SHOCK ABSORBER TESTING MACHINES

Precision - a word that keeps on getting 
thrown around often in the world of 
engineering. However, when it comes to 
shock absorber testing, precision isn’t a 
luxury-it’s survival.
Every curve, every jolt, every rebound of
a shock absorber must be captured,
tested, and analysed to microscopic
exactness. Gone are the days when
manual testing could keep up.
The role of shock absorbers in today’s
high-speed automotive innovation and
precision engineering is to provide safety, 
comfort, and performance protection.
But how can we make sure that these
absorbers meet the high standards 
required by modern vehicles? This is where 
PLC automation becomes a useful tool.

The old-fashioned testing methods, which were
cumbersome, unreliable, and laborious, have been
replaced by PLC-based automation systems. Imagine
a testing line with the capacity to think, adapt and
respond in real time. The precision of Programmable
Logic Controllers (PLCs) is not solely a promise,
but rather adherence to standardised protocols.
At Messung Industrial Automation, we aren’t just 
manufacturing automation controllers-we’re crafting
the intelligent nervous systems that power modern
industrial machinery. Our PLC-controlled shock 
absorber testing machines are powered by the NX-ERA 
JET PLC.
These tests provide new perspectives on accuracy,
speed and efficiency in an Industry 4.0 world.

How PLCs Enhance Shock Absorber 
Testing
There has been an evolution in the science of testing shock absorbers. Let’s understand how smart and 
compact PLCs can automate and optimise critical testing stages by providing consistency, control, and 
clarity.
