The key to successful leak testing is in
the design and manufacture of the fixture and sealing system. TQC
has many years experience of seal and fixture design and our expertise
in this area enables us to engineer representative, reliable and
repeatable leak test equipment. TQC supply a standard series of
solutions called Series 10 through to Series 40, further information
on these is available on the TQC Leak Test Systems webpages.
The standard series of TQC leak test machines
can be enhanced with the following features:
- Leak location – water dunk or trace gas
- Component marking – impact character,
dot matrix, inkjet or adhesive labels.
- Blockage and flow tests.
- Process fault detection, eg. core sand
debris and excess flash.
- Parts present check, eg. Integral seals,
brackets and screws etc.
- Measurement and gauging
- Integrated sub-assembly operation, eg.
Seal insertion, core plug insertion, automatic screw driving etc.
- Sub-assembly component performance and
function tests, eg. Electrical testing of sensors, switches and
- Multi-cavity testing, eg. Combined vacuum
and positive pressure testing , internal leakage testing, low
and high pressure testing.
- Serial numbering and data logging for
product traceability, SPC and quality control requirements.
