Strack-Norma Mould insert leak pressure unit reduces danger, costs
Testing the seals before mounting the tool.
Checking the leak tightness of temperature control circuits has practically become a daily affair for toolmakers. Up to now, the level of technology only allowed checks when the tool is installed. This problem is said to have led Strack-Norma to develop its Z7755 mould insert leak pressure unit.

If the tempering medium leaks, the tool has to be dismounted from the machine, the leak has to be found. and the tool needs cleaning before remounting. This costs money and time. The company explained that its unit can significantly increase the reliability of a tool’s leak tightness, and lower costs versus the traditional test procedure some 90% by testing tools before installation.
The unit comes with a test body and three adapter sizes, which are delivered in pairs. These can be used for the common sizes M5/M6, M8/M10 and M12. Components are stored in a handy suitcase, the company said. A test pump, a connecting coupling and a dummy plug can be ordered optionally.
