SMARTER SURFACE PROTECTION – PLC AUTOMATION IN AUTOPHORETIC COATING PLANTS
                     SMARTER SURFACE PROTECTION – PLC 
AUTOMATION IN AUTOPHORETIC COATING PLANTS
www.messungautomation.co.in 
In modern manufacturing, surface coating is not 
just cosmetic-it’s essential for durability, corrosion 
resistance, and performance. Autophoretic coating 
(also known as
A-coating) has emerged as a water-based, eco-
friendly alternative to electro-coating. When 
combined with
PLC-based automation, it becomes a powerful,
scalable solution for high-quality, uniform metal 
finishing.
Because let’s face it—metal without proper 
protection
is like a knight without armour. And when it comes 
to smart, sustainable coating, autophoretic coating 
is the unsung hero. Pair this eco-warrior coating 
with PLC automation, and what you get is nothing 
short of magic. At Messung Industrial Automation, 
we believe the perfect coat is not just about shine-
www.messungautomation.co.in it's about smarts, speed,
and sustainability.
What is Autophoretic Coating?
It’s a process where metal parts are dipped
in a reactive water-based solution.
A self-depositing layer forms on the surface
without electric current. Unlike traditional
methods, A-coating lets chemistry take
the wheel.
Why Industries Are Making
the Switch
It avoids the need for heavy electric setups
and provides uniform coverage even in 
complex
geometries. Since it is water-based, it is very
environmentally friendly.

Where Is It Being Used?
From under-the-hood car parts to
refrigerator frames, A-coating is used in:
•  Automotive parts
•  Appliance components
•  Agricultural and construction machinery
•  General industrial structures
Its simplicity belies its power, ushering in
a cleaner, smarter way to protect surfaces
without compromising on quality or cost.

Role of PLC in the Coating Plant
In autophoretic coating, precision begins with automation: the Programmable
Logic Controller (PLC)-the central nervous system of your plant.
Precision Process Circulation & Filtration Mastery –
Automation – PLC systems manage:
The PLC helps everything work •  Fluid circulation
together: •  Filtration cycles
•  Tank temperature •  Solution replacement timing
•  Solution pressure & pH levels Synchronisation with
•  Cycle timing for each dip and Process Controllers – 
rise
Everything moves with precision.
Material Handling Magic – No drips, no downtime.
Our PLC guides parts through:
•  Degreasing
•  Surface conditioning
•  Coating dip
•  Rinsing & curing
