Leak testing machine is a special purpose
machine and it will be specially design and manufacture to
observation and analysis of minor leaks in shock absorber
tube which is Automotive Component. Now a days user
observation and checking method is manual i.e. operator is
visually checks tubes. Because of this there are some field
concerns find in shock absorber and due to this reason they
need some special machine to carry out this operation. This
machine is a combination of electronics, electrical and
pneumatic like PLC, SMPS, single filters, MCB’s, solenoid
valves, pneumatic cylinder, air FRL unit, air buster, digital
pressure, switches, reed switch sensor, optical sensor, push
buttons, indication lamps, digital counter, etc. Basically
operating system for this machine will be as; Lock shock
absorber tube by using push button i. e. cycle start then feel
air in shock absorber tube for reset time. Then cut air
supply now check air drop by using feedback system
through digital procedure switch. If the tube is leak then the
pressure will be drop and digital pressure switch gives
digital input in PLC. According to PLC program logic PLC
gives result output with indications either the tube is leak or
not and this will insure the rejection of tube from in field.

PLC, Shock Absorber Tube, Leak Test, FQA
Due to manual testing the system is less accurate and also
takes time. At the final FQA it is found the tubes have
leakage and rejected by FQA to remove/replace the tube.
The aim of the project was to address the pressing
challenges of increase production rate with more
accurately and efficient operation of Leak testing
machine. Leak testing machine is a special purpose
machine and it will be specially design and manufacture
to observation and analysis of minor leaks in shock
absorber tube in which we increase the production rate. If
any failure occurred in hardware then work done can
carried out manually. As shown in Table 1, we come
across the difficult parameter of tube testing and we
obtained solution upon it. Hence we achieve all our
objectives and overcome all the drawbacks we have seen
in trial and error experiment.
