Garrandale delivers air decay test machine solution

Garrandale delivers air decay test machine solution Garrandale Engineering has worked closely with Oxford based exhaust manufacturer UYS Limited to develop a bespoke air decay test machine, which is used by the company at its manufacturing facility to test the integrity of the weld on all of the exhaust systems manufactured by UYS. A leaking exhaust can lead to toxic fumes entering the passenger compartment so it is vital that the testing procedure has no margin for error.

A commonly used leak test solution is air decay leak testing, which is an economical and quantifiable method of testing whether a product passes the specified leak limit. Whilst this is a common type of machine that carries out an industry recognised test, the need for a bespoke solution came from the fact that UYS, who manufacture the exhaust systems for the vehicles that come off the Honda production line in Swindon, are required to test a number of exhaust systems for different vehicles.

As a result, Garrandale provided a solution that incorporated a range of interchangeable tooling modules which utilise a quick release system. In the short term this allows the modules to be changed quickly and easily for each different exhaust system, saving valuable time in the testing procedure. However, it also provides a long term solution as any future changes to the vehicle model or component can be accommodated through new tooling rather than having to buy a brand new machine.

Garrandale has now supplied eight air decay test machines to UYS, together with three additional air underwater test machines which are used for the detection of zero leaks on the integrity of the welded parts. As a complete solution the benefits are extensive as they provide a thorough test solution which eliminates the margin for error. This gives additional benefit of quicker turnaround times for the operator and the resultant reduction in the cost of the testing procedure are also proving to be significant.

Garrandale’s Engineering Division has been providing innovative solutions to a wide range of problems for many years in industries ranging from automotive and medical to rail vehicle assembly and rocket science.
