diametal started around 1930 and made tools for the diamond cutting industry, which 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’s these home workers became too expensive and the diamond sector moved on. As a result Diametal started renovating and making spare parts 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 technical plastics started becoming more and more important. Diametal was sold in 2005 to the current owner.
