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 sniffing.
• 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 devices.
• 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.
